Summary
Japan faces mounting challenges in solar panel recycling as disposal volumes are set to surge in the 2030s. A government bill mandating panel reuse was delayed due to cost allocation disputes, with owners and manufacturers debating responsibility. Toxic materials in panels pose environmental risks, and improper disposal could harm public health. Solar energy’s rapid growth, driven by the 2012 FIT system, has outpaced recycling infrastructure. Experts warn that without urgent legal frameworks, annual waste could reach 500,000 tons by the 2040s. The ruling party plans to reintroduce the bill in the autumn session to address these pressing issues.
