$60 per kilo

That's not bad for a prototype! With lab-growth meat, the initial cost was $2.3 million / kg. It's come down since then because of process and scale improvements, but when it starts off that high, it's going to be a while for it to become affordable.

A quick non-AI figure is $0.60 per kilo to recycle plastic... so we just need improvement by a factor of 100 which is quite realistic.
