the reason why the recycling of waste plastics is difficult
Plastic is used in our life in the face, such as food packaging, cups, water bottles, cosmetic bottles, and so on and so forth. We can see how large the amount of waste plastic is produced every day. First of all the waste plastic recycling to be cleaned, melting, drawing, granulation and other processes to become recycled plastic particles. Recycled plastic particles to be used again in accordance with the level to make a variety of products again into our lives. Plastic has a wide range of applications, the use of large, therefore, recycled plastic particles have a huge market potential and value. However, recycling of waste plastics is not an easy thing. First of all, the policy of the current recycling of waste plastics in China is mainly rely on "picking up a bottle of army" and other folk channels to complete the recycling of waste plastics. But close paragraph of time, the impact of oil prices, to recycle plastic bottles almost unprofitable, picking up the enthusiasm of the bottle army without, the recycling of plastic bottles have great influence.
This shows that the government should establish official recycling channels, so that the market can not drive the recovery of waste plastics can be used to ensure that the normal flow of waste into the factory to recycle. From the policy side, should support the regular plastic recycling enterprises, improve the recycling mechanism and standards, so that recycling of waste plastics has a clear quantitative criteria. Next is the technology of our country polyethylene foamrecycling method is mainly for the physical regeneration, recycling of waste plastics by classification, cleaning, granulation directly processing. There are a lot of ways of recycling waste plastics, in addition to physical recovery also includes energy recovery, chemical reduction and used as solid fuel. China's waste plastics processing and utilization technology is relatively low, a lot of waste plastics processing enterprises do not have the strength to introduce foreign advanced technology, but also unable to develop new technology and new technology. Finally is a waste of a variety of plastic recycling a single said waste plastics we first thought is beverage bottles or other large volume of plastic products, pet plastic bottle is occupied the absolute share of plastic bottle packaging market. But there are several kinds of waste plastics often overlooked by people, such as PE plastic bottles, acrylic, these waste plastics also has great economic value. Waste plastics recycling, or other waste recycling is in fact a global problem, but the current foreign technology or recycling system is more advanced than the domestic. China should actively introduce foreign advanced processing technology, more important is learning foreign waste recycling system, draw lessons from the advanced experience, to increase recovery and utilization of waste plastics and let the waste plastic recycling the long-standing problem is no longer difficult.
