About
Sinkco Labs is a US-based marine CDR startup developing a micro-injection system that embeds waste biomass into anoxic marine sub-sediments for permanent carbon storage. The company was selected for the Breakthrough Energy Fellows Program and co-developed the Rainbow Standard’s Marine Sub-Sediment Burial (MSSB) methodology. Their approach also aims to rebuild coastal marshland and improve shoreline resilience alongside carbon sequestration.
