As we near its 100th anniversary, expanded polystyrene (EPS) has become widely used in various industries and applications, especially in construction. Since 1970, EPS has been used in building construction due to its thermal insulation properties, lightweight closed-cell structure, durable strength, and long-term integrity. However, while these qualities make it highly useful and easy to recycle, they have also sparked debate due to recurring discussions about its degradation processes and environmental impact from various perspectives.
While the debate rages on, many improvements and alternative approaches have emerged around this material, highlighting that achieving sustainable construction involves using the right material for the right job from the outset. Thus, over time, innovations have brought new options for the recycling and use of EPS beyond traditional building applications such as infill blocks or partition panels. This demonstrates that rather than stigmatizing it as a problematic or “simple” material, it is essential to consider its qualities through design, technology, and developing methods for responsible and sustainable management.
