Think about the large amount of plastic that the average household throws away on a daily basis. The recycling of plastic is increasing, yet most plastic is recycled during manufacturing of the containers; not as post-consumer recycling. For example, trimmings from plastic bottles are reground and reprocessed into new ones. Recycling this material is expensive. The materials are very light, making transport costs per tonne very high.
Plastic recycling is more complicated, but using recycled rather than new plastic can save on average two tonnes of CO2. Furthermore, plastic can be recycled over and over again. This type of recycling material is unlikely to be adversely affected by PLA, which can't currently be processed by mainstream recyclers, until it makes up a far greater percentage of plastic than it does now. The best option would be to develop a separate recycling stream for PLA. Plastic re-use is carred out mechanically in Tehran. However, this simple method is not scientifically approved for collection, separation, recycling process and products generation.
The recycling of such materials like plastic is processing mixed waste now! In addition, our system uses both post-consumer and post-industrial commingled plastic. Recycling is bound to realize a saving in production costs, conserve our limited resources, and alleviate environmental pollution. The recycling of these materials is lagging well behind paper and cardboard, as people are confused about what recycling is available in their areas. There are other challenges for plastic recycling, such as the fact that it can release toxic chemicals into the atmosphere, and that it is more expensive to recycle some plastic than to create a new product from petrochemicals.
The recycling of plastic materials is becoming an increasingly large business. In fact, just in the period from 1990 to 1999, the number of recycling plants grew from 923 to 1,677 - an amazing 81% increase. The recycling of plastic materials is second only to paper in complexity, but a success story is a success story. The Keene Recycling Center is on pace to collect record amounts of recyclables this year, among them PETE or PET plastic. This process of recycling is the act of parting waste plastics and used scrap to recover materials that are usable for the manufacturing industry. Plastic contains many fibers due to its large amount of layered chemical structures and resins that have been melted down to get the smooth surface as you can see on grocery bags.
