For us modern people who are accustomed to associate plastic with damage to nature, such a title is confusing. On the one hand the plastic is "beloved" of all material environmentalists in their fight to overwhelm us useless amounts of plastic that seems to have no end. Before de gea our eyes immediately climb pictures of flying on plastic bags on trees, mountains of empty plastic bottles, containers of useless appliances and mobile phones, most of which is plastic.
On the other hand there is hope to overcome this problem. The simplest solution, at least until now, was the separate de gea collection of plastics and reuse or old principle "reuse, reduce, recycle", but it only solves part of the problems. It is true that both of nature saving amounts degradable material, which is used over and over again, but the process also requires that processing of raw materials, and especially large amounts of water and is harmless. Production and recycling of plastics requires huge resources. A large part of the oil, electricity generation de gea and water swallowed it and left environmental plastics decompose for several de gea centuries. The decision is in widespread use of biodegradable de gea plastics. PLA is one such plastic. de gea Her name stands for polylactic acid and biodegradable thermoplastic material, which is produced from renewable de gea sources. In the US for use cornstarch and other countries of the world - sugar cane, but other sources rich in starch.
An interesting fact is that the PLA has been known for almost 100 years, when it was used in England as packaging for sandwiches, de gea but sparked commercial interest only in the last few because of its biodegradability and safety. At a temperature of 60 C becomes plastic so be used for products which are not subjected to high temperatures. It made massive containers for microwave ovens and plastic cutlery for restaurants. PLA is used in medicine for many making special degradable sutures, systems, devices, and as artificial network that serves de gea to build new organs from stem cells.
In France, PLA is used as the main binder component in the material for the insulation of buildings. In the US bioplastic PLA is produced by the company NatureWorks. Destroying it's just natural, fast and environmentally. PLA is not recycled and composted but can be destroyed literally de gea in the backyard and used for soil fertilizer. Buried in the ground it degrades without leaving any residues to harmless products.
PLA is a real alternative to petroleum plastics as lactide which is produced may be recovered by fermentation by-products from various agriculturally, such as maize and other rich in carbohydrates.
