DS Danseok’s New Patent: Revolutionizing Used Cooking Oil Recycling?

On September 18, 2025, DS Danseok secured a patent for an ‘Automated System for High-Purity Used Oil Recovery and Continuous Separation of Scrap Iron and Impurities from Used Oil Cans’. This robotic system automates the separation of used oil, iron, and impurities, featuring a hot oil spraying and hot air supply system to prevent oil solidification in winter, maximizing recovery efficiency.

Why This Patent Matters

This patent is expected to significantly impact DS Danseok’s bioenergy business, particularly biodiesel and Sustainable Aviation Fuel (SAF) production. Used cooking oil (UCO) is a key feedstock for both, making high-quality UCO acquisition crucial for competitive advantage.

What Does This Mean for DS Danseok’s Future?

  • Cost Reduction and Efficiency Gains: The automated system promises increased UCO recovery rates, streamlined processes, and reduced costs.
  • Enhanced Bioenergy Competitiveness: Securing high-quality UCO strengthens competitiveness in biodiesel and SAF production.
  • Strengthened ESG Initiatives: The patent reinforces DS Danseok’s image as an eco-conscious company committed to waste recycling.
  • Business Expansion Potential: The standardized modular system facilitates expansion of production facilities domestically and internationally.
