you can get legendary coal from space rocks that you can turn into legendary plastic
upcycling coal (potentially grenades?) could work too

Plastic itself is super cheap so throwing thousands through an inefficient loop might also be a way to go. Otherwise typically asteroids upcycling carbon into coal is the most efficient way to get legendary plastic early on. Later on upcycling LDS is the way to go since infinite LDS productivity means it is 0 loss to do so.

oh, if late game enough
potentially normal plastic -> normal blue chip -> legendary blue chip -> recycle down to legendary plastic

#

or just yoink the red chip out of the legendary blue chip, since that's what you wanted

At +300% productivity in assembler 3 (level 20 infinite research) you can have the assemblers optimised with speed productivity and then the recyclers with 4 quality and a tuned speed beacon to get good throughput. Recycling LDS is 0 loss at that point so you are about throughput rather than reducing the cycle count.

You can do this more easilly with Processing units to make advanced electronics as well.

after a while i finally got it, it was indeed with productivity

#

cryo plants with legendary t3 productivity modules get me to 300% on plastic and 280% on lds (foundry)

#

its been running for a while and while slow, plastic goes up
