PV installation trends and waste projection

Cumulative installation : 34.4 GW by the end of 2015Political target by Gov. : approx. 64 GW by 2030PV module waste projection (lifetime = 25 yrs.)

: 28.5 kt/y in 2030, 62.8 kt/y in 2035, 798 kt/y in 2039

PV module waste projectionDepending upon the assumptions of estimation.

METI/MOE projection assumes an expected panel lifetime of 25 years and initial failure and/or warranty activation in 0.3% of panels installed each year.

Current status of PV recycling in JapanNo statistical data on wasted PV modules

Recently, wasted PV modules are occurred by natural disasters rather than the long-time use.

No specific regulations for wasted PV modulesThe wasted PV modules must be treated under the general regulatory framework for waste management—the Waste Management and Public Cleansing.The act prescribes definitions of wastes, responsibilities of industrial waste generators and handlers, handling of industrial wastes including landfill disposal, and so forth.Some wasted modules are used for the R&D, and ‘reuse’.

Roadmap: Preparation for proper treatment of mass disposalA roadmap for promoting a scheme for collection, recycling, and proper treatment; technology R&D; environmental friendly designs; guidelines for dismantling, transportation, and treatment; and publicity for users, was developed by METI/MOE in 2015.

ObjectiveTo develop low-cost re-use technologies consisted of taking-back, transportation, judgment, repair/restoration

Investigation: Marketing for the EOL (reuse) module (2016)




Concluding remarks


OutlookThe volumes of EOL modules likely will be small in the near term given, and will achieve significant levels in the medium and long term.Although Japan has no specific regulations for EOL PV modules, several political trends and R&D activities are helping build the groundwork for recycling.

Approaches for proper waste management: 3RReduce : reduction of weight/volume, such as higher efficiency, using light materials, etc.Reuse : possible secondary market under the certification/warranty schemeRecycle : recovering materials as much as possible, and hopefully as high-value resources

PV should be ‘CLEAN’, not a cause of a lot of waste.11
