Accounting for roughly 25-30% wastage attributed to each slaughter; presently, India generates about 22-25 lakh tons of slaughterhouse waste (SHW) every annum, while municipal solid waste (MSW) has already stretched to a peak value of 53.88 million tons per annum. With few technical interventions, landfilling and deep burial are the primary means of handling and disposing of the wastes in most suburbs. So far, various biochemical, physical, and thermal treatment alternatives have been extensively researched and practised at pilot scales to manage SHW and MSW. However, further scale-up of such treatment technologies was infeasible due to the concerns such as poor efficacy, high vulnerability, and high capital and administrative support requirement. The SHW and MSW are utterly dissimilar in terms of their characteristics due to their generation and composition sources. Given the biochemical and physiological characteristics, different treatment techniques like biomethanation, co-digestion, co-composting, and landfilling have been considered for comparative analysis of the efficiencies in the treatment of MSW and SHW. However, some challenges are associated with each of these technologies, including an elevated level of fat and protein with the presence of long-chain fatty acids in SHW, which poses a threat to biomethanation. In MSW, excessive lignocellulosic components hinder the bioprocess. Hence, this study focuses on various technologies available for SHW and MSW treatment and identifies the best technology using the analytical hierarchy process (AHP) tool.
