Accepting Renewable Technologies for Waste Management Promoting Sustainable Living Among Rural Habitats

摘要

This paper elaborates on need of improvement in rural settings and its benefits after use of anaerobic digestion as renewable energy. The five villages under investigation have a human population of 12,217 and livestock of 8,141, which includes buffalo, goats, and hen. Among, livestock total waste discharged by buffalos is around 33 tonnes, goats discharge 3.5 tonnes, and hens per day discharge 400 kg of waste. Similarly, human population discharges near to 4 tonnes of excreta daily. This paper proposes a perspective for rural habitats reducing excess burden of sanitation, energy, fertilizers, and on health impacts. From the estimation of human excreta and livestock, both can generate biogas of 2060 m~3 daily using renewable techniques. Similarly, accepting improved sanitation may reduce the risk of human health after excretion and emission of air pollutant, lowering premature deaths. Practicing anaerobic digestion, accounts to fulfill fertilizer requirement of N, P and K of approximately 74 ha of land per year. Furthermore, air pollutants such as carbon monoxide (CO), sulfur dioxide (SO_2), oxides of nitrogen (NO_x), carbon dioxide (CO_2), methane (CH_4), and particulate matter (PM2.5 and PM10) could reduce to a greater extent. Biogas a renewable form can gain additional carbon credits to the rural community. Paper tries to present an overall positive viewpoint of such study in rural habitats of developing countries.
