Our purpose

To restore the carbon cycle through durable, waste-to-value infrastructure in Southern Africa.

Carbon removal only scales when it behaves like infrastructure. Every plant we build is designed to be three things at once:

Physical

Real plants on real sites, removing carbon you can measure and verify.

Permanent

Carbon locked into stable biochar that holds for centuries, not seasons.

Operated

Run as long-life assets, with reliable output and a clear operating record.

Deployment anchored in existing industrial waste streams.
The material

What is biochar?

Biochar is a stable, carbon-rich solid made by heating waste biomass, wood and plant residue, in the near absence of oxygen. The process is called pyrolysis. It takes the carbon that growing plants pulled out of the air and locks it into a form that resists breaking down.

Left to rot or burn, that biomass returns its carbon to the atmosphere within months. Turned into biochar, the carbon stays put for centuries. Under the EBC C-Sink standard, that permanence is certified beyond 300 years, well above emerging regulatory thresholds.

This is what makes biochar two things at once: a verified carbon removal and a useful material. The same tonne that removes carbon also improves soil, rehabilitates degraded land, or stores carbon inside building materials.

A carbon removal and a product, from a single output

Carbon in the air

Plants pull CO2 from the atmosphere as they grow.

Waste biomass

Timber, crop and invasive-plant residue is collected.

Pyrolysis

Heated without oxygen, the carbon is captured as biochar.

Carbon locked

Held in the ground or in materials for centuries.

What biochar does

Beyond locking carbon away, biochar earns its keep in the soil, on degraded land and inside industrial materials.

Healthier soil

Raises cation exchange capacity, holds nutrients against leaching, and gives soil microbes a stable home.

More water, less irrigation

Lifts water holding in sandy soils, with Western Cape field trials showing large gains and lower irrigation need.

Restores degraded land

Buffers acidic mine tailings and binds heavy metals, helping vegetation return to disturbed sites.

Lower-carbon materials

A stable additive that cuts embodied carbon in cement and concrete without weakening them.

Clears invasive species

Turns wattle, pine and hakea clearing into a revenue pathway, protecting biodiversity and water.

Locks carbon for centuries

Stable beyond 300 years and certified as durable removal, not a temporary offset.

The approach

Waste-first, infrastructure-led.

We co-locate at sites that already produce waste biomass, then turn it into a durable carbon asset and a useful product. One pathway, three steps.

1 Feedstock

Waste biomass in

Residues from timber, agriculture and invasive vegetation that would otherwise decay or burn.

2 Conversion

Modular pyrolysis

Containerised units heat biomass without oxygen, capturing the carbon as stable biochar.

3 Output

Biochar and removal

Certified biochar for the land, plus durable carbon removal credits backed by measured data.

Feedstock

Built for a wide feedstock window.

If it is waste lignocellulosic biomass, the plant can likely use it. We co-locate where the biomass already is: sawmills, cleared invasive stands, and farms.

Timber and forestry residue: logs, branches and offcuts

Sawmill and forestry residue

Offcuts, slabwood, branches and roundwood, loaded whole without grinding. The base feedstock at our reference plant.

Invasive alien species and woodchip feedstock
Invasive species

Wattle, pine and hakea

Aliens cleared under Working for Water become feedstock, turning a clearing cost into value while protecting water and biodiversity.

Agricultural residue: shells, pits and dense crop residue
Agricultural residue

Shells, pits and crop residue

Dense by-products and nutshells, ideal for high-grade biochar, sourced from regional growers and processors.

Coarse to denseWhole logs at 2 to 50 cm down to small dense shells, a broader range than continuous or rotary systems.
Below 15% moistureDrier feedstock runs best, with up to 30% tolerated and process heat available for upstream drying.
Tested before deploymentEvery feedstock is characterised and trial-pyrolysed to confirm yield and grade before a plant is committed.
The technology

Proven hardware. Verified carbon.

Biochar provides a modular, infrastructure-grade pathway to permanently remove residual emissions. We build on proven hardware from our technology partner PyroCCS, standardised so the plant can be repeated, module after module.

Gravity SCB pyrolysis

PyroCCS Gravity SCB units, a semi-continuous batch reactor that ships, installs and scales by adding modules.

EBC C-Sink certification

Carbon removal certified under the European Biochar Certificate C-Sink standard through Carbon Standards International.

Sarva OS and MRV+

Measurement, reporting and verification built into operations, capturing over 100 data points per cycle so every tonne traces to source.

Co-location model

Plants sit alongside existing industrial operations, securing feedstock at source and cutting transport and handling.

From module to site

A single four-chamber module runs biomass into biochar, bio-oil and energy. Sites scale by repeating the module, with handling, storage and dispatch built around it.

How we work together

Proven technology, delivered locally.

No single party builds a carbon removal plant alone. PyroSA brings together proven technology, project capital and a local operating team with the landowners who hold the biomass and the buyers who need the carbon. Each plays to its strength.

01

Proven technology

We deploy PyroCCS Gravity SCB systems, the same technology already operating at PyroNam in Namibia, so the hardware risk is retired before we break ground.

02

Site and feedstock

We co-locate with industrial and land partners who already produce waste biomass, securing feedstock at source under long-term supply agreements.

03

Operate and verify

A local team runs each plant, with Sarva OS and MRV+ tracking every batch from biomass intake to the moment the carbon is locked away.

04

Offtake and ownership

We connect output to biochar buyers and carbon markets, and every plant carries a 26% Worker Equity Trust, so the people who run it share in what it builds.

When the site, the team and the buyers all win, the plant works.

What your biomass is worth

Two revenue streams from one tonne.

Biochar earns twice: once as a product, and again as durable carbon removal. Enter your annual dry biomass to see what it could be worth, and adjust the assumptions to match your own numbers.

Illustrative estimate only, not an offer or a quote. Assumes a 32% biochar mass yield from dry biomass below 15% moisture, within the technology's certified 25 to 35% range, and around 2.25 durable removal credits per tonne of biochar. Actual yields, prices and credit volumes depend on feedstock, specification, supply-chain emissions and market conditions.
