PSA Group, SOLVAY and SOGEFI have teamed-up to produce the first Plastic Diesel Fuel Filter fully made of recycled polyamide 66, ready for mass-production. This has been achieved by using the brand new plastic compound developed by SOLVAY Engineering Plastics. This material is 100% recycled from airbag wastes, providing a premium material able to stand demanding applications requirements supplied though circular economy, which is quite unusual in automotive industry yet. SOGEFI has tested this material through its existing plastic injection process, and tested the parts on extensive bench validation tests. It confirmed that this material is fully compatible with standard injection process, and that all the tests have been passed successfully. Finally, PSA Group has driven the choice of the tested parts: DV engine 1.6l Euro6b application, homologated the material grade and evaluated the whole validation process. A Life Cycle Analysis has been conducted also, demonstrating the benefits on overall CO2 emissions, impact on non-renewable resources, water up-take, human health and eco-system. It has been therefore demonstrated that circular economy and substantial benefits for the ecology could be introduced up to serious and demanding applications, required by latest generation engines.
