I was always a bit surprised to see these. At work, we used to have your classic Nespresso plasticy-cardboard coffee cups. They could be reused during the day, but you'd basically throw them away after a few uses.
Now we get some "eco" "compostable" ones. To my untrained eye, aside from the different color, they look and feel exactly the same. They even have a drawing on them that I interpret as "we kill turtles". Not sure how these can be considered "green". I'm also curious how healthy it is to drink a hot beverage out of them.
The eco cups are PLA. They are derived from a completely different source from the petrochemical plastics. While that doesn't on it's own make them completely safe, they likely have massively different properties from other plastics.
