RUZ Minerals

What RUZ Minerals does

RUZ Mineralik GmbH, headquartered in Heilbronn, Germany, is a specialized recycling company that converts mineral construction waste, demolition rubble, and used rail ballast into certified secondary construction materials. Founded in 2012 as a spin-off from RUZ GmbH and operating under SER Sanierung im Erd- und Rückbau GmbH, RUZ Mineralik became a subsidiary of Heidelberg Materials in February 2023 when Heidelberg acquired the SER Group. The company's core technology consists of multi-stage wet processing lines — including rail-ballast washing, crushing, screening, and conditioning plants — co-located at five sites across the Heilbronn area (Lichtenbergerstraße, Benzstraße, Dieselstraße, Austraße), with a rail siding that enables inbound logistics via rail, truck, and ship.

The product portfolio spans RC-Gleisschotter (Q1-certified recycled rail ballast supplied to Deutsche Bahn under a 100,000 tonnes/year framework contract running since 2007), a full range of RC aggregates (RC-Splitt 2/8, 8/16, 16/32, RC-Gabionensteine, RC-Schottertragschicht, Sand 0/2), silo-produced mine backfill materials (Versatzbaustoffe) for underground mining, and two specialty precast sub-brands: the varioWand modular wall system and the Biosphärenstein biodiversity habitat stones. All products are certified and quality-monitored by external bodies (QRB, Institut Dr. Haag, GfB Baustoffprüfstelle) and the company operates as a certified Entsorgungsfachbetrieb. Differentiators cited include up to 80% CO2 savings versus primary materials for rail applications and 3.5x climate-friendliness versus primary aggregates.

RUZ generates revenue through per-tonne disposal/transaction fees for mineral waste processing, direct sales of recycled construction products via field sales (anchor contracts with Deutsche Bahn, REWE Group, Volksbank Heilbronn, C&A, Stadtbahn Neckarsulm, Bildungscampus Heilbronn) and a separate e-commerce web shop for smaller RC orders, plus specialty precast product sales. GTM is a hybrid of enterprise field sales for major framework contracts, public tenders for municipal infrastructure projects, and trade-fair/event-driven customer acquisition. The company is recognized with the Deutsche Bahn Supplier Predicate (Environment category, 2020/2021), the "100 Betriebe für Ressourceneffizienz" award (2022), and climate-neutral certification (2022).
