The enthusiast must consider that the success of the project is really based on a successful integration of simple components (door-to-door, separation in many streams, digitalisation of the supply chain, advanced logistics) to a zerowaste business model. This integration was prepared for many months with field operations and communications with each and every household. In addition, this integration is supported or even better shaped by the digitalisation of the whole system. And exactly those two crucial aspects are difficult to be implemented by municipalities that are trapped in lack of resources and caged…
