HoSt built a co-digestion installation in Herk-de-stad (Belgium). Unique about this system is that the vegetable and animal material is digested and drained in seperate lines.
The vegetable line consists of a digester and after-digester. The material from the after-digester is separated into a solid and liquid fraction. The solid fraction is fed to the animal digester and then thickened together with the animal material. The concentrator uses heat from the CHP to reduce the volume of the digestate. The liquid fraction is used as a fertilizer material for agriculture.
