CarbiCrete obtains Environmental Product Declaration for cement-free concrete masonry units
21 November 2024Canada: CarbiCrete has obtained the first Environmental Product Declaration (EPD) for its cement-free concrete masonry units (CMUs). The products have specific CO2 emissions of 11.7kg/m3 for the CMUs, 94% below the industry norm of 200kg/m3. FinancialWire News has reported that CarbiCrete’s recipe for the CMUs replaces cement with steel by-products, while also sequestering CO2.
Concrete products company Canal Block is set to commence production of CarbiCrete CMUs at its Port Colborne plant in Ontario in early 2025.
Canal Block deploys CarbiCrete cement-free concrete technology at Port Colborne concrete block plant
15 January 2024Canada: Concrete block producer Canal Block has integrated CarbiCrete’s cement-free concrete production technology at its Port Colborne plant in Ontario. CarbiCrete’s technology produces concrete from steel slag. The integration at the Port Colborne plant commands US$2.24m-worth of funding from the global innovation cluster NGen, towards a total project cost of US$5.97m.
CarbiCrete CEO Chris Stern said "We are tremendously grateful for NGen's continued support, which is helping Canada position itself as the undisputed world leader in low carbon concrete."
Canal Block president Durk Bylsma said "Canal Block has had a long history of developing sustainable products for the masonry industry. We are excited to partner with CarbiCrete to bring this truly revolutionary technology to market and further our commitment to be an ecologically and socially responsible manufacturer."
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.”
Carbicrete secures US$1.5m funding from SQN Venture Partners
21 December 2020Canada: Carbicrete has secured US$1.5m in funding from US-based SQN Venture Partners (SQNVP). The funds will finance research and development activities at its new Lachine laboratory, as well as operations at its Drummondville pilot plant in Quebec. It said that this brings its total funding received from major investors in 2020 to US$8m with investment already agreed from Harsco Environmental, the Quebec Ministry of Energy and Natural Resources and Sustainable Development Technology Canada (SDTC). The technology company is developing concrete products made with steel slag for the construction industry.
Chief executive officer (CEO) Chris Stern said, “This venture debt cash injection following our equity financing further underlines the thesis that the financial markets are believing in value-added, carbon-negative technologies such as CarbiCrete that mitigate CO2 in our atmosphere. We are proud to have SQNVP as an investor in our company.”
Harsco invests in Carbicrete
13 December 2019Canada/US: Harsco’s Environmental division has invested US$2.3m in Carbicrete, a Canadian technology company developing concrete products made with steel slag for the construction industry. The investment will give Harsco Environmental a Board seat in Carbicrete and has been made in conjunction with a US$1.6m grant from the Government of Canada’s Sustainability Development Technology Canada Foundation and applications to further government grant programs. Harsco’s investment will aid the development of the technology through a demonstration program with support from a commercial concrete block manufacturer as part of a development consortium.
“This investment in innovation is aligned with Harsco’s on-going expansion into environmentally-focused products and services, and we are proud to support the development of this exciting technology,” said Harsco Environmental chief operating officer Russ Mitchell.
Carbicrete is developing a technology that allows the production of concrete without using cement by using steel slag instead. The concrete mix is poured into molds, like conventional concrete, and is then cured using CO2. During curing, the gas becomes a solid, binding together the slag granules, and giving the concrete its strength. Carbicrete says the process can be implemented in any precast concrete manufacturing plant. It also says that the technology is ‘carbon negative’ because more CO2 is consumed than emitted during the process.
