WasteToWealth - Connecting Farmers and Companies for Sustainable Waste Management

WasteToWealth is a web application that bridges the gap between farmers who produce agricultural waste and companies that can utilize this waste for various industrial purposes. This platform facilitates sustainable waste management by connecting waste producers with waste consumers.

🌱 Project Overview

This is a college-level Node.js web application built with Express.js that enables:

• Farmers to list their agricultural waste (crop residues, organic waste, etc.)
• Companies to post their waste requirements for raw materials
• Matching System that connects suitable farmer-company pairs based on waste type and location

🛠️ Tech Stack

Backend

• Node.js - JavaScript runtime
• Express.js - Web application framework
• MongoDB - Database for storing user data and listings
• Mongoose - MongoDB object modeling

Frontend

• EJS - Embedded JavaScript templating engine
• CSS - Styling (custom stylesheets)

Authentication & Security

• Passport.js - Authentication middleware
• Bcrypt - Password hashing
• Express-session - Session management

Additional Libraries

• Multer - File upload handling (for waste images)
• Method-override - Enable PUT/DELETE requests
• Connect-flash - Flash messaging
