‘Zerra’ blends Zero Waste and Terra (Earth)
In many parts of India, especially in rural belts like Maharashtra, Punjab, and Tamil Nadu, farm waste like
sugarcane husk, paddy straw, cotton stalks, banana stems, and coconut shells is often either burnt or left
to rot. India alone produces over 500 million tonnes of agricultural residue each year. A large part of this
is either wasted or openly burnt, contributing to nearly 20 percent of the country’s annual particulate
pollution.
I’m Palak Samani, a student who grew up in a small, agri-intensive town called Sangli, where
the sight of blackened fields was part of everyday life. I’ve seen how much effort goes into growing a
harvest, and how quickly the leftovers are ignored or thrown away.
Zerra is a simple platform that helps farmers list leftover agricultural residue and connect directly with
businesses that can use it for products like biofuel, compost, fibreboard, and sustainable packaging. Our
goal is to make it easier for farmers to earn more, protect the environment, and build a cleaner supply
chain that works without middlemen or complications.
Right now, we’re working in India. But our goal is to grow into a platform that supports rural communities
everywhere, helping them turn leftover farm waste into something useful, earn a little more, and reduce the
damage to their land and air along the way.
For the farmers. For the environment. For the buyers.

As part of our commitment to sustainable agriculture, we’ve developed a prototype mulch made from natural
clay and turmeric — designed to replace plastic mulch films that dominate Indian farmlands. This zero-waste
solution improves moisture retention, reduces water usage, protects microbial life, and minimizes fertilizer
runoff.
The mulch is shaped like a flat pyramid, creating a microclimate that reduces evaporation and shields the
soil. It’s embedded with basic moisture and temperature sensors, allowing data collection on real-time
field conditions.
