Since bioplastics are still a plastic, city legislators in California have every rational justification to ban bioplastics. Suppliers should be doing everything they can to make them "hyper-compostable". Revolutionary solutions also need to come from the collection and reuse side of the equation. If mankind can engineer ways to reuse aerospace rockets, then they can certainly find ways to make bioplastics hyper-compostable. It is definitely a big enough problem that everyone can identify with and feel passionate about to want to solve.
