Performance in Environmental Improvement

HYUNDAI STEEL manages air and water contaminating substances created in the production process more strictly than required by the legal standards and makes best efforts to minimize environmental pollution with maximized recycling of water and by-products.

Air Quality

HYUNDAI STEEL sets company emission standards stricter than legal standards by applying the BAT (Best Available Technology) to each contaminant to effectively manage dust, sulfur oxides (Sox), and nitrogen oxides (Nox) created in the production process.

By-Products

By-products created from each factory of HYUNDAI STEEL are steel slags, steel dusts, spent refractory, and sludge, with steel slag taking up about 70 percent of this amount. HYUNDAI STEEL reuses approximately 90 percent of by-products as refractory cement, bricks and aggregates for filling construction/landfills/roads.

2014 : Amount of byproducts 10,508, By-product Recycling Rate 98.1% / 2015 : Amount of byproducts 10,318, By-product Recycling Rate 98,7% / 2016 : Amount of byproducts 10,394, By-product Recycling Rate 99.1% / 2017 : Amount of byproducts 10,605, By-product Recycling Rate 98.6% / 2018 : Amount of byproducts 10,663, By-product Recycling Rate 97.5%

Water and Water Quality Management

Minimum 98% of the water used in the production process is reused through filtering and sedimentation process in the wastewater treatment facility installed at each factory. Also, before it is discharged, the wastewater created in the production process is treated with the optimum method at the wastewater treatment facility operated at each factory, which treats contaminants such as suspended solid (SS), chemical oxygen demand (COD), and biological oxygen demand (BOD) more strictly than required by legal standards.
