Inventor turns brewery waste into natural gas

Read the full story from the Associated Press.

Before he started “saving the earth, one beer at a time,” all inventor Eric Fitch knew about home brewing was that it could make quite a mess.

Once, he accidentally backed up the plumbing in his apartment building by dumping into his garbage disposal the spent grain left over from his India Pale Ale home brew. The oatmeal-looking gunk choked the pipes in his Cambridge, Mass., building, flooding the basement.

These days, he’s doing something more constructive, fulfilling the dream of beer lovers everywhere by recycling the stuff: The MIT-trained mechanical engineer has invented a patented device that turns brewery waste into natural gas that’s used to fuel the brewing process.
