Scottish Water is considering the use of new production technologies that are cutting carbon from concrete across their sites, significantly reducing emissions
Working with aggregate supplier, Breedon Aggregates, Scottish Water are investigating the use of techniques that are cutting carbon from concrete across their sites in Scotland.
Two new types of concrete have been developed using production techniques that cut up to 70% of emissions, compared to traditional concrete.
Concrete manufacturing is one of the largest sources of carbon emissions
David Lavery, project manager at Scottish Water said: “If the manufacturing of concrete was a country, globally it would be the third largest producer of carbon emissions, producing around 8% of the world’s total.
“While there have been numerous developments in concrete over the past 100 years, the basic process of making it has remained much the same since the Romans invented it.
“These new techniques cut the amount of cement needed which dramatically reduces the amount of carbon dioxide produced in the process.
“Given that concrete is such an important component in construction because of its strength and versatility, we can make significant reductions in our emissions by using lower carbon alternatives at our sites.”
This is the first instance of widespread adoption of Cemfree and CarbonCure
Scottish Water is looking to adopt two new products – Cemfree and CarbonCure – currently being rolled out by its supply chain partner Breedon Aggregates at its yards in Glasgow.
During the delivery of a recent project at Dalmarnock Wastewater Treatment Works, Aaron Lucid, business development manager from Cemfree said;
“It has been fantastic to be part of this innovative project with Scottish Water to help them reach their net zero targets.
“After carrying out vigorous testing and lab trials in collaboration with Scottish Water and Breedon, it’s exciting and rewarding to see Cemfree Concrete successfully be poured on-site in Glasgow, offering vast carbon savings to the project.
“It’s always a pleasure to work with likeminded people who are dedicated to cutting their carbon, and we look forward to supporting Scottish Waters use of Cemfree at every stage on their net zero mission.”
Cutting carbon in concrete is part of Scottish Water’s net zero targets
Scottish Water has committed to meeting net zero total emissions by 2040, and net zero operational emissions by 2030.
Gordon Reid, Scottish Water’s zero emissions general manager said:
“This is a really exciting development for Scottish Water.
“We have successfully trialled these products across a small number of sites over the last couple of years and I am delighted that we are using them more widely.
“As a business, we have made some incredibly bold and brave commitments in reducing our carbon emissions, and I believe these technologies will go some way to delivering on those ambitions.”
