The processing parameters in mechanical recycling significantly affect the final properties of the recycled plastic. First, the sorting and cleaning processes influence the purity of the recycled material. Inadequate sorting can lead to contamination with different types of plastics, while insufficient cleaning can leave residual contaminants that degrade the final product's properties. Second, the grinding process affects the particle size and shape of the recycled plastic. Excessive grinding can generate fine particles that are difficult to process and can reduce the mec....
