This paper discusses the main findings of research conducted by Caleb on the potential of CDM for the commercialization of the small- to large- scale Integrated Biogas System (IBS). IBS utilizes a system approach for the efficient management and conversion of agro-industrial waste into clean biogas and organic fertilizer. The methane captured could either be used for electricity generation in large/medium commercial enterprise or used for cooking, lighting and heating hot water in small scale community.
