Beer-o-fuel?

I've read about a lot of substances researchers are attempting to turn into biofuel -- everything from restaurant trap grease to spent coffee grounds to algae.

But never this: Bloomberg is reporting today that the world's second-largest brewer is joining the British government in a $38 million effort to turn brewing waste into biofuels.

The company is SABMiller Plc, which makes Grolsch and Miller Lite.

It's about time I could drink a beer without feeling guilty about all those emissions. Not that efforts haven't been made. When I worked in West Chester, the brewer there gave spent grains to a local cow farmer.  According to Bloomberg, Anheuser-Busch uses giant balloons to capture natural gases emitted in the brewing process that are then re-used at several of its plants.

Cheers to all of them.
