Net Zero Waste

Problem

Most people want to recycle correctly but the rules are local, confusing, and change constantly across regions.

Solution

A mobile-first PWA that identifies the right bin for any item, tracks impact over time, and nudges sustainable habits with real-time guidance.

Approach

React PWA built mobile-first with a service worker that caches the bin-rule dataset offline. Identification runs entirely client-side so the app works on patchy connections in the field. The metrics dashboard aggregates local-only data — nothing leaves the device unless the user opts into sync.
