Depending upon the facility. Some places do quite a bit of sorting on trash. Especially things like metals. While they don't have a separate bin. They might still filter or export some components to be recycled?
In many places in Europe consumers separate their waste themselves prior to collection, Holland included. Any waste that hasn't been separated and is just in a rubbish sack and presumed to be non-recyclable and buried without being opened or sorted. The metal cans in Holland end up in the rubbish sacks and are buried forever along with non-recyclable plastics, food waste, nappies etc
