Neustark announces upcoming rapid expansion in Europe
19 January 2024Switzerland: 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.”
CarbiCrete secures steel slag supply from Lafarge Canada
15 December 2023Canada: Carbon-negative concrete producer CarbiCrete has signed a deal with Holcim subsidiary Lafarge Canada. Under the deal, Lafarge Canada will process steel slag at its St. Constant cement plant in Québec for use as an ingredient in CarbiCrete’s CO2-cured cement-free concrete.
CarbiCrete partner Patio Drummond produces carbon-negative concrete blocks using CarbiCrete’s technology at its Drummondville concrete block plant in Québec. The company is on a drive to double the production of CarbiCrete blocks. It first partnered with CarbiCrete during trial production of its material in 2018.
Lafarge Canada vice-president of cement Andrew Stewart said “We are committed to reducing our environmental footprint and leading the way in sustainable construction. Our partnership with CarbiCrete is a testament to our dedication to offering sustainable solutions and actively participating in the circular economy.”
CarbiCrete CEO Chris Stern said “Collaborating with Lafarge allows us to leverage long-established infrastructure and years of expertise in processing steel-related by-products. This enables us to make an immediate climate impact as we scale the deployment of our technology which reduces embodied carbon in concrete by both avoiding emissions and removing carbon through mineralisation.” Regarding the on-going scale-up of production at Patio Drummond’s Drummondville plant, Stern said “Increased production of our carbon-negative blocks brings us closer to our common goal of decarbonising production of the world’s most consumed man-made substance.”
Bahamas: Partanna Global has unveiled its first carbon negative, climate-resilient Home for the World in Nassau. The residence will remove 182.6t/yr of CO2 from the atmosphere. It is the first of 30 planned units, as part of a project to eventually build 1000 Homes for the World in partnership with the Bahamian government.
