Life Cycle Inventory & Assessment Report:Dairy Cow Slurry Biogas With Grass as an External C Source, Estonia
The Biogas Production technology uses manure and suitable co-substrates to produce energy to replace heat and electricity produced from other sources. The technology offers nutrient rich digestate for plants. The Biogas Production reduces methane emissions from outdoor storage and avoids environmental impacts by avoided heat, electricity and fertilizers. The study shows what are the environmental advantages and disadvantages of applying biogas production technology for dairy slurry co-digested with natural grass or reed canary grass compared to conventional manure management.
The environmental impacts has been evaluated along the “manure management chain” from in-house storage, outdoor storage and to application of the manure to field, by use of consequential Life Cycle Assessment (LCA).
This report on Biogas Production was prepared as part of Work Package 5 on Assessing Sustainability of Manure Technology Chains in the project Baltic Manure.
