Abstract
Anaerobic digestion was analyzed as the biological process that converts the organic matter present in various types of wastes,
activated sludge from the wastewater treatment facilities respectively, into biogas. Latest advancements in the mathematical
modeling, simulation and control practices have helped in gaining a better insight of the process. In this paper, an energy
efficiency and techno-economical investigation of anaerobic digestion technology for the CHP cogeneration unit, has been done
to detect maximum concentrations of methane and to minimize the costs at a Municipal Wastewater Treatment Plant.
