An efficient waste management ecosystem is crucial to manage the huge waste generated in India’s new energy push

17/03/2022 

In the Budget speech this year, the Finance Minister, Nirmala Sitharaman 

emphasised the role of cleaner technologies such as solar energy and batteries in India’s future economic growth. In addition, she mentioned the importance of transitioning to a circular economy from the existing linear one.

The call for a creation of a circular economy is significant since an efficient waste management ecosystem would be necessary to manage the enormous waste generated by renewable energy projects in the coming decades. 

According to the International Renewable Energy Agency (IRENA) — an intergovernmental organisation that supports countries in their transition to a sustainable energy future —

🍅 the cumulative waste generated by India’s total installed solar capacity could be as high as 325 kilotonnes by 2030.

 A consulting firm, JMK Research and Analytics, estimates

that the market for battery recycling will be around 23 Gigawatt hours (GWh) by 2030. 

The prevalence of a circular economy could also partially insulate these industries from potential supply chain shocks triggered by extraneous developments.

A study by the Council on Energy, Environment and Water (CEEW) has estimated

that India would need over 5,630 GW of solar and 1,792 GW of wind energy to achieve its net-zero target in the year 2070. 

A robust renewables waste management and recycling ecosystem could help people and India reduce environmental harm, provide energy security, and also create new jobs. So, here are six steps to nurture / protect a circular economy in the Indian renewable energy industry.

1 A clear framework

First, policymakers should revise existing electronic waste management rules to bring various clean energy components under their ambit. 

These rules are based on extended producer responsibility that identifies component producers as responsible entities to manage their waste products. 

The Indian renewable energy industry has a complex structure that comprises various manufacturers, assemblers, importers and distributors. 

Hence, the revised regulations should clearly define the responsibilities of various stakeholders involved in the renewable energy value chain

 and provide annual targets for the collection and the recycling of waste.

2 Second, dumping and burning of different components should be banned.

 Currently, in the absence of any regulation, landfilling is the cheapest and most common practice to manage renewable energy waste. 

However, it is not environmentally sustainable. All clean energy technologies thrive on metals and non-metals with different levels of toxicity. 

If the waste equipment is dumped in the open, then these elements could leach into the environment and enter the food chain. 

Studies show that the leaching of heavy metals such as lead and cadmium from solar photovoltaic modules could increase by 90% and 40%, respectively, under acidic conditions.

 Further, burning the polymeric encapsulant layer in solar photovoltaic modules releases toxic gases such as sulphur dioxide and some volatile organic compounds.

3 R&D is essential

Third, the renewable energy industry should invest in the research and development of recycling technologies.

 Recycling is a multistep process that includes 

🍅dismantling,

🍅 disassembly,

🍅 and extraction. 

Dismantling

is largely a manual process that is sometimes automated.

 Disassembly 

can be done mechanically, thermally or chemically. 

Besides these traditional methods, investments in research and development could help discover new ways of recycling that result in higher efficiency and a less environmentally damaging footprint. 

Industries should also explore technology transfers with global recycling firms for establishing domestic waste recycling facilities.

 For instance, efficient metal recovery from waste 

provides a resilient supply of raw material for the renewable energy manufacturing industry.

4 Focus on finance, quality

Fourth, there has to be a creation of innovative financing routes for waste management. 

Access to finance is a major roadblock for players in the recycling ecosystem. 

charge lower interest rates

The central government should nudge public and private sector banks to charge lower interest rates on loans disbursed for setting up renewable energy waste recycling facilities.

 Assurance of a minimum waste quantum 

to run these facilities ।

and issuing performance-based green certificates

to recyclers that could be traded to raise money for waste management would also help ease the financial burden. 

A market for recycled materials

could also be created through mandatory procurement by the renewable energy and other relevant manufacturing industries.

5 there needs to be an improvement in product design and quality.

 Renewable energy component manufacturers should find substitutes for toxic metals such as cadmium and lead used in their products 

प्रोडक्ट के डिजाइन को सिंपलीफाई करना and simplify product designs to reduce recycling steps.

 Such improvements in process efficiencies could go a long way in curbing waste creation at the source and its subsequent impact on the environment.

6 the Union and State governments should set stringent quality control standards for components used in their tenders. 

This will prevent premature end-of-life of components, and consequent waste creation.

 Substandard components generate considerable waste due to early life damage that is often irreplaceable, and the components often have to be discarded. 

Such quality enforcement could also position India’s renewable energy industry as a global supplier of quality products.

Largely in the informal sector

where there are multiple actors involved, but it would be an integral part of our journey toward a sustainable future.

 Further, workers in the informal sector could access various socio-economic benefits and look forward to an improved quality of life.

 We ought to remember that the majority of India’s recycling sector is informal and workers have to work in unsafe environments without standardised wages. 

Therefore, developing an efficient renewable energy waste management and circular ecosystem is imperative rather than a choice. We can ignore this, but only at our own peril.
