UK: Switzerland-based Neustark has partnered with Holcim subsidiary Aggregate Industries to launch the UK’s first mineralisation plant in Greenwich, London. The small-scale mobile plant will sequester CO₂ in recycled concrete produced using fines recovered from construction and demolition materials (CDM). The plant is situated at an existing Aggregates Industries CDM recycling site. A large-scale plant with a sequestration capacity of 1000t/yr of CO₂ is due to follow in early 2025.

Neustark CEO Valentin Gutknecht said "Neustark and Holcim have been working together almost since the founding of Neustark five years ago. 1Mt of CO₂ durably removed from the atmosphere in 2030 – that’s our ambition. We’re already well underway towards the megatonne goal. Our strategic partnership with Holcim represents a significant part of this roadmap. It will be a true catalyst to further scale up the permanent carbon removal impact that we generate in the next few years.”

Aggregate Industries CEO Lee Sleight said that the partnership would turn London into ‘one of the world’s largest urban mines.’ He said “This isn’t just a great carbon removal innovation but a great circular economy innovation, where we are taking what was once a waste stream and reusing it, saving us from digging up virgin materials in the first place."

Neustark has so far sequestered 2500t of CO₂ in circular concrete for use in further construction.

Switzerland: Carbon capture and storage (CCS) equipment developer and supplier Neustark says it plans to more than double the number of its CO₂ storage sites in Austria, France, Germany, Switzerland and the UK to 34 from 14. Neustark’s process turns mineralised captured CO₂ and existing mineral waste streams into useful limestone. Building materials producers lease Neustark’s storage sites to produce reduced-CO₂ alternatives such as recycled concrete. The sites currently have a total storage capacity of 5000t. Existing customers include Holcim.

Neustark CEO Johannes Tiefenthaler said “Neustark is scaling up rapidly, and we’re well on track to achieve our aim of permanently removing 1Mt of CO₂ by 2030. Our global goal is a series of reliable, region-specific CCS facilities that can be replicated anywhere, offering immediate sustainability benefits to local supply chains.”
