Deep in the recesses of GPRA Complex, New Moti Bagh—an upscale, gated colony for civil servants—lies a sewage treatment and waste management plant. This is Delhi’s first zero-waste area, run by Green Planet Waste Management (GPWM).

Smack dab between GPWM’s wastewater treatment and composting centres is a shed where non-recyclable plastic herded from GPRA Complex is turned to oil. This is done through a process called pyrolysis. It’s where the dankest plastic goes to die: milk packets, water bottle labels, torn, oil-stained styrofoam, and dust-laden carry bags. 

About 10% of the daily 50-odd kilos of plastic fed to this pyrolysis plant are disposable trays, food pouches, and cutlery, the kind Rajesh Mittal has seen more of in recent years thanks to food delivery.
