In the recycling sector, compressed air is employed at multiple stages, from sorting to processing.
-
Material sorting
In automated sorting systems, compressed air transports and separates waste. Air flows can separate light materials, such as plastics and paper, from heavier items like metal and glass.
-
Cleaning and preparation
Compressed air removes dust, dirt and other contaminants from hazardous materials and waste before processing.
-
Crushing and grinding
Specialised pneumatic crushers and grinders use compressed air to efficiently process waste.
This reduces electrical energy requirements and improves the quality of recycled materials.
