Rocklink Gmbh

What Rocklink Gmbh does

Rocklink GmbH is a privately held German limited liability company headquartered in Düsseldorf, operating as part of the Petromine Group founded approximately 30 years ago (~1996). The company runs two divisions: Rare Metals Recycling and Fine Chemicals & Metals. Rare Metals Recycling collects, pre-treats, and trades rare earth magnet scrap, lithium-ion batteries, spent catalysts, metal concentrates, and electric motors through wholly-owned subsidiaries in Germany, India, the Philippines, Malaysia, Hong Kong, and China, processing over 20,000 tons per year using proprietary thermal-mechanical recycling technology achieving over 98% recycling efficiency. Fine Chemicals & Metals distributes rare earth compounds (covering all 17 rare earth elements plus yttrium) along with nickel, cobalt, manganese, and lithium compounds, acting as exclusive European sales representative for Shenghe Resources Holding.

The company serves enterprise customers across battery cell manufacturing, permanent magnet production, non-ferrous metallurgy, wind power, automotive, industrial automation, medical equipment, and petrochemical sectors through direct B2B sales. Around 650 employees support operations worldwide. Rocklink's go-to-market is direct enterprise sales with pricing on request; revenue is generated via recycled materials sales margins and distribution commissions. Differentiators include the Magcycle box-in-the-box magnet scrap collection system, a proprietary database of 3,000+ rare earth material flow data points, ISO 14021:2016 100% Recycled Content certified outputs for Nd/Pr/Dy/Tb, and closed-loop traceability from scrap to finished product. The company is a founding board member of the Global Rare Earth Association (REIA) and a member of the European Raw Material Alliance (ERMA). In 2025, Rocklink partnered with BatX Energies to establish India's first fully integrated rare earth magnet recycling facility under India's National Critical Minerals Mission.

Revenue model

1. Rare Metals Recycling: Collection, processing, and trading of rare earth magnet and lithium ion battery raw materials from waste streams. The company collects, pre-treats and trades materials globally through its network of subsidiaries, generating revenue through the purchase and sale of recycled rare earths, nickel, cobalt, and lithium from industrial waste, post-consumer batteries, and e-waste. Over 20,000 tons per year processed.
2. Fine Metals & Chemicals Distribution: Distribution of rare earth compounds, nickel, cobalt, manganese and lithium compounds and metals manufactured by affiliated companies and exclusive agency manufacturers. Products are manufactured exclusively by affiliated companies as well as by selected manufacturers represented as exclusive agent. Revenue earned through product sales margins.
3. Rare earth magnet recycling facility partnership: Through partnership with BatX Energies, Rocklink participates in establishing India's first fully integrated rare earth magnet recycling facility, generating recycling revenue opportunity projected at ₹250–300 crore in India over five years.

Direct peers

• SungEel HiTech: South Korea's largest lithium-ion battery recycler with operations across Korea, Europe and Southeast Asia, producing black mass and battery-grade metal compounds. Comparable to Rocklink's battery recycling arm in scale, technology (pyro-hydrometallurgy), and Asian footprint.
• Li-Cycle: Canadian lithium-ion battery recycler using a proprietary wet-mechanical (spoke-and-hub) process to produce black mass from end-of-life batteries. Closely comparable to Rocklink's thermal-mechanical battery recycling route, though Li-Cycle is publicly listed, focused on Li-ion feedstocks only, and does not cover rare earth magnets.
• Redwood Materials: US-based battery recycling and cathode active material producer founded by former Tesla CTO JB Straubel, backed by Amazon, T. Rowe Price and Ford. Direct peer to Rocklink's battery recycling business with a focus on closed-loop supply of critical battery materials (Li, Co, Ni, Cu) to North American cell makers.
• Cyclic Materials: Canadian rare earth and battery metal recycler using hydrometallurgy to recover magnet-grade rare earth oxides (Nd, Pr, Dy, Tb). Direct competitor in Rocklink's core rare earth magnet recycling niche, particularly for NdFeB feedstock from end-of-life magnets and e-waste.

Regional players

• Hyundai/ SungEel Geocycle JV: Asia-based partnerships (e.g., SungEel with Korean automakers) building regional battery recycling capacity close to gigafactory hubs. Comparable as competing regional recyclers addressing similar Korean/Japanese OEM feedstock; an indirect peer due to Rocklink's Southeast Asian footprint serving similar end markets.

Broad incumbents

• Umicore: Belgian global materials technology and recycling group with a dedicated battery materials and precious metals recycling business. Comparable to Rocklink as a large-scale, multi-jurisdictional recycler of complex industrial and battery feedstocks, but operates across a much broader portfolio (catalysis, energy materials) than Rocklink's rare-earth-focused niche.
• Solvay: Belgian chemicals group with a dedicated rare earths business (La Rochelle separation plant) serving permanent magnet and catalyst markets globally. Comparable to Rocklink's Fine Chemicals & Metals arm as a European rare earth compound supplier, though Solvay is much larger and historically primary-mineral-based rather than recycling-focused.
• Fortum Battery Recycling: Division of Finnish utility Fortum operating a hydrometallurgical battery recycling plant in Harjavalta with co-located BASF black mass processing. Comparable as a European-headquartered, industrial-scale battery recycler serving OEMs, but part of a much larger utility group and not active in rare earth magnets.

Emerging players

• HyProMag: UK-based rare earth magnet recycler commercialising the HPMS (Hydrogen Processing of Magnet Scrap) process from the University of Birmingham's ReProMag research project (in which Rocklink also participates). Direct niche competitor in NdFeB magnet-to-magnet recycling using an alternative hydrogen decrepitation route.
• Hydrovolt: Joint venture between Norsk Hydro and Northvolt recycling EV batteries at a flagship plant in Fredrikstad, Norway. Comparable to Rocklink's battery recycling business for European OEM feedstocks; narrower product scope (no rare earths) and tied to Northvolt's production scrap pipeline.
