In SimCity Recycling Center is the best building the game could offer as it helps reducing garbage and give resources to industrial building. There is no Recycling Center in Cities Skylines but that does not stop our modders from creating one.
This mod is useful to those who doesn’t want to waste their map space with large landfill.
Now the one I’m using here might be a little bit imbalance for your game. Once plotted, I hadn’t had the need to create any landfill site until my cities had become clogged with traffic.
One plot of this building could handle the whole city within 5k population, unlike Cities Skylines default incineration plant.
