What Nedmag does
Nedmag B.V. is a privately held Dutch industrial minerals producer founded in 1972 and headquartered at Billitonweg 1, Veendam, with two adjacent Veendam sites — the Nedmagweg mining location and the Billitonweg processing complex — and approximately 150 employees. Its core activity is extracting high-purity bischofite magnesium chloride from Zechstein Sea deposits at depths of 1,500–2,000 metres and converting it into Dead Burned Magnesia (the branded Nedmag99 grade at ~99% MgO), calcium chloride, magnesium hydroxide and magnesium oxide. The upstream deposit is described as unique in the world and was discovered during 1972 exploratory gas drilling; commercial extraction began in 1981. Magnesium is recognised by the EU as a Critical Raw Material, positioning Nedmag as one of the few non-Russian, non-Chinese producers.
The company serves B2B customers across eight verticals: refractories (steel and cement kilns), environment (wastewater, flue gas, marine scrubbers), food and health (sodium reduction via the Novasal sub-brand), agriculture (manure enrichment via Farmin-G), energy (drilling fluids, future battery applications), safety (winter road maintenance), pulp and paper (sustainable bleaching), and industry. Pricing is quote-based with no public list, delivered on multi-year contracts in bulk, 1,000 kg big bags and 25 kg paper bags. Go-to-market is sales-led through three dedicated sales managers and customer service, supplemented by global channel partners — TIMAB Magnesium and Terresis for marine scrubbers, Farmin BV for Dutch agriculture, and Lhoist as both shareholder and dolime supplier via direct rail.
The business model is industrial commodity-plus-specialty sales of magnesium-based products to enterprise and government buyers, augmented by a recently built consumer/B2B food sub-brand (Novasal/Pure Health & Earth) targeting sodium reduction. Profitability is reinforced by the company’s certifications (ISO 9001, ISO 14001, FSSC 22000, ISO 22000, GMP+, Kiwa, Kosher, Halal, EcoVadis Committed) and its sustainability program, which already delivers 10–15% natural gas reduction via Bio-Energy Veendam green gas and is on a roadmap to full fossil-fuel independence by 2035 through hydrogen integration with DNV GL and Gasunie. Revenue is not publicly disclosed; two private shareholders — Lhoist and NOM — anchor the ownership structure.

Nedmag product offering
Product offeringCore offering
Nedmag extracts high-purity bischofite magnesium chloride from Zechstein Sea deposits 1,600-2,000 meters beneath Veendam, Netherlands. The company processes this raw material into four core industrial mineral products: calcium chloride, magnesium chloride, magnesium hydroxide, and magnesium oxide (Dead Burned Magnesia/Nedmag99). Products serve refractory, environmental, food, agricultural, energy, and winter road maintenance applications globally.
Product overview
Nedmag operates two locations in the northern Netherlands: a mining site extracting high-purity magnesium chloride from 1,600 metres beneath the former Zechstein Sea, and a production site manufacturing Dead Burned Magnesia (DBM), calcium chloride, and magnesium hydroxide. The product portfolio centers on four core industrial mineral products (calcium chloride, magnesium chloride, magnesium hydroxide, and magnesium oxide/DBM) sold primarily to B2B industrial customers across refractories, environmental, food, agriculture, and energy sectors. In 2025, Nedmag launched the Novasal sub-brand — a consumer-facing magnesium salt product line for sodium reduction in food — comprising Novasal Pure (direct salt replacement) and Novasal Blend (30% sodium reduction blend). Nedmag also offers MH53S Mare, a specialty magnesium hydroxide product for marine scrubbers. The company employs approximately 150 people at its Veendam operations.

Nedmag competitors and assessment
Company assessmentBroad incumbents
- Compass Minerals: US-listed producer of salt, magnesium chloride, and sulfate of potash serving highway de-icing, agriculture, and industrial customers. Directly comparable to Nedmag's calcium chloride and magnesium chloride product lines in winter road maintenance and agricultural applications.
- ICL Group: Israeli-listed specialty fertilizers and minerals company operating Dead Sea Works, a major global magnesium chloride producer. Comparable in magnesium salt extraction from natural brine, with overlapping applications in agriculture, water treatment, and flame retardants.
- Martin Marietta Materials: US-listed producer of aggregates and heavy building materials with a magnesia-based products division. Comparable as a public-market industrial mineral conglomerate with high-purity specialty applications, providing a benchmark for valuation and capital allocation in the sector.
- Imerys: French-listed global specialty minerals company with operations across industrial minerals including magnesium-related products. Comparable as a broad industrial mineral miner/processor with similar multi-vertical applications and an established research collaboration with Nedmag in pulp bleaching.
- RHI Magnesita: Global leader in refractory products and a key buyer of high-purity DBM. While RHI Magnesita is a downstream customer rather than a competitor, it is a comparable industrial peer given shared exposure to the refractory value chain and DBM demand drivers.
- K+S AG: German-listed potash and salt mining company producing magnesium chloride and related products for de-icing, agriculture, and industrial markets. Comparable peer in mined magnesium salts serving the same European winter road maintenance and agricultural customer base.
Direct peers
- Lhoist: Belgian family-owned global leader in lime, dolime, and technical lime applications with ~6,000 employees. Lhoist is both a Nedmag shareholder and a key raw-material supplier (dolime via rail to Veendam); it operates in the same industrial minerals value chain with overlapping mining and processing capabilities.
- Premier Magnesia: US-based producer of magnesium oxide, magnesium hydroxide, and related magnesia products serving environmental, industrial, and agricultural markets. Directly comparable to Nedmag across magnesium hydroxide and MgO product lines, though without Nedmag's unique Zechstein bischofite source.
- Mag Specialties: US producer of magnesium hydroxide slurries, magnesium oxide, and magnesium carbonate for environmental, pharma, and industrial uses. Directly comparable in stabilized magnesium hydroxide suspension technology, a product area where Nedmag holds a 'reference product' market position.
- TIMAB Magnesium: European magnesium hydroxide and magnesia producer partnered with Nedmag on MH53S Mare since 2018. TIMAB handles global distribution of marine scrubber alkali while sharing technical expertise with Nedmag, making it both a partner and a direct comp in magnesium hydroxide.
