Biochar (Pyrolysis)

WSU Thermo-Chemical Engineering Laboratory: Manuel Garcia-Perez

Professor Garcia-Perez is an expert in thermo-chemical engineering of biomass into energy and products. Our work with Garcia-Perez includes the development and evaluation of biochar from the pyrolysis of woody organic wastes as a potential soil amendment.

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 […]

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 […]

Organic Waste to Resources Research and Pilot Project Report: The Next Step for Biomass Energy Development in Clallam County

Northwest Sustainable Energy for Economic Development, Institute forWashington′s Future, and Northwest Cooperative Development Center, September 2009. New technologies allow us to harness the energy in animal and plant biomass to generate electricity and fuel vehicles. The energy derived biomass resources that are produced and harvested sustainably is considered renewable. This report is a primer on […]

The Formation of Polyaromatic Hydrocarbons and Dioxins During Pyrolysis: A Review of the Literature with Descriptions of Biomass Composition, Fast Pyrolysis Technologies and Thermochemical Reactions

Manuel Garcia-Perez, June 2008. It is clear that any new thermochemical processing technologies must represent clean processes. To examine whether the production of bio-oils and biochar could generate PAH and dioxins during pyrolysis processes, a global literature review was conducted. Processing method for recovering energy, fuel and products from organic waste can have detrimental impacts […]
