Producing energy (power, heat, and fuels) and products (i.e. chemicals, nutrients, fiber) from biomass has become a relatively controversial issue. What is lost in that controversy is that bioenergy and bioproducts can help improve the sustainability of our agriculture, food systems and rural communities through diversification (economic and biological); recovery and recycling of carbon; recovery of nutrients and energy from organic wastes; reduction of environmental pollutants; and generation of income and investment opportunities for farmers and rural communities.
The Pacific Northwest is rich in it’s biological diversity — both in natural systems and agricultural systems — which provides a valuable resource base for developing sustainable, scale-appropriate technologies and products that reduce environmental pollution, produce renewable energy and products – many of which can be recycled into agricultural production, and generate income for rural communities. CSANR has helped to develop a significant research capacity in bioenergy and bioproducts — especially focusing on recovery and recycling of organic waste materials for sustainable end uses in agriculture.

Three oilseed crop production workshops were held the last week of January 2011 at Okanogan, Reardan and Colfax, Washington. Presenters included regional producers, university researchers, agency personnel, and industry representatives. Attendance surpassed 250 during the three days, indicating a renewed interest in utilizing oilseed crops for rotation benefits, potential economic advantages, high quality meal for livestock, and ‘home-grown’ biodiesel.
This is a 6-state effort supported jointly by the State Energy Offices and the US Department of Energy that provides a clearinghouse for information on bioenergy in the region. It is the repository for a number of research reports and tools developed by CSANR and our colleagues.
Pacific Northwest cropping systems are dominated by irrigated specialty crops (ie. fruits and vegetables), high quality forages, and a dryland cereal grain system (primarily wheat). It is highly unlikely that we will ever seen the fence-row to fence-row production of commodity crops that fit the model of first generation biofuel crops (ie. corn and soybeans). However, a number of interesting alternative crops that could be used for first or second generation biofuels / bioproducts could prove to be interesting options that enable farmers to manage their current cropping systems more sustainably. For instance, the brassica crops (canola, mustard, camelina, etc.) are a valuable rotational crop for wheat by providing biological and management tools that enable producers to break up weed and disease cycles that affect wheat production. Some of the high-biomass producing grasses could provide tools to both dryland and irrigated producers to restore degraded soils. A long-term biofuels croppping systems research project to develop and evaluate the use of biofuel crops in Washington cropping systems (statewide) was established in 2007.
This report is a comprehensive response to 2007 Washington State legislation (HB 1303) that tasked Washington State University to 1) analyze the types and corresponding amounts of biofuel in the state and 2) recommend viable incentive programs to promote biofuel market development. Inside you will find policy recommendations based on analysis of a broad set of policy options, including renewable fuel standards and subsidies, carbon taxes, as well as approaches to support research, implementation of new technologies, and creation of infrastructure.

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.
