Rheinische Baustoffwerke

What Rheinische Baustoffwerke does

Rheinische Baustoffwerke GmbH (RBS) is a German sand and gravel producer and certified mineral-construction-waste disposal operator headquartered in Grevenbroich-Frimmersdorf, North Rhine-Westphalia. Founded in 1997 and operating as a wholly-owned subsidiary of RWE Aktiengesellschaft, the company extracts, washes, crushes, and sells aggregates from open-pit sites across the Rheinland region — including locations at Garzweiler, Dormagen-Straberg, Hürth/Ville, Kaarst, Wanlo, Erkelenz, Buir, Gymnich, and others. Its customer base consists of construction firms, concrete and asphalt manufacturers, road builders, civil-engineering contractors, municipalities, and specialty buyers (sports surfaces, glass/ceramics, filtration), plus waste-disposal clients using its certified Entsorgungsfachbetrieb acceptance sites at Hürth/Ville and additional Z0-class sites.

The company offers three integrated product lines: (1) washed, unwashed, and quartz sands and gravels in standard and custom grain sizes for construction, concrete, and asphalt applications; (2) specialty products including beach-volleyball sand, riding-surface sand, drainage and lawn-care layers, and engineered filter substrates compliant with BN 918062 and TL-Gestein; and (3) certified mineral waste acceptance and recycling services handling LAGA Z0 and EBV classes up to BM-F3 and RC3. Operations are supported by an RFID-based loading- and access-card system (valid across RBS sites and at partner Siep, Straberg Kies, and Davids facilities), electronic weighbridges for transaction processing, and ongoing internal and external quality monitoring.

RBS generates revenue through three streams: per-ton sales of aggregates (one-time transaction), waste-disposal fees for accepted mineral construction waste, and freight/logistics services for delivery to customer sites. Pricing follows unit (per-tonne) rates that are not publicly disclosed; quotes are obtained via direct contact with the sales team. The company is managed by Geschäftsführer Michael Hennemann and Dr. Markus Osburg, with Carsten Simme heading overall sales and regional Betriebsleitung overseeing northern, central, and southern operations. The customer portal is hosted on the rbsw.rwe.com domain, reinforcing the operational integration with parent RWE. Kieswerk Kaarst GmbH & Co. KG operates as a wholly-owned adjacent subsidiary under shared management and joint ISO 14001 and ISO 50001 certifications.

Expansion highlights5 records

Broad incumbents

• Heidelberg Materials AG: One of the world's largest building materials groups with extensive aggregates, cement, and ready-mixed concrete operations across Germany. Directly comparable as an upstream aggregate supplier serving the same concrete, asphalt, and construction end-markets as RBS.
• Holcim Deutschland: German subsidiary of global building materials group Holcim, producing aggregates, cement, and concrete. Operates quarrying and aggregate processing capacity in Germany that competes with RBS for the same concrete and asphalt customers.
• K+S AG: German mining company producing industrial minerals, salts, and aggregates with significant extraction and processing operations. Comparable as a large German operator of mineral extraction assets serving construction and industrial customers.

Direct peers

• Dyckerhoff GmbH: German cement and aggregates producer with extensive quarrying and concrete operations across Germany. Comparable as a mid-size German supplier of construction aggregates serving overlapping customer segments in concrete and infrastructure.
• Basalt AG: German quarry operator extracting hard rock, sand, gravel, and limestone for construction and infrastructure. Direct peer in regional aggregate extraction and processing with comparable end-markets in concrete, asphalt, and civil engineering.

Regional players

• Hartsteinwerke Bayern (Mitteldeutsche Hartstein- und Baustoffindustrie): Quarry operator in southern Germany producing crushed stone, sand, and gravel for construction. Comparable business model and product mix but operates in a different geography, limiting direct head-to-head competition with RBS in the Rhineland.
• Franken-Schotter GmbH & Co. KG: Mid-sized German family-owned quarry group producing sand, gravel, and crushed stone in Bavaria and northern Bavaria. Comparable regional aggregate business model with overlapping specialty products (filter gravel, sports surfaces, concrete aggregates).
• Brenner Baustoffe GmbH & Co. KG: German regional supplier of sand, gravel, and construction materials with multiple sites in Baden-Württemberg. Comparable as a mid-size regional aggregate producer serving concrete, asphalt, and construction customers.
• Kies- und Sandwerk Hainichen GmbH: Mid-sized German sand and gravel producer operating quarries in Saxony. Comparable regional extraction and processing model, though geographically distinct from RBS's Rhineland footprint.

Emerging players

• Remex Mineralstoff GmbH: German specialist in mineral construction waste recycling and secondary aggregates. Comparable business line to RBS's waste acceptance (Verwertung) operations, increasingly relevant as German circular construction mandates expand.
