From waste stream to carbon sink—simple, scalable, verifiable.
Organic waste from cafeterias, restaurants, and food processing facilities is collected and dried instead of going to landfills.
Dried feedstock undergoes oxygen-limited pyrolysis at 400–600°C, producing stable, carbon-rich biochar with ~75% carbon content.
Biochar replaces up to 33% of cement by mass in standard concrete mixes. No workflow changes—just pour and cure as usual.
Our biochar concrete meets industry benchmarks for structural integrity. Ongoing ASTM C39 testing validates strength; literature supports thermal and durability benefits. Full in-house data to be published as batches complete 28-day cures.

| Cement Replacement | Target Strength | Application | Status |
|---|---|---|---|
| 5% | 4,500 psi | Standard structural | Available |
| 10% | 4,000 psi | General construction | Available |
| 20% | 3,500 psi | Non-structural, thermal upgrade | Testing |
| 33% | 3,000–4,000 psi | Pilot projects, R&D | Testing |
Note: Thermal conductivity and long-term durability testing in progress. Expected thermal insulation improvement ~15% vs. control (literature-based).
Every ton of biochar-enhanced concrete sequesters measurable CO₂. We're pursuing third-party verification to convert these reductions into tradable carbon credits under established registries (Verra, Gold Standard, or equivalent).
This creates a dual value stream: lower-emission construction plus potential offset revenue for project stakeholders.
Establish measurement, reporting, and verification protocols aligned with Verra, Gold Standard, or equivalent registry requirements.
Partner with accredited verifiers to audit biochar carbon content, feedstock provenance, and sequestration permanence claims.
Submit validated data and project documentation to carbon credit registry for formal project registration and approval.
Upon verification, carbon credits are issued and can be traded, retired, or held as offsets. Ongoing monitoring ensures compliance.
Real projects, real carbon reductions. Each pour demonstrates the viability of biochar concrete at scale.
