Material Recovery Facilities for Municipal Solid Waste

Air Classifier Air classification employs an air stream to separate a light fraction (e.g., paper and plastic) from a heavy fraction (e.g., metals and glass) in a waste stream. Variables other than density, such as particle size, surface area, and drag, also affect the process of material separation through air classification.
