A national exchange of OMRI · IBI · EBC-certified biochar for environmental remediation, agriculture & tree husbandry, construction, and animal operations — sourced from a verified producer network across three regions.
Specification-matched, certified material for every application — sourced from the same verified network.
Heavy metals · PFAS · Stormwater
BET >800 m²/g activated biochar for brownfield stabilization, fixed-bed filtration, stormwater bioretention, and PFAS adsorption.
Row crops · Orchards · Golf · Reforestation
NRCS 336-eligible carbon amendment improving water retention, nutrient cycling, and soil health across four agronomic applications.
Asphalt · Concrete · Stormwater · Soil
LEED-eligible, EPD/EN 15804-ready biochar for asphalt modification, concrete admixture, LID stormwater, and soil improvement.
Feed additive · CAFO · Manure mgmt
OMRI-listed biochar for feed efficiency improvement, ammonia and H₂S control, manure management, and CAFO regulatory compliance.
NextChar is not a single biochar plant. We are the connective tissue of a fragmented industry — an asset-light platform connecting verified regional producers with the engineers, agronomists, and operators who need consistent, certified material at scale.
We do not build factories. We empower verified producers with technology, QA/QC, and commercial channels they lack — turning a fragmented industry into a unified offering.
The McLaughlin Method runs on every truckload across the network: Moisture, Dry Total Ash, Mobile Matter, Resident Matter. One COA standard. Four markets served.
Our pyrolysis model layers three revenue streams in one pass — turning a customer's liability (waste wood, biosolids) into a measurable carbon asset.
Every lot in the NextChar exchange is tested to the most rigorous, transparent characterization framework in the U.S. biochar industry — developed by NextChar Technical Advisor Hugh McLaughlin, PhD PE, and the standard cited across IBI and EBC certification pathways.
Measured at delivery conditions. Ensures volumetric and weight specifications are met at point of application.
Total inorganic fraction. Determines suitability for contact applications and regulatory thresholds across all four markets.
Labile carbon compounds driven off at low temperature. A key quality indicator for adsorption performance and biological stability.
The stable, recalcitrant carbon fraction. Determines long-term sequestration value and carbon credit eligibility.
