Biomaterials, agromaterials, vs traditional plastics

I’m quite excited about bioplastics in particular and would like to reactivate this thread if there’s no other one about this topic. I know that there have been some developments in furthering the production process and available materials, I’ve seen lots of things like grass, flax+PLA, potato starch, even tea and pine needles. I’m sure a material can be found to cultivate that doesn’t compete too much with agricultural soil for food production.

My concerns are more with how similar bioplastics can be to traditional plastics in terms of mechanical and aesthetic properties and especially production costs. Does anyone have experience producing with bioplastics and willing to share their experiences, or references to good articles?
