The building materials industry is under considerable climate pressure. Holcim, one of the world's largest cement manufacturers, is positioning sustainability no longer as a marketing topic, but as a central competitive factor. This strategic shift has direct implications for the entire value chain – and thus also for the requirements for construction machinery, recycling equipment, and compaction technology.
CO₂ reduction shifts priorities in material transport
The decarbonization of cement production does not begin in the factory, but already in raw material extraction and transport. Holcim is increasingly relying on CO₂-reduced cement, which affects the entire process from the quarry to the construction site. For operators of wheel loaders and articulated dump trucks, this concretely means: The pressure to electrify or at least to use alternative drives increases considerably.
Cement plants increasingly require their suppliers and logistics partners to provide emission certificates. Those who continue to rely exclusively on conventional diesel fleets could be shut out of tenders in the medium term. Volvo Construction Equipment has already begun series production of electric articulated dump trucks – a development that is no coincidence timing-wise with the tightened sustainability goals of major building materials companies.
Recycling capacity becomes a bottleneck factor
A central lever for CO₂ reduction lies in increased use of recycled material. Holcim is systematically expanding its capacities for processing construction waste. However, the circular economy requires not only organizational adjustments, but also specific machine technology.
Modern crushing plants must work much more flexibly today than just a few years ago. Processing heterogeneous demolition material poses different requirements than processing primary stone material. Kleemann, a specialist in mobile crushing and screening technology, is responding with adapted concepts. The green transition in crushing and screening plants is more than lip service: It's about wear optimization, energy efficiency, and the ability to process the most diverse input qualities.
For operators, this means: Investments in pure primary stone processing are becoming increasingly risky. Those who want to position themselves strategically must maintain equipment that can process both primary and secondary material. Jaw crushers and impact crushers with quickly replaceable wear parts and adjustable gap widths are becoming standard.
Mobile processing gains importance
Proximity to construction site material reduces transport distances and thus CO₂ emissions. Mobile crushing plants are therefore no longer a niche product, but are becoming the preferred setup for larger demolition and recycling projects. The ability to crush, screen, and reinstall material directly on site drastically shortens process chains.
However, this places high demands on logistics: Low-bed trailers for rapid transport of equipment between job sites, compact design for inner-city projects, and low emission values of the aggregates themselves. The expansion of construction waste recycling at Holcim makes these requirements the standard, not the exception.
Compaction: Quality over speed
CO₂-reduced cement has partially different processing properties than conventional mixtures. This has direct implications for compaction. Modern concrete mixtures with high recycled content or alternative binders require more precise compaction processes.
Compaction rollers with integrated measurement technology thus become a necessity rather than a premium feature. Quality control in compaction must be documented and reproducible – not only for inspection, but also for proof requirements towards certification systems.
BOMAG, a leading manufacturer of compaction technology, is increasingly focusing on digital networking. The Bomap Pave platform enables comprehensive documentation of compaction performance. Such systems will no longer be optional in the future when clients increasingly demand sustainability certifications.
Electrification of compaction technology
Parallel to the material side, electrification of compaction equipment is progressing. Smaller vibratory plates and rammers have been available with battery operation for years. For larger double drum rollers, the transition is just beginning. The electric rollers from Dynapac show that the technology is ready for series production – though still with limitations in operating time and power.
For construction companies that want to work with Holcim and other major building materials companies, the question will no longer be whether electrification will happen, but when. Those who invest early secure competitive advantages in the award of climate-sensitive large projects.
Earthmoving: Efficiency through digitalization
The requirements for earthmoving equipment are changing not only due to alternative drives, but also due to the need to move material more precisely. Every unnecessary trip, every incorrect movement costs energy and thus CO₂. GPS machine control and 3D machine control are therefore no longer luxury features.
Hydraulic excavators with digital assistance systems reduce fuel consumption by up to 15 percent – a magnitude that weighs considerably for large fleets. Caterpillar and Komatsu now offer such systems as standard. Those who, as operators, still plan and control manually, are wasting efficiency.
The decarbonization at Holcim reinforces this trend further: As cement becomes more climate-friendly, emissions from construction site logistics and machine operation come more into focus. The overall balance counts, not just the building material.
Attachments: Flexibility for changing materials
Processing recycled material requires adapted attachments. Excavator buckets must be more robust when increasingly reinforced concrete or material mixed with foreign matter is moved. At the same time, the need for sorting grabs and hydraulic shears for material processing increases.
Quick couplers are gaining importance because the variety of work steps on a recycling site is greater than in conventional earthmoving. A hydraulic breaker for breaking, a sorting grab for separating, a deep bucket for loading – all on the same day, with the same machine. Those who rely on manual changing here lose time and money.
Supply chains under pressure: Material availability and sustainability
Holcim's sustainability strategy also affects the supply chains of the construction machinery industry. Steel, hydraulic components, electronics – all supply areas are under decarbonization pressure. The introduction of green steel by SSAB is an example of how material standards are shifting.
For OEMs, this means: Those who want to credibly offer sustainable construction machinery must keep the entire supply chain in view. This drives costs, but also requires new partnerships. Manufacturers who early on rely on certified suppliers secure access to growing markets for sustainable construction projects.
Conclusion: Sustainability becomes a hard selection criterion
Holcim's sustainability strategy is not an isolated corporate course, but part of an industry-wide transformation. The requirements for construction machinery are changing fundamentally: Electrification, digitalization, flexibility in material processing, and demonstrable environmental performance become hard criteria in tenders.
Operators who today still rely primarily on conventional diesel fleets and manual control must rethink. Investment cycles in the construction machinery sector are long – those who buy wrong now will be sitting on equipment in five years that is no longer competitive. The impacts on OEMs are already noticeable: Development budgets are shifting, product lines are being revised, new partnerships are emerging.
The market is reorganizing itself – and this time not primarily by performance or price, but by carbon footprint. Those who ignore that will lose contracts.
