Trash truck efficiency is diminished in cities with heavy traffic.Both landfills and incinerators have an operating radius, so in larger cities you can't just place them in one corner.Incinerators create both pollution and noise. Landfills create pollution, but no noise.Additional trash can't be added during the emptying process.While emptying a landfill, a large number of trash trucks will flock to it, thus creating a potential traffic problem.You can't move a landfill until it's been completely emptied.The trucks aren't utilized by other landfills, so you're better off saving the expense of keeping it open. If you can’t empty a landfill right away, you should turn it off.While set to “Empty”, trash trucks will haul trash from the landfill to the incinerators or another available landfill.Once a landfill is full, it can’t receive more trash until additional space has been created through emptying.Landfills provide a maximum of 15 trucks vs the incinerators 27.Go incinerator-only and crematorium-only while making sure to zone residential slowly.
