It would also be great if you use different colors and shapes for your recycling bins, and also stick shiny, attention-grabbing labels or stickers to each container, so that the students and school staff will know what to throw in each of them. Although some people may get confused about where to put which item at the start, most of them will probably get used to it in the long run. In the US, the Environmental Protection Agency (EPA) and other state departments manage and oversee the laws which regulate the disposal of hazardous wastes. The EPA requires that hazardous wastes be handled with extra precaution, and should also disposed at designated facilities. Among the materials that need to be handled with extra care include medical waste, commercially-generated waste, electronic items and components, radioactive materials, ammunition, and other unknown materials. It can either rigid or flexible, opaque or transparent. It can also be made to look like silk, wood or leather. It can be made into plastic toys, containers or even heart valves. There are 10,000 different types of plastics, and the raw materials for plastic are natural gas or petroleum. The process of recycling plastic starts from the time the material is made, to the time it is once again reused as a new product after the recycling process. While before only ten percent of discarded tires were actually recycled today more than eighty percent of used tires today now make their way into a recycling facility. Hundreds of different applications have now been developed for recycling and re-using used car components and materials. It s estimated that 1 in 4 of the used tires today are re-treaded, and used again in another motor vehicle somewhere else. Recycling Helps Save Precious Natural Resources The act of recycling, even within your own home or office, can actually help save precious natural resources. If your recycle old newspapers, junk mail, cardboard, Styrofoam and other materials, you help protect the air, and help save trees from being cut down. The Lack Of Resources Encouraged Recycling During Wartime The outbreak of two major world wars in the early 20th century brought crippling shortages of precious natural resources. These major world-changing occurrences dipped available resources, and forced governments to encourage recycling. During World Wars 1 and 2, governments urged their citizens to conserve wood, paper, textiles, fiber, and even donate metals and precious jewelry.
