WHY PLASTIC
STAYS UNSORTED

01

PEOPLE CAN'T TELL PET FROM HDPE

India has 7 plastic resin codes. Most people recognize water bottles but can't distinguish LDPE film from PP containers. Without identification, everything goes to general waste.

02

A SINGLE LOCATION'S PLASTIC ISN'T WORTH A TRIP

A scrap dealer burns ₹45 in fuel driving to collect 200g of mixed plastic worth ₹4. The economics don't work for single-location pickups. Dealers simply refuse.

03

AGGREGATED PLASTIC IS A PROFITABLE COMMODITY

Sorted PET fetches ₹28–35/kg. HDPE reaches ₹38/kg. When multiple households, restaurants, and shops in a cluster each cross the 2.0 KG Digital Bin threshold, a single route yields ₹400+ profit for vendors.

THE 30-MINUTE BARRIER

"IF SORTING TAKES 30 MINUTES, I'LL JUST THROW IT ALL AWAY"

Vineeth runs a general store near Warangal. He keeps PET water bottles aside because he recognizes them. Everything else — LDPE bags, PP cups, HDPE containers — goes straight into mixed waste because he can't tell them apart.

Nirvaha eliminates this barrier. Anyone — from shopkeepers and restaurant staff to individual households — points their phone camera at any plastic item and get the exact resin code, estimated weight, and sorting advice in 2.2 seconds. No training needed. Items accumulate in a virtual Digital Bin. At 2.0 KG, the system triggers a profitable neighborhood pickup route for scrap vendors.

HOW NIRVAHA WORKS

FROM WASTE TO ROUTE IN 4 STEPS

SCAN

Users photograph plastic waste with the Nirvaha Flutter app. Gemini 1.5 Flash identifies the exact resin code in 2.2 seconds.

CLASSIFY

AI returns resin type (PET 1 through OTHER 7), estimated weight, recyclability index, and automated sorting advice.

AGGREGATE

Each classified item enters a virtual Digital Bin. Weight accumulates across days — no daily collection trips needed.

ROUTE

At 2.0 KG, the bin triggers a pickup. Vendors claim entire neighborhood clusters via the live dashboard with OpenStreetMap routing.
