It looks like this is using lignin as the food stock to make traditional plastics like abs and friends. Super cool, but definitely not addressing bio persistence of those plastics
Not as good as finding an alternative to plastics all together, but certainly cutting down on drilling and dependence on oil countries. Who knows, maybe once BigOil is out of the picture, policy and solutions to microplastics would be more feasible.

The frustrating thing is that eg the bpa substitutes that are used in alternative polymer chemistry to create polycarbonate analogues are chemically similar to bpa and have very high probability of demonstrating similar health issues once relevant science / public health research is supported. Though basically every single plastic monomer has been demonstrated itself to be estrogenic in vitro studies. Even when limited to concentrations that would come from leaching via water or alcohols.
