Classification of the commodity as either waste, or secondary raw material is decided by their other use, hence the possibility of their further profitable processing.
Using the commodity exchange as an institution with strong governing conditions and state conditions for trading with waste, also arises from Act No. 185/2001 Coll., on waste. Specifically in Principle II concerning Obligations, Part 1, section 16 of this law states that the waste generator is obligated to transfer the waste only into the ownership authorised to accept it as pursuant to section 12, par. 3, and either directly, or using an authorised legal entity for it (the Commodity Exchange is stated as an example of such a legal entity).
