Japan’s metal recycling industry is supported by companies handling ferrous metals, copper, aluminum, precious metals, and other non-ferrous materials. Leading companies differ in their processing methods, recovery capabilities, collection networks, and environmental efforts.
Major Companies
- Sumitomo Metal Mining: Focuses on copper and other non-ferrous metal recovery, including recycling secondary copper materials.
- Mitsubishi Materials: Recovers copper, precious metals, and other valuable metals from industrial materials and scrap.
- DOWA Holdings: Involved in recycling and recovery of non-ferrous and precious metals from various waste materials.
- Hanwa: Handles aluminum, copper, zinc, lead, stainless steel, titanium, and other specialty metals.
- Matsuda Sangyo: Focuses strongly on precious-metal recycling, including gold, silver, platinum, and palladium.
- MERF: Specializes mainly in copper and copper-alloy recycling and produces recycled metal ingots.
