According to Nikkei News, Japan's Niimi Solar Company (Niimi Solar Company. Xinmi City, Okayama Prefecture) will put a pyrolysis device that can recycle about 95% of solar panels into practical use. The technology has already been developed, with the first unit due to be delivered in June, and is expected to generate a significant amount of end-of-life solar panels from the 2030s onwards. As an environmentally friendly device that does not emit carbon dioxide, it is expected to meet the needs of industrial waste treatment companies and others.
Niimi Solar Company (Nimi City, Okayama Prefecture), a developer and marketer of solar power generation systems, will determine specifications in terms of verifying processing speed, heat distribution within the equipment, operability, etc. . The goal is to sell one or two devices to various parts of Japan (prefectural jurisdictions) within 10 years, for a total of about 100 devices. This price will be adjusted for component procurement costs and other factors.

01 Influence of practical application of solar panel pyrolysis processing equipment
The volume and size of obsolete solar panels is currently insignificant in the e-waste market, but it is growing fast. The problem of waste (landfill) of solar panels is increasing year by year around the world. According to the forecast of the Japanese Ministry of the Environment, the amount of discarded panels is expected to continue to grow in the future, and is expected to increase sharply from 2,351 tons in 2015 to about 800,000 tons in 2040 (only in Japan). In response to this problem, Japan's Niimi Solar Company (Niimi Solar Company. Niimi City, Okayama Prefecture) will put into practical use a pyrolysis device that can recycle about 95% of solar panels.

02Recent development of the technology
With the initiation and popularization of the feed-in tariff (FIT) system in 2012, solar power generation has developed rapidly. The product life of solar panels is generally 25-30 years, and it is expected that a large number of panels will be disposed of after 30 years of use. According to the Ministry of Environment, the number of discarded panels (with a lifespan of 25 years) across Japan will increase rapidly from 28,700 tons in 2030 to 775,000 tons in 2039.

03 Problems and challenges to be considered in recycling waste solar battery panels
Worldwide, the disposal of used solar panels is increasing. Therefore, countries around the world should formulate relevant recycling incentive policies and measures. European solar panel manufacturers have begun to establish their own scrapping business and allocate funds for the recycling and subsequent processing of discarded solar panels. It can be seen that innovation and public policy are the key to solving the issues related to waste solar panels.
