There’s a difference between a market and a significant market.

40% thrown away does not necessarily imply all others are better.

Normally imperfect produce goes to processing plants (juice, cans, pies etc.) but I’m not sure if there’s any significant market for banana chunks/puree.

I’m not sure that lossy compression on vectors is strictly impossible.

You can do things like store less colour information and simplify splines so that curves are less complex.

If it’s not got design drawings, specifications, and QC, it’s improvised.

I can make any ad-hoc modification to a machine and be paid for it, and that’s improvised.
