SG Completes Russian Patent Registration for Steelmaking Slag Asphalt Manufacturing Technology

Asphalt specialist company SG has completed the registration of a Russian patent for its eco-friendly asphalt manufacturing technology based on steelmaking slag.

On September 4, SG announced the completion of its Russian patent registration for the "method of manufacturing steelmaking slag aggregate and steelmaking slag asphalt concrete mixture." The patent was filed in April 2025 and will be valid for 20 years from the filing date.

Russia is one of the world's leading steel producers, with the steel industry concentrated in the Far East regions, including Primorsky Krai and Vladivostok, as well as major iron ore production sites. Accordingly, there is a high potential for utilizing technologies that both reduce the burden of disposing of slag generated during the steelmaking process and recycle it in an eco-friendly way.

SG's Eco Steel Asphalt Concrete is a high-durability eco-friendly asphalt paving material that uses steelmaking slag, generated during the steel production process, as a substitute for natural aggregates. By recycling industrial by-products as circulating resources, it reduces the use of natural resources and the burden of slag disposal, while providing superior durability and pavement performance compared to general asphalt concrete.

An SG official stated, "This Russian patent registration is significant in that it secures overseas intellectual property rights for our core Eco Steel Asphalt Concrete manufacturing technology." The official added, "Based on our proven technology and construction experience in Korea, we plan to continuously expand our patent portfolio in major overseas markets such as Indonesia and India, while further strengthening our foundation for entering the global eco-friendly road infrastructure market."
