Hyosung Advanced Materials Inc.

-Certification for Bio-Carbon Fiber Production System Utilizing Rapeseed Oil and Waste Cooking Oil

SEOUL, South Korea, Sept. 9, 2025 /PRNewswire/ -- HS Hyosung Advanced Materials, a global leader in carbon fiber technologies, announced that it has earned ISCC PLUS (International Sustainability & Carbon Certification PLUS), a widely recognized standard for sustainable materials and supply chain transparency. The certification establishes a validated framework for ensuring sustainability across the company's carbon fiber production process and supply chain, incorporating both plant-based inputs and recycled raw materials.

ISCC PLUS is an international standard certification that verifies the traceability and sustainability of bio-based and recycled feedstocks. It is regarded as a key benchmark by global manufacturers and institutions when assessing ESG practices. Achieving the certification requires independent verification across the full lifecycle—from raw material sourcing through production and distribution—and is broadly recognized for its rigor and credibility in international markets.

The certified bio-AN carbon fiber production process at HS Hyosung Advanced Materials demonstrates strong commercial potential, as it aligns closely with established chemical manufacturing methods. Independent analysis confirms that carbon fibers produced from bio-acrylonitrile deliver mechanical performance equivalent to conventional products. Importantly, acrylonitrile (AN), the precursor to bio-acrylonitrile, is produced using bio-naphtha derived from renewable and recycled sources such as rapeseed oil and waste cooking oil—reducing carbon emissions across the value chain.

"Securing ISCC PLUS certification marks an important milestone toward building a fully sustainable production platform," said Jin Dal Lim, CEO of HS Hyosung Advanced Materials. "We are committed to advancing the next generation of low-carbon, bio-based materials and strengthening our leadership in sustainable solutions for the global market."

In addition to ISCC PLUS certification, HS Hyosung Advanced Materials recently received the Platinum Medal from EcoVadis, placing it among the top 1% of companies evaluated for supply chain ESG performance worldwide. The company also maintained an "A" rating in the CDP Supply Engagement Assessment (SEA), demonstrating its ongoing commitment to sustainability leadership and responsible growth across the value chain.

• Strategic raw material agreement supports the plan to triple eco-friendly steel tire cord sales by 2027
• Expands sustainable product portfolio to align with global tire manufacturers' low-carbon sourcing goals

SEOUL, South Korea, June 18, 2025 /PRNewswire/ -- HS HYOSUNG ADVANCED MATERIALS signed a memorandum of understanding (MOU) with Tata Steel (Thailand) on June 18th for the procurement of lower-carbon steel wire materials.

Under the agreement, HS HYOSUNG ADVANCED MATERIALS will secure a reliable supply of low-emission steel wire materials required for the production of steel tire cord. Tata Steel (Thailand), a subsidiary of India's Tata Group, uses electric arc furnace (EAF) technology to produce steel from recycled scrap metal. Compared to traditional blast furnace operations, EAF production achieves significantly higher energy efficiency and reduces carbon emissions by approximately 60%. By utilizing these materials as raw inputs, HS HYOSUNG ADVANCED MATERIALS can produce and supply eco-friendly steel tire cords with significantly reduced carbon footprints.

Given their higher margins compared to traditional steel products, eco-friendly steel tire cords are expected to strengthen the profitability and competitiveness of HS HYOSUNG ADVANCED MATERIALS' steel tire cord operations. 

"We are pleased to formalize this agreement, which ensures long-term access to environmentally responsible steel," said Nak Yang Seong, CEO of HS HYOSUNG ADVANCED MATERIALS. "This aligns with our strategy to support global tire makers in their shift toward sustainable materials."

Steel tire cords produced by HS HYOSUNG ADVANCED MATERIALS are crucial reinforcement materials that enhance tire durability and maintain shape stability. The importance of high-strength steel cords is growing alongside the expanding electric vehicle tire market. Furthermore, as demand for sustainable raw materials grows across developed markets, particularly in Europe, sales of eco-friendly steel tire cords are steadily rising. HS HYOSUNG ADVANCED MATERIALS aims to expand the sales share of its eco-friendly steel tire cord products from 5% in 2025 to 15% in 2027.

HS HYOSUNG ADVANCED MATERIALS' commitment to sustainability management was recognized last October when the company received the Platinum Medal from EcoVadis — the highest distinction awarded to the top 1% of over 130,000 companies across 180+ countries by the global supply chain ESG ratings provider. In December, the company was also added to the Dow Jones Sustainable Management Index (DJSI) Korea for the second consecutive year, one of global leading ESG benchmarks.
