Carbonaide

Carbon-negative concrete: CO₂ is injected and permanently mineralised into the material during curing, replacing 20–50 % of the cement — a footprint of about −60 kg CO₂/m³ against roughly +250–300 for conventional concrete. VTT spin-off; co-founder Tapio Vehmas found the effect at VTT in 2018. Lakan Betoni (brand Lakka) is both the lead seed investor and the first commercial customer: a second-generation system goes into its Joensuu plant for production from Q1 2026, and Lipa-Betoni is installing one too.

How this row was decided

Every row on this map is checked by hand against the trade register and the company's own material, and placed in the sector that best describes its business or its technology. Service firms and consultancies are left out, however advanced the technology they work with — the test is where the revenue comes from. Only funding figures the company or its investor has published are shown. The full rules are on the landscape ↗
