Conversion of Biogas From Organic Wastes Into a High-Value Fish Food Supplement for Aquaculture in Bangladesh

We propose to develop the enabling technology and business case for use of biogas to produce a high value food supplement for aquaculture in Bangladesh. Existing anaerobic digesters will be the source of biogas. Current biogas applications give low rates of return, leading to poorly maintained systems and greenhouse gas emissions. We will repurpose biogas as a feedstock for production of a fish food supplement that prevents pathogen growth in the fish gut, decreases the need for antibiotics, increases fingerling survival, and enhances yields. Low-tech bioreactors will be developed for production of the supplement. In parallel, we will carry out a market analysis of biogas management and aquaculture practices and develop partnerships for scale-up. Ultimately, we will demonstrate production technology for the feed supplement and its use in aquaculture. SOE students will drive technology development, and GSB students will analyze the value proposition and develop the business case.
