An autoclave requires distilled water and an enormous amount of energy to operate. You could save the water but you'd potentially need to distill it again after. They use an enormous amount of energy and water overall.

The feed for the cells still has to come from somewhere too, and the growth of the cells is aerobic and generates CO2. That said, artificial meat is supposed to hit market parity price by 2026 and probably below parity after. [1] We will probably see a rapid transition to cultured meat within a decade. There are a very large number of these companies competing right now. [2]

"supposed to". I am hopeful but I think we are very early here and it is going to be very difficult to actually meet these targets. We shall see.

Sure. But then you have to spend way more energy on the "filtering" part. It typically makes a lot more sense in terms of energy usage to just take tap water and run it through a polishing step (deionization and/or reverse osmosis), than to take the comparatively "dirty" water coming out of your process (dirty but not toxic) and try to clean that up.
