Zementwerk Rohrdorf

What Zementwerk Rohrdorf does

Rohrdorfer (legal entity: Südbayerisches Portland-Zementwerk Gebr. Wiesböck & Co. GmbH) is a privately held, family-founded German building-materials group headquartered in Rohrdorf, Bavaria, operating more than 160 production and distribution sites across Germany, Austria, Italy, and Hungary with approximately 2,100 employees. The group is vertically integrated across the construction-materials value chain: captive limestone quarries (Nußdorf, Ebensee) feed two cement works (Rohrdorf and Gmunden/Hatschek) producing Portland (CEM I), Portland-composite (CEM II), blast-furnace (CEM III), and CO2-reduced cements (notably Eco Fusion at 50% CO2 reduction vs. 1990); downstream operations span ready-mix concrete (Rohrdorfer Transportbeton across roughly 15 plants), precast components (RBW, Concrete Rudolph, Betonwerke Unterland, Betonwerk Linden, Ebenseer, Seesteiner, Weissenböck, Ganser), sand & gravel extraction (Rohrdorfer Sand & Kies, Neubeuern, Erlstätt), and dry mortar/specialty building materials under the Sakret and Rygol brands. Logistics rely on a long-standing 30-year rail partnership with ÖBB Rail Cargo Group using RockTainer SAND and CemTainer systems, supplemented by electric trucks (Mercedes eActros 600) for last-mile delivery.

The company's go-to-market is direct B2B sales via regional sales teams handling cement, ready-mix, aggregates, precast, and dry-mortar divisions, with negotiated project-based pricing (no public list). Customers are primarily construction contractors, public-sector infrastructure clients, precast manufacturers, and concrete-goods producers; anchor projects include the Brenner Base Tunnel (40,000 t Fluasit additive via CemTainer from 2026) and the City of Munich school build supplied with ~8,000 m³ RC-Beton. Revenue streams are essentially one-time product sales across the five divisions, with no recurring software or licensing component.

Rohrdorfer's strategic center of gravity is cement-industry decarbonization, executed through a wholly owned subsidiary, Net Zero Emission Labs (NZEL, founded 2023, 30 experts), which operates Aurora 1 (Germany's first cement CO2 capture plant, 2022, 2 t/day, amine scrubbing, 99.95% purity), a CO2-to-formic-acid electrolysis pilot, the iCCE intensified-capture-and-electrolysis Carbolyzer pilot (testing from June 2025), a tempered/calcined-clay pilot plant (C3Pi, 500 t output in 2025), and the CODE work package within the €40M+ H2-Reallabor Burghausen consortium targeting CO2-to-green-ethylene with Fraunhofer UMSICHT and Wacker Chemie. Ancillary units RSK Umwelttechnik (recycling, 2023) and the Gips³ gypsum-recycling JV with Freudlsperger (2025, live 2027) close the raw-material loop. The company targets exclusively net-zero cement by 2038 and 30% self-generated renewable electricity by 2033 under Initiative 3033; CSC Silver certifications across cement, precast, and ready-mix plants plus ISO 14001/50001 underpin eligibility for green public procurement and DGNB-rated projects.

Regional players

• Cementir Holding: Italian-headquartered cement producer with operations across Northern Europe (including the Aalborg White brand in Scandinavia) and a strong specialty cement focus. Compares on vertical integration and specialty product mix; competes primarily in Mediterranean and Nordic markets rather than DACH.

Direct peers

• HeidelbergCement-owned Spenner Zement: Mid-sized German cement producer operating clinker and grinding capacity in Germany. Smaller than Rohrdorfer but comparable in regional footprint, product range and customer segments within western Germany.
• Vicat SA: French-headquartered international cement, ready-mix concrete and aggregates group with European operations and an active decarbonization roadmap. Comparable in scale and product mix, with similar emphasis on low-CO2 product innovation.
• Dyckerhoff (Buzzi SpA): German cement producer owned by Italy's Buzzi SpA; operates cement, ready-mix and aggregates operations across Germany. Direct regional competitor with overlapping product portfolio and similar DACH decarbonization roadmap.
• Schwenk Zement: Privately held German cement manufacturer headquartered in Ulm, operating cement works and grinding plants in Germany, Austria and surrounding regions. Closest mid-sized regional peer to Rohrdorfer in scale, footprint (DACH) and product range.
• Heidelberg Materials: Germany's largest cement manufacturer with global operations across cement, aggregates and ready-mix concrete. Directly comparable as a DACH-based competitor selling Portland/composite cements and competing for the same green-procurement and CSC-certified public tenders as Rohrdorfer.

Others

• SAKRET (Rygol/Sakret branded) - not peer: Not a comparable peer (Sakret is a Rohrdorfer sub-brand itself).
