Circular Economy

TargetsToward a Circular Economy

Sumitomo Electric Group has long promoted the Reduce, Reuse, Recycle (3Rs) to reduce environmental impact, including minimizing defects at production sites, reducing waste generation, promoting internal reuse and the recovery of valuable materials, and reducing water consumption. Toward FY 2028, we will not only work to reduce and recycle waste generated during the production process, but also promote the use of recycled materials in our raw materials. Furthermore, Sumitomo Electric Group will now design products and services with recycling and reuse as fundamental considerations from the outset stage. This approach aims to minimize the use and consumption of new resources, maximize added value through efficient resource utilization, and ultimately realize a circular economy.

Major InitiativesPromoting Raw Material Recycling

Promoting the recycling of copper, our primary raw material, and rare metals, which are limited resources

After providing products to customers, the recovery of resources from used products plays a significant role in building a circular economy. Sumitomo Electric Group collects used electric wires and cables, optical fiber cables, and cemented carbide cutting inserts, recycling them as raw materials for new products.

Copper Recycling

Sumitomo Electric Group dismantles used electric power and communication cables at its affiliate Sumiden Material Processing Co., Ltd. and recycles the recovered copper using a copper smelting furnace known as a Tilting Reverberatory Furnace owned by our company.
