Description of Invention
This project focuses on developing a sustainable composite material using recycled polypropylene (PP) bumper waste, addressing environmental concerns and repurposing discarded materials. Through a screening process, the recyclability of waste PP bumper was examined, revealing that cycle 01 could be directly recycled into OEM standard bumper, while cycle 02 did not meet these standards. To enhance cycle 02, bio-based nanosilica from rice husks was incorporated into the waste PP matrix, resulting in a bionanocomposite with improved mechanical and physical properties. This innovative solution aligns with Sustainable Development Goals (SDGs) 8, 9, 12, 13, 14, and 15, promoting economic growth, technological innovation, responsible consumption, climate action, and the preservation of both terrestrial and aquatic ecosystems. Ultimately, this project presents an avenue for giving waste PP bumper materials a valuable second life, contributing to a more sustainable future.
