Recycling brick rubble and concrete, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes: Coproducing process of recycling concrete to aggregate and steel. Remark: End of Waste Stage considered to be at concrete recycling plant. Therefore no transport to recycling plant is included. This in an unallocated unit process. Do not use it directly but link to the allocated process of recycled aggregate or steel scrap, from concrete recycling.
