In India’s quest for energy security and sustainability, the imperative to foster a circular economy for renewable energy technologies emerges as a strategic imperative.
Recognising the criticality of minerals such as silicon, lithium, cobalt, and copper in advancing the clean energy transition, the Ministry of Mines identified 30 minerals as pivotal for India’s energy future, necessitating concerted efforts to ensure a resilient and sustainable supply chain. The adoption of circular economy strategies presents a compelling opportunity to mitigate supply risks and bolster the uninterrupted progression towards clean energy. Strategies encompassing the reuse of products and components, alongside material recovery from waste, stand poised to transform India’s renewable energy landscape. A recent study by the Council on Energy, Environment and Water (CEEW) underscores the magnitude of the challenge, revealing that India’s burgeoning solar capacity has already generated significant waste, projected to escalate in the coming years. With an estimated 100 kilotonnes of waste generated in FY2023 set to surge to 340 kilotonnes by 2030, proactive measures are imperative to manage this burgeoning waste stream effectively.
Central to India’s circular economy vision for renewables is the imperative to enhance recycling capabilities, reducing reliance on critical minerals and insulating against associated supply chain vulnerabilities. While technological innovations such as reduced silver content in solar cells and decreased rare earth element consumption in wind turbines show promise, scalability hinges on stability and performance. To accelerate the adoption of circular strategies, policymakers must enact clear mandates and provide regulatory signals to incentivise waste recycling in the renewables sector. Regulatory targets for waste collection, recycling, and reuse, alongside stringent quality control measures, are pivotal in fostering a conducive ecosystem for circular economy practices. Furthermore, integrating circular strategies into standard operating procedures and enhancing quality standards will drive demand for circular products, thereby incentivising investment in recycling infrastructure and technology. By embracing a circular economy ethos, India can not only bolster its renewable energy resilience but also chart a sustainable path towards a greener and more prosperous future.
