Swiss cement manufacturer Holcim is repositioning itself after restructuring the group and placing sustainability at the center of its corporate strategy. This strategic realignment has consequences for the construction machinery industry. Because low-CO₂ cements, circular economy, and emission-free jobsite logistics fundamentally change the requirements for equipment.
New production processes demand adapted machinery technology
The production of CO₂-reduced cements requires different raw materials and aggregates than conventional cements. Blast furnace slag, fly ash, and calcium-rich clays increasingly supplement or replace conventional Portland cement clinker. These alternative raw materials place higher demands on the homogeneity and fineness of processing. This means for manufacturers like Kleemann and Metso that jaw crushers and impact crushers must work more precisely. Screening plants with finer meshes and larger capacities are also needed to achieve the required grain size distributions.
For the extraction of alternative raw materials in quarries and recycling plants, the requirements for hydraulic excavators and wheel loaders are also increasing. These must not only work more efficiently, but also become less emission-intensive themselves. Manufacturers like Caterpillar (https://www.caterpillar.com) and Liebherr (https://www.liebherr.com) already have battery-electric and hybrid models in their portfolio that are suitable for use in closed production halls and emission-sensitive areas.
Circular economy drives recycling equipment demand
Holcim's focus on circular building materials means a massive expansion of construction waste processing. Recycled aggregates, recovered binders, and processed demolition concrete become strategic raw material sources. This fundamentally changes the requirements for crushing plants. Mobile and semi-mobile plants are gaining importance because they can be deployed directly on demolition sites or in urban recycling centers.
Plant manufacturers must design their technology so that heterogeneous material streams with fluctuating qualities can be reliably processed. Reinforced concrete, masonry rubble with mortar residue, and contaminated components require robust feed systems, powerful magnetic separators, and multi-stage sorting and cleaning processes. Manufacturers like Kleemann (https://www.kleemann.info) are working on plant concepts that master this heterogeneity while simultaneously delivering standards-compliant qualities for use in new cements and concretes.
Demolition excavators with specialized attachments such as pulverizers, shears, and sorting grabs are also in high demand. They must be able to separate building components by type to ensure the quality of recycled materials. This requires hydraulic systems that can be precisely controlled and machines that have sufficient crushing force and reach.
Emission-free jobsite logistics becomes mandatory
If Holcim wants to optimize its CO₂ balance across the entire value chain, jobsite logistics also come into focus. This affects the transport, storage, and processing of cement and concrete. Electric and hybrid drives for wheel loaders, dumpers, and concrete mixers are becoming increasingly standard. Volvo Construction Equipment (https://www.volvoce.com) already has electric articulated dumpers in series that are suitable for closed material cycles in cement plants and on job sites.
Truck-mounted concrete pumps must also become emission-free if construction sites in urban areas are to meet strict regulations. Manufacturers like Putzmeister (https://www.putzmeister.com) and Schwing Stetter (https://www.schwing-stetter.com) are working on electric and hybrid pump systems that are not only locally emission-free but also reduce noise emissions.
Compaction technology must become more resource-efficient
Low-CO₂ cements often have different setting profiles and processing properties than conventional products. This has implications for concrete compaction and ground treatment. Compaction rollers and vibratory plates must be set to achieve the desired density without damaging or overloading the material. Manufacturers like BOMAG (https://www.bomag.com) and HAMM (https://www.hamm.eu) already offer intelligent compaction control systems that measure and document the achieved compaction in real time.
These systems will become even more important in the future to ensure that the required load-bearing capacities and durability are achieved even with new binder formulations. For road construction and civil engineering, this means closer integration between material science and machinery technology.
Digitalization and data management as key factors
The transition to low-CO₂ building materials requires precise documentation and quality control across all process steps. Telematics systems and GPS machine control are no longer just convenience features but become a basic prerequisite for demonstrating sustainable construction methods. Machine manufacturers must be able to collect, transmit, and integrate operational data, consumption values, and quality parameters into higher-level systems.
BIM (Building Information Modeling) is also gaining in importance because it makes it possible to make material flows and CO₂ balances transparent over the entire lifecycle of a building. Construction machines must be equipped with open interfaces that allow data exchange with planning and control systems.
What does this mean for excavator and wheel loader manufacturers?
Holcim's strategic realignment and similar industry players lead to concrete requirements for OEMs. First, the machines themselves must become less emission-intensive, whether through electrification, hybridization, or the use of alternative fuels. Second, they must be designed to handle new materials that have different abrasivity, moisture content, and flow properties. Third, they must be integrable into digital ecosystems to enable the required evidence and documentation.
Manufacturers like Komatsu (https://www.komatsu.com), Hitachi Construction Machinery (https://www.hitachicm.com), and JCB (https://www.jcb.com) are already responding with corresponding product developments. Electric and hybrid excavators up to 20 tons operating weight are now state of the art, with larger machines to follow.
Recycling technology providers must increase quality and throughput
For recycling technology providers, Holcim's sustainability course presents a dual challenge: on the one hand, they must increase throughput performance to meet the growing demand for recycled materials, and on the other hand, they must increase the quality of end products so that they are accepted as a full replacement for primary raw materials. This requires investment in optical sorting systems, AI-based quality control, and multi-stage processing processes.
Providers like Sandvik (https://www.rocktechnology.sandvik) and Metso (https://www.metso.com) already have corresponding systems in their portfolio, which are characterized by modular design and high degrees of automation. The challenge is to configure this technology in such a way that it meets the specific requirements of the cement industry.
Conclusion: Sustainability becomes a competitive factor
Holcim's realignment is more than a marketing strategy. It is an expression of regulatory requirements, increasing customer demands, and economic necessity. For the construction machinery industry, this means a fundamental shift in requirement profiles. Machines must not only be powerful and reliable, but also low-emission, data-integrated, and designed to handle new materials. Manufacturers who address these requirements early will be able to realize competitive advantages in an increasingly sustainability-oriented market.
