Waste disposal is an emerging problem in almost all urban areas of Bangladesh. The magnitude of the problem is relatively small and manageable in rural areas. Improper management and casual dumping of waste is a noticeable cause of ruin of the environment in most cities. It appears to be a growing concern in recent times. Low collection coverage, unavailable logistic services, and lack of suitable treatment, recycling and disposal facilities are responsible for substandard waste management, leading to water, land and air pollution, and for putting people and the environment at risk. Rapid population growth has made waste management a serious problem today. Narayanganj, just outskirt of Dhaka city, is not an exception regarding poor waste management. The scattered and uncollected waste creates public nuisance, clogs sewers and open drains, encroaches roadways, diminishes aesthetic appearance and causes unpleasant odor. Waste is collected from dustbin or secondary transfer station transported to the dumping sites. At this moment conscious authorities as well as stakeholders are concerned to make sure the proper management of waste and utilize it in production of electricity.
GIZ, the German Development Cooperation Agency, had been requested at the beginning of 2015 by Sustainable and Renewable Energy Development Authority (SREDA) to conduct a detail feasibility study to identify prospective energy solutions from waste in Keraniganj. International Experts appointed by GIZ conducted the study for six months in collaboration with SREDA officials, local government officials and public representatives from Keraniganj. Two (2) stakeholder consultation workshops were held during the feasibility study. On 12 August 2015, the final report of the Feasibility Study was submitted to Mr. Nasrul Hamid MP, Honorable State Minister, Ministry of Power, Energy and Mineral Resources. The Experts recommended Dry Fermentation (Anaerobic Digestion) technology for Keraniganj Waste to Energy Project as the nature of the municipal waste (household waste, markets or commercial waste, Agro-industrial Waste, Medical Waste and so on) generated in Keraniganj are mostly organic. Biogas from anaerobic digestion process could generate electricity as well as heat. The condensate from biogas could be used for composting. Wastes from Keraniganj garments and residual waste from composting are recommended to be used to produce RDF (Reduced Derive Fuel) as a fuel option in Fixed Chimney Brick Kilns. Depending on suitable waste management plan in place, about 4-5 MW capacity electricity generating plant could be installed in Keraniganj.
Power Division has assigned Bangladesh Power Development Board (BPDB) to implement the Waste to Energy Generation Plant on pilot basis. The project will be set up in BPDB’s owned land in Keraniganj. The capacity of the combined heat and power unit will be 1 MW (430 kW Electricity + 480 kW Heat)
