KOREA ZINC

Korea Zinc (KZ) committed to renewable energy production and development, supplying renewable energy to other companies to support decarbonization efforts through Ark Energy located in Australia. As an initial step, they have signed a direct renewable energy power purchase agreement (PPA) with Telstra, Australia's largest telecommunications company. From 2025, when the Macintyre Wind Precinct is completed and operational, they will supply clean electricity equivalent to the annual electricity consumption of 80,000 Australian households over a 10-year period. KZ is also positioning the green hydrogen business as a major future growth engine, collaborating with SK E&S to establish a large-scale green hydrogen production complex in Ulsan. The facility plans to produce 20,000 tons of green hydrogen annually, utilizing renewable energy sources such as solar and wind power. They are also involved in the construction of a hydrogen fuel cell power plant utilizing green hydrogen. This power plant will generate electricity using green hydrogen as fuel, contributing to increasing energy self- sufficiency through an environmentally friendly power generation method that produces zero carbon emissions.

Korea Zinc (KZ) is strengthening its resource circulation business leveraging its existing non- ferrous metal smelting technology to recover metal resources from waste and byproducts. KZ is particularly focusing on recovering rare metals and precious metals by recycling electric vehicle battery waste, electronic waste, and spent catalysts, aiming to build a sustainable circular economy. Through the recycling of used electric vehicle batteries and ESS, KZ is recovering essential metals such as lithium, nickel, and cobalt—key resources in the expanding electric vehicle market. Additionally, through its e-waste processing business, KZ extracts precious metals such as gold, silver, and palladium from electronic waste from smartphones and PCs. KZ is simultaneously developing technology to extract high-value metals like platinum and rhodium from spent catalysts, enhancing the recycling of scarce resources. The resource recycling business aims to establish a circular economy for metal resources and lead the global resource circulation market as the waste generated from electric vehicle and electronic products increases. These efforts reflect KZ’s commitment to sustainable growth and environmental stewardship.

Korea Zinc (KZ) is expanding its secondary battery materials business using its 50 years of expertise in smelting technology. KZ is creating a comprehensive value chain encompassing nickel smelting, nickel sulfate, precursor production, electrolytic copper foil manufacturing, and waste battery recycling. To meet rising demand for electric vehicle batteries and energy storage systems (ESS), KZ is focusing on producing core materials, including precursors for nickel, lithium, and cobalt. Battery recycling is another priority, strengthening its market competitiveness while fostering a sustainable business mode KZ established KZAM, a precursor production company, in partnership with LG Chem, with the goal of producing 200,000 tons of precursors annually. Precursors are considered essential resources in the global electric vehicle battery market as core materials for secondary batteries. KZ is also expanding its nickel refining business to provide a stable supply of high-purity nickel, a key raw material for electric vehicle batteries, and is also entering the lithium business. In addition to refining lithium extracted from minerals, KZ is focusing on producing recycled lithium recovered from used batteries to strengthen its raw material supply chain. Through its battery recycling business, KZ recovers valuable resources such as lithium, nickel, and cobalt from used batteries, and reuses them to realize resource circulation while creating cost reduction effects. Through these efforts, KZ aims to fulfill its environmental responsibilities while maximizing economic value.
