Swiss carbon removal specialist Neustark’s first carbon capture project in the UK has commenced operations, marking a step forward in supporting circularity and decarbonisation efforts in the construction industry.
This initiative is designed to capture and store carbon dioxide within recycled concrete, effectively transforming construction waste into a carbon sink.

The first operational site in Greenwich, London, is set to remove and store 1,000 tonnes (t) of net carbon dioxide (CO₂) annually, supporting local building projects in the process.
The UK site is the result of Neustark’s collaboration with building materials supplier Aggregate Industries to introduce the technology in the country.
Neustark has already established 19 carbon capture and storage sites across mainland Europe.
Aggregate Industries, part of the global Holcim Group, joined forces last year with Neustark to accelerate the adoption of sustainable products and support green growth within the UK’s construction sector.

By GlobalDataThe construction industry is reportedly a major contributor to global carbon emissions, with cement production alone accounting for 7%.
The partnership aims to address this challenge by utilising demolished concrete, the largest waste stream in the world, as a means to store carbon.
Neustark’s technology captures CO₂ from biomass sites, liquefies it, and injects it into mineral waste streams such as demolished concrete through a process called mineralisation.
Each tonne of demolished concrete has the potential to store approximately 10kg of CO₂.
The UK government has shown support for carbon capture and storage technology with a £21.7bn ($28.03bn) investment pledge.
Neustark has already demonstrated its capability by removing more than 2,500t of CO₂ from the atmosphere since its commercial launch in 2023.
With its strategic partnership with Holcim Group, Neustark plans to expand rapidly, aiming to establish approximately 40 additional sites in Europe by 2025.
Aggregate Industries UK CEO Lee Sleight said: “Our partnership with Neustark takes the battle to reduce carbon emissions in the construction industry to the next level. Together, we can remove carbon from the atmosphere and permanently lock it into recycled concrete, which can be used again in new construction projects.
“We are excited to get this technology set up in London, where there is direct access to a huge supply of demolished concrete. And this isn’t just carbon removal, it’s a reinforcement of a circular economy enabling the reuse of a major waste stream.”
