• Gleba and Space both have infinite resources. Make use of it.
• Bring agricultural towers to Nauvis and start planting trees big style. It will eat up pollution like crazy.
• Underground belts don’t work through empty space and lava. Don’t know why I’m surprised.
• Replace every electric mining drill across the solar system with the big drills. It only depletes 50% of the field it works on, comes with its own productivity bonus, has more mod slots and can put stacks on belts later in the game.

Edit for bonus tip:

• As soon as you unlock foundries, switch to them. No reason to melt iron and copper the old way. The new process uses 50 ore and one caltice and gives 500 liquid iron or copper. So it’s fine to export calcite across the system. You can even cast stuff like pipes, steel etc directly. Even low density structures and concrete without all the intermediate steps. (I forgot to mention it has an in built 50% productivity bonus, which is bonkers)
