Business Areas

• Bioenergy: We produce eco-friendly biofuels such as biodiesel, bio-heavy oil, and bio-marine oil using various waste resources like waste cooking oil and vegetable/animal oils. In particular, we are focusing on producing raw materials for next-generation biofuels, Hydrotreated Vegetable Oil (HVO) and Sustainable Aviation Fuel (SAF).
• Battery Recycling: We collect waste lead-acid batteries to manufacture recycled lead (metallic lead) and alloy lead, and produce copper and copper alloys. We are also expanding our scope to the lithium-ion battery (LIB) recycling business, establishing vertical integration from black mass extraction to precursors and cathode materials.
• Plastic Recycling: We manufacture and sell PVC stabilizers and LDH, which are key additives used in processed products of the petrochemical industry. Based on high-purity sorting technology, we are strengthening our PCR (Post-Consumer Recycled) plastic business and entering the high-value plastic market for automotive and home appliances.

Products

• Biodiesel and Bio-heavy oil: Eco-friendly transportation fuels produced from waste cooking oil and vegetable/animal oils, used for vehicles, power generation, and ships. We have secured the largest production capacity and market share in Korea.
• HVO Pretreatment Raw Material and SAF: Hydrotreated Vegetable Oil (HVO) pretreatment raw material is a high-purity raw material used for producing next-generation biodiesel and Sustainable Aviation Fuel (SAF). It is produced at Pyeongtaek Plant 1 through the HVO PTU facility and supplied to global oil companies.
• PVC Stabilizer and PCR Plastic: PVC stabilizer is a key additive used in processed products of the petrochemical industry. PCR plastic is a high-value recycled plastic made by recycling discarded plastic after use, produced through high-purity sorting technology.
