Generally speaking,plastic is of light weight, high strength, good wear resistance, economical, etc., and thus in the production, life has been widely used. But after using plastic will generate a lot of waste plastics polluting the environment. This paper analyzes the waste plastics recycling technology implementation method is proposed to solve the problem of waste plastics recycling is the main way, not only to solve environmental pollution problems, but also make full use of resources.
As the plastic with a light, inexpensive, high strength and easy processing and excellent performance in the production and life has been very widely used. At the same time, environmental pollution caused by plastic waste has become a global problem. Plastic garbage light and bulky, they are after the landfill does not decompose, causing land compaction, hinder crop breathe and absorb nutrients, making cuts; residual film of toxic additives and PVC will be enriched in vegetables and grain and animal body; the action of ultraviolet light and combustion, their emissions of CO, vinyl chloride monomer (VCM), HCl, methane, NOx, SO2, hydrocarbons, aromatic hydrocarbons, alkaline sludge, dust, water and air pollution , incineration of chlorinated plastics releases dioxin and other harmful substances.
Processing of waste plastics become more and more urgent and necessary . Solve the problem of waste plastics recycling is the main way, including recovery and recycling are two ways. Recycling of waste plastics mainly refers to the concentration, transport, sorting, washing, drying process, only the first recovery, regeneration or to use. Specific process of recycling: waste products→recycled products, recycling waste→Recovery→ →then recycled products.
Additionlly, promote the use of biodegradable plastics is an effective method. Biodegradable plastics are developed in recent years out . Degradable plastics are added to fill in the ordinary plastic material, to increase their ability to degrade the natural environment. According to the degradation of different methods, the main light -degradable materials, and biodegradable materials degradable material two kinds. However, some performance degradation material is currently inferior ordinary plastic. Additionally, some biodegradable materials without the addition of other substances conducive to recycling plastics.
