Korea Zinc Inc., the world’s largest lead and zinc smelter, has gained fresh validation for its circular-metals strategy after an executive at its recycling subsidiary Steel Cycle Corp. has received a national climate award for advances in waste-to-resource processing.

Steel Cycle Vice Chairman Choi Min-seok was awarded the Minister of Climate Change Award for contributions to industrial decarbonization, marking the latest government recognition of the company’s rotary hearth furnace (RHF) technology, the company said Friday.

RHF processing extracts zinc from steelmaking dust and other iron-bearing waste streams, producing secondary feedstock that reduces both reliance on mined ore and the emissions associated with extraction.

It is the second government commendation for Steel Cycle in as many years, following a 2024 award from the Ministry of Trade, Industry and Energy, the company added.
