Eli5 why are so few plastics recyclable? Why cant you just melt it down and reuse it like glass?

I was reading that just one wrong type mixed in with a batch can turn an entire vat into useless goo that will take hours if not days to clean out.
but there’s just no money in it. except for some minor amounts used to make fleece and some lumber decking substitutes, it costs far more to carefully separate, to truck it over, to clean it well enough…. than to get some petroleum waste product to make fresh new plastic.
Even glass isn’t profitable, our local refuse won’t take it anymore.
