Inspiration
Food waste is a major global problem, and many households struggle to keep track of pantry items. WasteZero Chef was inspired by the need to reduce food waste, save money, and make cooking easier. The idea came from seeing friends discard ingredients that could have been used and wanting a smart, AI-powered pantry assistant.
What it does
WasteZero Chef is a smart pantry tracker that helps users:
Keep real-time inventory of all pantry items.
Receive alerts for items running low or nearing expiration.
Generate recipe suggestions based on available ingredients.
View analytics on usage trends to optimize shopping and reduce waste.
Make informed, sustainable choices while cooking — all through an intuitive, user-friendly interface.
How we built it
The application was built using:
Frontend: Next.js, React, Material-UI, Framer Motion for UI interactions.
Backend / Database: Firebase for real-time data storage and user management.
AI / Recipe Generation: OpenRouter / LLAMA API for generating recipes, cultural context, and sustainability insights.
Other Tools: Axios for API calls, Chart.js for inventory analytics, TensorFlow.js for image recognition of pantry items, React Toastify & Notistack for notifications, jsPDF & html2canvas for exporting reports.
Pages / Components: Dashboard, Inventory, Recipe Generator, Inventory Analysis, Profile Modal, and more.
Challenges we ran into
Integrating real-time inventory tracking with image recognition.
Ensuring the AI-generated recipes matched actual available ingredients.
