Douglas County Greenworks serves 7,500 customers as biochar plant remains under construction

Douglas County’s Greenworks site has served more than 7,500 customers since opening in April, while the county’s planned biochar facility remains under construction, with equipment delivery scheduled for Sept. 21 and commissioning planned for February 2027.

The slash-and-mulch program accounted for nearly 5,000 customers and about 15,000 cubic yards of material, according to the Aug. 11 Board of County Commissioners meeting. The electronic-waste program, which began July 6, had served nearly 1,000 customers and collected 75,000 pounds. A household hazardous-waste program launched the previous week had served 125 customers.

The biochar facility is planned at 5675 Delva Way in Sedalia, next to Core Electric and the Sedalia Landfill, according to Douglas County’s project information. The county says it is intended to process woody material from wildfire-mitigation and forest-restoration projects and support other waste-diversion services.

Public Works staff told commissioners that equipment is expected to arrive Sept. 21, after which much of the building will be constructed around it. As of Aug. 11, the facility had not begun operations.

A Denver Post report described the facility’s planned capacity as about 10,000 tons of woody material per year. That is a projection, not a measured result.

The available records do not quantify wildfire fuel removed, waste diverted from landfills or water conserved by the biochar facility. During the commissioners’ discussion, one commissioner cited a potential 37% reduction in water use associated with biochar and said golf courses had seen reduced use after applying it. The meeting record provided no study, baseline or measurement period and did not tie the figure to Douglas County’s facility, so it remains an attributed claim rather than a verified local outcome.

Future benchmarks will include equipment delivery, commissioning and the county’s publication of operating data on feedstock processed, landfill diversion and water effects.
