Organic Waste to Resources Research and Pilot Project Report: Producing Energy and Fertilizer from Organic Municipal Solid Waste: Enhancing Hydrolysis and Bacterial Populations and Mixing and Thermodynamic Modeling of New Solid Waste Treatment Technology

Usama Zaher, Shulin Chen, Chenlin Li, Liang Yu, and Timothy Ewing, June 2009. This project developed, tested and modeled a high solids anaerobic digester consisting of a solids reactor and a leached liquids UASB for reacting volatile fatty acids. At near neutral pH the system improves methane production 50% over existing digesters, while return flow reseeds the solids digester with high titer micro-organisms that improved biological kinetics. The dual reactors system provides for control of digester limiting acid and ammonia processes, while allowing for nutrient recovery, and significantly improves performance for capital outlay.

Organic Waste to Resources Research and Pilot Project Report: Waste to Fuels Technology: Evaluating Three Technology Options and the Economics for Converting Biomass to Fuels

Hayk Khachatryan, Ken Casavant, and Eric Jessup, Jie Chen, Shulin Chen, and Craig Frear, September 2009. This study further investigated biomass from the 2005 biomass inventory by comparing three fuel technologies: cellulosic biomass conversion by fermentation for ethanol, or gasification for mixed-alcohols, and anaerobic digestion of high volatile solids biomass for methane production. The study then integrated the major cost factors: biomass availability, feedstock prices, transportation costs, processing costs, and geographic distribution into a comprehensive model framework using GIS and MATLAB-SIMULINK models, to assess final delivered fuel cost.

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.
