Japan Solar Panel Recycling Mandate to enhance sustainability

Japan Solar Panel Recycling is set to introduce a groundbreaking recycling mandate for solar panels to tackle the surge in decommissioned panels expected around the mid-2030s.

This initiative is a critical part of Japan’s strategy to boost sustainability and manage waste from the expanding solar industry. The proposed legislation will classify used solar panels as industrial waste, mandating their recycling similar to the EU’s WEEE directive.

This move is expected to reach parliament next year, with the Environment Ministry estimating that 500,000 to 800,000 tons of solar panel waste will need to be managed annually by the mid-2030s.

Current Recycling Challenges and Solutions


At the same time, rules dictate that nearly all solar panels eventually end up in landfills since a recycling requirement does not currently exist. In the new policy, the government plans to change this with recycling fees on owners of solar panels, following standards already set for automobiles and household electronics.

They also include the Environment Ministry which is striving for expanding capacities in recycling centers and the development of cost-effective recycling technologies. Japan Solar Panel Recycling truly matters.

Impact on the Solar Industry and Environmental Goals


This policy is key because it will enable Japan to halve its emissions by 2030 and achieve carbon neutrality by 2050. Reduction in waste from landfills and the use of materials recovered from decommissioned panels will facilitate the reuse of resources.

The policy promises to deliver vast environmental benefits: reduced greenhouse gas emissions and minimized use of landfills.

The glass, silicon and aluminum materials can be reused, making solar panels cheaper in the long run to manufacture and dispose of. At the center of these environmental and economic strategies stands Japan Solar Panel Recycling.

Japan needs international co‑operation with other multinational solar panel-makers – including, perhaps, the Chinese – to ensure that the mandate is successful.

Technological breakthroughs, such as the pilot project developed by AGC and Tokuyama to produce float glass from recycled solar panels, means that the industry is well-poised to develop more environmentally friendly recycling solutions. Japan Solar Panel Recycling is poised to benefit from foreign partnerships and innovation.

Financial Implications and Operator Responsibilities


The Environment Ministry has pointed to potential shortfalls in capacity at recycling centres as one of the main challenges, and Japan intends to increase the capacity of current facilities and develop better and cheaper technologies for recycling solar panels.

Research into these technologies is being carried out by the Ministry of Economy, Trade and Industry, ostensibly to lower costs and to ensure that the 2034 mandate is sustainable in the long term.

When that same agency surveyed solar power operators in 2019, they discovered that fewer than 20 per cent had put money aside to dispose of panels. That same year, a new mandate promised that operators would be required to set money aside for that purpose starting in 2022.


Solar Industry Growth and Challenges


Power from the solar panels supplies 65 per cent of Japan’s renewable energy output, excluding hydropower (compared with around 30 per cent of the total for the EU, the US and China). At some panel sites, buyback agreements have resulted in an oversupply of electricity.

As a consequence, dozens of solar panel farms had to be shut down or their output cut back during summer 2013 because there was not enough demand. Side effects of the rapid growth spurt include deforestation and landslides due to badly planned solar farms.

The Japan Solar Panel Recycling mandate is one small part of a larger effort to rectify such problems and create more sustainable industry practices.

In March, AGC and Tokuyama, two Japanese companies, won acclaim for having successfully experimented with a new type of recycling, demonstrating how reprocessed glass (from recycled solar panels) could be used in the production of float glass.

Without domestic solar panel manufacturers, such a project might not be worthwhile. But, given the limited number left in Japan, that sort of thing could be needed to even sustain the industry. Japan Solar Panel Recycling mandate could spur further innovation and collaboration. In this way, we are putting Japan on a path to truly sustainable solar energy.

It’s a highly progressive move by Japan, as it will force companies to contribute to the energy sector’s sustainability efforts from the very beginning of a solar panel’s lifecycle by establishing effective ways to dispose of old panels and to recycle the valuable materials they contain.

This approach also represents a step towards a more sustainable future as Japan moves towards addressing one of the key issues of a booming solar energy sector.
