Manure Benefits: Energy and GHG Emissions

This lecture by Gillianne Bowman explores the energy and greenhouse gas emissions benefits of converting manure to biogas through anaerobic digestion. It assesses the biogas potentials and GHG emissions benefits in Switzerland, considering the spatial distribution of manure, specific composition, and methane yield. The lecture also covers the potential biogas production at farm level, lab measurements of manure composition and methane yield, estimation of biogas potentials, GHG emissions calculations, different scenarios for manure treatment, and the results obtained. It concludes with the potential of animal manure to generate energy and reduce GHG emissions, proposing strategies to increase its utilization in Switzerland.
