Do recycling centers work like this:
The trucks come in with the recyclable goods. Initially, those goods are just generic recyclable.
Then the generic recyclables are "converted" into plastic, metal etc depending on the lines you
installed. If you have 4 plastic lines ALL the generic recyclables are converted into plastic.
OR does it randomly convert a percentage of recyclables into plastic? (or whatever lines you have.)
just like it works in real life.
