Commercial carbon-capture and utlilisation brought to life in Victoria
Our Joint Venture
The City Circle Group and O.C.O Technology combine to bring carbon-capture technology to Victoria and turn thermal residues from waste into lower carbon construction materials.
Sustainable Aggregate
Our sustainable, carbon-neutral manufactured limestone is lightweight, durable and carries a lower carbon footprint than quarried materials.
Carbon Capture Technology
Our Accelerated Carbonation Technology uses CO₂ to convert thermal residues, which would otherwise go to landfill, into a carbon-neutral aggregate.
Two Partners
O.C.O Victoria is a joint venture between City Circle Group, Australia’s leading end-to-end construction and demolition recycling company, and O.C.O Technology, a pioneer in accelerated carbonation technology, manufactured limestone (M-LS) and world-leading carbon mineralisation removal credits.
Where we are
O.C.O Victoria is at the start. The joint venture is formed but first production is a couple of years away, so this is the moment for us to talk. If you produce residue or specify or buy aggregate, we would like to know how we can support your business.
Resource Recovery In Action
1 in 10
tonnes of Victoria’s waste is recovered by the City Circle Group.
4,000 trees
hold the same carbon as 1,000 tonnes of M-LS.
– 54kg of CO₂
is captured in every tonne of M-LS currently produced in the UK.
1.4 million
tonnes of recycled crushed concrete reused each year in place of quarried aggregate.
