It is quite true that Aluminum could (and hopefully one day will) be more environmentally friendly that plastic. If more than 1/3 of the aluminum we produce in the US came from recycling and/or the majority of energy used in primary aluminum production came from renewable sources, then aluminum would be a big win. Unfortunately, I don't think we are there yet.
