Life Cycle Assessment and Techno-Economic Assessment of Anaerobic Co-Digestion: A Short Review

Waste-to-energy conversion such as anaerobic digestion has been widely promoted under the subsidies to decouple from fossil fuel dependence system and its inherent two-fold benefits. It could diversify the renewable energy matrix and divert the waste from the landfill. Co-digestion of two and more f...
