Japan's Silent Trash Crisis — Fires, Staff Shortages, and the AI Revolution in Waste Management

Japan's waste management system is in quiet crisis: aging incinerators, a nationwide sanitation worker shortage, and roughly 8,500 fires a year triggered by lithium-ion batteries lurking in everyday gadgets. In this episode, Haru and Sakura meet inside a municipal incineration plant's control room — where analog gauges from the 1990s share wall space with AI detection screens — to unpack Japan's silent trash emergency. They cover how an AI sorting chatbot on the LINE app offers partial relief, why Tokyo's 23 wards are trapped in a coordination standoff over garbage fees, and how one Saga City project is converting incineration exhaust into liquid CO₂ for sale. From rare earth recycling gaps to aging infrastructure blind spots, this episode explores how Japan's waste sector is being forced to reinvent itself — and whether trash can become the country's next resource frontier.
