CapChar has completed the first delivery and retirement of 8.6 tonnes of CO₂ removals under a 50-tonne prepurchase agreement with Bennetts Associates, a sustainability-driven UK architecture firm, and biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More producer Restord. The credits, generated on a Cornwall farm, are among the first to be issued under CapChar’s Biochar Carbon Code—a UK-specific standard for high-integrity carbon removal.

This agreement highlights growing demand for carbon credits that are both locally sourced and verifiably permanent. The credits were priced at £200 per tonne, well above industry averages, reflecting a market shift toward high-quality carbon removal solutions.

The carbon was sequestered through Restord’s use of CapChar’s on-farm pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More system, which converts agricultural biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More into stable biochar that is applied to soils for long-term storage. This method not only removes carbon from the atmosphere but also supports soil regeneration and agricultural sustainability.

Key stakeholders in the deal expressed confidence in the approach. Adam Samuel, Co-founder of CapChar, called the transaction “a vote of confidence in UK carbon removal.” Restord’s Co-founder Tom Previte noted that it sets a precedent for scaling durable carbon removal nationally. Ben Hopkins of Bennetts Associates emphasized the importance of traceable, local solutions to complement their broader climate mitigation strategy.

This is the first transaction to be certified under CapChar’s Biochar Carbon Code, which was recently opened for public consultation. The company aims to establish a national network of low-cost, farm-based biochar production facilities, supporting the UK’s transition to net-zero emissions.

CapChar has already commissioned projects in North Wales and Cornwall and will join other innovators at the upcoming Ashes to Action Climate Solutions Conference in Oxford on June 10.

With this pilot delivery, CapChar, Restord, and Bennetts Associates demonstrate how transparent, local carbon solutions can support both environmental and agricultural goals in the UK.
