Most, but not all, recovery and reuse is ‘informal’ and long-standing, or ‘customary.’
(Fertilizer and feed production are carried out by the corporate sector as well). The
quantities of wastes involved and the costs and benefits of reuse practices cannot be
estimated at the present level of knowledge. The informal and undocumented nature
of most practices poses problems for ensuring safe and sustainable waste reuse.
