There’s no such thing as a “recycling factory.” When you recycle something, it goes to a central location that performs some rudimentary separating and cleaning, but their job isn’t to make anything. They’re just trying to get your trash to the point where it can be sold to factories. That is, regular factories. Those factories then use the recycled goods the same as any other raw materials.
When your recycling is too messy to be sold to factories, and your local government can’t afford to clean it up to the point that it can be sold, it just goes in the trash.
