Struvite as a Phosphorus Fertilizer Source for Greenhouse Crop Production – webinar

This webinar highlights recent research by Rita Hummel of WSU on struvite as a phosphorus source for greenhouse production of bedding plants and vegetable starts. Her research includes struvite derived from municipal wastewater and dairy manure. Craig Cogger opened the webinar with a brief overview of the phosphorus challenge. After Rita’s presentation of greenhouse research results, Keith Bowers discussed struvite production as one phosphorus removal technology for wastewater at livestock, food processing, and public sewage treatment sites. The webinar closed with a brief summary by Craig and an open question period.

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.

Overview of Biomass Pyrolysis Technologies – Historical developments and potential for the production of bio-char, advances fuels and high value chemicals

Recorded webinar (online presentation) from June 1st, 2011 by Manuel Garcia-Perez, PhD; Assistant Professor, Biological Systems Engineering. The reactors used for biomass pyrolysis can be classified into slow and fast pyrolysis. While slow pyrolysis reactors are mainly used to produce charcoal, fast pyrolysis is the technology of choice to maximize bio-oil yields. Yields as high as 80 wt can be obtained with this technology. During the webinar historical developments and potential of pyrolysis technologies for the production of bio-char, advanced fuels and high value chemicals are discussed.
