Biochar
Stircor’s biochar solution transforms biosolids into a stable, carbon-rich material that improves soil health, enhances nutrient retention, and supports long-term carbon sequestration.
Key Benefits
Produced through a controlled thermal process, biochar offers measurable agricultural, environmental, and economic benefits for municipalities, industrial operators, and growers. Delivered through Stircor’s Partnership-as-a-Service model, our biochar solution gives facilities a sustainable, value-creating outlet for their waste streams—without capital investment or operational burden.
Improved soil structure and nutrient retention supporting healthier crops and stronger yields
Enhanced water-holding capacity reducing drought susceptibility
Increased pH stability and soil carbon levels for long-term soil resilience
Carbon sequestration through a stable, long-lasting form of carbon
Versatile agricultural use compatible with no-till drills, air seeders, spreaders, and traditional fertilizer equipment
Customized product options including straight biochar, biochar + gypsum, and biochar + lime blends
Revenue or cost-offset pathways including NRCS Soil Carbon Amendment (336) programs for qualifying agricultural partners
Produced from Stircor’s high-quality, consistent gasification outputs ensuring purity and performance
The Biochar Process: How It Works
Stircor produces biochar as part of its thermal conversion process, turning biosolids into a carbon-rich material optimized for agricultural and environmental applications.

Thermal Conversion
Biosolids are treated in an oxygen-limited environment, creating a stable carbon structure while destroying contaminants.
Material Stabilization
The resulting char is cooled and processed for uniformity, ensuring a clean, dust-controlled product.
Enhancement & Formulation
Biochar is densified or blended (e.g., with gypsum or lime) to improve handling, nutrient profiles, and soil performance.
Markets We Serve
Municipalities
Cut disposal costs and create a cleaner, more stable material.
Cities reduce hauling needs, improve sustainability, and unlock beneficial-use options with Class A–ready biosolids — all through a fully managed on-site solution.
Industrial Facilities
Improve waste handling and reduce long-term operating costs.
Industrial operators benefit from a predictable, lower-volume material that’s easier to store, transport, and manage.
