keepin stands for the development of an understandable disposal system that tries to see waste as a raw material and to keep it in the economic cycle. It is aimed both at disposal companies and at the population, who reduce the effective processing of materials by incorrect separation. The keepin application enables the user to compare and understand his own waste quantities and costs. It offers assistance in sorting and can provide information about the processing of materials. Waste disposal is generally integrated more concretely into everyday life and achieves a deeper examination of one's own waste behaviour. The user can reflect his personal consumption and actively influence the values.
