DS Dansuk

What DS Dansuk does

DS Dansuk (DS단석, KOSPI: 017860) is a South Korean resource-circulation and clean-energy company operating across three integrated business segments: bioenergy, battery recycling, and plastic recycling. Founded in 1965 as Nobel Chemical Industry and rebranded at its 2023 KOSPI listing, the company processes waste streams — used cooking oil, spent lead-acid and lithium-ion batteries, and post-consumer plastics — into higher-value fuels, metals, and polymer additives. Core products include FAME biodiesel, bio-heavy oil, bio-marine fuel (ISO 8217 compliant), HVO pre-treated feedstock for Sustainable Aviation Fuel, LME-registered recycled lead (Pb ≥99.97%), lead and copper alloys, Black Mass (Ni 20-45%, Co 5-15%, Li 3-7%) from spent LIBs at the Gunsan facility's ~5,000 t/yr capacity, PVC heat stabilizers (lead-based and non-toxic), Hydrotalcite (LDH), and PCR plastic compounds (PP, ABS).\n\nThe company runs a B2B sales-led go-to-market with direct supply agreements to Korean power utilities (Korea Midland Power, Korea Southern Power) for RPS-mandated bio-heavy oil, to Korean oil refiners for RFS-mandated biodiesel blending, and to international SAF producers (Phillips 66, Cosmo Oil, S-Oil) and commodity traders (Trafigura, Kolmar) for export volumes. Revenue is transactional, commodity-priced per tonne or barrel, anchored by long-term regulatory mandates in Korea (RFS, RPS) and abroad (US EPA, EU ISCC, California LCFS, ISCC CORSIA for aviation). Distribution is supported by 5 domestic plants, 5 domestic subsidiaries (including DS PCR, DS Wooil Bio, HIVE), and 3 overseas subsidiaries in Malaysia, Pakistan, and China.\n\nMore recently, DS Dansuk has pursued forward-looking expansion into adjacent energy verticals — a January 2026 MOU with Nano Nuclear Energy to coordinate KRONOS Micro Modular Reactor deployment in South Korea, a June 2025 MOU with Narada on energy storage systems, and a June 2025 MOU with Jeollabuk-do Province for a Net-Zero Complex. These moves extend the company's mandate from waste valorization into distributed clean energy infrastructure. The company has been recognized with the Korean Government's US$300M Export Tower Award in 2024 (up from US$200M in 2022) and the Iron Tower Industry Medal in 2024, and joined the UN Global Compact in July 2024.

Revenue model

1. Bioenergy Products: Sale of bio-diesel, bio-heavy oil, bio-marine fuel, and HVO pre-treated feedstock. Biodiesel is sold domestically to oil refiners for mandatory RFS blending (0.5%–4.0% depending on year) and exported to the US (EPA-registered), EU (ISCC certified), and other markets. Bio-heavy oil is supplied to Korean power generation companies under RPS obligations. Bio-marine fuel is sold to shipping companies. HVO feedstock is sold to international SAF producers. Revenue model is transactional, volume-based (unit pricing per tonne/barrel).
2. Battery Recycling Products: Sale of recycled lead ingots (Pb 99.97% min, LME-registered), lead alloys (antimony, calcium), copper/copper alloys (C1100, C2680, C7060 grades), and Black Mass. Products are sold B2B to battery manufacturers, solar panel ribbon makers, solder alloy companies, wire/cable companies, transformers, shipbuilding, and LIB precursor manufacturers. Revenue model is transactional/commodity-priced per metric tonne.
3. Plastic Recycling Products: Sale of PVC composite stabilizers (lead-based and non-toxic), metal soap raw materials (Ca-St, Zn-St, Ba-St), Hydrotalcite (LDH), and PCR plastic compounds (PP, ABS). Sold to PVC processors, polyolefin compounders, spandex manufacturers, and plastic molders. Revenue model is transactional per tonne or per kg, with some customer-customized formulations.
4. Micro Modular Reactor (MMR) Localization Services: As local coordinator for Nano Nuclear Energy's KRONOS MMR deployment in South Korea, DS Dansuk provides site identification, supply chain localization, regulatory engagement, and institutional partnership services. Revenue model for this segment is still emerging as the partnership is in a non-binding MOU stage leading to project-specific agreements. Also encompasses ESS (Energy Storage System) business through the Narada MOU.
