The initiators developed a process in which spent mushroom compost from mushroom cultivation is upgraded and turned into a valuable soil improver. They do this by biologically drying spent mushroom compost in so-called tunnels. By adding a small amount of concentrated manure, a popular soil improver rich in nitrogen, phosphate and potassium is created. The spent mushroom compost is not only upgraded to a popular soil improver but it is also made lighter in specific weight. As a result, fewer freight transports are needed to deliver the product. A large amount of heat is released naturally during the biological drying process. This heat is used to provide the neighbouring existing mushroom nurseries with heat and consequently natural gas-fuelled boilers are no longer required. The surplus heat is distributed to nearby crop growers.
