UK first as Marley launches lower carbon concrete roof tile with evoZero cement

evoZero carbon captured near-zero cement is being used to create a lower carbon concrete roof tile for the first time in the UK.

Marley Edgemere 2.0 concrete interlocking tiles have a low Global Warming Potential, a Green Guide A+ rating and BES 6001 Excellent certification.

evoZero carbon captured near-zero cement gains its sustainability credentials from the use of carbon capture and storage (CCS) at our Brevik plant in Norway and chain of custody models.

As part of the Brevik CCS project, CO₂ emissions from the production of cement at Brevik are being captured at source and permanently stored beneath the seabed. This carbon reduction is then recorded in the Heidelberg Materials’ Carbon Bank. The facility is designed to capture around 50 per cent of the cement works’ emissions (c. 400,000 tonnes a year).

In the case of Edgemere 2.0, to avoid the transport emissions associated with shipping the product from Brevik, the carbon reduction is being transferred and attributed to our locally sourced cement through an Environmental Attribute Certificate (EAC).

This allows carbon reductions to be allocated to each individual Edgemere 2.0 order, with full traceability.

“The launch of this new roof tile from Marley demonstrates the versatility of application for evoZero cement and reflects a growing demand for lower carbon construction materials,” said Andy Murphy, Group Commercial Director.

“It allows architects, engineers and sustainability and design consultants to specify a product that lowers the carbon impact of a project without the need to rewrite or redraw the specifications.”

Stuart Nicholson, Managing Director at Marley, added: “Edgemere 2.0 is a significant step forward for Marley and the roofing industry. By introducing the UK’s first concrete roof tile to use carbon capture technology we are supporting the industry’s transition to lower carbon construction.”

We are also building a carbon capture facility at our Padeswood cement works in north Wales. This project builds on the success of Brevik and is designed to capture almost all (around 95 per cent) of the carbon emissions from the existing cement works – around 800,000 tonnes a year. It is expected to be operational and producing evoZero cement in 2029.

¹ Marley Edgemere 2.0 has a Global Warming Potential of 1.86kg CO₂e per square metre from cradle to gate.
