Inspiration

The sheer fact that the world produces over 3.5 million tons of waste every day was enough to get us thinking—what can we do about it? Improper waste management isn’t just bad for the planet; it’s a missed opportunity to recycle and compost materials that could otherwise be reused. We wanted to make a difference, not just by creating a tool, but by spreading awareness and empowering people to take small, meaningful actions.

What it does

The Smart Waste Sorter is a web application that helps users easily sort their waste by using image recognition technology. By simply uploading or capturing a photo of waste, the app classifies it into one of eight categories: Light Bulbs, Paper, Plastic, Organic, Glass, Clothes, Metal, and E-Waste. After identifying the waste type, the app provides detailed instructions on how to properly recycle or dispose of the material, helping users make informed decisions. Beyond just sorting waste, the app aims to raise awareness about the importance of responsible waste management and sustainability, encouraging users to adopt eco-friendly habits and reduce their environmental impact. It’s a simple yet effective tool that empowers people to contribute to a cleaner, greener world.

How we built it

We created the Smart Waste Sorter to make waste sorting as simple as snapping a photo:

Machine Learning Model: Trained to identify 8 types of waste—Light Bulbs, Paper, Plastic, Organic, Glass, Clothes, Metal, and E-Waste. Frontend: Built with HTML, CSS, and JavaScript for an intuitive, user-friendly experience. Backend: Powered by Python frameworks to process images and integrate the ML model. Tools and Libraries: TensorFlow for training, OpenCV for image preprocessing, and Flask for deployment.

Challenges Faced

Training the model was no easy task. We struggled to achieve high accuracy due to variations in lighting, image quality, and material similarities. It took trial, error, and patience to fine-tune the model through meticulous preprocessing and data augmentation. Integrating it seamlessly with the web app brought its own set of challenges, but teamwork and determination helped us push through.

Accomplishments We're Proud Of

  1. Accurate Waste Classification: Successfully developed a model to classify waste into 8 categories for easy recycling and disposal.
  2. User-Friendly Design: Created an intuitive interface for effortless image upload and waste sorting.
  3. Raising Awareness: Promoted responsible waste management and sustainability through the app.
  4. Seamless Integration: Built a smooth web app combining machine learning and user-friendly features.
  5. Continuous Improvement: Refined the app and model based on user feedback for better performance.

What we learned

This journey taught us more than we expected. We dove deep into waste classification, learned how image recognition can solve real-world problems, and discovered how technology can inspire change. Along the way, we sharpened our skills in machine learning, web development, and creating user-friendly designs. Most importantly, we realized that small steps toward sustainability can lead to a bigger, positive impact.

What's next for Smart Waste Sorter

  1. Expanding Waste Categories Currently, the app recognizes 8 types of waste, but there’s so much more we can do. Future iterations will include more categories like hazardous waste, construction debris, and specific subcategories for plastics.

  2. Community Features We plan to introduce a feature where users can share tips, recycling hacks, or local recycling center information, creating a community dedicated to sustainability.
