Extracting valuable energy, carbon and nutrient resources from organic waste

WSU scientists have conducted extensive research on Anaerobic Digestion (AD) as a technology for recovery of methane (energy), stable carbon, and nutrients from organic wastes such as manure, food processing wastes and the organic fraction of municipal solid wastes (OFMSW). Our research has evaluated the technical and economic performance of commercially available systems, developed improved AD reactors, and commercialized WSU patented nutrient recovery technology. This webinar, presented by CSANR director Chad Kruger and CSANR scientist Craig Frear, will provide an update on the latest results from the WSU Climate Friendly Farming Project’s AD research.

The Second Solution: Agriculture’s Role – video featuring eastern Washington farmer John Aeschliman

The Northwest Biocarbon Initiative aims to galvanize farmers, foresters, community leaders, and thinkers to demonstrate the essential role that natural systems can play in ensuring long-term climate stability. The Center for Sustaining Agriculture and Natural Resources is part of this collaboration with several of the Northwest’s leading conservation organizations who see this effort as a logical extension of our region’s rich natural resource heritage and our history of groundbreaking innovation and stewardship.

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.
