GreenPoint is a comprehensive waste management platform designed to empower BMC (Brihan Mumbai Corporation) collectors with a real-time, dynamic mobile dashboard for tracking and managing household waste collection across Mumbai's residential societies.
This prototype transforms static UI into a fully functional, production-ready system with real-time data synchronization, automatic updates, and seamless workflow management.
Mumbai generates 14,000+ metric tons of waste daily. The current waste collection system lacks:
- ❌ Real-time tracking of collection activities
- ❌ Visibility into collector productivity
- ❌ Accurate data on waste composition
- ❌ Automated reward/penalty systems
- ❌ Society-level waste management insights
- ❌ Data-driven decision making
- Inefficient collection routes
- Difficulty tracking incentives
- Lack of awareness initiatives
- No real-time performance monitoring
- Inconsistent data quality
A comprehensive web and mobile-based waste management system that combines:
- 📱 Mobile App (React Native/Expo) - BMC collector dashboard
- 🖥️ Web Dashboard (React/Vite) - Analytics and management
- 🔧 Backend API (Express.js) - Real-time data processing
- 💾 Database (MongoDB) - Scalable data storage
- 🎮 Smart Features - Gamification, penalties, rewards
✨ Before: Static UI, manual data entry, delayed updates ✨ After: Real-time updates, automatic synchronization, seamless workflow
- Select Collection Point (5+ assigned societies)
- Choose Waste Type (4 categories: Wet, Dry, Mixed, Bulk)
- Enter Weight (in kg with validation)
- Add Notes (optional descriptions)
- Real-time GPS Location tracking
Today's Performance:
├─ Total Weight Collected (kg)
├─ Points Covered (count)
├─ Pending Points (count)
├─ Collections Logged (count)
├─ Average Weight per Collection
└─ Completion Percentage
- Ranked by completion percentage
- Shows completed vs. pending counts
- Contact information displayed
- Last collection timestamp
- Status badges (completed ✅ / pending ⏳)
- Grouped by Date (Today, Yesterday, Last 7 days, etc.)
- Waste Type Icons (color-coded: green/purple/orange/red)
- Weight & Point Name for each entry
- Timestamp & Verification Status
- Filterable by Type
- All Assigned Points List
- Real-time Status Display (completed/pending)
- Contact Information for each point
- Address & Location
- Completion Progress (X/Y points complete)
When a collection is logged:
- ✅ Dashboard updates instantly (statistics recalculate)
- ✅ History updates instantly (new entry appears)
- ✅ Route updates instantly (status changes)
- ✅ No manual refresh needed
- ✅ Automatic success feedback
