In the future, sustainable innovation and reduction of environmental impact will be the focus of EPS research. Some of the identified trends in this regard are the development of biodegradable or recyclable alternatives to traditional EPS. Material science developments will be in developing bio-based and nanomaterial-enhanced EPS to advanced strength, insulation, and durability. It will also consider investigating the Use of EPS in Circular Economy Models, with a focus on reuse and recycle. Additionally, there will be an increased interest in understanding long-term EPS effects on ecosystems and human health; this will therefore drive the need for the development of safer, more environment-friendly materials. The next chapter considers such trends, underlining their potential to reshape the EPS industry in upcoming years.
