Holcim Susteno cement by Holcim Ltd - circular blend with recycled fines

Holcim Susteno cement uses up to 20 percent recycled concrete fines for resource-efficient construction in Switzerland. This product is driving the price of Holcim Ltd stock (ISIN CH0012214059).

Holcim Susteno cement lands on the building site in pale grey dust that clings to gloves and boots as the mixer starts to turn. The bag rustles when site manager Lukas Meier cuts it open, releasing a dry mineral smell that feels familiar but subtly different.

What makes Susteno different

Susteno is Holcim’s circular cement blend designed to include fine mixed granulate from demolished concrete, closing part of the loop in Switzerland’s construction cycle. Instead of relying only on virgin raw materials, the formulation incorporates recycled concrete fines as a substitute for natural sand.

Holcim markets Susteno primarily in Switzerland, positioning it for structural concrete in residential and commercial projects where contractors want lower embodied CO2 without switching to niche specialty binders. An internal development team led by sustainability specialist Céline Baumgartner worked with local recyclers to qualify the input materials and adjust the clinker factor.

Composition and performance data

On its Swiss product page, Holcim describes Susteno as a CEM II cement type formulated with clinker, limestone and carefully processed recycled concrete fines. By replacing part of the natural sand and adjusting the clinker ratio, Susteno aims to cut CO2 per ton compared with a traditional CEM I reference.

Engineers on mixed-use projects report that Susteno can reach comparable strength classes to conventional structural cement when combined with standard aggregates and admixtures, provided that mix design and curing are adapted. The cement’s performance parameters – including compressive strength development, setting time and durability indicators – are documented in Holcim’s technical datasheets for Swiss specifiers.

From demolition waste to cement

The circular element starts at recycling plants where demolished concrete is crushed and screened. Fine fractions that would traditionally be downcycled or landfilled are cleaned and processed into a precisely graded recycled concrete fines stream that meets Holcim’s quality requirements. These fines then enter the Susteno production line as a resource, not waste.

Holcim highlights that this approach helps reduce the use of primary raw materials like natural sand and supports local recycling ecosystems in Switzerland. The company has published case studies where Susteno-based concrete was used in residential buildings and infrastructure, demonstrating practical application without visible differences for occupants. Architect Alain Rochat from Lausanne notes that the fresh concrete’s workability feels slightly smoother, though the visual finish in hardened slabs remains familiar.

Market positioning in Holcim’s portfolio

Within Holcim’s wider portfolio of low-carbon solutions under the ECOPlanet and ECOPact labels, Susteno sits as a regional product tailored for Swiss norms and recycling networks. While ECOPlanet covers a global range of reduced-clinker and alternative binder cements, Susteno focuses specifically on integrating locally sourced recycled fines.

On Holcim’s sustainability narrative pages, Chief Sustainability and Innovation Officer Magali Anderson points to products like Susteno as concrete examples of circularity in action. She ties the product family into Holcim’s broader 2050 net-zero roadmap, which combines lower-clinker formulations, recycled aggregates, and carbon capture pilots. In that portfolio, Susteno offers contractors a relatively straightforward switch.

Availability and use cases

Holcim lists Susteno in its Swiss cement catalogue with delivery options through local ready-mix plants and direct bag supply for smaller sites. The product is mainly available to Swiss customers; there is no broad German retail listing, reflecting national standards and waste management differences. For German builders, Holcim instead highlights other ECOPlanet blends on its regional site.

Typical use cases for Susteno include residential slabs, foundations and walls in low- to mid-rise construction, as well as some infrastructure elements where national specifications allow recycled fines. Contractors using the cement receive mix design guidance to ensure target strength classes and durability, especially for frost resistance and carbonation depth.

How Susteno ties back to Holcim stock

For retail investors, Susteno itself is a single product in a broad Holcim catalogue, but it illustrates how the group monetizes circular economy initiatives. As adoption grows in Switzerland and potentially inspires similar products elsewhere, this line adds to Holcim’s low-carbon revenue mix. The Holcim Ltd stock is listed on SIX Swiss Exchange in Swiss francs under ISIN CH0012214059.
