Recycling bottle caps
Good program... but why can't we or why don't we plastic bottle caps?
Often they are made from Plastic #5 which is made from Polypropylene. This material has to be treated differently during melting but that does not mean they can not be recycled.
NPR did a small piece on this with Sierra magazine's Josie Garthwaite that explains this topic a bit more in depth.
