Circularity 

Cities are at the forefront of the shift to a circular economy. With an estimated two billion new urban residents by 2050, our cities need to become more circular to secure a sustainable future.

The Circularity Gap Report 2023, published by Circle Economy, estimates that the world is now only 7.2 per cent circular – meaning that only 7.2 per cent of the materials that we extract and use are being returned to the economy. 

A circular economy means shifting gears from a linear “take-make-waste” approach to a circular “reduce-recycle-regenerate” economy. A global circular economy can enable us to fulfil people's needs while reducing the materials we extract and use – making human activity compatible with the safe limits of the planet.

By reusing construction demolition materials in the production of new building solutions, we can:

  • Close the loop in construction to build new from old
  • Reduce the amount of waste sent to landfill
  • Reduce our dependence on virgin raw material
  • Make a positive impact on biodiversity by extracting fewer natural resources

Products

ECOPact®

ECOPact® combines lower-carbon concrete performance with a more resource-efficient approach to construction. 

Designed to reduce embodied carbon by at least 30% compared to ordinary Portland cement concrete, ECOPact uses supplementary cementitious materials to replace part of the standard cement content while maintaining the strength, durability and workability projects depend on. 

These materials can include industrial by-products such as fly ash, slag and silica fume, helping keep valuable resources in use and supporting a more circular construction system. From residential builds to major infrastructure, ECOPact helps customers lower carbon while building with confidence.

Aggneo®

Aggneo® is Holcim’s range of high-quality recycled aggregates, designed to support a more resource-efficient approach to construction. 

Produced from recovered construction and demolition materials, Aggneo® delivers the strength, consistency and reliability required for a wide range of applications, including roads, drainage and foundations. By keeping valuable materials in use for longer, Aggneo® helps reduce landfill, preserve virgin natural resources and support circular construction at scale. 

From civil works to broader infrastructure and building projects, Aggneo® helps customers build new from old with confidence.

Humes FutureCast Railway Station Sunrise
FutureCast

FutureCast by our Humes division is Holcim’s lower-carbon precast concrete range, designed to bring greater transparency and confidence to modern construction. 

With a minimum of 25% supplementary cementitious materials, FutureCast helps reduce the embodied carbon impact of precast concrete while maintaining the strength, durability and consistent performance required for infrastructure and building projects. 

Backed by third-party verified Environmental Product Declarations registered with EPD Australasia, FutureCast gives customers clearer insight into product impacts at the planning and design stage. Compliant with Australian Standards, it offers a practical way to support more responsible construction without compromising on performance.

Circular Cities Barometer

Cities are at the forefront of the shift to a circular economy. With an estimated two billion new urban residents by 2050, our cities need to become more circular to secure a sustainable future.

We created the Circular Cities Hub with Bloomberg Media Studios to showcase what the world’s most advanced cities are doing to fast track the shift to circular living and building.

Concrete Recarbonation

Recarbonation is a process that, in effect, recycles carbon dioxide (CO2). We have been achieving some breakthrough innovations at our R&D labs in Lyon, France, to recarbonate recycled old concrete, with CO2 and use it for other building material applications. Our results are game-changing. They open the potential to re-use untreated CO2 at industrial sources, to create higher-performing materials for building.
