I can't figure out how to make plastic?

Hey there!
I already unlocked all the necessary research and have all the bots to build a plastic factory, but for some reason I can't? I'm playing as UE on the forest plannet and I even unlocked alien tech but the building menu doesn't show me the plastic factory. I already built a crudebot to harvest some oil.
Pls help, i'm confused.
Here are the requirements
