I found out today that the company in Framingham MA that recycles Styrofoam (called ReFoamIt) *cannot* take either the pink or blue XPS foam; as it is apparently too dense for their process. Major bummer.
I am looking for a material with a similar density and strength to XPS, that has a minimal carbon footprint. I will probably still use XPS on the first prototype of my CarBEN EV5, but I am not happy about it.
