Bio Plant System in Urban Area: An Ideal Model

Abstract

Bangladesh is an energy-starved country. Despite its large reservoir of natural gas, demand in the sectors like households and industries is too high to fulfill. Waste management in big cities also becomes a critical problem as more and more people are migrating to urban areas. Biogas can be a promising solution for both the energy crisis and waste management for countries like Bangladesh because of its simplicity, price, and efficiency. But the establishment of bio-plants in an urban area is not so common due to the lack of space, risk of leakage, and social taboos. This study represents an ideal urban system with an integral waste management and biogas production plant to evaluate system feasibility based on the economic benefits and associated risks from energy production. A modern bio-plant arrangement has been proposed for an ideal urban locality having 50 buildings with 10 families each. This study shows that gas usage of such an ideal locality can be fulfilled from the proposed bio plant system by up to 35% of the per day demand. Although the model requires some modification for its real field implementation, this study can pave the way for further research in this arena.
