Euroquarz

What Euroquarz does

Euroquarz is a German specialty industrial minerals company founded in 1897 and headquartered in Dorsten, Germany. It quarries and processes quartz sand and gravel at multiple production sites across Germany (Dorsten, Laußnitz, Salzbergen, Ottendorf-Okrilla, Essen, Hünxe) and the Netherlands (Heerlen, Maastricht), and has operated continuously for more than 127 years. The firm has been a wholly owned subsidiary of Possehl-Gruppe — within the Possehl Spezialbau-Gruppe division — since 2009.

The company's product portfolio is organized in two layers: (1) certified quartz sand and gravel grades for construction chemicals, concrete, and industrial applications, qualified under EN 12620, EN 12904, EN 13139, DIN 4924 and DIN 19643; and (2) specialty branded lines including AQUAGRAN, AQUAZIT, AQUALIN, AQUARBO, AQUABOLT, and CHLORAMIN-EX filter media for water treatment, plus engineered custom mixtures (SILIMIX, FEUCHTMIX), colored quartz, abrasives, and sports sands. In-house quality control is supported by a new bending tensile/compression testing machine at Laußnitz, and the Salzbergen site carries CSC sustainability certification alongside ISO 9001, ISO 14001, and EMAS.

Euroquarz operates a B2B direct sales model, selling into water treatment utilities, construction chemicals producers, industrial manufacturers, sports/horticulture distributors, and the pet/aquarium trade, with products described as 'exported worldwide.' The firm employs approximately 145 people, runs a 16-person apprenticeship pipeline, and is privately held with no publicly disclosed revenue. Its certifications, owned raw material deposits, and proprietary branded filter media are its primary commercial differentiators.

Scale indicators5 records

Recent moves13 records

Expansion highlights4 records

Emerging players

• Landsvirkjun / global industrial abrasives peers: Specialty blasting media and decorative quartz producers (e.g., regional European players like Eurogrit, Wibo, and Colorit) competing in narrow abrasives, equestrian sand, and colored quartz niches (e.g., Euroquarz's COLORQUARZ/AQUACOLOR and KONTRASIL lines). Limited scale individually but collectively shape price discovery in decorative quartz sub-niches.

Broad incumbents

• Sibelco: Global industrial minerals group and former owner of Euroquarz's Dutch subsidiary SIGRANO (sold to Sibelco in exchange for German distribution rights). Operates worldwide in silica, nepheline, feldspars, and filter media — directly comparable product family and customers, but at vastly greater scale.
• Huber Engineered Materials: J.M. Huber division producing specialty minerals including ground silica, calcium carbonate, and engineered fillers for construction chemicals, coatings, and engineered stone — directly comparable to Euroquarz's SILIGRAN® filler offering for paints, adhesives, and dry mortars.
• U.S. Silica Holdings: Largest North American industrial sand producer with oilfield, glass, construction, and specialty filter product lines. Comparable in end markets (foundry, glass, water filtration, building products) though Euroquarz operates at materially smaller scale and only in Europe.
• Covia Holdings (formerly Fairmount Santrol / Unimin): Major North American producer of industrial silica sand, proppants, and specialty mineral products for glass, foundry, and filtration. Comparable product mix to Euroquarz's silica flour and aggregate lines, but operates as a multi-billion-dollar public industrial minerals platform.

Direct peers

• Calgon Carbon (Kuraray): World-leading producer of granular activated carbon (similar to Euroquarz's AQUARBO® line) for municipal drinking water, industrial process water, and air treatment. Tangential overlap with Euroquarz's water treatment filter media portfolio, particularly on the activated carbon and specialty filter coal side (AQUARBO®, AQUAZIT®, CHLORAMIN-EX®).
• Eurogrit: Netherlands-based producer of specialty quartz grit and abrasives with strong European footprint in blasting media and industrial mineral fractions. Comparable to Euroquarz's KONTRASIL abrasive line and overlap in foundry/sandblasting customers across Northwestern Europe.
• Quarzwerke GmbH: Frechen (Germany)-headquartered family-owned producer of industrial minerals including quartz sand, kaolin, feldspar, and specialty fillers. Closest direct competitor in German silica sand with overlapping industries (construction chemicals, glass, foundry, paints/coatings) and similar product portfolio.

Regional players

• Quarzwerke Austria (Perlmooser Zement / Asamer family group): Austrian industrial minerals group with quartz sand, sand and gravel, and natural stone operations serving Central European construction chemicals, water treatment, and industrial customers. Comparable vertically integrated quarry-to-customer model, though primarily serving Austrian and Eastern European markets rather than Germany/Netherlands.

Others

• Possehl Spezialbau-Gruppe (sister operations): Parent construction services group that owns Euroquarz and operates complementary specialty construction and structural rehabilitation businesses across Germany. Adjacent rather than competitive, but represents the strategic ecosystem for cross-selling raw materials and dry mortars into specialty construction projects.
