POSSIBILITIES OF USING BY-PRODUCTS IN THE CIRCULAR PRODUCTION PROCESS IN BIOGAS POWER PLANTS
Abstract:
A biogas power plant uses biomass (manure, silage) to produce biogas for energy conversion to electricity and heat and digestate as byproduct of the anaerobic digestion process. The production of first generation agro-energy crops, as basic raw materials for silage, should be organized on marginal land. The application of solid digestate on such land should enable an increase in yield of agro-energy crops, avoiding the use of mineral fertilizers. By applying this concept, advantages are achieved for the management of the biogas power plant through the reduction of operating costs (economic advantages): mineral fertilizer is substituted by a by-product from own production, a production chain is established on the nearest land; environmental significance (environmental benefits): reduced greenhouse gas emissions into the atmosphere; improving the production capacity of degraded land; and general social (social advantages): mitigation of climate change using renewable energy sources - biomass and improvement of production capacities (valorization) of degraded lands.
