A-01 Distinction between wastes and by-products during the extraction and the processing stages
Aspect A-01 Distinction between wastes and by-products during the extraction and the processing stages Description Several wastes and by-products are either used or generated during the production phase of building products. A waste is an output from a process that has not yet reached the end-of-waste state. A by-product is an output that is not…
