Biological Conversion of Biogas into Carbon-Neutral Environmentally-Friendly Material

Water, energy, materials, and food are essential for human well-being, poverty reduction, and sustainable development. Viable steps need to be taken to renew our increasingly scarce essential resources. One option is to recover these valuable resources (water, energy, materials, fertilizers, food, etc.) from waste. This research presents recent innovations to transform waste treatment infrastructure into resource recovery centers by converting organic waste into biogas methane and using methanotrophic bacteria to convert biogas methane into value-added products. Methanotrophic bacteria can produce biodegradable bioplastic, polyhydroxyalkanoates (PHAs), a sustainable alternative to petroleum-based plastics that can sequester carbon and help address climate change. Methanotrophs can also produce prebiotic fish/animal foods that improve fish/animal health and enhance growth. Altogether, use of methanotrophic bacteria in waste treatment infrastructure enables production of valuable bioproducts.
