Biomass into a thousand-year carbon sink.
Biochar is a stable, carbon-rich solid made by heating biomass — forestry residue, agricultural waste, sustainable energy crops — under low-oxygen conditions. The result is a porous, durable material that locks carbon away for centuries and improves the soil it ends up in.
Pyrolysis: heat without oxygen.
At 400-700 °C in a sealed reactor, biomass breaks down into three things: combustible gases (which power the reactor itself), bio-oils (used as a renewable fuel), and a stable carbon skeleton — biochar. The carbon that took a tree decades to fix from the atmosphere is now locked into a form that resists decomposition for 1,000+ years.
Sustainably sourced biomass
Forestry residue, agricultural waste, or dedicated energy crops with chain-of-custody documentation.
Low-oxygen pyrolysis at 500-700 °C
Reactor parameters (temperature, residence time, particle size) are logged per batch.
Stable biochar + bio-energy co-products
Carbon content ≥ 60 % by mass, with end-use determined by the buyer's application.
One of the few carbon-removal pathways the registries accept.
Tree planting is reversible — a wildfire releases everything. Direct air capture works but is expensive at scale today. Biochar sits in the middle: durable, scalable, measurable, and with co-benefits for soil health.
Scalable
Existing pyrolysis tech, no new physics. UK alone has ~10 Mt/yr of biomass residue that could be diverted to biochar.
Measurable
Carbon content, mass, and persistence are physical properties of the batch — testable in a lab, not estimated.
Soil-positive
Improves water retention, nutrient cycling, and soil microbial activity. The same tonne removes CO₂ and helps a farmer.
Circular
Turns a waste stream into a stable carbon product plus renewable energy. No net land-use change.
Built around the biochar producer's reality.
If you're operating a pyrolysis facility — from a 200 t/yr farm rig to a 50,000 t/yr commercial plant — the platform handles the paperwork so you can focus on operations.
- On-farm producers using crop residue or animal manure
- Forestry-adjacent operators processing harvest residue or invasive species
- Urban / industrial pyrolysis sites converting wood waste streams
- Co-operatives aggregating biochar from multiple smallholders
Producing biochar already? Let's get every batch on the books.
We onboard new producers in a few hours, not weeks.
