Douglas County Plans Nation's First County‑Operated Biochar Facility Near Sedalia

Douglas County Public Works is moving ahead with plans for what county officials call the nation’s first county-operated biochar facility on an industrial parcel near Sedalia off U.S. Highway 85, a project budgeted at $8,000,000 and designed to process about 10,000 tons per year of downed trees and woody waste.

County materials describe the plant’s core mission as converting hard-to-dispose organic waste, slash from mitigation work, diseased wood, understory material and other nonmarketable wood, into biochar, a carbon-rich, charcoal-like soil amendment created by heating organic material in low-oxygen conditions. The county frames that throughput as a direct wildfire benefit, equating 10,000 tons of processing to “10,000 fewer tons of fuel” that could otherwise feed future wildfires. Dylan Williams, Douglas County wildfire mitigation and resilience coordinator, calls biochar the “next level of wildfire mitigation.” Williams added, “The goal is to have more acreage treated and take the profit (from biochar sales) and put that into the mitigation program.”

Douglas County Public Works staffer Daniels projects the business case for the Sedalia plant will generate gross annual revenue of $2,000,000 to $2,200,000 from biochar sales against roughly $1,500,000 in annual operating costs, a gap the county says will lead to break-even in “just under a decade.” County messaging stresses that future sales are intended to make the mitigation program self-sustaining rather than serve primarily as a profit center. Academics have urged caution; Summers, a University of Colorado professor, warned, “If they’re dependent on that economic model, they really need to make sure the market is there.”

The Douglas County Board of Commissioners has provided funding approvals for the project since 2024 and in December voted to approve an Intergovernmental Agreement with the City of Aurora to support development and operation. The IGA includes a $100,000 contribution from Aurora Water. Commissioner Abe Laydon, founder and chair of the Douglas County Wildfire Action Collaborative, said, “Douglas County is proud to lead the nation with the first county-operated biochar facility, a milestone that reflects our commitment to innovation in wildfire mitigation and land stewardship.” Laydon added, “This partnership with the City of Aurora demonstrates how regional collaboration can produce meaningful, lasting benefits for our residents and our natural environment.”

County public messaging envisions the Sedalia site evolving into a regional “one-stop-drop” that would accept not only mitigation slash but hazardous household chemicals, residential yard waste, electronics and other materials. Douglas County’s motto around the project is “Supporting our neighbors,” with materials stressing, “Wildfires don’t stop at county lines. When the threat of wildfire is mitigated, we all benefit – our forests, our water, our communities, and our health.”

Timing remains framed in county posts and project renderings as imminent: county materials and a Douglas County LinkedIn post state the plant “will begin construction soon” and refer to launching “this year,” and the county invited residents to a public open house on Wednesday, Jan. 28 to learn more. The “nation’s first” claim is presented as a county assertion and has not been independently verified; the economic projections depend on market demand that county staff and outside experts say will need confirmation as permitting, off-take agreements and construction timelines are finalized.
