Recycled high impact polypropylene in the automotive industry - mechanical and environmental properties

Popis výsledku v původním jazyce

The use of recycled plastics remains an open issue. The common opinion being that recycled plastics have better environmental profile but worse mechanical properties. But is it really so? Various studies show no significant deterioration of the plastics qualities up to five or six reprocessing cycles and the environmental impacts have to be considered for the product whole lifecycle. If we take into account the increasing transports and impacts of recycling technologies, the advantages of recycled High Impact Polypropylene (HIPP) become less clear. In this study we take a closer look on recycling of HIPP, the most common polymer in car body parts, such as bumpers. To verify its advantages and drawbacks we combined two methods: test of mechanical and rheological properties depending on the number of reprocessing and Lifecycle Assessment (LCA) to verify environmental friendliness of the HIPP recycling. On one hand, our findings reveal that unlike Polypropylene (PP), HIPP mechanical properties start to deteriorate from the first reprocessing. On the other hand, like in the case of PP, we have not observed a significant deterioration before the 6th reprocessing. The LCA shows that road transports have a very small impact on simple HIPP product whole lifecycle. The main difference between virgin and recycled HIPP is based on the production process itself and electricity consumption for recycling. Our model proved decreasing impacts with any addition of recycled content, except for the ionizing irradiation potential category, which is typical for the French power grid mix.
