What's the most viable alternative we have to petroleum based plastics? How feasible would it be to abandon petroleum based plastics by 2070?

    Plant based types.

    eg. PLA (Polylactic acid) as commonly used with 3D FDM printers. The commonest production system for that is based on plant starch.

    For info, Casin is one of the earliest plastics, discovered in the late 1800s - and made from milk protein!

    There is no viable alternative to petroleum plastics. The problem is that there are over 4000 different plastics and only a few are recyclable. The cheap ones aren't. they need regulation.
