Biomass-powered combined power, cooling, and cooking system (CPCC) is a novel approach towards the green energy tri-generation system which offers an alternative solution to the use of fast-depleting fossil fuels and harmful carbon emissions into the environment. This system consists of a downdraft biomass gasifier a thermochemical conversion unit, an internal combustion (IC) engine for generating green electricity, a refrigeration cooling system for storing perishable items, and a commercial burner for community cooking applications. This research article investigates the theoretical performance of a proposed CPCC system integrated with three comparative units of vapor absorption, adsorption, and compression refrigeration systems. From the findings of the energy and carbon dioxide mitigation potential analysis, adsorption-integrated CPCC system suits as the best operating unit in pollution-free hilly regions. Besides, a sustainability approach is performed using energy, emergy, life cycle assessment, and techno-economic analysis tools for the capacities of 20 kW of electricity generation, 12.5 kW for refrigeration cooling (~ 3.5 TR), and 10 kW of the cooking burner based on their energy demands in the targeted region. With all these considerations the best-opted adsorption-integrated CPCC system resulted with 66.73% efficiency, 5712.263 MT yr−1 of carbon dioxide emission, 5.85 years of payback period, and lower emissions in emergy analysis and life cycle assessments, respectively.
