You say it doesn't save "a lot" of energy, but it still saves energy. And you can do both, you can reuse until the bottle is in too bad condition, and then recycle.

Also, http://www.ferver.eu/en/node/31 disagrees with you that it's not "a lot".

Thanks for that link. I adjust my position on the amount of energy it saves, but I'd like to see an analysis that also includes transportation and cleaning.

Is there a source that's not literally the lobbying group for glass recyclers?
