Reducing food waste, one meal at a time

A comprehensive mess optimization and food waste management platform that connects college mess halls with nearby NGOs to minimize food waste, streamline operations, and enable smart donation coordination—backed by real-time feedback, location-based NGO discovery, and data-driven insights.

🎯 Problem Statement

Every day, college mess halls across India waste thousands of kilograms of perfectly good food while millions go hungry nearby. The challenges:

• Overproduction and poor meal planning lead to massive food waste
• No real-time tracking of what's being wasted or why
• Zero connection to local NGOs who could redistribute excess food
• Students' feedback on meal quality gets lost in paperwork
• No location-based system to find and coordinate with NGOs quickly
• No data-driven insights to optimize mess operations and reduce waste

✨ Our Solution

ZeroPlate is a comprehensive mess optimization and NGO coordination platform built with Next.js. Three core innovations:

1. Mess Optimization Through Real-Time Analytics

• Track daily food waste by meal type, dish, and quantity

• One-click scheduling: Complete NGO contact details for instant coordination
• 10 verified NGOs across major Indian cities (Delhi, Mumbai, Bangalore, Chennai, Kolkata, etc.)

3. Voice-Powered Feedback System
