[Biohackers] Does Fermentation Station need a steady stream of beer bottles?

Sat Nov 8 14:42:56 PST 2014

Hi all!

How are you guys doing on collecting beer bottles - should we save all beer
bottles generated at the Omni for you? Or just throw them in recycling?

I'm planning to go buy some trash and recycling bins for Counter Culture
Labs - just wondering whether I should buy a separate one just for beer
bottles, so we can save them up for you.

If you already have a container where you're collecting bottles, just let
us know and we'll tell people to deposit bottles there (just don't expect
them to clean the bottles first, because that ain't never going to
happen...)
