Queens Carbon, a developer of next-generation cement technology, announced it has secured $10 million in seed funding to scale its platform for energy-efficient cement and supplementary cementitious materials (SCMs). The round was led by Clean Energy Ventures with participation from Plug and Play and Clean Energy Venture Group. Buzzi Unicem USA, a subsidiary of Buzzi S.p.A., one of the world's leading cement producers, also joined as a strategic investor and development partner. Queens Carbon plans to leverage the funding and partnership to expand its team and operations, construct a 2,000-ton-per-year demonstration pilot facility, and prepare for a full-scale, first-of-a-kind commercial plant.
