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.

I can’t stress enough how much heavy lifting the phrase “among other steps” is doing here.
