Abstract

Bangladesh is in the midst of a severe and worsening energy crisis. The continuous depletion of fossil fuels is sticking the concern into the search for new energy sources which are renewable as well as sustainable. Among the renewable energy sources, biogas from the poultry and dairy industries is an increasingly growing and promising sector. A survey was conducted to understand the present status of biogas technology in Bangladesh. Data were collected by interviewing farm owners and major stakeholders. The problems and barriers to the implementation and dissemination of biogas plants in Bangladesh were also identified through SWOT analysis. A total of sixteen farms were selected to collect data regarding current operational conditions. The economic viability was also evaluated. Most of the selected farms were found to be under-fed in spite of having huge potential. Though the H2S concentration of biogas produced from different plants was high, most of them had no purification unit. The results of the economic analysis showed that the biogas plants operating in Bangladesh are at a loss as currently no subsidies are provided. The outcome of the SWOT analysis identified high initial investment, lack of technical knowledge, lack of local technology, poor management, and proper bio-slurry handling technology as the main barriers to disseminating biogas technology in Bangladesh.
