WebRecovering chemicals and fuel from plastic waste streams is nothing new. Processes including pyrolysis and gasification, which break down plastics using high temperatures and catalytic processes, can recover useful materials. However, these approaches create several products, including waste, and require additional processing and purification. WebAlternatively the FPP may be multilayer and separate with 3-dimensional plastic types. Often the thin plas tic film is too small or too large to be accurately detected. Furthermore, most types of sorting equipment are unable to adequately distinguish material types when they have highly glossy, dark colored surfaces, paints and coatings.
