Organic Waste to Resources and Pilot Project Report: Biodiesel and Biohydrogen Co-Production with Treatment of High Solid Food Waste
Yubin Zheng, Jingwei Ma, Zhanyou Chi, and Shulin Chen, September 2009. two-step process was developed as a potential technology to produce hydrogen and biodiesel from food waste. The first process use fermentative bacteria to breakdown glucose from food waste to produce hydrogen and volatile fatty acids (VFA). The VFA are then fed to yeast for simultaneous carbon sequestration resulting in production of biodiesel from the oil-producing microbial biomass.
