The methane bioplastic recipe appears to be strictly worse than vanilla bioplastic recipe. I suppose the only benefit from the methane bioplastic recipe is it skips a step of needing to make bioflux, but given that the recipe uses both mash and jelly the player might as well make bioflux from that and then make bioplastic with the vanilla method. Given the additional infrastructure for biomethane processing required, I would suggest improving the biomethane plastic recipe to atleast be comparable to the vanilla bioplastic recipe if not better.

Yeah, you're right, I just messed up with ratios. It is intended to be 12 instead of 3 bioplastic in recipe outcome.

This recipe was created with two reasons:
1) Cheaper alternative to vanilla recipe (logistic overhead but less resources required);
2) No need to produce bioflux (can save space);

I'll fix this in the next version.

Check version 1.0.2.

Yep, the new recipe is now a great upgrade from vanilla bioplastic. In my build it effectively halved yumako input which is more than well worth the slight jellynut increased uptake.
