Lower carbon. Made for the mix you already pour. Chicago-based.
Biochar Concrete Solutions is developing engineered biochar, a stable, carbon-rich material from biomass that substitutes for a portion of the portland cement in a concrete mix. It's incorporated the way producers already use supplementary cementitious materials like fly ash and slag, with their existing batching, delivery, and placement. The carbon stays locked in the structure for its full service life, designed to lower the mix's footprint. The removal certificates for that stored carbon belong to BCS; producers get the lower-carbon mix.
BCS is developing its first Chicago-area production facility. Product is not yet available for sale or sampling; independent testing and certification are in progress.
Figures drawn from published industry research.
Designed to reduce portland-cement use and store biogenic carbon.
Most of concrete's footprint comes from cement. Biochar replaces a portion of that cement and puts durably stored carbon into the mix, using the batching and equipment producers already have.
Lasting Carbon Capture
Biochar holds its carbon in a stable form for centuries. Cast into concrete, that carbon stays in place for the service life of the structure. We will quantify that durability under a recognized carbon-removal methodology rather than promising it will last forever.
Built to Perform
We are engineering particle size, dosage, and moisture control so our biochar works as a supplementary cementitious material, substituting for a portion of the portland cement, used the way producers already batch fly ash and slag, with no new equipment anticipated.
Circular by Design
We will turn urban wood that would otherwise decay or be landfilled into durable biochar, keeping carbon and resources in productive use in the region where they came from. Feedstocks include arborist residuals, clean C&D wood, and industrial scrap.
A material the world depends on, with a carbon problem.
Cement is responsible for about 8% of global CO₂ emissions, and demand keeps climbing. Biochar is intended to lower the carbon in each yard produced.
