Cocoon Carbon, a UK firm growing a scalable provide of cement substitutes, often called supplementary cementitious supplies (SCMs), at the moment introduced the closing of a €13 million ($15 million) Collection A spherical.
The funding was co-led by 2150 and Brick & Mortar Ventures. The spherical included participation from TVC (The Enterprise Collective) and continued assist from current buyers Wireframe Ventures, Celsius Industries, Gigascale Capital, and SOSV.
“The SCM market is going through a structural deficit at precisely the second infrastructure demand is rising,” mentioned Eliot Brooks, CEO and Co-Founding father of Cocoon Carbon. “We’re targeted on delivering a plug-and-play answer that offers concrete producers entry to reasonably priced, native supplies – whereas bettering the economics of electrical steelmaking. Increasing provide is the quickest strategy to stabilize prices and decrease carbon in concrete.”
Cocoon Carbon’s Collection A comes amid a rising physique of funding into low-carbon building supplies and cement decarbonisation applied sciences throughout Europe.
Latest examples embrace Carbonaide, a Helsinki-based startup that raised €3.7 million to scale carbon-curing know-how for concrete; Co-reactive, which secured €6.5 million to advance CO₂ mineralisation processes; 011h, a Barcelona-based firm that raised €20 million for low-carbon building techniques; and Converge, a London-based agency that raised €19.4 million to optimise concrete by means of AI.
Collectively, these rounds signify over €49 million in current funding exercise in adjoining segments.
Inside this panorama, Cocoon Carbon’s strategy – targeted on scaling supplementary cementitious supplies (SCMs) from metal slag – positions it on the supplies provide layer, complementing different approaches reminiscent of carbon seize, mineralisation, and digital optimisation.
“Concrete is among the largest worth streams on the planet, offering the inspiration of our civilisation, from buildings to infrastructure to information facilities. It consumes orders of magnitude extra power than AI and emits extra CO2 than every other sector,” says Jacob Bro, associate and co-founder of 2150. “Cocoon stands out within the innovation panorama with a product that’s higher and cheaper than cement and delivers a real drop-in alternative product for the trade.”
Based in 2023 and led by co-founders Eliot Brooks, Will Knapp, and Freddie Scott, Cocoon seems to offer a scalable provide of a cost-competitive cement alternative – serving to producers meet rising infrastructure demand rapidly with out elevating prices.
As data center construction booms and international infrastructure doubles over the following 40 years, the widening provide hole of widely-used, low-cost supplementary cementitious supplies has made it a vital materials.
Cocoon’s low-capex, modular course of converts electrical arc furnace byproducts from rising, clear metal manufacturing right into a reportedly cost-competitive cement alternative that lowers the carbon depth of concrete manufacturing.
SCMs have traditionally come from closely polluting coal vegetation and iron blast furnaces. As these industrial processes are retired throughout the U.S. and Europe, the corporate says SCM provide is shrinking and incumbents are consolidating to lock in provide.
On the similar time, SCM demand is rising at roughly 6–7% per yr, and in a number of markets, SCM costs have already doubled since 2017 as provide tightens.
Cocoon offers a brand new supply of SCMs by changing an underutilised and strong provide of metal slag, a byproduct of electrical arc furnaces (EAFs), right into a low-cost, high-performance cement alternative. EAFs re-melt scrap utilizing electrical energy, in comparison with coal powered blast furnaces that flip iron ore into pig iron.
With tens of tens of millions of tons of metal slag produced yearly within the U.S.and Europe, and EAF steelmaking projected to double by 2050, Cocoon expands the home provide base concrete producers depend on to maintain prices steady.
Cocoon’s new product allegedly matches the efficiency of conventional SCMs whereas lowering the embodied CO2 of concrete by as much as 40%.
In contrast to different rising options to cement, Cocoon’s product is price aggressive and doesn’t demand a prohibitive “inexperienced premium” that has traditionally restricted uptake of recent options available in the market.
Reasonably than growing a standalone manufacturing course of from the bottom up, Cocoon developed a fast cooling know-how that retrofits straight into current EAF metal waste dealing with processes. Cocoon captures molten slag straight out of manufacturing and cools it 100x quicker than current applied sciences to provide a dependable SCM provide.
By working inside current techniques, Cocoon says they function with out excessive power inputs, excessive capital expenditure, operational disruption, or security compromises. Co-located at metal mills in areas of heavy trade, transportation prices (a significant factor of SCM’s delivered value) are minimised and the necessity for brand new logistics infrastructure is negated.
The Collection A funding will assist deployment of Cocoon’s first industrial demonstration facility in america. This mission will validate efficiency at industrial scale and set up the working monitor document wanted to finance a broader rollout throughout greater than 50 metal vegetation within the U.S. and Europe, with Cocoon’s plug-and-play strategy permitting for quicker deployment.
The corporate has already piloted its know-how at a serious metal mill and accomplished third-party validation of its materials in concrete purposes. Over the previous yr, Cocoon has constructed out its R&D facility and concrete testing lab in London.
Cocoon is doubling the crew dimension with the hiring of course of engineers, supplies scientists, and industrial crew members within the UK, in addition to plant operators and technical employees in america to assist deployment of the demo facility.
