In the garage you have trash bags, use them to collect trash piles. In store you can buy item box and put trash bags in it, then send it by drone, they send you some money for it. Buy more trash bags in store, collect more trash and send it.
Ta-da, you got rid of trash and got some money.

Ye, just to store garbage so it won't take up space on ur base, but sell it will give you more profit. I think that by collecting all the garbage from the generators and base you will get about 1000+ points in total !
Tip: if you want to save money a little - buy 12 trash bag, not 1 roll. 12 trash bags costs 12 points, 1 roll (which have 12 trash bags in it) costs 15 points. You will need a lot of trash bags, so...
