The airy challenge: transforming expanded polystyrene waste into value

June 24th, 2024

Presentation by Ahmad Kandjani (CSIRO)

Expanded polystyrene (EPS) is widely used in packaging, construction, food industries, and more. Its formability and lightweight nature make it an ideal material for various applications. As a polymer composed of over 95% air, EPS is invaluable in situations where lightness and strong mechanical and thermal properties are crucial. However, its lightweight nature poses a significant challenge for recycling, as the cost of transporting EPS waste is often prohibitive. To address this issue, we aim to introduce a portable compacting and pyrolysis unit that can make EPS recycling more feasible. This solution is designed to be easily adopted by small to medium-sized industries that deal with EPS waste on a daily basis. In this presentation, we will provide a brief introduction to the growing problem of EPS waste, discuss methods for addressing this issue, and explore innovative approaches to upcycling EPS waste in detail.
