Another Cooler Design That Uses Natural Insulating Materials Rather Than Plastic
It's also made of steel, alumnum, wood and rubber that is all bolted together. The end user only has to remove 46 screws in order to separate the wool from the rest of the junk metal pile. Why not just ditch the wool inside and make some sort of aluminum baffle system that acts as insulation without the dual-material problem... You also can't just throw wool into a "recycling" bin. It requires a separate means of collection. Heck, wool (textiles) recycling isn't even available everywhere so some people have no choice but to throw away the wool liner assuming they get that far.....
