Biochar is one of the most durable and verifiable forms of carbon removal available. And Roundwood Solutions is on the pathway to generating verified Biochar carbon credits – CO₂ Reduction Certificates, or CORCs – through the Puro.earth platform.
Here’s what that means and why it matters.
What is Puro.earth?
Puro.earth is a carbon removal marketplace and verification platform that facilitates the trading of CO₂ Reduction Certificates (CORCs). Unlike traditional carbon offsets – which typically involve avoided emissions or forestry – CORCs represent engineered carbon removal: carbon that has been actively taken out of the atmosphere and stored durably.
Puro.earth is majority-owned by Nasdaq, and CORCs are issued in the Puro Registry – they can then be retired by buyers or traded on voluntary carbon spot markets. They are purchased by companies seeking verified, auditable carbon removal to meet Scope 1, 2, and 3 net-zero commitments. The buyer gets a CORC. The carbon stays in the ground.
What is a CORC?
A CO₂ Reduction Certificate (CORC) represents one tonne of CO₂ permanently removed from the atmosphere and stored. In the case of Biochar, the carbon is sequestered in a form that is stable in soil for centuries – not decades. It doesn’t burn. It doesn’t reverse. It doesn’t depend on a standing forest.
For corporate sustainability and ESG buyers, CORCs provide the documented, auditable proof they need for board-level disclosure and Scope 3 supply chain reporting.
How does Biochar generate CORCs?
When timber waste is converted to Biochar through pyrolysis, the carbon that was stored in the timber is locked into a stable form rather than released into the atmosphere. Each tonne of Biochar produced locks away more than a tonne of CO₂ – because Biochar is roughly 80–90% stable carbon, a single tonne typically represents around two to three tonnes of measurable, verifiable CO₂ removed from the carbon cycle.
Once a producer achieves full Puro.earth verification, each tonne of Biochar produced generates multiple CORCs – with the exact number set by the verified methodology – which can then be traded on the voluntary carbon market.
Why does this matter?
For any business purchasing timber with sustainability goals, the RWS circular operation offers genuine, documented sustainability credentials. The timber you purchase is part of an operation that sequesters carbon, regenerates soil, and is progressing toward verified carbon credit generation.
For operations with formal sustainability reporting requirements, RWS can provide documentation suitable for Scope 3 supply chain disclosure and ESG reporting.
Where is Roundwood Solutions on this pathway?
Roundwood Solutions has achieved Puro.earth pre-assessment – a key milestone on the pathway to full verification. Pre-assessment confirms that our operation and production methodology meet the foundational requirements for CORC generation.
We are actively progressing full verification through the Puro.earth platform. Once complete, each tonne of Biochar produced at our Tantanoola facility is expected to generate multiple verified CORCs.
The RWS Circular Loop: Timber waste feeds the gasifier. The gasifier powers our steaming operations. The Biochar regenerates the soil. The loop is closed. Nothing is wasted.
Roundwood Solutions – Forest to the Floor. Good for the Soil. Great for the Environment.
