In this context residues can include:

• agricultural, aquaculture, fisheries and forestry residues, and

• processing residues.

A processing residue is a substance that is not the end product(s) that a production process directly seeks to produce. It is not a primary aim of the production process and the process has not been deliberately modified to produce it.
