Business
Taiwan Steel Union Co., Ltd. (6581:TT) manufactures and sells crude zinc oxide recovered from electric arc furnace (EAF) dust using Waelz kiln high-temperature smelting technology; produces recycled aggregates including rotary kiln slag, stabilized reducing slag, and oxidizing slag; offers non-structural concrete and controlled low-strength materials (CLSM); and provides waste management services encompassing disposal, reuse, and remediation of general industrial waste, hazardous industrial waste such as EAF bag house dust, heavy metal-contaminated soil, zinc-containing sludges, incinerator fly ash, and organic biomass wastes. The company, founded in 1984 and headquartered in Changhua County, Taiwan, operates primarily in the commodity chemicals and waste management industries, distributing products domestically and to overseas markets including zinc smelters and chemical plants for further processing into high-purity zinc ingots or zinc oxide used in galvanizing, tire, and rubber sectors. Through its wholly owned subsidiary Taiwan Steel Resource Co., Ltd., it stabilizes EAF slags via autoclave technology for construction aggregates and concrete mixes, achieving a zero-waste model. In December 2021, the company secured permits for 11 classes of hard-to-dispose resource industrial wastes, expanding operations in 2022 to include zinc wastes, sludges, fly ash, and biomass for diversified recycling; it reported earnings for the second quarter and six months ended June 30, 2025, reflecting ongoing financial performance amid stable market conditions.
