Several versions ago, there was a mod (maybe called "homeworld") that had a sink of you sending various resources through a portal back "home". It started simple with N iron plates, but then they wanted 10N oil barrels, and eventually red circuits. It also added some farming resources (which were affected by local pollution, so you had to plan where to put them). It was fun to have little goals, but I don't know that it's been updated recently.
