| University of Washington researchers, Dr. Sally Brown and Dr. Chuck Henry, received the 2005 Green Globe Award as leaders in biosolids recycling for their design of a closed-loop recycling system.
Biosolids from King County are being used to fertilize canola plants in the Yakima Valley. After harvest, canola seeds are crushed for oil which is then converted to biodiesel.
This innovative and collaborative research project may lead to a new market for biosolids as well as a ‘home-grown’ source of biofuel. Biodiesel provides a cleaner alternative fuel to run farm equipment and biosolids transport trucks.
The award was presented during ceremonies on Earth Day at Westlake Park.
