eco friendly machine.

will they want to add eco friendly machine, to reduce pollution in my base ?

There was a "Survivial Mod" (misspelled on factoriomods.com, actually Survival Mode) which had potato plants that sucked so much emission out of the air that a few of them could make a basic mining patch going full tilt totally undetectable. It also has the catastrophic problem of implementing respirator equipment that didn't let you upgrade your armor until it had an equipment grid.
