Here at Things Are Good we tend to like beer and we’re always happy to see the brewing process become more environmentally friendly. A smart inventor in the USA has found a way to convert a naturally occurring element of the brewing process and converts it into natural gas!
The brewery is Magic Hat and their motto is “Saving the earth, one beer at a time” – I can’t wait to try their beer.
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.
The anaerobic methane digester, installed last year at Magic Hat Brewing Co. in Vermont, extracts energy from the spent hops, barley and yeast left over from the brewing process — and it processes the plant’s wastewater. That saves the brewer on waste disposal and natural gas purchasing
The 42-foot tall structure, which cost about $4 million to build, sits in the back parking lot of Magic Hat’s brewery, where it came online last summer.
Fitch, 37, is CEO of PurposeEnergy, Inc., of Waltham, Mass., a renewable energy startup company whose lone product is the biphase orbicular bioreactor, which is 50 feet in diameter, holds 490,000 gallons of slurry and produces 200 cubic feet of biogas per minute.
Brewers big and small have wrestled with waste issues since the dawn of beer-making. In recent years, they’ve turned to recycling — both as a cost-saver and for environmental reasons.
