Every morning, before most of Sambalpur city stirs, Sunita Pradhan is already on her rounds. 

She moves through the city’s lanes in a waste collection vehicle, stopping at homes to collect segregated garbage. Wet waste goes into one section. Dry waste into another. Along the route, residents greet her by name. 

A few years ago, Sunita worked as a daily wage labourer. Today, she is a Swachha Sathi — a sanitation worker, community educator, and, in a very real sense, one of the people keeping a mid-sized Odishan city from drowning in its own garbage.

And making it richer in the process.

Sambalpur Municipal Corporation (SMC) is generating around Rs 20 lakh every single month from waste — compost sold to farmers, recyclables sold to vendors, and materials recovered at its network of ‘Wealth Centres’. 

The city reportedly processes more than 170 metric tonnes of waste every day across nine decentralised Wealth Centres. Most of the revenue comes from dry recyclable waste, while compost sales contribute a much smaller share. 

It is not a pilot or a startup. It is a functioning, replicable urban system built on deceptively simple logic: stop seeing waste as a problem to be buried, and start treating it as a resource to be sorted.

How Sambalpur’s wealth centres work

At the heart of SMC's system are its Wealth Centres — decentralised facilities where collected waste is segregated, processed, and converted into sellable material. Wet organic waste is composted into ‘Mo-khata’, a high-quality organic fertiliser that has found a steady market among local farmers and nurseries. 

According to officials, recyclable materials generate nearly Rs 18 lakh to Rs 19 lakh every month, while Mo Khata compost contributes another Rs 45,000 to Rs 50,000 through retail and bulk sales.
