Basically, the most sensible thing to do is not to let plastic waste arise in the first place. For example, by doing without plastic packaging either completely or to a large extent. This is currently an illusion from a global perspective, so Deposy, as an innovative deposit system, offers a win-win situation for manufacturers, recyclers, dealers and customers. Through an innovative deposit system as well as incentives for collection for the population, the system creates purely sorted plastic waste, which enables sensible recycling. With recycled plastic, 2.5 – 4 t less CO2 emissions are produced per tonne of plastic compared to a waste incineration plant. With a plastic waste volume of 0.52 million t per year (in Germany), which is estimated to be accessible for the Deposy deposit system, the system could, according to own calculations, contribute to saving 1.3 – 2 million t of CO2.
