The "Trash to Treasure" platform offers a novel solution to the pressing global issue of improper waste disposal, aiming to mitigate environmental pollution and promote sustainable waste management practices. With over 62 million tonnes of waste generated annually and a significant portion left untreated, traditional waste management methods have proven insufficient. This project addresses the challenge by creating an online platform that connects waste sellers, waste buyers, and creative sellers, facilitating the reuse, recycling, and recovery of waste materials. Through the platform, waste sellers can upload details of their waste inventory, while waste buyers can purchase materials for manufacturing purposes, fostering a circular economy. Additionally, creative sellers can showcase their upcycled products, thereby promoting the reuse of waste materials. Moreover, the platform offers a unique feature to assist the best out of waste sellers in predicting the pricing of their creations, enhancing their economic viability. By promoting the adoption of the 3R principle (Reuse, Recycle, Recover), the "Trash to Treasure" platform aims to contribute to the creation of a zero-waste eco-friendly environment. This research paper explores the design, implementation, and potential impact of the platform in addressing the critical issue of improper waste disposal and advancing sustainable waste management practices.
