What O.C.O Technology does
O.C.O Technology Ltd is a UK-headquartered waste management and carbon capture company founded in 2010 (originally as Carbon8 Aggregates Ltd, rebranded 2019). The company commercialises its patented Accelerated Carbonation Technology (ACT), which permanently captures carbon dioxide by reacting flue- or process-sourced CO2 with alkaline waste materials in the presence of water to form calcium carbonate, producing a manufactured limestone (M-LS) marketed as the world's first carbon-negative construction aggregate.
The business operates three UK factories (East Wretham, Avonmouth, Leeds) with combined processing capacity of 188,000+ tonnes of waste annually and 250,000 tonnes of aggregate output, representing approximately 35% of UK Air Pollution Control residue (APCr) treatment. Its activities extend internationally through the Biscay Eco Aggregates joint venture with Petronor in Spain (€20 million investment, operational 2026, 25% O.C.O stake), the Carbonel brand in Asia via Kobelco Eco-Solutions, and initial shipments of M-LS to block manufacturers in Australia. The company also partners with Mitsubishi Corporation as one of four global members of the Green Concrete Consortium and with Mission Zero Technologies on Direct Air Capture integration.
O.C.O Technology generates revenue through four streams: (i) per-tonne sales of M-LS carbon-negative aggregate to construction customers for blocks, precast, readymix, and asphalt applications; (ii) sale of verified carbon removal credits (CORCs) via the Puro.earth registry and Patch platform to corporations and financial institutions; (iii) technology licensing and equity participation in international joint venture facilities; and (iv) long-term (5-10 year) waste treatment contracts for APCr and other industrial residues from Energy-from-Waste operators. The customer base spans EfW operators (Lakeside, Ferrybridge Multifuel 2, Tilbury Green Power, Indaver), construction firms (Jackson Civil Engineering, WA Limestone), and notable carbon credit buyers (Microsoft, Swiss Re, Rothschild & Co). FY2021 turnover stood at approximately £20 million with a stated management target of £50 million for 2026.

O.C.O Technology product offering
Product offeringCore offering
O.C.O Technology commercialises its patented Accelerated Carbonation Technology (ACT) to permanently capture CO2 as stable calcium carbonate while transforming hazardous Air Pollution Control residues (APCr) into carbon-negative aggregate (M-LS) sold to construction buyers. The company also generates and sells verified CO2 Removal Certificates (CORCs) via the Puro.earth registry and licenses ACT internationally through joint ventures.
Product overview
O.C.O Technology operates a unified platform built around its patented Accelerated Carbonation Technology (ACT), which transforms the company's core Manufactured LimeStone (M-LS) into a carbon-negative aggregate for construction. The platform integrates waste treatment services that receive and process Air Pollution Control residues, combine them with captured CO2, and output certified construction aggregates. Carbon Removal Credits (CORCs) are issued as a byproduct of the mineralisation process. The product portfolio includes regional variants: Eco Aggregate manufactured in Spain through Biscay Eco Aggregates joint venture, and Carbonel™ branded technology for Asia via Kobelco partnership. Foamix Eco extends the platform into low-carbon asphalt applications. All products are underpinned by the same ACT core technology that permanently captures and mineralises CO2 into stable carbonate minerals.

O.C.O Technology competitors and assessment
Company assessmentDirect peers
- CarbonCure Technologies: Canadian company that injects captured CO2 into concrete during production to permanently mineralize it. Directly comparable to O.C.O in CO2 utilization for construction materials, though CarbonCure focuses on ready-mix concrete rather than aggregate.
- Carbonaide: Finnish startup using CO2 mineralization to produce carbon-negative building materials, including concrete products. Closely aligned with O.C.O's M-LS approach, with comparable end-use in precast and construction applications.
- CarbonOrO: Belgium-based company mineralizing CO2 into calcium carbonate from industrial waste streams. Comparable to O.C.O in combining waste valorisation with carbon capture through carbonation chemistry.
- Solidia Technologies: US company using CO2 curing for concrete and carbonated binders. Directly comparable to O.C.O in CO2 utilization for cement/concrete applications, though focused on curing rather than aggregate production.
- Carbon8 Systems: Canadian company accelerating carbonation of CO2 into stable aggregates from industrial waste. Closely analogous to O.C.O's ACT process, treating similar waste streams into construction products.
Emerging players
- Carbonova: Canadian CO2 utilization company (formerly Carbon Upcycling Technologies) converting CO2 into performance materials including construction fillers. Comparable to O.C.O's M-LS aggregate strategy with emerging-stage positioning.
- Mineral Carbonation International: Australia-focused mineral carbonation company developing technologies to permanently store CO2 in stable carbonates. Comparable to O.C.O's mineralisation approach, with regional overlap through O.C.O's Australian partnerships.
- Calix Limited: Australian technology company developing CO2 utilization for cement and building materials, including its LEILAC low-carbon cement technology. Comparable to O.C.O's mission of decarbonising construction materials through process chemistry.
Broad incumbents
- Heidelberg Materials: Major global cement and aggregates producer actively pursuing carbon capture and CCU in concrete products. While operating at much larger scale, Heidelberg's evoZero and similar initiatives place it in direct competition for low-carbon aggregate customers.
Others
- Mission Zero Technologies: UK-based DAC technology company partnering with O.C.O to integrate direct air capture with mineralisation into carbon-negative aggregate. Listed as a partner rather than competitor, but a relevant benchmark for adjacent carbon capture innovation.
