In developing countries like Egypt the construction waste management is performed by small traders buying scraps from the contractors to resell it to factories and manufacturers for recycling. Most of these traders are illiterate and have no companies work through. They just make a deal with the contractors to pass by the project site and load specific materials. Consequently, we have no papers record the final destination of any recyclables. All what we have are the permit documents the contractors issued for these traders to allow them to get out the project site with the scraps.

My question is; as the scrap traders have no official company papers and are illiterate has no signature, is it enough to get a confirmation letter from the contractor for the waste types and quantities sold to each trader for recycling?
