🌍 AI-Driven Life Cycle Assessment (LCA) Tool

Advancing Circularity and Sustainability in Metallurgy and Mining

🚀 Developed for Smart India Hackathon (SIH) 2025, this project leverages the MERN Stack to build an intelligent platform that helps industries adopt sustainable and circular practices in the metallurgy and mining sector.

---

📖 Problem Statement

The metallurgy and mining industry is one of the largest contributors to environmental degradation:

• ⚡ High energy consumption
• 🌫️ Significant carbon emissions
• 🌊 Excessive water usage & pollution
• 🗑️ Massive waste generation

Industries lack a transparent, intelligent, and automated tool to measure, analyze, and reduce their life cycle impacts.

---

🎯 Our Solution

✨ The AI-Driven Life Cycle Assessment (LCA) Tool provides a web-based sustainability dashboard that:

• Evaluates environmental footprint across the full cycle (raw material → processing → product → recycling)
• Calculates circularity metrics for materials
• Suggests AI-powered recommendations for eco-friendly improvements
• Generates PDF/Excel sustainability reports for stakeholders

🌱 Helping organizations transition toward a circular economy while achieving net-zero goals
