The environmental pollution caused by waste plastic: plastic material has penetrated every aspect of daily life, it is common to see packaging supplies, daily necessities, appliance housings and automotive parts and other products, but these products don’t have a long period of use. Packaging supplies and more for one-time use, daily necessities of life cycle is also much less than six months, home appliances and cars eliminated, update speed faster and faster, and therefore will generate a lot of waste plastics annually. Plastic materials for polymers, chemical stability, difficult to degrade in the natural environment, causing serious environmental pollution after being thrown away, the so-called white pollution.
Environmental pollution caused by waste plastic at the same time which caused a huge waste of resources. Synthetic plastics raw materials mainly for the petroleum, natural gas and other petrochemical feedstocks. Recycling of waste plastics can reduce the consumption of oil resources, to achieve austainable development.
Waste recycling industry, economic and social benefits: recycling waste plastics as a measure to save energy, protect the environment, is attracting increasing attention, especially in developed countries, who work started early and have received significant benefits.
Oil reserve are less and less, recycled plastic also means oil generation. Melt granulation of waste plastics, plastic raw materials to ease supply and demand, but also save a lot of the country’s crude oil imports in foreign currency. In addition, because the vast majority of non-degradable plastic, over time, can cause serious white pollution, destruction of the ecological environment of the Earth. The plastic recycling can alleviate pollution problems. After the waste plastics processed into granulates, the material still has a good overall performance, meet blown firm, drawing, trombone, injection molding, extrusion profiles and other technical requirements, widely used in plastic products. Because the priced advantage of recycled plastic prominent benefits are obvious, domestic waste plastics recycling market booms. At present, there are tens of thousands of various types of waste recycling business.
