What KIBAG does

KIBAG Group is a Swiss private construction company headquartered in Zürich, founded in 1926 and operating with 1,001-5,000 employees. The company delivers a diversified set of construction services spanning building materials, civil engineering, drilling, suction dredger, and sewer services to infrastructure and private-sector clients in Switzerland. Its operating geographies are concentrated in Switzerland, with primary activity centered in the Zürich region.

At the core of KIBAG's environmental-services vertical is the SORTAG facility in Rümland near Zurich, a wholly-owned subsidiary that processes 35,000 to 40,000 tonnes of mixed construction and demolition (C&D) waste annually into high-grade recycled concrete aggregate. The facility deploys STEINERT multi-sensor sorting technology combining near-infrared, laser, induction, and X-ray detection to identify and separate contaminants, including gypsum, achieving approximately 98% mineral purity and enabling output compliant with Swiss SIA 2030 standards.

KIBAG's business model is built on fee-for-service construction contracts, building materials supply, and the sale of recycled aggregates recovered from C&D waste streams. Strategic partnerships with STEINERT (sensor sorting) and Gravis Robotics (autonomous excavation retrofit technology) extend KIBAG's operational capabilities into circular-economy materials recovery and construction-site automation. The 2026 acquisition of Grob Kies indicates active consolidation in Swiss aggregates, reinforcing vertical integration in materials supply. Revenue mechanics (pricing, contract structure) are not publicly disclosed.

Partnerships

Two partnerships are on record, tiered core and minor.

STEINERTcoreTechnology or IntegrationSTEINERT provides sensor-based sorting technology to KIBAG's SORTAG facility in Rümlang near Zurich. The technology combines multiple sensor types (near-infrared, laser, induction, X-ray) to process 35,000-40,000 tonnes of mixed construction and demolition waste annually and achieve 98% mineral purity.
Gravis RoboticsminorOEM/ Whitelabel/ Licensing PartnerGravis Robotics, an ETH Zurich spinout developing autonomous excavation technology, has established OEM integrations with KIBAG. Gravis Robotics' retrofit autonomous systems are being deployed in partnership with construction firms and can boost construction output by 30%.

KIBAG competitors and assessment

Company assessment

Broad incumbents

Heidelberg Materials: Global aggregates, cement and ready-mix concrete producer with a strong European footprint and a dedicated circular-construction agenda (e.g., evoZero, RC products). Comparable as a broad incumbent in the recycled-concrete-aggregate and aggregates category.
CEMEX: Global building-solutions group in cement, ready-mix and aggregates, with explicit Circularity/Regenera programmes for construction waste. Comparable as an incumbent offering recycled-content concrete and aggregates competing in the same downstream market.
Martin Marietta Materials: Major North American aggregates producer with growing recycled-aggregates and low-carbon concrete offerings. Comparable as a broad incumbent in aggregates whose recycled materials and concrete products set the category benchmarks KIBAG's SORTAG output is judged against.
CRH: One of the world's largest building-materials groups, with cement, aggregates and recycled-aggregate operations across Europe and North America. Comparable as a broad incumbent spanning the same aggregates-and-recycled-products value chain as KIBAG's SORTAG business.
Holcim: Swiss-headquartered global building-materials major with cement, aggregates and recycling operations (including its ECOCycle and circular construction activities). Comparable because it shares KIBAG's Swiss base and aggregates-plus-recycling franchise at much larger scale.

Direct peers

Implenia: Largest Swiss construction services and civil engineering contractor, active in building materials, tunnelling and infrastructure. Comparable because it operates across the same Swiss construction-services stack as KIBAG (civil engineering, building materials, special services) and competes for similar Swiss public and private contracts.
Losinger Marazzi: Swiss general contractor and developer with sustainable-construction and circular-economy commitments. Comparable due to shared Swiss footprint, similar customer base and emphasis on lower-carbon, recycled-content building materials.
Walo Bertschinger: Major Swiss construction and civil engineering firm headquartered in Zürich, with growing circular-economy / recycling activities. Comparable due to overlapping Swiss infrastructure work and a parallel entry into construction-material recycling.

Others

TOMRA: Global sensor-based sorting technology provider (NIR, laser, XRT) competing with STEINERT in waste-stream sorting. Comparable as the closest technology substitute and potential competitive threat to the STEINERT stack that KIBAG's SORTAG depends on.

Emerging players

Aggregate Industries (Holcim-owned UK): Aggregates, concrete and asphalt producer owned by Holcim with strong recycled-aggregate product lines in the UK and Europe. Comparable because its recycled aggregates and low-carbon concrete directly mirror the SORTAG product set in a different geography.
