Copper Foil Division’s electrolytic copper foil containing 100% recycled copper has completed UL 2809 validation
By recycling copper power cable for use in the manufacturing of electrolytic copper foil, greatly reduce CO₂ emissions in the manufacturing process
Along with the introduction of renewable energy, manufacture electrolytic copper foil with low environmental burden

Furukawa Electric Co., Ltd. (Head Office: 2-6-4 Otemachi, Chiyoda-ku, Tokyo; President: Keiichi Kobayashi) completed third party validation based on UL 2809 ^(Note) in July for the electrolytic copper foil manufactured at the Copper Foil Division’s Imaichi East Plant (Nikko City, Tochigi Prefecture) and Furukawa Circuit Foil Taiwan Corporation (Douliu in Yunlin County, Taiwan; hereinafter “FCFT”).

(Note) UL 2809: Validation procedure set forth by the US-based UL Solutions for environmental declarations concerning recycled content.

Background

In 2021, we announced the Furukawa Electric Group Environmental Vision 2050 and set the goal of reducing greenhouse gas emissions throughout the value chain in order to contribute to the realization of a carbon free society. In particular, as part of the “recycling-based production activities”, we have worked to manufacture cable, copper products and plastic products that use recycled raw materials from used power cable, copper strips, copper wire and plastic. The Copper Foil Division is manufacturing high performance electrolytic copper foil for collector plates in lithium ion batteries equipped in electric vehicles and printed wiring boards used in telecommunications devices such as servers, routers, mobile phones and other mobile devices.

Details

We were already manufacturing electrolytic copper foil using recycled copper power cable, but given the increased demands for recycling and decarbonization in recent years, we independently declared that our main products are “manufactured using copper foil containing 100% recycled copper” in order to enable customers to feel confident about using our products. In July of this year, we completed UL Solutions' third party validation of this claim. Our copper foil products manufactured using recycled copper make it possible to greatly reduce CO₂ emissions compared to the use of electrolytic copper.

Introduction of renewable energy at the manufacturing plants

We have switched to substantial renewable energy for the electricity used at the Imaichi East Plant from April of this year, and we are currently manufacturing electrolytic copper foil with extremely low environmental burden. In the life cycle assessment (LCA) used to evaluate the environmental impact throughout the life of the product, our products contribute to reducing CO₂ emissions from procuring the raw materials to disposal or recycling of the product. We will further accelerate our efforts aimed at becoming carbon neutral and propose new value to customers by reducing CO₂ emissions throughout the value chain.
