Circularity is an opportunity to deliver growth by using materials more efficiently.

CRH is creating business and customer value through our positive contribution to a circular economy. By introducing greater circularity across our business and supply chain, we can help solve our customers material resource challenges and create value for all. It also enables us to improve sustainability and reduce CO2 emissions. We are focused on delivering circular solutions that are longer lasting, have higher recycled content and can be reused, repaired, and recycled.

We are the largest recycler in North America and across our business we use 98 times more wastes and by-products, sourced internally and from other industries, than we send for disposal from our own processes. Through our $250 million Venturing and Innovation Fund, our Innovation Center for Sustainable Construction (iCSC), and CRH Ventures, we are building a pipeline of new business models and circular solutions.

Connecting Communities

Texas Materials, in CRH's Americas Division, recently partnered with the city of Dallas on the Luna Road project. It supplied asphalt which used four different recycled materials: 21% RAP, 12% RAS, 7% waste sand from roof shingles manufacturing and 28% used tire rubber-modified asphalt binder. Over 42% of virgin binder was replaced thanks to the use of these materials. In addition, warm mix asphalt manufacturing technology was used, lowering the energy requirements of the project.

Rethinking Material Use

CRH Concrete, in CRH’s International Division in Denmark, has been reusing whole pieces of recovered concrete components. This reduces a portion of the new concrete that is required, reducing the need for primary materials, including cement and aggregates. CRH Concrete collaborated with Tscherning, a Danish demolition company, to reuse concrete pieces from demolished buildings in Denmark reducing the CO2 emissions of the new elements by up to 26% compared to standard concrete elements.

Printing New Homes Using Less

CRH is developing the use of 3D concrete printing (3DCP), an innovative technology that utilizes large-scale 3D printers to construct structures layer by layer. It can help reduce waste, resource and energy use, and speed up construction time. Roadstone, in CRH’s International Division, recently provided readymixed concrete formulated for a 3DCP housing development in Ireland and partnered with HTL tech and the local county council on the project, a collaboration which streamlined the construction processes.

Embedding Circularity

At CRH, circularity is embedded within our business, processes and products. Staker Parson Materials & Construction, in CRH’s Americas Division, has completed the construction of the West Davis Corridor, Route 177, a new four-lane highway in Utah. The project repurposed 690,000 tonnes of mineral by-product to use as structural fill and used over 70,000 tonnes of recycled asphalt in the asphalt blend to pave the highway.


Our Targets and Progress


2025 target: 50% revenues from products with enhanced sustainability attributes1

2030 target: 95% of companies to have waste management plans in place

CRH’s Sustainability Framework is focused on how our products, services, and solutions can help to solve water challenges, enable a circular economy, and support progress towards a resilient, net-zero built environment. This includes building on our strong position in using wastes and by-products, sourced internally and from other industries to support the transition to a more circular economy. We take a collaborative, whole life approach to the design of products, buildings and infrastructure to eliminate waste, maximize resource efficiency and prolong the life-cycle of structures.

To embed circularity within our business, we set a target for 95% of our operating companies to have waste management plans in place by 2030, which we have already achieved. We will continue to drive forward on waste reduction and recycling and ensure newly acquired businesses are fully integrated into our target processes.

Our 2024 Performance:

  • 49% of our product revenues came from products with enhanced sustainability attributes1
  • 98% of our operating companies have waste management plans in place
