India's Plastic Waste Fuels Energy Solution?

India grapples with an immense plastic waste problem, generating 26,000 tonnes daily. Plastic-to-fuel technologies, utilizing processes like pyrolysis and gasification, offer a method to convert this waste into usable fuels such as pyrolysis oil and syngas. These technologies are particularly suited for managing the fraction of plastic waste that is difficult or impossible to recycle through conventional means.

While these technologies present an opportunity for energy recovery and economic value from waste, they are not a circular economy solution. Converting plastic to fuel releases its carbon content, unlike material recycling. The high investment costs, the need for a consistent supply of suitable feedstock, and challenges with mixed waste composition are significant hurdles.

India is exploring these technologies through pilot projects, including those by the Institute of Chemical Technology and various Council of Scientific and Industrial Research institutions. Startups are also actively deploying these methods. However, a dedicated policy is absent; instead, plastic-to-fuel is addressed under existing plastic waste management and waste-to-energy frameworks.

This approach prioritizes recycling but allows non-recyclable plastics to be directed toward end-of-life options like waste-to-oil. For effective large-scale deployment, measures like feedstock segregation, quality standards for produce, and stringent emission controls, including safe management of residues, are crucial.
