The National Solar Energy Federation of India (NSEFI) has revealed that by 2030, over 34,600 tonnes of solar waste could be generated in India. Despite India’s ambitious solar power installation targets, a solid solar waste management policy is currently missing. The problem of solar waste looms ahead with the anticipated increase in discarded solar panels, and there are increasing concerns about India’s readiness to handle this projected rise.
Solar Waste in India: A Looming Issue
According to NSEFI, an organization dedicated to addressing issues related to solar energy growth in India, solar wastes are essentially electronic waste emanating from discarded solar panels, which are sold as scrap in the country. It’s predicted that these wastes will quadruple or quintuple over the next decade, hence the urging for comprehensive rules on dealing with solar waste.
The report suggests that by the end of this decade, India will be grappling with significant solar waste problems. Solar panels usually have a lifespan of 20-25 years, hence the waste issue seems distant. However, it’s noteworthy that while photovoltaics generate only around 3% of global electricity, they consume large portions of the world’s elements such as tellurium, silver, and semiconductor-grade quartz, among others. Interestingly, the raw materials recovered from solar panels could be worth USD 450 million by 2030 and might exceed USD 15 billion by 2050.
Management of Solar Waste Globally
Several countries, including the European Union (EU), the UK, USA, Australia, Japan, and South Korea, have started developing strategies to handle solar waste. The EU’s Waste Electrical and Electronic Equipment (WEEE) Directive puts the responsibility of waste disposal on the manufacturers or distributors who initially introduce or install the equipment. Similarly, in the UK, there is a “take-back and recycling scheme” managed by the industry.
In the USA, states like Washington and California have enacted Extended Producer Responsibility (EPR) regulations for solar PV modules. Australia’s federal government has also embraced the issue by announcing a USD 2 million grant to develop an industry-led product stewardship scheme for PV systems. Lastly, Japan and South Korea are keen to enact dedicated legislation to address the PV waste problem.
Recommendations for Solar Waste Management
Several approaches can be employed to manage solar waste effectively. Firstly, strong e-waste or Renewable Energy Waste Laws need to be enacted, where manufacturers and developers take responsibility for the end-of-life of solar panels. Infrastructure investment is crucial to bring down recycling costs, while environmental disposal and recycling provisions should be part of power purchase agreements. Bans on landfills could also discourage disposal of solar panels in such areas due to their toxic substances.
Furthermore, incentivizing the recycling industry through green certificates or new business models could encourage participation. Additionally, research and development can result in design innovation to minimize renewable energy waste. For instance, new panels that use less silicon produce less waste during manufacturing.
Indian Initiatives Related to Waste Management
India has drafted a handful of waste management initiatives such as the Draft EPR Notification: Plastic Packaging Waste, Plastic Waste Management Amendment Rules 2021, E-Waste (Management) Rules 2016, E-waste (Management) Amendment Rules 2018, and Central Pollution Control Board. However, there is still a pressing need to develop comprehensive strategies specially tailored to manage the projected rise in solar waste.
