Rajshahi:Biogas is gaining traction as an affordable alternative to liquefied petroleum gas (LPG) in the Rajshahi region, particularly among rural communities. The increase in biogas usage is driven by rising LPG prices and fuel shortages, prompting residents to search for more sustainable options for cooking.
According to Bangladesh Sangbad Sangstha, the Rajshahi Department of Youth Development has reported a steady increase in the installation of biogas plants over recent years. Starting with 7 plants in the 2022-23 fiscal year, the number grew to 50 in 2023-24, 58 in 2024-25, and 113 in 2025-26, with an additional 12 plants installed as of August in the current fiscal year. The total number of biogas plants now stands at 240, producing more than 32,000 cubic feet of gas daily and approximately 1,824 kg of organic fertilizer.
Residents, such as Jasmin Khatun from Nowhata Municipality in Paba Upazila, have experienced the benefits firsthand. Jasmin noted that the biogas plant reduced her cooking costs and effectively utilized livestock waste. She explained that the high cost of LPG and the availability of cattle dung led her to install a biogas plant, which now serves as her primary cooking fuel source. The plant's residue is used in her vermicompost farm to further support her agricultural activities.
Despite the benefits, the initial installation cost of biogas plants remains a significant barrier for many families. Jasmin suggested that government financial assistance could enable more households to adopt biogas technology, which could support one or two families per plant.
In addition to residential applications, researchers have developed a model to supply electricity to 500 electric three-wheelers and produce hydrogen for 100 hydrogen-powered vehicles, proposing the use of municipal waste as a raw material for biogas production. This model demonstrates the potential for meeting the city's entire energy demand from renewable sources.
Shariful Islam, Deputy Director of the Rajshahi Department of Youth Development, emphasized efforts to promote biogas usage across various upazilas to reduce fuel costs and provide agricultural benefits. Dr. M Habibur Rahman, a zoology professor at the University of Rajshahi, highlighted biogas as an environmentally friendly alternative that reduces reliance on conventional fuels, urging the government to expand its use.
