On April 9, 2026, the Japanese Cabinet officially approved the latest amendment to the Waste Disposal and Public Cleansing Act (commonly known as the "Waste Cleansing Act"). The core of the amendment is to upgrade metal recycling operations from a notification system to a permit system, and to impose a new obligation requiring confirmation from the Minister of the Environment for scrap metal exports.

[SMM Survey: Global Magnesium Supply Landscape Undergoes Accelerated Restructuring with Simultaneous Breakthroughs in Australian Waste Residue Magnesium Extraction and EU Strategic Projects] Australia's waste residue magnesium extraction project achieved a key breakthrough, Greenland's Molli Hill received EU strategic certification, and Romania launched dual projects. The global magnesium supply chain is undergoing accelerated restructuring, with trends toward green and regional development emerging.

Against the backdrop of global sustainable development, the recycled metal industry is gaining importance. As the conflict between resource shortages and growing demand intensifies, countries are increasing policy and technology investment in this sector to promote a green economy. Japan, as a key recycled resource hub in Asia, possesses advanced technologies (such as aluminum dross processing) and closed-loop recycling models, and plans to expand the scale of e-waste recycling. However, its domestic capacity to absorb secondary aluminum is limited, necessitating expansion into markets outside China; secondary copper capacity is also expanding simultaneously. Sino-US trade issues have also highlighted the necessity of supply chain stability. Against this backdrop, with the theme "Voice of Low Carbon, Global Resonance," the will be held in Tokyo, Japan, on May 11–12, 2026. At this conference, will participate as an attending company, with Chairman Javier Riba Mas and Asia Manager Jose Maria Lozoya Fontanals in attendance. Global sustainability highlights the importance of the recycled metal sector. With resource shortages intensifying, countries (notably Japan, Asia's recycling hub) are advancing tech and policies. Japan aims to expand e-waste recycling but needs markets outside China for secondary aluminum; secondary copper output is also growing. Sino-US trade tensions further emphasize supply chain stability. 2026 SMM (3rd) Global Renewable Metal Industry Chain Summit (Theme: Voice of Low Carbon, Global Resonance ) is scheduled for May 11–12, 2026 , in Tokyo, Japan . At this conference, RIBA FARRE will attend, with Chairman Javier Riba Mas and Asia Manager Jose Maria Lozoya Fontanals in attendance.
