The problem
Across Southern Africa, agricultural and forestry residues are often burned or left to decay, creating fire risks, emissions, and lost economic value. At the same time, industries face growing pressure to reduce carbon emissions while struggling to access credible, permanent carbon removal solutions. Degraded agricultural land and abandoned mine sites also require scalable restoration technologies.
PyroSA's approach
PyroSA designs, finances, and operates modular pyrolysis plants that convert forestry and agricultural waste into high-quality biochar. The biochar permanently stores carbon for hundreds of years while creating verified carbon removal credits and regenerative soil products. Each plant serves multiple markets, including agriculture, cement manufacturing, mine rehabilitation, and voluntary carbon markets, creating a diversified revenue model while reducing waste and restoring ecosystems.
Where it's used
PyroSA's first commercial facility (PyroPSP) is being developed in Oudtshoorn, Western Cape, with secured biomass supply from PSP Timbers. Its biochar is intended for regenerative agriculture, mine rehabilitation, cement and construction materials, and corporate carbon removal markets. The company plans to scale through a network of 12 modular plants across Southern Africa.
Impact
Permanent carbon removal, restored land, and new circular value from unavoidable waste.
Removes carbon permanently
Converts waste biomass into biochar capable of storing carbon for 300+ years while generating verified carbon removal credits.
Restores degraded land
Improves soil health, water retention, and mine rehabilitation using regenerative biochar products.
Creates circular value
Transforms unavoidable agricultural and forestry waste into valuable climate infrastructure, creating new income streams while reducing emissions.
Partners & ecosystem
PyroSA is building its platform with partners including PyroCCS, PyroNAM, PSP Timbers, NewCarbon, Afrimat, Biofarm Assist, DBSA Green Fund, Sumitomo Corporation Africa, Javan Fabrications, Sarva Carbon, and Wesgro.
