reverse truck till it fit to the dustbin then press F
after it trashed it all press F again untill it's on origin angle then reverse to the laser to get rid of the empty dustbin. drive the truck a little bit further from the multi emitter then press G to spawn another dustbin. if the truck got full, press H to compressed the rubbish.
