[0002] Plastic is a high-molecular compound made from monomers through addition or condensation reactions. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Crushing is one of the technologies for solid waste pretreatment. Controlling the size and shape of solids through crushing is beneficial to the resource utilization and reduction of solid waste.
