Trash to Gas
Where some see trash, UC Davis engineering professor Ruihong Zhang sees a source of renewable energy. Zhang’s Biogas Energy Project uses silos full of bacteria to turn food scraps, yard waste and other biodegradable material into methane and hydrogen that can power homes, businesses and vehicles. One ton of waste can be turned into enough gas to power ten homes.
Zhang’s inventions have been licensed and developed for commercial application and will be used to generate clean electricity for the new UC Davis West Village, a mix of student and employee housing, retail space and a community college center.
