Anaerobic digestion of different agricultural wastes: A techno-economic assessment.

•Techno-economic analysis of multiple feedstocks for AD with biogas upgrading pathways.•SS-AD of ternary mixture benefited the digestate price and make SS-AD profitable.•SS-AD of binary mixture under bio-methane pathway was not financially attractive.•The introduction of a CHP unit highly improved the economics of SS-AD.•Production price and labor cost have the highest impact on the NPV value.
