🌱 Inspiration

In a world overwhelmed by fast consumerism, it’s hard to make responsible shopping choices. Most people don’t know if the products they buy align with sustainable values — and there are very few platforms that encourage the resale of eco-friendly goods. That’s why we built Green Cart — where smart shopping meets sustainability.

⚙️ What It Does

Green Cart empowers users to:

♻️ Evaluate the sustainability of products by analyzing materials, manufacturing, and environmental impact.
🌿 Discover greener alternatives while browsing online.
🛒 Buy & sell eco-conscious products in a dedicated marketplace — supporting a circular economy.

🛠️ How we built it

React for a responsive and clean front end.
NestJS for our backend API.
Web scraping tools to extract product data from platforms like Amazon and eBay.
Google Gemini models to analyze product descriptions and determine sustainability levels.
Tailwind CSS for styling and responsive design.
Python to train and fine-tune our AI model for sustainability scoring.

🚧 Challenges we ran into

Parsing and standardizing product data from different marketplaces was more complex than expected.
Integrating the backend with live scraping and frontend display while keeping performance smooth.
Handling inconsistent product metadata and images during scraping.

🏆 Accomplishments that we're proud of

✅ Successfully built a website and extension that analyzes and scores sustainability.
🛍️ Created a user-friendly marketplace that supports both buying and selling.
💡 Integrated AI-driven product evaluation into a real-time shopping assistant.
🌍 Enabled a mission-driven product that has potential real-world impact.

Building a smooth frontend-backend flow with React and NestJS.
Importance of UX when encouraging sustainable behavior — users want it to be easy and informative.
