Or you know, food grade stainless steel straws. No bad chemicals, doesn’t turn to mush (unless exposed to temperatures of 1,400 to 1,530 °C) and fully recyclable. Some people say they are hard to wash but ive never had a problem i just stick em vertical into the silverware holder of my dishwasher and it’s always gotten all the way through the straw clean.
They are cheap to produce as well. Not plastic cheap maybe but businesses could easily replace plastic straws with them without going bankrupt or anything. Easy model is just have em as an optional extra so once people already have 8 they can just use their own lol
