Can plastics be refined?

Plastics (including waste plastics) can be refined.

Waste plastics mainly refer to the leftovers in the plastic processing process and the broken materials after the recycling of waste plastic products. China is the second largest producer of plastic products in the world, producing countless waste plastics. A large number of waste plastics are difficult to decompose in the natural environment, causing serious white pollution and destroying the ecological environment. Therefore, in recent years, waste plastics have attracted the attention of scholars. The traditional methods of plastic recycling are mainly regeneration and reuse according to the mechanism; Burning to recover heat energy; Preparation of fuel oil by catalytic cracking. At the Beijing International Energy Conservation and Environmental Protection Exhibition in May, 20 12, an expert put forward a plastic waste treatment project: white plastic waste will be "transformed" into refined oil after three stages of pretreatment, cracking and refining, which can be used for domestic and industrial production. It is reported that waste plastic oil can be used in direct injection diesel engines.
