Recycled aggregate, at plant {AU}| | AusLCI, U
Unit process Australia v00.00.001
Remark: One of the resultant products of the the coproducing process of recycling concrete to aggregate and steel. 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.
