n the work package described in this report, members are investigating whether a cooperative of farmers can become self-sufficient in energy and fertilization by using manure and organic waste flows in combination with anaerobic fermentation. The aim is to link the nutrient cycle (from manure to digestate to green fertilizer consisting of, for example, nitrate, phosphate, potassium, and trace elements) to a self-sufficient energy system, by the combined production of electricity, green gas, green fuels, and green fertilizers. Within this research such a system is called a circular multi commodity system (CMCS). In effect linking, the nutrient cycle with an energy production chain. In addition, other energy sources and sinks can also play a role in the system such as wind, solar PV and storage (e.g. batteries or hydrogen). For this symbiosis of production techniques to succeed in practice, intensive cooperation between arable farmers and dairy farmers is needed. Farmers supply part of the input from the biofermenter and receive green fertilizers at the end of the process, which are used as a substitute for fertilizer. The case is based on a cooperative of farmers with a minimal geographical spread and maximum diversity in type of business. In this way, the current waste and nutrient chain is being replaced by a more sustainable and closed cycle. This could provide significant environmental benefits: reduction of the environmental impact through the use of fertilizer, reduction of dependence on fossil raw materials, and reduction of CO2 emissions.
