About
O.C.O Technology is a UK-based carbon mineralization company headquartered in Brandon, Suffolk, operating multiple plants that use Accelerated Carbonation Technology (ACT) to react CO2 with air pollution control residues from energy-from-waste facilities, producing carbon-negative manufactured limestone (M-LS) aggregate for construction. Originally Carbon8 Aggregates, it operates as a subsidiary of Grundon Waste Management, with CDR/carbon-negative aggregate production as its sole operational purpose.
