Abstract

Paper presents design process of the prototype line, dedicated for production of fertilizer pellets from digestate-ash mixture. For enrichment of the nutritional characteristics of the final product additives were also used, like urea, elemental sulphur or phosphorite, and special fungal strains from Trichoderma spieces. During this process raw material will be dried (raw digestated), mixed, granulated and packed in one technological line. Presented concept, shows that there is possible to produce high quality fertilizer, from waste materials derrived form Green energy production, what should be one of very interesting ways to develop digestate and ash from biomass combustion.
