Our project aims at addressing the plastic waste problem with a novel recycling method. We will specifically focus on the ubiquitous mixed polyethylene(PE)-polypropylene(PP) waste. Since both polymers can not be separated but are also not miscible on the molecular scale, they form low-quality blends upon recycling. By developing special compatibilizers that form crystals at the PE-PP interface, we can make these mixed plastics more compatible, thereby improving their mechanical properties. Importantly, our method is thermally reversible, allowing to recycle these plastics multiple times in a closed-loop system, thereby contributing to a more sustainable future.
