Ford researchers are hoping to develop 100% petroleum-free automotive plastics to make it to make cars totally compostable - as long as they don't compost while being driven of course. In fact, decomposition is one of the 3 main challenges that Ford is trying to overcome since bioplastic (e.g. polylactic acid) is designed to decompose quickly.
Maybe bioplastic developers can design a time-activated material where vehicles have expiration date and that's when decomposition process starts??
Other challenges that Ford researchers are looking for solutions include less moisture absorption (since natural fiber-reinforced plastics are more likely to absorb moisture causing durability concerns), and odor problems.
