The UK’s second direct air capture plant is pioneering carbon-negative building materials made from CO₂.
Funded by the UK Department of Energy Security and Net Zero, we are partnering with waste management innovators O.C.O Technology to deploy a first-of-a-kind DAC system at their Wretham facility in Norfolk alongside their Accelerated Carbonation Technology (ACT).
Scheduled to become operational later this year, the containerised system will recover 250 tonnes of CO₂ from the atmosphere each year in a first-of-a-kind project turning atmospheric CO₂ and waste fly ash into carbon-negative manufactured limestone — a valuable building material.

Impact
Carbon removal and carbon utilisation
Using the CO₂ in our atmosphere to create essential building materials unlocks a sustainability ‘double benefit’ — displacing the use of fossil carbons used to create them whilst also permanently removing the planetary-warming gas from our atmosphere. Yet, for this high-value model to scale, innovators in the construction sector need to secure a reliable supply of atmospheric CO₂ at often highly distributed production sites.
Co-locating direct air capture (DAC) technology at building materials production sites offers one of the most sustainable pathways for decarbonising construction. By demonstrating production of carbon-negative building aggregate made from air, O.C.O Technology is leading the charge for a circular construction industry that transforms the urban environment into a valuable carbon sink.
We partner with pioneering CO₂ users, project developers, engineers, and scientists around the world to turn historic carbon waste into new climate value.
