Abstract
Abstract Bogura is the largest municipality in Bangladesh by population. Its huge population and agri-industry produces a great deal of solid, faecal and industrial waste which has been a matter of concern for the municipality. IRC started working for a solution and completed a pre-feasibility and feasibility study to find innovative technologies and an operation model. The feasibility study has produced an integrated solution of faecal sludge, municipal solid waste, agri-waste and aerosol can recycling model which also helps to reduce surface and ground water contamination. The solution integrates conventional anaerobic digestion with new torrefaction and aerosol-propellant capture technologies which treats the municipality solid waste and aerosol cans to produce biofuel and liquid petroleum gas, respectively.
Highlights
The feasibility study team developed a methodology considering two issues as the backbone (Arikan & ÖzalpVayvay ): environmental and financial sustainability. It tried to work out the magnitude of the waste management problem
Desk research was carried out on the available regulations and technologies. It identified the complex and interlinked system working for WASH and waste management in the municipality and tried to track the status of the components of the system (Huston & Moriarty )
It has the potential of scale-up in different cities. This model provides a zero waste solution of waste management for a city. It started with the idea of addressing the water and waste management problems of the town and expanded to overall improvement of the environment
Summary
With rapid industrialization and urbanization, the influx of migration from the villages towards the towns and cities has increased significantly. Industrial progress in cities and towns has led to an extra population load (Khan ). This has resulted in unplanned urbanization which leads to the generation of huge amounts of waste. The cities and towns are not capable of processing/treating these extra wastes. It is the largest municipality town in Bangladesh with a population of 0.6 million. It is situated in the north-western part of Bangladesh.
