Recycled concrete (Source: YouTube/ERC-TECH EU) Methods of Recycling Concrete. The equipment used for crushing the concrete rubble generally consists of a rubble crusher, side discharge conveyor, screening plant and a return conveyor from the screen to the crusher inlet. The return conveyor sends back the oversized materials or the other under crushed materials which needs reprocessing.

Steel structure recovered during crushing and separation operations of concrete contribute to the carbon cycle because steel recovered from structure can be recycled. 4.
