Does anyone have experience with drying and pelletizing animal waste? What type of value as fertilizer would this have? I suppose you run it through a screw press to get the water out and then pelletize and dry? Please advise.
What chemical processes are commercially available that treat digester effluent leaving solids in a form that could be handled and sold as fertilizer? Water must leave process clean enough avoid surface water issues. Thanks, Bastean
