Why would you call something "plant based" when it uses a lot of plastic which after short time degrades and exposes it to the environment?

Because it is made from plant based materials? Like some LEGO parts are nowadays made from plant based materials.

Plants -> Ethanol -> Plastic

    Polyurethane is made by (among other steps) mixing paint thinner and phosgene gas. It's a nasty dangerous process.

    The only time plants are involved is when they mix in some fiber pulp at the end.

    Plant based plastics exist, but they are not polyurethane.
