I think there has to be a use for them too. We throw so much away literally every single year that if something could be reused it should be. Bravo for asking. Wish I had an answer not even sure what shape they are. I moved recently to the mountains. Here they dont recycle much it kills me. Bottles that are CRV value only. We had bins for newspapers, cardboard, cans, bottles, you could also recycle assorted paper from the home.. I give magazines to the hospital, books to the cancer ward bookshelf.. I just asked about spools here the other day. Seems like we must toss a ton of those too. Show me what the bottle looks like..
