    Did you know that galvanization is the process of applying a protective zinc coating to steel or iron to prevent rusting? The most common method in Gi Coil Sheet metal fabrication shops is hot-dip galvanizing. This is the process of submerging metal parts in a bath of molten zinc to protect the metal. This protection occurs in three different ways: The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron. It acts as a sacrificial anode, which is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal from corrosion. This means that if the coating is scratched, the exposed steel or iron will be protected by the remaining zinc. The zinc protects its base metal by corroding before iron. Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing. Galvanized Steel Gi Sheet is among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating. The zinc protects the base metal by acting as a barrier to corrosive elements, and the sacrificial nature of the coating results in a long-lasting and high-quality steel product. This versatility makes it applicable to a variety of projects and industries, including agriculture, solar, automotive, construction, and so on. Below, we aim to provide a comprehensive description of how galvanized steel is processed, different galvanization methods, its benefits, and how it is used in these various industries. WHAT IS ZINC ALUMINUM-MAGNESIUM COATED STEEL This Zinc Aluminum Magnesium Steel Coils which is also called ZAM coated steel is one newly developed with coating layers of 100-450g +/-10g which owns very strong corrosion-resistant ability. And zinc aluminum-magnesium coated steel is a new type of corrosion-resistant coated steel sheet consisting mainly of zinc, about 11% aluminum, 3% magnesium and trace amounts of silicon. Our Zam Coils adds Al, Mg, Si to the conventional Zn plating, and the these added chemicals elements improve the corrosion resistance. That is, in addition to the previous Al addition, added to the zinc aluminum magnesium coil products have the significant effect on the Mg, in addition, to meet the addition of Si, so that rust effect can be improved. Si improves the corrosion resistance of the coating layer containing Al while further improving the corrosion effect by the combination with Mg. This Zin Aluminium Magnesium steel feathers superior corrosion-resistance on the surface, bend processed parts, ammonia environment, cut edge, drawing-processed parts. And it’s HS code is 72109000. Zn Al Mg Alloy Coils Advantages 1. Excellent anti-rust performance! The rust-proof performance of the flat part is no need to speak. 2. The rust resistance of the end face is also excellent. 3. Moreover, alkali resistance is also excellent. This zinc aluminum magnesium steel coil in comparison with hot-dip galvanized steel and hot-dip galvanized 5% aluminum alloy steel, can achieve the same corrosion resistance but use less plating layers. In addition, because of its excellent resistance to red rust, it can be used to be instead of stainless steel or aluminum plate. 4. Excellent processing property performance! Bending portion, the stretching portion is also hard to rust, surface processing is not rare injuries, very beautiful. 5. Weldability, paint is also very good. 6. Withstand the rigors of processing with the plating adhesion. In addition, the coating hardness is high, with excellent resistance to damage. 7. Super VA’s new material can greatly reduce costs and shorten delivery time due to the no need for post-plating. 8. May also be a substitute for stainless steel and aluminum. 9. It is resistance to severe conditions of the processing of adhering. In addition to high hardness coating, with excellent resistance to damage. With a history that stretches back over 150 years, there are innumerable examples of galvanised steel in use in many environments, which prove its performance. Galvanized Tube is all around us, in a whole variety of industries including road, rail, energy plants, oil and gas, agriculture, water and waste and sports and leisure. It can play an important role for buildings, bridges, facades, signal gantries, gates, balconies and even sculptures. Wherever there is a risk for corrosion of steel, galvanising should be used. An average coating thickness of 85 microns, the same thickness as a sheet of A4 paper, can protect a steel structure for the better part of 100 years. One of the inherent benefits of hot dip galvanizing is that when clean steel that is greater than 6mm thick is submerged into molten zinc, it will develop a minimum mean coating of 85 microns.

      Evolving from the numerical control (NC) machining process which utilized punched tape cards, CNC machiningis a manufacturing process which utilizes computerized controls to operate and manipulate machine and cutting tools to shape stock material—e.g., metal, plastic, wood, foam, composite, etc.—into custom parts and designs. While the CNC machining process offers various capabilities and operations, the fundamental principles of the process remain largely the same throughout all of them. The basic CNC machining process includes the following stages: Designing the CAD model Converting the CAD file to a CNC program Preparing the CNC machine Executing the machining operation CAD Model Design The CNC machining process begins with the creation of a 2D vector or 3D solid part CAD design either in-house or by a CAD/CAM design service company. Computer-aided design (CAD) software allows designers and manufacturers to produce a model or rendering of their parts and products along with the necessary technical specifications, such as dimensions and geometries, for producing the part or product. Designs for CNC machined parts are restricted by the capabilities (or inabilities) of the CNC machine and tooling. For example, most custom CNC machine parts tooling is cylindrical therefore the part geometries possible via the CNC machining process are limited as the tooling creates curved corner sections. Additionally, the properties of the material being machined, tooling design, and workholding capabilities of the machine further restrict the design possibilities, such as the minimum part thicknesses, maximum part size, and inclusion and complexity of internal cavities and features. Once the CAD design is completed, the designer exports it to a CNC-compatible file format, such as STEP or IGES. CNC Machining Tolerances Tables When specifying parts to a machine shop, it's important to include any necessary tolerances. Though CNC machines are very accurate, they still leave some slight variation between duplicates of the same part, generally around + or - .005 in (.127 mm), which is roughly twice the width of a human hair. To save on costs, buyers should only specify tolerances in areas of the part that will need to be especially accurate because they will come into contact with other parts. While there are standard tolerances for different levels of machining (as shown in the tables below), not all tolerances are equal. CAD File Conversion The formatted CAD design file runs through a program, typically computer-aided manufacturing (CAM) software, to extract the part geometry and generates the digital programming code which will control the CNC machine and manipulate the tooling to produce the custom-designed part. CNC machines used several programming languages, including G-code and M-code. The most well-known of the CNC programming languages, general or geometric code, referred to as G-code, controls when, where, and how the machine tools move—e.g., when to turn on or off, how fast to travel to a particular location, what paths to take, etc.—across the workpiece. Miscellaneous function code, referred to as M-code, controls the auxiliary functions of the machine, such as automating the removal and replacement of the machine cover at the start and end of production, respectively. Once the CNC program is generated, the operator loads it to the CNC machine. Machine Setup Before the operator runs the CNC program, they must prepare the CNC machine for operation. These preparations include affixing the workpiece directly into the machine, onto machinery spindles, or into machine vises or similar workholding devices, and attaching the required tooling, such as drill bits and end mills, to the proper machine components. Once the machine is fully set up, the operator can run the CNC program. Machining Operation Execution The CNC program acts as instructions for the CNC machine; it submits machine commands dictating the tooling’s actions and movements to the machine’s integrated computer, which operates and manipulates the machine tooling. Initiating the program prompts the CNC machine to begin the CNC machining process, and the program guides the machine throughout the process as it executes the necessary machine operations to produce a custom-designed part or product. CNC machining processes can be performed in-house—if the company invests in obtaining and maintaining their own CNC equipment—or out-sourced to dedicated CNC machining service providers. Types of CNC Machining Operations CNC machining is a manufacturing process suitable for a wide variety of industries, including automotive, aerospace, construction, and agriculture, and able to produce a range of products, such as automobile frames, surgical equipment, airplane engines, gears, and hand and garden tools. The process encompasses several different computer-controlled machining operations—including mechanical, chemical, electrical, and thermal processes—which remove the necessary material from the workpiece to produce a custom-designed part or product. While chemical, electrical, and thermal machining processes are covered in a later section, this section explores some of the most common mechanical CNC machining operations including: Drilling Milling Turning CNC Drilling Drilling is a machining process which employs multi-point drill bits to produce cylindrical holes in the workpiece. In CNC drilling, typically the CNC machine feeds the rotating drill bit perpendicularly to the plane of the workpiece’s surface, which produces vertically-aligned holes with diameters equal to the diameter of the drill bit employed for the drilling operation. However, angular drilling operations can also be performed through the use of specialized machine configurations and workholding devices. Operational capabilities of the drilling process include counterboring, countersinking, reaming, and tapping. CNC Milling Milling is a machining process which employs rotating multi-point cutting tools to remove material from the workpiece. In CNC milling, the CNC machine typically feeds the workpiece to the cutting tool in the same direction as the cutting tool’s rotation, whereas in manual milling the machine feeds the workpiece in the opposite direction to the cutting tool’s rotation. Operational capabilities of the milling process include face milling—cutting shallow, flat surfaces and flat-bottomed cavities into the workpiece—and peripheral milling—cutting deep cavities, such as slots and threads, into the workpiece. CNC Turning Turning is a machining process which employs single-point cutting tools to remove material from the rotating workpiece. In CNC turning, the machine—typically a CNC lathe machine—feeds the cutting tool in a linear motion along the surface of the rotating workpiece, removing material around the circumference until the desired diameter is achieved, to produce cylindrical parts with external and internal features, such as slots, tapers, and threads. Operational capabilities of the turning process include boring, facing, grooving, and thread cutting. When it comes down to a CNC mill vs. lathe, milling, with its rotating cutting tools, works better for more complex parts. However, lathes, with rotating workpieces and stationary cutting tools, work best for faster, more accurate creation of round parts. CNC Metal Spinning Close cousins to lathes, CNC spinning lathe machines involve a lathe set with a blank (a metal sheet or tube) that rotates at high speeds while a metal spinning roller shapes the workpiece into a desired shape. As a “cold” process, CNC metal spinning forms pre-formed metal—the friction of the spinning lathe contacting the roller creates the force necessary to shape the part. How Does a Swiss Machine Work? Swiss machining, also known as swiss screw machining, uses a specialized type of lathe that allows the workpiece to move back and forth as well as rotate, to enable closer tolerances and better stability while cutting. Workpieces are cut right next to the bushing holding them instead of farther away. This allows for less stress on the part being made. Swiss machining is best for small parts in large quantities, like watch screws, as well as for applications with critical straightness or concentricity tolerances. You can find out more about this topic in our guide on how swiss screw machines work. How Does a 5 Axis CNC Machine Work? 5 axis CNC machining describes a numerically-controlled computerized manufacturing system that adds to the traditional machine tool’s 3-axis linear motions (X, Y, Z) two rotational axes to provide the machine tool access to five out of six part sides in a single operation. By adding a tilting, rotating work holding fixture (or trunnion) to the work table, the mill becomes what is called a 3+2, or an indexed or positional, machine, enabling the milling cutter to approach five out of six sides of a prismatic workpiece at 90° without an operator having to reset the workpiece. It is not quite a 5-axis mill, however, because the fourth and fifth axes do not move during machining operations. Adding servomotors to the additional axes, plus the computerized control for them – the CNC part –would make it one. Such a machine- which is capable of full simultaneous contouring- is sometimes called a “continuous” or “simultaneous” 5-axis CNC mill. The two additional axes can also be incorporated at the machining head, or split – one axis on the table and one on the head. CNC Lathe Operator Training To handle a CNC lathe, a machinist should have completed a set amount of coursework and earned appropriate certification from an accredited industrial training organization. CNC turning machining training programs will usually involve multiple classes or sessions, offering a gradual instruction process broken up into several steps. The importance of adhering to safety protocols is reinforced throughout the training process. Beginning CNC lathe classes might not include hands-on experience, but they may include familiarizing students with the command codes, translating CAD files, tool selection, cutting sequences, and other areas. A beginner CNC lathe course may include: Lubrication and scheduling lathe maintenance Translating instructions into a machine-readable format and loading them into the lathe Establishing criteria for tool selection Installing tools and parts for handling the material Producing sample parts, like die-casting parts Later CNC lathe training typically involves actual lathe operation, as well as machine adjustments, program editing, and the development of new command syntax. This type of lathe machine training can include courses on: Figuring out where edits are needed from comparing sample parts to their specifications CNC programming edits Creating multiple cycles of test components to refine the results of edits Regulating coolant flow, cleaning the lathe, and repair and replacement of tools CNC Machining Equipment and Components As indicated above, there is a wide range of machining operations available. Depending on the machining operation being performed, the CNC machining process employs a variety of software applications, machines, and machine tools to produce the desired shape or design. Types of CNC Machining Support Software The CNC machining process employs software applications to ensure the optimization, precision, and accuracy of the custom-designed part or product. Software applications used include: CAD CAM CAE CAD: Computer-aided design (CAD) software are programs used to draft and produce 2D vector or 3D solid part and surface renderings, as well as the necessary technical documentation and specifications associated with the part. The designs and models generated in a CAD program are typically used by a CAM program to create the necessary machine program to produce the part via a CNC machining method. CAD software can also be used to determine and define optimal part properties, evaluate and verify part designs, simulate products without a prototype, and provide design data to manufacturers and job shops. CAM: Computer-aided manufacturing (CAM) software are programs used extract the technical information from the CAD model and generate machine program necessary to run the CNC machine and manipulate the tooling to produce the custom-designed part, such as stamping partscustom plastic parts, etc. CAM software enables the CNC machine to run without operator assistance and can help automate finished product evaluation. CAE: Computer-aided engineering (CAE) software are programs used by engineers during the pre-processing, analysis, and post-processing phases of the development process. CAE software is used as assistive support tools in engineering analysis applications, such as design, simulation, planning, manufacturing, diagnosis, and repair, to help with evaluating and modifying product design. Types of CAE software available include finite element analysis (FEA), computational fluid dynamics (CFD), and multibody dynamics (MDB) software. Some software applications have combined all of the aspects of CAD, CAM, and CAE software. This integrated program, typically referred to as CAD/CAM/CAE software, allows a single software program to manage the entire fabrication process from design to analysis to production. What is a CNC Machine? Types of CNC Machines and custom CNC precision machining parts Depending on the machining operation being performed, the CNC machining process employs a variety of CNC machines and machine tools to produce the custom-designed part or product. While the equipment may vary in other ways from operation to operation and application to application, the integration of computer numerical control components and software (as outlined above) remains consistent across all CNC machining equipment and processes. CNC Drilling Equipment Drilling employs rotating drill bits to produce the cylindrical holes in the workpiece. The design of the drill bit allows for the waste metal—i.e., chips—to fall away from the workpiece. There are several types of drill bits, each of which is used for a specific application. Types of drill bits available include spotting drills (for producing shallow or pilot holes), peck drills (for reducing the amount of chips on the workpiece), screw machine drills (for producing holes without a pilot hole), and chucking reamers (for enlarging previously produced holes). Typically the CNC drilling process also utilizes CNC-enabled drill presses, which are specifically designed to perform the drilling operation. However, the operation can also be performed by turning, tapping, or milling machines. CNC Milling Equipment Milling employs rotating multi-point cutting tools to shape the workpiece. Milling tools are either horizontally or vertically oriented and include end mills, helical mills, and chamfer mills. The CNC milling process also utilizes CNC-enabled milling machinery, referred to as mill machines or mills, which can be horizontally or vertically oriented. Basic mills are capable of three-axis movements, with more advanced models accommodating additional axes. The types of mills available include hand milling, plain milling, universal milling, and omniversal milling machines. CNC Turning Equipment Turning employs single-point cutting tools to remove material from the rotating workpiece. The design of the turning tool varies based on the particular application, with tools available for roughing, finishing, facing, threading, forming, undercutting, parting, and grooving applications. The CNC turning process also utilizes CNC-enabled lathes or turning machines. The types of lathes available include turret lathes, engine lathes, and special-purpose lathes. What is a Desktop CNC Machine? Companies that specialize in manufacturing CNC machines often offer a desktop series of smaller, lightweight machines. Desktop CNC machines, although slower and less precise, handle soft materials well, such as plastic and foam. They’re also better for smaller parts and light to moderate production. Machines featured in a tabletop series resemble the larger industry standard, but their size and weight make them better suited to small applications. A desktop CNC lathe, for example, that features two axes and can handle parts up to six inches in diameter, would be useful for jewelry and mold-making. Other common desk CNC machines include plotter-sized laser cutters and milling machines. With smaller lathes, it’s important to differentiate between a benchtop CNC lathe machine and a desktop lathe. Benchtop CNC lathes are generally more affordable, but also smaller and somewhat limited in the applications they can handle. A standard CNC benchtop lathe generally includes the motion controller, cables, and basic software. A standard CNC desktop lathe, with a similar basic package, costs slightly more.

    If your business deals with large quantities of materials, you need a reliable and convenient method of storing and transporting them. In that case, look no further than refurbished bulk jumbo bags made from woven plastic. Refurbished bulk bags are sturdy, durable, economical — and they are great for the environment as well. Using refurbished bulk bags help keep plastic out of our landfills, where it would remain for years. The global market has recently picked up on the many advantages of bulk bags — in 2018, the global bulk bag market amounted to about $4.1 billion, and by 2025 that number is expected to climb to about $6.6 billion. But why are bulk bags made of woven plastic? This article covers the advantages of this material, and how different types of bulk bags are used in various industries. Why Are Bulk Bags Made of Woven Plastic? Bulk bags are made of woven plastic fibers — usually a soft thermoplastic material known as polypropylene, though sometimes PVC for extra durability and protection — because of the many advantages they offer: Lightweight: Woven plastic is lightweight — polypropylene is one of the lightest of commercial plastics, and bulk bags typically weigh only 5 to 7 pounds. The lightness of the material makes the bags user-friendly and convenient for storage and transport of materials. Strength: Woven plastic is also incredibly strong and dependable. As the fibers interweave over, under and between one another, they create durable, dense layers that perform impressively even with industrial-sized loads. These properties make bulk bags ideal for the storage and transport of goods because they can lift and store between 500 and 4,000 pounds with ease. Resilience: Another benefit of woven plastic is its resistance to breakdown by many chemicals. Making PP jumbo bags out of woven polypropylene fibers helps improve their lifespans, giving companies many quality uses out of them as long as the bags have the correct safety factor rating. Durability: Woven plastic is also resistant to shrinkage, stretching, humidity and heat. So even in a hot, demanding environment, PP woven bags will keep their shape and retain their ability to hold goods safely and effectively. Watertightness: Woven plastic bags can be specially treated for water-tightness, so they can transport and store goods securely without admitting water that could cause mold or spoilage. Flexibility: Woven plastic is soft and pliable, so woven plastic bulk bags are user-friendly because of their flexibility. They can fold into compact shapes for storage, so they leave plenty of space for work on the warehouse or factory floor. Recyclability: Once businesses have used woven plastic bags as long as possible, the bags can be recycled into other materials. Typically, the plastic is cut into small, manageable chunks and then used in new bags or other polypropylene products. How Woven Plastic Bulk Bags Benefit Each Industry Woven plastic bulk bags provide benefits to a number of industries, such as food PP woven bags, and different types of bulk bags are particularly useful in different applications. Industries commonly use four different types of bulk bags: Open top bulk bags: Open top bulk bags are cubes made of woven plastic on five sides, with the top entirely open. In industries that need to fill bulk bags manually, open top bulk bags are an excellent choice. Duffle top bulk bags: Duffle top bulk bags have extra fabric at the top that allows users to open and close the top inlet completely. Duffle top bulk bags are ideal choices in industries where complete coverage of transported and stored materials is essential. Spout top bulk bags: Spout top bulk bags are similar to duffle top bulk bags except that they have spouts in place of closable fabric. These bags are ideal for industries that need to fill bulk bags quickly, efficiently and with minimal spills. Baffled bulk bags: Baffled bulk bags are similar to open top bulk bags — they are open at the top — but they have additional sturdy interior linings. These lining panels allow the bag to maintain its fixed cubic shape no matter what material it contains or how heavy that material is. Baffled bulk bags are ideal for industrial applications in which bulk bags will be stacked or packed tightly into a small space. Below are a few of the industries in which these different styles of woven plastic bulk bags are beneficial: Agriculture: Bulk bags are incredibly useful in the agricultural industry. Many agricultural products, like seeds, grain and feed, require reliable methods of storage and transport. Bulk bags fill this role efficiently and reliably, and chemical-free food-grade bags are perfect for agricultural products intended for human or animal consumption, such as flours, corn and rice. Spout top bags make pouring easy, and duffle top bags are great options for providing extra protection for consumable products. Also, there are also chemical jumbo bags. Construction: The construction industry often needs to transport and store bulky materials such as sand, gravel, cement, bricks, lumber, nails and other supplies. Construction jumbo bags make an excellent fit for the construction industry because of their strength, durability and safety. Open top bags are great options when bulky materials may not quite fit into the bag space, and baffled bags are smart options when materials need to be stacked for storage or transport. Food processing: The food processing industry makes use of many materials such as flours, grains, sugars, beans and other dry bulk products like potatoes and onions. Food-grade, chemical-free food jumbo bags make excellent transport and storage vessels for these items — and for pet food products as well. Spout top bags make pouring dry bulk products easy, open top bags allow for maximum ventilation, and duffle top bulk bags offer extra protection for food products. Mining: Mining operations need to transport valuable materials such as coal and metal ores, as well as process materials and byproducts like gravel, rock and soil. Durable, flexible mineral jumbo bags offer excellent options for the mining industry. Open tops allow for overfilling at the top of the bag, and baffled bulk bags make stacking and storing mining products convenient and easy. How to Choose the Best Bulk Bag for Your Business Choosing the best bulk bag for your business is often easy and intuitive. Assess the materials your business handles and what some of its specific storage and transport needs are. You can then determine the style of bulk bag that will best fit your company’s requirements. Here are some of the factors you may want to evaluate when deciding on bulk bags: Extra protection needs: When you’re choosing bulk bags, consider whether the products you work with require additional protection, especially as transport jumbo bags. If so, you may want to consider duffle top bags or baffled bags. Duffle top bags allow for complete, secure top closure, and baffled bags provide extra, sturdy side reinforcement for sensitive loads. Filling needs: Your bag-filling requirements will also come into play. Think about whether your operations require extra speed and accuracy in filling bulk bags. You should also consider whether minimizing product losses due to spillage is a high priority. If so, consider investing in spout top bags that can direct the flow of product for a more efficient filling process all around. Load size and shape: When you’re choosing daily jumbo bags, you should also consider the size and shape of the loads they are likely to carry. If loads are bulky and irregularly shaped, think about open top bags, which allow for more flexibility by letting products stick out or slightly overfill the bag as needed. Stacking and space-filling needs: Consider your stacking and space-filling needs as well. If your space is cramped or your product volumes are high, your operations require that your bags stack in efficient cubes with minimal space. If so, consider baffled bags, since their sturdy reinforcing panels allow the bags to maintain regular cubic shapes that stack easily. Partner With Bulk Bag Reclamation for All Your Bulk Bag Needs When you’re looking for bulk bags for your business, partner with Bulk Bag Reclamation. Buying refurbished bulk bags helps your company save money, improve its bottom line and gain quality, reliable bulk bags to keep operations running smoothly. Best of all, you’ll know you’re keeping plastic out of the earth’s landfills — doing your part for the environment and our planet’s habitability.

    The Advantages of Canvas Tarps Tarpaulins (tarps) made of canvas are some of the most versatile tarps on the market today. These tarps can be flame retardant, water resistant, and mildew resistant. Canvas tarps come in several fabric gauges, from 10-ounce to 17-ounce and up. (The higher the number, the heavier and more durable the fabric.) Prices range from around $10 for small, untreated canvas tarps, to hundreds of dollars for large waterproof and fire-retardant models. The tarps come in countless sizes and can be used for a multitude of purposes from painting to landscaping to camping. One of the most common uses of tarps and canvas is to protect furniture, carpets and other items while painting inside or outside. While canvas tarps are more expensive than disposable plastic tarps, they can be used over and over again. Canvas tarps are heavy and will stay in place without a lot of complicated taping and securing, and fit well over curved surfaces. They are usually less slippery than disposable plastic tarps, so they are also safer as there is less chance of injury due to falls. Canvas tarps can be used when landscaping as well. Lightweight waterproof tarps are perfect for protecting grass or plants during snowstorms. Tarps have been used for decades to cover baseball diamonds and football fields during inclement weather; the tarp can be removed as soon as the rain has stopped and play can usually resume immediately. Many of the finest tents are made of canvas. Adventurous and inventive campers can make their own camping accommodations with canvas tarps, straps and a few poles. These structures will provide shade, will be water and wind resistant, and are a fraction of the cost of a regular tent. Canvas tarps are versatile and cost effective. They can be used in many diverse situations and are sturdy and dependable.

Canvas-Tarps Canvas tarps are multi-functional and have various benefits. Some of the benefits of canvas tarps are given below, 1) Environment friendly: Environment-friendly Canvas tarps are made from cotton; this makes canvas tarps eco-friendly in nature. If canvas tarps are properly taken care of then they last longer than poly tarps. You can easily dispose of canvas tarps when they deteriorate and after a certain time they get completely decompose. Canvas tarps are versatile and you can use them over and over again. Once the canvas tarps wear out then you can use it for some other purpose that is not more important like covering your bike or anything else. All these features make canvas tarps environment friendly. 2) Breathable: Canvas tarps are made up of natural materials so it allows air to flow between the individual fibers. This is an important feature because it doesn’t allow the load to rust. Breathable tarps prevent moisture from building on the load. Hence, these tarps are mostly considered for moisture-sensitive loads. The breathable property of canvas tarps makes it a perfect option to cover load in a flatbed truck during warmer weather. Canvas tarps are ideal for securing various equipment like construction, industrial, farming, etc. These tarps are flame retardant and that is why they can be used in places where combustible materials are present. Because of their amazing features and property, they are considered an excellent choice for equipment loads. Canvas tarps can be used in different atmospheric conditions like heat, rain, or snow because they are breathable and water-resistant. They are mostly used in outdoor conditions to cover any kind of equipment or outdoor furniture. You can use these tarps at construction sites to cover and secure construction materials. Canvas tarps are also used to cover farming equipment because they can provide protection against rust. This eventually increases the life span of the logistics equipment. While you are transporting any product that needs to be fresh throughout the journey then canvas tarps are preferred over any other tarps. Canvas tarps are a good option if you want to protect any stationery load. However, canvas tarps should not be used for covering trailers or canopies because they have low tear strength at the seams. These tarps should also be avoided in high UV areas. Canvas tarps will get dirty over a certain period of time. Hence, it becomes important to keep them clean. Canvas tarps are not machine washable. To clean the canvas tarps just wipe the spots with the help of soap or detergent that are specifically designed for cleaning canvas tarps. This way you can easily clean the canvas tarps. The reason why canvas tarps should not be cleaned using laundry washer and dryer is that these tarps are coated with wax and that can stain the laundry washer and dryer.

Canvas tarps are versatile and cost effective.  They can be used in many diverse situations and are sturdy and dependable. Tarps have been around for hundreds of years. The original use for a tarp was on the high seas. Sailors used to cover sheets of canvas in tar to protect goods from salt spray and water damage during transit. Over the years, the tarp has had several various uses, but usually remained as a way to keep dirt, water, and other contaminates off something, whether it was furniture, people, dirt, or any other number of things. Over the years, different materials have been used to make the tarp. Tarps have been made from nylon, canvas, cotton, plastic, polyester, and even metal. Throughout history, the tarp has had its ups and downs. Here are some highlights from the tarp’s history from its earliest days until now. 1400-1600 The tarp was used mainly at sea as a way to protect sailors and the items they transported across the seas. The original name for the tarp was the “tarpaulin.” This name came from combining the two words “tar” and “pall.” The pall was the fabric used by the sailors as a trailer cover. 1600-1900 The tarp moved inland. Many people used tarps for protecting items during travel, such as for covering wagons during moves. During the 1700s, the tarp became used for land travel as a tent covering. The waterproof surface of the tarp helped keep travelers and soldiers warm. 1900-Present During the industrial revolution, the tarp received major changes. The tarp was made from a variety of materials, such as plastics, polyester, rubber, and a variety of other materials. People now used the tarp for nearly anything, from covering the floor to prevent paint splatters to keeping leaks off a roof until the rain stopped. Today, people use the tarp for a variety of uses, including camping, construction, transportation, and protection.

    How Three Revolutionary Fabrics Are Greening the Industry If the holiday sales are tempting you to refresh your wardrobe, consider the environmental footprint of buying a new jacket and throwing away your old one. Today, about 80 billion new pieces of clothing are made each year—400 percent more than 20 years ago, while the world’s population only grew about 30 percent. That growth has a huge environmental cost. The Danish Fashion Institute named fashion “one of the most resource-intensive industries in the world, both in terms of natural resources and human resources.” Designer Eileen Fisher has called it “the second largest polluter in the world… second only to the oil industry,” and while that fact has been disputed, a 2010 research paper found that the industry is responsible for almost 10 percent of global greenhouse gas emissions. Moreover, once clothes have been made and worn for a short while, they’re thrown away. A new report from the Ellen MacArthur Foundation found that cumulatively around the world a truckload of clothes gets dumped every second. The average American tosses about 82 pounds of textiles a year, much of which ends up in landfills or incinerated. Of the clothing that reaches second-hand stores like Goodwill—only 15 percent of all discards—some is recycled into shoddy (filling for cheap furniture) or upcycled into things like denim insulation, but most of it is shipped to poorer countries. However, they too have limits—African countries including South Africa and Nigeria recently banned Western castoffs, which have overwhelmed their markets, causing the decline of their local fashion business. Replacing Old stock fabrics With New Biopolymers Two types of textiles—petroleum-made polyester and field-grown cotton, often woven together—have been the fashion industry’s darlings for decades. “Much of [what we wear now] is a blend of PET, a petroleum-based fiber, and cotton fiber,” says Ramani Narayan, a professor in the Department of Chemical Engineering and Materials Science at Michigan State University. But these hipora fabric have their issues. Cotton, which makes over 30 percent of our clothes’ yarns, is a natural material, but it’s a thirsty crop that siphons 3 percent of the fresh water, and accounts for almost 20 percent of pesticides and 25 percent of the insecticides used in agriculture worldwide, before it’s even picked. Processing cotton—knitting, weaving, and dyeing—also takes water and energy, yielding more pollution. The production of polyester, the demand for which has doubled in the last 15 years, is an energy intensive process that requires a lot of oil and generates harmful emissions, including volatile organic compounds, particulate matter, and acid gases, like hydrogen chloride, all of which contribute to respiratory disease. “Adding PET to a textile gives you better performance—it makes taffeta fabrics more moisture-resistant and gives them more washability,” says Narayan, but these textiles don’t break down naturally, and instead fill up our landfills and oceans. Polyester threads discarded from washing machines have recently been found in fish, including some species we eat. Unless PET threads are decoupled from cotton and recycled, they don’t decompose, but separating fibers is very difficult. That’s where biopolymers come in.  Biopolymers are macromolecules—long chains of smaller molecular units strung together.  These basic units can be amino acids, nucleotides, and monosaccharaides. The most common biopolymer is cellulose, which makes up one third of all plant material on earth. Cotton is 90 percent cellulose, but there are other, less polluting alternatives. Biopolymers can be grown or harvested from other plants like kelp or from living organisms like bacteria or yeast, which produce biopolymers as part of their lifecycle. The resulting fibers can be woven into a variety of textiles akin to polyester, leather, or a cellulose-like yarn. To a certain extent, these materials can sequester carbon from the atmosphere, acting as wearable carbon sinks. And when they’re thrown away, these biopolymers will decompose. Just as a cotton t-shirt will break down in a compost heap after a few years, so will any biopolymer-based textile. “Obviously it’s better to use plants and biomass to make products,” says Narayan, “because then the plants fix the carbon and when you make a product from that you have removed carbon dioxide from the environment.” Using biopolymers in clothing can reduce energy and freshwater use and may help mitigate climate change resources. Plus, as the following examples show, some biopolymers can take the creativity of fashion design process in a whole new direction. Seining Sweaters from the Sea AlgiKnit uses kelp, a type of seaweed, to produce a biopolymer called alginate, which is then used for textile production. Kelp grows all over the world, forming offshore kelp forests. Some kelp species grow quicker than the fastest-growing terrestrial plant, bamboo, and are inexpensive to farm. As it sprouts, kelp cleans water too—absorbing phosphorous, nitrogen, and five times more carbon dioxide than land plants—so farming it near seaside cities can improve polluted local waters. Like any plant, kelp absorbs carbon to grow, so when used in durable materials, it is also a carbon sink. AlgiKnit extracts alginate from kelp by adding certain salts to the seaweed base. After the so-called “salt bath” pulls the alginate from the kelp’s cell walls, the biopolymer is extracted from the seaweed residue, dried into a powder and fused into a yarn that can be turned into a variety of stretch fabric types. “The process is similar to that of synthetic materials, where one long continuous strand is produced,” says Tessa Callaghan, the co-founder of AlgiKnit. “The filament can be plied and twisted to increase strength, or cut into short fibers for other purposes.” AlgiKnit won National Geographic’s Chasing Genius Competition for developing this technology. The team’s big challenge has been to get their end fiber to be strong and flexible enough for use on an industrial knitting machine. It took a lot of experimentation to ensure compatibility between yarns and machines, but one of the team’s goals is to be able to use the yarn in the existing fiber and textile infrastructure, to streamline the new material’s acceptance, Callaghan says. Modern Meadow’s yeast-produced collagen is another biopolymer that is about to make its runway debut in a form of a leather product named Zoa. The New Jersey-based company designs DNA that can yield collagen, the protein that makes up leather. These specially constructed DNA strands are inserted into the yeast cells. As the yeast cells grow and multiply, they produce collagen and other proteins essential in forming leather, which then cluster together to make a triple-helix collagen molecule. The resulting molecules form bundles that are “cooked” in Modern Meadow’s “secret sauce,” resulting in a leather-like material. “We design DNA that can make collagen, the main building block of leather, then we purify it, and then use an assembly process to turn it into leather,” says Susan Schofer, vice president of business development at Modern Meadow. Compared to traditional leather industries, Zoa’s production has a lower environmental impact and more fashion design opportunities. To turn a piece of animal hide into bags, shoes, or pants, it must undergo chemical and physical treatments to remove fats, hair, and other impurities. That processing is ecologically and medically fraught—most leather tanning is done in countries with few or unenforced environmental laws because the effluent from the process contains fish-killing sulfides, carcinogenic chromium, and chlorinated phenols that are linked to bladder and nasal cancers in tannery workers. Using yeast to grow collagen eliminates the animal part of the equation—including slaughter and subsequent hide processing. It yields higher quality materials—perfectly shaped hides without branding marks or scars, and yields very large spans of leather, much bigger than a cow’s body. It also offers nearly endless creative design ideas. The new collagen can be sprayed on top of another minimatt fabric to create never-before-seen leather fashions, like the t-shirt that is currently on display at the Museum of Modern Art in New York as part of its Items: Is Fashion Modern? exhibit. This material can also be embossed or textured in ways that cow or pig leather just can’t. Modern Meadow will be introducing Zoa to market in 2018. The production facilities are already available from related industries such as biofuels. “We use 200,000 or 500,000-liter fermentation tanks [for the yeast],” says Schofer, “So the infrastructure already exists around the globe to take this from lab to commercial levels.”

    The Importance of Your Car’s Wheel Bearings A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction. Wheel bearings are safety critical components designed to sustain radial and axial loads caused by gravitation, acceleration, breaking & cornering forces, so they need to be replaced when they stop working properly. Faulty installation – inappropriate tools such as a hammer or an impact wrench can cause damage to the exterior and or interior of the wheel end bearing causing the wheel bearing to fail prematurely.  Also, re-using the old accessories such as bolts, nuts, circlips, split pins, seals,… instead of replacing them with new ones can cause the wheel end bearing to operate under abnormal or unsafe conditions, increasing wheel end bearing wear and risk of a car accident. Impact damage or poor road quality – all impacts from driving through a pothole, driving over speed bumps or hitting the curbstone can damage a wheel bearing and reduce its lifespan. Poor quality wheel bearing – a wheel bearing is continuously under enormous pressure. Wheel bearings constructed of low-quality materials can have poor heat-treatment, resulting in premature wear and failure. Driving conditions – driving through deep water or mud can cause your wheel bearings to fail. Water, mud or other contaminants such as dust or road salt could get past the seals and enter the bearing, polluting the grease and wearing away the bearings. Car modifications – fitting bigger or wider rims, tires with lower thread walls, stiffer shock absorbers and suspension springs cause higher loads on the wheel bearing and can accelerate wear. Stick to rims, tires, shock absorbers and springs that are specified by the car manufacturer to minimize the impact on the longevity of the wheel bearings. It’s very rare for wheel bearings to fail immediately and completely after you notice the first symptom(s). Having said that, it is best to avoid driving with a worn wheel bearing for any length of time. As we’ve already seen, the wheel bearing is essential for connecting your wheel to your car, and any weakness in this connection could have severe consequences for your drive-axle and steering assembly – as well as for your safety. Replacing your wheel bearings Despite the fact that modern auto bearing are easier to install than previous generations, correct installation, the usage of appropriate tools and respecting the specified torque values are still essential for maximum performance, durability and safety. Therefore, we recommend having your wheel bearings fitted by a professional mechanic that has the skills and the tools to do the job. The content contained in this article is for entertainment and informational purposes only and should not be used in lieu of seeking professional advice from a certified technician or mechanic. We encourage you to consult with a certified technician or mechanic if you have specific questions or concerns relating to any of the topics covered herein. Under no circumstances will we be liable for any loss or damage caused by your reliance on any content. The increasing preference for personal mobility in the post-COVID period will boost the growth of automobiles and components such as agriculture machinery bearing. Additionally, the Indian automotive bearings market is expected to benefit from the shift of production lines of the global automotive bearings manufacturers to the emerging economies. Nachi-Fujikoshi, a prominent manufacturer of automotive bearings, has announced its plan to move its production of general-purpose bearings from Japan and Taiwan to Thailand. The move is to reduce production costs for automotive bearings. The recent introduction of production-linked incentive (PLI) schemes for automotive components by the government of India will play a crucial role in attracting global players to set up manufacturing facilities in India. The growing demand for light-weight and durable bearings from the automotive industry is leading the prominent bearing manufacturers such as SKF India, Schaeffler India, and NRB Bearings to focus on adopting new raw materials, instead of traditional high-grade steel. For instance, SKF India is manufacturing automotive bearings with alloys that are 10%-12% lighter than traditional bearings made from high-grade steel. The vendors are increasing spending on R&D for the development of lightweight technology. In 2019, Schaeffler India spent 1.34% of revenue on R & D. Auto mechanics all over the country take advantage of the public’s limited knowledge about automotive mechanics and engineering. Many drivers assume that their mechanic knows more about the subject of what’s going on with their cars than they do, and feel they have no choice but to trust their “expert” opinions. This happens frequently with recommended part replacements—especially with wheel bearings. Wheel bearings play an integral role in your car’s overall functioning and performance. Wheel bearings can indeed become damaged or worn out over time, and under these circumstances it is critical to replace them if need be. However, this is one of the opportunities that automotive shops seize to upsell their product and services. If you’ve ever heard the phrase, “well, if you’ve replaced one you should replace the other” then you’ve likely overpaid for automotive services. In this article, we’ll talk about the importance of wheel bearings for your car. We’ll also discuss when industrial bearing should realistically be replaced and what you can do to keep your car in excellent condition moving forward. Wheel bearings are critical for your car’s performance. They reside inside a wheel to help the wheel rotate smoothly and competently by decreasing the amount of friction created by other various parts of the drivetrain system. When wheel bearings become damaged or require replacement, it can lead to devastating effects if not replaced properly. When wheel bearings are not replaced with the proper tools, equipment, and attention to detail, it can cause further, more significant damage to the part over time. Bearing assemblies are a simple mechanical design, but their function is essential to the smooth rotation of your wheels. When one wheel bearing goes bad, it can cause a concerning noise coming from your wheel, especially at higher speeds, and it can cause other gradual side effects to your alignment and wheel balance. When Wheel Bearings Need to Be Replaced Wheel bearings are made of tough, durable material, which means that they generally last a long time in cars. However, they can still require replacement under the right circumstances. If you have noticed any strange noises coming from your wheel as you’re driving, consider if any of the following could apply to your car: Accident Damage Although wheel bearings are sturdy parts alone, the impact from an accident can cause the auto wheel bearing to become damaged. After the rough impact of a car accident, especially if the accident was a side impact, it’s common to encounter broken seals in the bearing assembly, which leads to a contaminated bearing. When grease gets inside through a broken seal, it causes too much friction, which can chip the bearings and cause them to begin to malfunction. Improper Installation Wheel bearings need to be replaced under somewhat rare circumstances, including when they are replaced improperly to begin with. Whenever a wheel bearing or a bearing assembly is replaced, the wheels should be balanced and aligned in order to prevent further damage. This can save you a lot of money in the long run, all you need to do is find an honest mechanic! Engineering Defect Automotive engineering is not a perfect science; many vehicle parts come with defects and wear issues. Cars that are well designed generally have fewer defects, but some cars were simply manufactured with a propensity for wheel bearing issues somewhere throughout the course of the vehicle’s life. Usually automotive shops recommend that if one wheel bearing becomes damaged that the corresponding wheel’s bearing should also be replaced (i.e. front driver’s side and front passenger’s side). While this might make sense for the sake of symmetry, depending on the condition of the other wheel bearing it is usually not necessary to replace both for this reason alone. Here at Santa Barbara Autowerks we pride ourselves on honesty and integrity; we don’t offer services or replacements to our clients unless they’re necessary for their safety or will save them money and energy in the future. As one of the highest quality leading dealership alternatives in Santa Barbara, CA, we tailor our services to German-engineered vehicles, making us experts in German vehicle repair and maintenance.

    Peptides vs proteins - what's the difference? If you’re looking for the difference between peptides and proteins, the short answer is ‘size’. Both peptides and proteins are made up of strings of the body’s basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins. But the definition, and the way scientists use each term, is a little loose. As a general rule, a peptide contains two or more amino acids. And just to make it a little more complicated, you will often hear scientists refer to polypeptides – a chain of 10 or more amino acids. Dr Mark Blaskovich from the Institute for Molecular Bioscience (IMB) at The University of Queensland in Australia says approximately 50-100 amino acids is the cut-off between a peptide and a protein. But most peptides found in the human body are much shorter than that – chains of around 20 amino acids. There’s also an important variant of peptide called the cyclotide. As with the peptide and the protein, the cyclotide is also comprised of a string of amino acids, but unlike the others, the ends of a cyclotide are joined together to form a circle. As we’ll discuss below, this structure is important in the manufacture of therapeutic peptide-based drugs. As for proteins, biochemists generally reserve the term for large peptide molecules, which can either be one long chain of 100 or more amino acids – a ‘complex polypeptide’, if you like – or they can be comprised of several amino acid chains joined together. Haemoglobin, found in your red blood cells and essential for carrying oxygen, is such a protein. It’s made up of four different amino acid chains – two with 141 amino acids each and two with 146 amino acids each. Why peptides are the ‘next big thing’ in medical research Biochemists are excited by the possibilities presented by peptides and proteins as pharmaceuticals because they so often mimic exactly the behaviour of a natural ligand – the substance that interacts with the receptor on an enzyme or cell to cause a biological process. This gives peptide drugs the potential to be more precisely targeted, with fewer side effects than small-molecule drugs. Within the body, there are lot of different hormones that react with cells and trigger different biological processes. Often these are peptides, either cyclic versions or straight, linear ones. And then there’s the matter of how fast that peptide breaks down, which causes some stability issues, but in terms of safety, can be a positive. “We think peptides are the future of drugs for reasons of being more selective, more potent and potentially safer, because when a peptide eventually breaks down it just breaks down into amino acids, and amino acids are food, basically,” says Professor David Craik, who leads IMB’s Clive and Vera Ramaciotti Facility for Producing Pharmaceuticals in Plants. There are also manufacturing considerations that make peptides attractive – their length allows them to be chemically synthesised, as opposed to proteins that are generally expressed in yeast or mammalian cells. So that’s peptides. What are the applications for proteins? The most promising application of proteins is as antibodies, which are themselves a form of protein. Particularly in anti-cancer applications, there are a lot of antibodies either in the clinic or under development. Two well-known examples are Herceptin (trastuzumab) for breast cancer, and Humira (adalimumab) for rheumatoid arthritis and other autoimmune diseases. The advantage of using proteins is the same as for the drug applications of peptides – they mimic something that is natural in the body, or replace something that’s missing or damaged. In the case of antibodies, protein-based drugs use the same strategy as the body does to target things. That way the drug can provide the specificity required, while also avoiding the off-target effects that a small molecule drug can have, causing bad side effects. When will we see new peptide-based medications? Stability can be an issue, as peptides can degrade very quickly, and that means it can be difficult to dose a patient with a peptide. And according to your body, peptides and proteins are basically just food, which makes administering peptide drugs in an oral form quite difficult, as the body promptly digests them. “That’s why drug developers often try going from a peptide and mimicking it with a small molecule instead, because the small molecule potentially has better properties for a drug, where the small molecule stay around in the body longer and can be administered orally,” Dr Blaskovich said. But the challenge is to get the small molecule to mimic the peptide. “Billions are spent by the pharmaceutical industry trying to do this,” Dr Blaskovich added. “That’s why if you’re able to come up with drugs that are peptides, rather than having to convert them into small non-peptidic molecules, it’s potentially a much faster way to develop a potent, selective, and apt drug.” The pharmaceutical industry remains sceptical, mainly due to the stability issue, but also the difficulty in getting orally administered peptides to cross the barrier of the gut and be taken up by the bloodstream. But intravenous and subcutaneous use of peptides as drugs is becoming more common. There are around 60 FDA-approved peptide drugs on the market, with about 140 peptide drugs in clinical trials, and over 500 in pre-clinical (before human testing) development. There are agricultural applications too While the stability of peptides is a challenge to be overcome in human use, it’s a double-edged sword, and may be an advantage in some agricultural uses. The speed of degradation of peptides used as insecticides or fungicides means that they are not going to persist in the environment. So creating greater stability of peptides can work both ways. If the stability of the peptide can be tailored, then it can be made to last long enough to work on the crop, but then also to degrade. This means it would not cause the long-term problems of DDT, for example, which can exist for hundreds of years. Why are experts so excited about peptide drugs? Cyclotides - the central focus of Craik’s work - have great potential to address the issues of stability of peptide drugs. As they structurally form a circle, cyclotides do not have the weak point of loose ends that speed up degradation by our digestive enzymes. They are further stabilised by several interlocking cross-links, forming a compact, very stable structure. This helps them reach their target intact, even when taken orally. Blaskovich’s group is working on two promising peptide-based antibiotics to deal with growing antibiotic resistance. The first of these is to enhance the glycopeptide (peptides with sugar molecules on them) antibiotic Vancomycin, by trying to make it a super-vancomycin that more selectively targets bacterial cells. This approach starts with vancomycin as the core, with additional groups added on to interact selectively with the bacterial cell instead of a mammalian cell. The aim is to increase its potency at killing bacteria and reduce the unwanted side effects it has on human cells. The second research program is developing antibiotics that attack Gram negative bacteria - generally considered the more difficult to fight. These peptides are cyclic lipopeptides (peptides with a fatty acid, or lipid, attached) with eight to 10 amino acids. You might have already taken a peptide-based drug One of the best-known peptide-based drugs is exenatide, which is marketed under the name Byetta. It’s used to help control blood sugar levels in type 2 diabetes patients. It works by increasing the insulin production in response to meals and is a synthetic form of the peptide found in the venom of the Gila monster - a species of venomous lizard native to the US and Mexico. It’s a linear peptide containing 39 amino acids that was developed some 10 years ago, and is now widely used. Defining Antiaging Nutraceuticals The term antiaging can incorporate a broad range of nutraceutical possibilities. For the purpose of this article, let’s define antiaging nutraceuticals as those nutracentical ingredients that help to address health and wellness issues associated with aging. In this context, that would potentially include nutraceuticals that can positively impact the aging process itself as well as those that positively impact aspects of human physiology that tend to decline with age, such as joint health and cognitive health. Ahead, we touch on a few promising contenders. The benefits of organic food How your food is grown or raised can have a major impact on your mental and emotional health as well as the environment. Organic foods often have more beneficial nutrients, such as antioxidants, than their conventionally-grown counterparts and people with allergies to foods, chemicals, or preservatives may find their symptoms lessen or go away when they eat organic fruit and vegetable powder. Organic produce contains fewer pesticides. Chemicals such as synthetic fungicides, herbicides, and insecticides are widely used in conventional agriculture and residues remain on (and in) the food we eat. Organic food is often fresher because it doesn’t contain preservatives that make it last longer. Organic produce is sometimes (but not always, so watch where it is from) produced on smaller farms nearer to where it is sold. Organic farming tends to be better for the environment. Organic farming practices may reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy. Farming without synthetic pesticides is also better for nearby birds and animals as well as people who live close to farms. Organically raised animals are NOT given antibiotics, growth hormones, or fed animal byproducts. Feeding livestock animal products increases the risk of mad cow disease (BSE) and the use of antibiotics can create antibiotic-resistant strains of bacteria. Organically-raised animals tend to be given more space to move around and access to the outdoors, which help to keep them healthy. Organic meat and milk can be richer in certain nutrients. Results of a 2016 European study show that levels of certain nutrients, including omega-3 fatty acids, were up to 50 percent higher in organic meat and milk than in conventionally raised versions. Organic food is GMO-free. Genetically Modified Organisms (GMOs) or genetically engineered (GE) foods are plants whose DNA has been altered in ways that cannot occur in nature or in traditional crossbreeding, most commonly in order to be resistant to pesticides or produce an insecticide. Organic food vs. locally-grown food Unlike organic standards, there is no specific definition for “local food”. It could be grown in your local community, your state, your region, or your country. During large portions of the year it is usually possible to find food grown close to home at places such as a farmer’s market. The benefits of locally grown food Financial: Money stays within the local economy. More money goes directly to the farmer, instead of to things like marketing and distribution. Transportation: In the U.S., for example, the average distance a meal travels from the farm to the dinner plate is over 1,500 miles. Produce must be picked while still unripe and then gassed to “ripen” it after transport. Or the food is highly processed in factories using preservatives, irradiation, and other means to keep it stable for transport. Freshness: Local food is harvested when ripe and thus fresher and full of flavor. Some small local farmers use organic methods but may not be able to afford to become certified organic. Visit a farmer’s market and talk with the farmers to find out what methods they use. At the same time, we now have many ways to get organic plant extract. http://www.biowayorganicinc.com/peptide/
