Environment Agency CEO visits O.C.O’s Avonmouth facility
Sir James Bevan, Chief Executive Officer of the
Environment Agency, visited O.C.O Technology’s Avonmouth facility on Wednesday
The two-hour visit gave him the chance to see the
company’s world-leading Accelerated Carbonation Technology (ACT) in action and
talk to its experts about future developments in the fight against climate
O.C.O’s ACT uses carbon dioxide gas to treat and valorise a wide
range of wastes, including Air
Pollution Control residues (APCr) from the Energy from Waste sector, turning it into carbon negative
aggregate – called
Manufactured Limestone (M-LS).
Because more CO2
is permanently captured than is used in the manufacturing process, it has been recognised as the
world’s first carbon negative aggregate and is increasingly
sought after as a sustainable building material.
Speaking afterwards, Sir James said: “What O.C.O Technology delivers as a
company is truly innovative: a technique of capturing carbon that turns
hazardous waste into a non-hazardous resource in a process that is net carbon
Environment Agency’s ‘End of Waste’ approval is rare and well deserved. I look
forward to developing our relationship further to support the delivery of UK
Net Zero targets.”
O.C.O’s Managing Director, Steve
Greig, hosted the visit alongside fellow directors Clayton Sullivan-Webb (also Managing
Director of Grundon Waste Management) and Non-Executive Director Stephen Roscoe.
Steve said: “We were
very pleased to welcome Sir James and his EA sustainability team colleagues to
“It was an
opportunity for them to see first-hand how our innovative processes turn
hazardous waste materials, which would otherwise have been sent to landfill,
into an award-winning carbon negative aggregate, with the power to make
savings versus more traditional building materials.
“We had a number of wide-ranging
discussions on topics including the potential for using M-LS in future EA
projects, O.C.O’s ongoing development plans, and our trials of new materials.
have a very positive working relationship with the EA, further strengthened by
this visit, and we thank Sir James for his encouraging comments.”
Last year (2021), a project
involving O.C.O’s M-LS earned top honours in the Towards Net Zero category of the
Environment Agency Flood & Coastal Excellence Awards.
The M-LS was a key
component in a groundbreaking low carbon asphalt mix used in the construction
of a low carbon cycle path, built for Birmingham City Council as part of the
Bromford Flood Alleviation Scheme.
O.C.O was one of a number of supply chain partners brought together by Jackson Civil Engineering on the building project for the Environment Agency. At the time, the award judges said the use of carbon negative aggregate on the flood defence cycle scheme was “a great step forward in the right direction and could be transformational if applied to flood schemes more extensively in the future”.
Estimates showed that the 2.5km new low carbon foamed asphalt path could deliver CO2 savings of more than 70 tonnes – equal to a 90% reduction – compared with using a traditional hot AC20 asphalt mix.
