"Seasonal Byproducts Recycled as Construction Materials" Hyundai Steel Low-Carbon Symposium

Co-hosted by the Slag Concrete Committee

[Asia Economy Reporter Choi Seoyoon] Hyundai Steel has partnered with the construction industry to expand the recycling of steelmaking by-products.

On the 14th, Hyundai Steel held the "Symposium on Low-Carbon Construction Material Technology Utilizing Steelmaking By-products" jointly with the Slag Concrete Committee under the Korean Concrete Institute at COEX in Gangnam-gu, Seoul.

The symposium was organized to introduce the current technology status of steelmaking by-product recycling and to provide companies with opportunities to actively participate in recycling.

The event was attended by over 200 people, including construction company officials who are actually using steelmaking by-products as construction materials, as well as major academic institutions and organizations.

Kim Hyungjin, Head of the Process Research Center at Hyundai Steel, said in his welcoming speech, "The demand for construction aggregates is increasing day by day, but natural aggregates are gradually being depleted. Recycling steelmaking by-products as construction materials is an essential element for resource circulation and carbon-neutral management, contributing to the realization of a sustainable society."

At the symposium, six organizations including Hyundai Steel, Korea Institute of Ceramic Engineering and Technology, POSCO Engineering & Construction, Korea Road Traffic Authority, Kongju National University, and Hyundai Engineering & Construction presented on the current technology status for expanding slag recycling.

Hyundai Steel, which operates steelworks, presented on the domestic slag generation and recycling status as well as predictions of slag changes according to carbon-neutral transition technologies in the steel industry. Construction companies introduced cement replacement technologies using recycled slag and actual application cases.

After the keynote presentations, Professor Lee Geoncheol of Korea National University of Transportation chaired a comprehensive discussion on diversifying the recycling of steelmaking by-products and reconsidering the carbon-neutral effects.
