SL Materials has secured €100 million (USD $112 million) from Aviva Investors and ABN AMRO to scale its circular concrete platform, the Netherlands-based company announced.

The funding, drawn from Aviva Investors' Climate Transition European Infrastructure Fund and ABN AMRO's Sustainable Impact Fund, will bankroll capacity expansion at SL Materials' existing Zaandam facility and the development of additional production sites, the company said.

What does the platform actually recover?

SL Materials, founded in 2019 as Urban Mine, pulls sand, gravel and cement from demolished concrete and reprocesses the feedstock into raw materials engineered to match the technical specifications of virgin inputs. The company claims its output meets the strength, durability and certification thresholds of conventional concrete while delivering substantial embodied carbon reductions.

Cement production generates roughly 8% of global CO2 emissions, with industry estimates placing emissions intensity at more than 900 kg of CO2 per 1,000 kg of material produced. Investors have framed SL Materials' recycling route as a direct response to those ratios.

Who is leading the buildout?

Alongside the capital raise, SL Materials has installed James Cousins as chief executive officer and Steve Millburn as chief operating officer. The transaction was structured with Kingsley Capital, which contributed its UK circular-concrete platform Koreco as a wholly-owned subsidiary of SL Materials.

Cousins tied the new financing to the company's commercial track record:

"We have demonstrated that concrete recovered from demolition can be transformed at industrial scale into high-quality materials for new concrete, without compromising quality or technical performance. With the long-term backing of Aviva Investors CTEIF and ABN AMRO SIF, we can now build on that foundation, expand our capacity and establish SL Materials as a leading industrial platform for circular low carbon concrete."

What does Aviva see in the platform?

Angenika Kunne, head of infrastructure equity at Aviva Investors, framed the deal as a bet on operational scale rather than pilot-stage promise:

"SL Materials combines a proven track record of operating at commercial scale with what we believe is a compelling opportunity for further growth. Having demonstrated its ability to produce high-quality circular concrete that can compete with conventional products on both performance and economics, we see significant potential to build on that established platform, particularly through near-term opportunities to expand production capacity and develop new sites."

What's next for SL Materials?

The capital injection sets the company on a path to translate Zaandam's throughput into multi-site operations, with new production locations yet to be disclosed. The next milestones for operators, contractors and certification bodies tracking the sector will be:

• Site-selection announcements for the next circular concrete facilities
• Output volumes from expanded Zaandam lines
• Carbon-intensity verification of recycled sand, gravel and cement against primary benchmarks
• Integration milestones for Koreco's UK operations under the SL Materials parent

The regulatory and market test that follows is whether the recycled feedstock displaces virgin aggregate at scale on cost, certification and availability — the three benchmarks that decide whether circular concrete moves from single-site proof point to mainstream supply.
