The aim of this project is to understand where recycled plastic should be used. The project will analyze the environmental impact from using recycled plastics in product applications with different lifetimes. For example, how beneficial is it to recycle packaging material (short lifetime) in furniture products (longer lifetime). The project will also study the impact of different recycling systems on these results. Which type of products should be recycled in closed loops rather than open loops? Or are reuse solutions preferred? A better understanding of these dynamics will help policy makers and companies to make well-informed decisions when designing new circular systems.
