Biomethane through resource circularity: Research, Technology and Practices is an invaluable resource for researchers, policy makers, implementers and PhD and Marsters level students in universities analyzing the present status, waste biomass including agro wastes, success in experimentation & commercial production, future needs and other relevant areas. While huge biomass is wasted by open burning, there is potential of energy generation that can be extracted from the biomass preventing GHG emission and creating business opportunities. Abundance and renewable bioenergy can contribute to a more secure, sustainable, and economically sound future through biomethanation process by selecting followings: Supply chain sustainability of clean energy sources Appropriate Anaerobic Digestion technology with different feedstock Processes Parameter Optimization and best fit conditions, Productivity, Purification of biogas and end use Economic feasibility as business case, Commercialization, generating employment and Revitalizing rural economies This book addresses most of the above issues in lucid manner by experts in the field from different countries which are helpful for the related stakeholders edited by experts in the field.
