I built too many plastic factories, how can I delete one to make room for something else?

Do not fret, the game does not "delete" factories, but simply stores them away in case you want to place them down later. By storing away your excess plastic factories, you can make room for other different factories. Follow these steps:

1) Click on the plastic factory you want replaced

2) A small toolbar will appear under the factory... click the "Details" icon

3) Click "Recycle"

4) A warning will pop up (ignore this, it just means if you store away your factory, you lose the power value that factory gives which is small) - ignore it and press "Ok"

5) You will need to wait a couple minutes for the building to be dismantled and stored away. After about 5 minutes, the tile will be empty and you can place down a different factory

P.S. The level of the plastic factory you "recycled" will be kept and stored away in case you want to put it out again in the future.

Good Luck!
