A novel small-medium industrial bioenergy project is investigated in-terms of its socio-economic and environmental sustainability. This research project exclusively features multi AD system induced with motorized stirring, methane purification, compression and storage systems. The productivity and success of the plant has been proven on a variety of substrates in the form of cow-buffalo manure and potato-vegetable wastes etc. This article sums-up the sustainability analytics of this modernized plant as; daily average energy productivity of 384kWh and rate of return is 15.42% per year. 45.3% of the socio-industrial community shown the willingness to invest is such project; as such the industrial and employment growth can be up-to 55%. The life-cycle environmental analysis deliberated that the corresponding climate change potential in-terms of equivalent amount of CO2 is 113.5kg on average for cow-manure and mix of it with potato slurries.
