Recycled steel from concrete recycling, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Included processes: One of the resultant products of the the 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 allocated unit process for use in recycled aggregate.
