Therefore, after mechanical sorting or enrichment (improving the quality and content of plastics) is carried out on waste plastics in the household garbage, high-temperature isolated air cracking is carried out, and the preparation of fuel oil and fuel gas is an important means for realizing plastic recycling and is also an important recycling link in the current comprehensive garbage treatment process, so that the comprehensive garbage treatment process is widely focused.
The light garbage refers to oversize products, mainly plastics, fabrics and the like, of landfill garbage after excavation and screening treatment.
