Recycling is a very important process, wherein the waste is converted back into a raw material for manufacturing new products. So, the generation of waste and production of natural resources is reduced.
But how many times can you actually recycle paper, glass, plastic or metal? Information on this subject is posted on http://rodovid.me/razdelnyi_sbor_musora/skolko-raz-mozhno-pererabatyvat-materialy-kotorye-my-ispolzuem.html.
Glass: Glass is 100% recyclable indefinitely and does not lose its properties. The only limitation is the color. Green glass container can never be used to obtain a transparent container. It can be a problem for reuse, if all containers are piled to together for recycling. In many European countries, glass containers are sorted by color. For manufacturers of glass color is a very important point, and sorting by color can play a key role in improving the efficiency of the whole system of recycling glass.
Paper: Paper can be recycled forever. Cellulosic fibers are worn each time during the production of new paper. The cellulosic fiber may be used repeatedly about six times. This means that it is important to include the re-fiber feed in the new production process.
Metals. Metals can be recycled indefinitely as glass. Essentially, steel or aluminum from a car or a washing machine each time can become a raw material for new products. For example, the batteries can be re-used again and again to produce new batteries, without resorting to mining.
Plastics. Plastic is one of the most common materials that pollute our planet on a large scale. It can be reused for a new plastic. The recycling of plastic is a high-temperature process, which degrades the quality of the material. Therefore, this process can be repeated only about 4-5 times. However, if plastics are recycled into the paved roads, it may be the last point of their use.
