Bad odours – this is an issue many recyclers of post-consumer plastic scrap have to deal with. The input material they are processing often contains migrated substances from food, cosmetics or cleaners, which cause an unpleasant smell during the recycling process. But also residues of monomers, oxidation or hydrolysis, as well as decomposition products (VOCs – volatile organic compounds) can be the reason for unwanted smells in recycled granulate. Solid contaminants and foreign matter, e.g. paper or wood, cannot be removed to 100 % even in intense washing processes and thus can cause odour development in the extrusion process.
