O.C.O Technology chosen as Mitsubishi Corporation’s sole UK partner in global drive to cut greenhouse gas emissions to net zero by 2050
A new Green Concrete
Consortium launched by Japan’s Mitsubishi Corporation has hand-picked O.C.O
Technology as one of only four global companies to deliver its goal of transforming
CO2 into carbon negative concrete and aggregates.
Work has already begun on a
project in Japan to assess the potential for carbonating new waste materials,
including slag waste from
steel processing plants.
a second important move, O.C.O has also applied to be part of a new
voluntary carbon credit offset programme being spearheaded by Microsoft and
other industry leaders.
Roscoe, O.C.O’s Technical Director, said: “These opportunities are a huge step
forward and put us firmly in the driving seat to demonstrate the role that carbon
capture, through the mineralisation of CO2, can play in combating
are delighted to be part of the Consortium and partnering with a global industrial
giant like Mitsubishi is a fantastic opportunity for O.C.O. Mitsubishi is also supporting
our proposal to participate in the Microsoft carbon credit purchase programme
and these two projects show how UK technology is delivering success on a global
carbon dioxide to transform unwanted waste materials into new carbon negative
products is a perfect example of the circular economy in action. It reduces the
need for natural aggregates and above all, it enables significant volumes of CO2
to be taken out of the atmosphere – something we all need to work towards to
improve the future sustainability of our planet.”
O.C.O, which has operations in
Leeds, Avonmouth and Suffolk, was the first company in the world to
successfully commercialise the Accelerated Carbonation Technology (ACT) process,
enabling the permanent capture of significant amounts of carbon dioxide.
So far it has used the
technology to treat Air
Pollution Control residues (APCr) from the Energy from Waste sector, using CO2
to create artificial limestone aggregates which have already been used in
around 21 million building blocks – equivalent to nearly 8,000 three-bedroom
forces with Mitsubishi Corporation’s Green Concrete Consortium, billed as
a combination of carbon capture and utilisation (CCU) mineralisation projects, is
enabling the O.C.O team to ramp up development of its technology.
Once initial laboratory tests
in Japan are complete, the next stage will be to analyse the processed steel
slags in the O.C.O laboratory in Avonmouth, followed by a move to larger scale
commercial trials in Japan.
At the same time, O.C.O’s success story has been recognised by Mitsubishi Corporation and its
partner carbon project developer South Pole, which responded to Microsoft’s Request for Proposals (RFP) last summer as part of
the technology giant’s search for carbon removal
has already announced its own goal of being carbon negative by 2030 and, if the
South Pole proposal is successful, it is hoped that O.C.O’s Leeds facility will
become a recognised carbon credit offset option for Microsoft. The verification
procedures for the Microsoft bid, together with yet to be announced new
initiatives in carbon credit trading, will allow the Mitsubishi Corporation
/ South Pole / O.C.O partnership to
offer carbon credits to other companies keen to offset their carbon emissions.
at the recent virtual Davos meeting of global business and political leaders,
Microsoft co-founder Bill Gates said money from the sale of offsets could help
to support the rapid growth of innovations such as low-carbon cement.
UN climate envoy and former governor of the Bank
of England Mark Carney, who launched the Taskforce on Scaling Voluntary Carbon
Markets in 2020, has already revealed plans to vastly increase the number of
carbon offsets sold, a project that the Green Concrete Consortium is also
keeping a close watch on, with Mitsubishi Corporation
a consulting member of the Task Force.
