We bought some eco "bamboo" plates for our toddler because he keeps breaking ceramic plates. But they just mix some bamboo fibres into the plastic. It does feel a bit nicer to touch than normal plastic, but I'm not sure how it is more eco-friendly. It's still plastic that's going to end up in a dump.
(That being said, I don't worry too much about the material of something that gets years of use)
Having just looked at boxes in my kitchen I counted 5 different logos that look the same at first glance, except they're not. 3 arrows with a number in the middle, one circular arrow, 3 arrows with no number, and they're the ones I remember.
It's a hard one because cardboard containers and wooden utensils are objectively better. But clearly also serve the interests of reducing political will for legislation against plastics.
