Carbon8 Aggregates rebrands to O.C.O Technology Limited

UK-based carbon negative aggregate specialist Carbon8 Aggregates has changed its name to O.C.O Technology Limited, with immediate effect.

The move also means its award-winning aggregate, previously known as C8Agg, has been renamed M-LS (short for Manufactured LimeStone).

M-LS is created using O.C.O Technology’s Accelerated Carbonation Technology (ACT) process. M-LS is versatile product that has a multitude of uses in the construction industry.

It uses waste carbon dioxide gas to treat a wide range of thermal wastes and, as more carbon dioxide (CO?) is permanently captured than is generated during manufacture. The end result continues to be the manufacture of the world’s first truly carbon-negative aggregate.

Wide-ranging applications for the aggregate include blocks, precast and ready mix concrete, screeds pipe bedding and various other “road” applications. The company is one of only a few in the UK to hold the Environment Agency’s “End of Waste” agreement, classifying the finished aggregate as a “product”.

The company currently produces over 350,000 tonnes of carbon negative aggregate each year and, for every tonne of aggregate used, 1.4 tonnes of natural aggregate is saved.

Steve Greig, managing director, says the O.C.O Technology name is designed to more accurately reflect the company’s core knowledge and expertise and the wider opportunities that are presenting themselves on the world stage.

He said: “While our old name has stood us in good stead, as our aggregates product range develops and our specialist knowledge takes us into new and exciting areas both within the UK and overseas, we needed a new identity and a brand that encompasses the full scope of our expertise.

“As innovators and leaders in this sector, we believe the successes achieved so far are only a fraction of the future opportunities available. At a time when the world is demanding new products and new technologies to increase sustainability and minimise impact on our precious environment, the O.C.O Technology name provides the perfect springboard for us to build and expand, while also delivering the best possible solutions for all our customers.”

From its network of facilities in the UK, the business now boasts a £15 million turnover and employs over 90 staff. Since its formation it now recycles around 25% of the UK’s Energy from Waste APC arisings and has attracted significant interest in its technology from around the world. The company signed its first international deal in 2019.

Over the last month (August), a major rebranding project has seen the O.C.O Technology name and logo appear throughout the business. The new website is now active at
