The term "resource" refers to a general term for various material elements such as physical resources, financial resources, and human resources owned by a country or a certain region. It is divided into two categories of natural resources and social resources. The former is sunlight, air, water, land, forest, grassland, animal, mineral deposit, etc.; the latter includes human resources, information resources, and various material wealth created through labor. The environmental technology refers to production equipment, production methods and procedures, product design, product delivery methods, and the like, which can save or protect energy and natural resources, reduce environmental loads generated by human activities, and thus protect the environment. Environmental technologies include not only hard technologies such as pollution control equipment, environmental monitoring instruments, and clean production technologies; soft technologies such as waste management and those intended to protect the environment, work and activities, etc. are also included. The traditional waste plastic treatment methods comprise a composting method, a landfill method and a burning method, which all seriously affect the recycling of plastic resources, and the treatment methods not only block the way of plastic circulation, but also generate dioxin and other highly toxic substances after burning, thereby causing secondary pollution.
