Our Policy
We drive circularity to reduce and reuse materials and natural resources
Headline KPIs
Circular economy
- Offer 50% circular alternatives for our concrete products.
Sustainable revenue
- Achieve 50% of our gross revenue from sustainable products that are either circular or low-carbon.
Enabling and supporting KPIs
Circular economy
- Zero non-production waste to landfill.
- 9 million tonnes of recycled aggregates processed.
- Development of circular economy strategy to include key milestones and detailed levers for achievement of KPIs.
Our Progress
Click to expand
| Our commitments | Our progress |
| Offer 50% circular alternatives for our concrete products | 78% of concrete supplied by Heidelberg Materials UK exceeded our sustainable revenue criteria. Overall, use of GGBS in our ready-mixed concrete in 2025 was 39%. |
| Achieve 50% of our gross revenue from sustainable products that are either circular or low carbon | The percentage of gross revenue from sustainable products in 2025 was: cement: 22% (low carbon); concrete: 78% (low carbon); aggregate: 0.8% (circular). Overall incorporation of RAP in asphalt was 19%. |
| Zero non-production waste sent to landfill | The level of non-production waste sent to landfill was 2.9% in 2025. |
| Process 9 million tonnes of recycled aggregate | We processed 966,000 tonnes of recycled aggregate (excluding Mick George and B&A Group), up from 725,000 tonnes in 2024. |
| Develop a circular economy strategy with key milestones and detailed levers for achieving circular products and business models | We progressed key circularity initiatives across our operations, including fully commissioning and operating our wash plant at B&A Group and constructing and commissioning a second in Manchester. Development of our SRF (solid recovered fuel) project continued, with Original Equipment Manufacturer (OEM) designs completed and the business case assessed. We also carried out technical assessments to evaluate the use of recycled aggregates in internal concrete applications at scale. In addition, we assessed potential outlets for filter cake generated by our wash plants, supporting our aim to maximise resource efficiency and reduce waste across the value chain. |

Circular and resilient in action
M5 Junction 26 concrete road replacement
We completed a major road improvement project at Junction 26 of the M5 and the A38 Chelston Link Road in Wellington for Somerset Council. B&A Group used an innovative technique called rubbilisation to break up the existing concrete road surface, allowing it to be recycled into sub-base for the new asphalt. We also supplied 17,000 tonnes of asphalt from our Whatley quarry, which used lower carbon options where possible to minimise its environmental impact.
Circular economy in action at Cheddar Gorge
We completed a night-time resurfacing project in Cheddar Gorge, the deepest natural canyon in the UK. Around 1,300 tonnes of worn road surface was removed and recycled, where possible, back into the new asphalt, which was produced at Whatley quarry.
New wash plant capacity for recycled aggregates
We extended our capabilities to recycle excavated waste at scale by investing in the UK’s largest wash plant at our Bristol-based B&A Group site. The new wash plant separates, washes and processes up to 400,000 tonnes of waste a year, diverting more material from landfill. A second wash plant was commissioned at our Agecroft site in Manchester and is expected to be operational in 2026.
