Found this Xmas site, which throws up some amusing suggestions.
Not all eco friendly but I did find these Grolsch glass goblets, made from recycled beer bottles.

I am sure you could fashion one yourself if you hang around in a highstreet after most Friday nights in the UK. Probably a bit too dangerous to do that, so these glasses make an unusual gift for the beer lover, as well as giving a good recycling message.
My personal favourite is the Grolsch tumblers, priced at £9.95 for 2.
