Organic Waste to Resources Research and Pilot Project Report: Converting Washington Lignocellulosic Rich Urban Waste to Ethanol

Rick Gustafson, Renata Bura, Joyce Cooper, Ryan McMahon, Elliott Schmitt, and Azra Vajzovic, September 2009. This study investigated the potential of producing ethanol from three primary sources: mixed waste paper, yard trimmings, and a laboratory prepared mixture (50/50 food & paper) representing MSW. Pretreatment consisted of dilute acid hydrolysis (mixed paper and MSW), and steam explosion (yard waste). Ethanol yields of 105, 90 and 55 gal/ton were found for the MSW, mixed paper, and yard waste. A preliminary Life Cycle Assessment showed that overall environmental impacts of ethanol production from MSW are highly beneficial compared to landfill. Conversion of the MSW mixture to ethanol was found to be economically viable.

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: Use of Biochar from the Pyrolysis of Waste Organic Material as a Soil Amendment

David Granatstein, Chad Kruger, Hal Collins, Manuel Garcia-Perez, and Jonathan Yoder, September 2009. Biochars from different feedstocks were tested on five soils. Biochars on all soil types increased soil C. Biochar C was stable in soil with mean residence times estimated in the hundreds of years. Soil nitrate levels were reduced with increasing biochar rate perhaps due to ammonium adsorption. Biochar did not accelerate loss of indigenous organic matter through the ‘priming effect.′ Biochars raised soil pH, but did not lead to consistent plant growth improvements.

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.

Organic Waste to Resources Research and Pilot Project Report: New Biorefinery Concept to Convert Softwood Bark to Transportation Fuels Final Report to the Washington State Department of Ecology

Manuel Garcia-Perez, Shulin Chen, Shuai Zhou,Zhouhong Wang, Jieni Lian, Robert Lee Johnson, Shi-Shen Liaw and Oisik Das, September 2009. This project tested a new pretreatment concept to enhance the production of sugars from the fast pyrolysis of wood and straw. It proved that sugars recovered from pyrolysis can be easily converted into ethanol. These two results are important because they show that fast pyrolysis of wood or straw followed by bio-oil hydro-treatment can create green gasoline and diesel (from lignin), as well as ethanol (from cellulose).

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.

2008 Estimated Costs and Returns for a 150-head Cow-calf to Grass-finished Beef Production System in the Channelled Scablands Range Area of East-central Washington

In response to the popularity of grass-finished beef, this publication provides a production budget analysis using both ranch-owned and leased forage sources in eastern Washington to determine profitability. Funded by the William D. Ruckelshaus Center, the Beefing Up the Palouse pilot project applied a total systems approach to develop a replicable production model to help producers take full advantage of the eastern Washington dryland wheat production area resource base.
