Machines and technology are not the key players in our industrialised world. Humans take centre stage and achieve progress with their knowledge, experience and skill.
There are limits to the use of olfactorily contaminated plastics for the production of fresh materials. Odorous contamination of them needs to be minimised so that they are suitable for manufacturing new plastic products. A combination of analytical and sensor technology can help to identify olfactory contaminants and to check the efficiency and effectiveness of cleaning processes.
