GreenCycle

HackPrinceton 2024 Submission

GreenCycle is an innovative application designed to make recycling effortless, empowering users to contribute to a greener planet while earning money. With features that combine gamification and cutting-edge AI technology, GreenCycle redefines how people approach recycling.


🌍 What is GreenCycle?

GreenCycle enables users to:

  • Scan items to determine recyclability.
  • Locate nearby recycling centers with ease.
  • Earn rewards for recycling efforts.

Our app addresses common challenges in recycling:

  • Ambiguity: Not all items, such as Styrofoam medication packaging, are recyclable.
  • Lack of Incentive: Recycling can feel inconvenient and unrewarding.

🚀 Motivation

  • Recyclable Waste: 75% of the waste we generate is recyclable, yet much of it ends up in landfills.
  • Economic Impact: If all recyclable waste were processed, the global market potential exceeds $234 billion per year. Even on a smaller scale, Princeton alone could generate $904,000 annually through recycling.

🎮 Features & Value Add

  • Gamification: Inspired by successful apps, GreenCycle makes recycling engaging and rewarding.
  • Monetary Incentives: Users earn money based on their recycling contributions.

🛠️ How We Built It

Frontend:

  • Developed with HTML, CSS, and JavaScript.

Backend:

  • Built with Flask.
  • Integrated a LangChain agent powered by a Large Language Model (LLM) for:
    • Answer retrieval.
    • Item recyclability validation.
    • Integrated LangChain agent with web using Tavily API.

Demo:

  • Created using Figma for showcasing app functionality.
