Good evening!

Can we keep our wastes in common storage bins and then give them to the contractor who will take our wastes and divide them into 5 parts (mixed paper, corrugated cardboard, glass, plastics, metals) and recycle himself. Is it possible if we have relevant documentation about sorting and recycling? 

Can our project have only 2 bins (with recyclable unsorted wastes and unrecyclable) instead of 5?
