Construction decarbonisation innovator Low Carbon Materials (LCM) has secured a £3m investment it says will fuel rapid expansion.

The Seaham-based creator of carbon negative aggregates used in building has closed its latest funding round led by Ada Ventures, and featuring Green Angel Ventures, Northstar Ventures, an Innovate UK grant and sponsorship and skills support from Deloitte. The former Earthshot Prize finalist, which employs about 18 people, said the funding was a crucial step for its growth.
