O.C.O’s carbon negative aggregate at the heart of climate change statue
Carbon negative aggregate from O.C.O.
Technology is at the heart of a statue installed in Glasgow’s Merchant Square
during the current COP26 climate change conference.
Commissioned by Zurich Insurance Group
(Zurich), the interactive statue represents humanity standing in a circle that
represents the planet. Intended to symbolise solidarity and optimism, the aim
is for people to make a pledge to join the campaigners in fighting climate
One space has been left vacant and, when
someone steps inside the circle, they are invited to bump elbows with the figures,
connecting the final piece of the circle and uniting the world in the fight
against climate change. This can be done in person or virtually using an
augmented reality filter*.
Designed and sculpted by Edinburgh’s Powderhall Bronze, the
construction process saw 300kg of O.C.O’s manufactured limestone (M-LS)
combined with other environmentally-friendly materials, including recycled
plastic, to create the statue.
It is estimated that the statue, in
place throughout the two-week period of COP26, includes at least 10 per cent of CO2,
providing a tangible showcase for the practical abilities of carbon capture.
Steve Greig, Managing Director of O.C.O
Technology, said: “We are thrilled and honoured to be part of this exciting art
installation and hope it will touch the hearts and minds of everyone who sees
“The ability to successfully capture
carbon will be critical in the fight against climate change. Every year, we
already capture more than 20,000 tonnes of CO2, and that figure is
growing annually as we expand the business.
“Our patented technology allows us to go one step further too, not
just capturing the carbon but utilising it to transform waste CO2
into new and innovative products, such as the artificial aggregate used in this
“The statue is a great example of what can be achieved and we
wholeheartedly support Zurich in its celebration of people who are taking
action and in creating this symbol for change.”
With three operations across the UK, O.C.O
takes waste carbon dioxide (CO2) and blends it with Air
Pollution Control residue (APCr) from the waste processing industry. Because
more CO2 is permanently captured than is used in the manufacturing
process, M-LS has been recognised as the world’s first carbon negative
More traditionally used in building blocks
for the construction industry and low carbon building projects, M-LS is
becoming increasingly sought after by developers looking for more sustainable
