County, City & State DOC – Walla Walla, Washington
Post-consumer food and green waste
O2Compost served as compost sub-consultant to Parametrix, Inc. for the design, construction and start up of a compost facility located at the Walla Walla State Penitentiary (2003-2004). The project included facility sizing and conceptual layout, assistance with detailed design, bidding, and construction management. Following construction, O2Compost conducted on-site personnel training and follow-up process monitoring and troubleshooting services. The permit application for this project was the second to be prepared under the State’s new solid waste handling regulations.

U.S. Army Demonstration Project - Ft. Lewis, Washington

In 2006, O2Compost provided consulting services to: 1) evaluate the volume and character of various organic waste streams that are produced within the Ft. Lewis compound; and 2) demonstrate the use of aerated static pile composting as a viable method of converting these waste streams into value added products for use at Ft. Lewis. The various organic by-products included horse manure from the Ft. Lewis Equestrian Center, landscaping waste, food waste, and biosolids from their wastewater treatment plant. The plywood divider that can be seen in this photo divided two different batches (i.e. recipes) of feedstock materials for comparison purposes.
