The reason carbonated beverages have their name is the bubbles of carbon dioxide that are emitted. One of the byproducts of the beer brewing process is carbon dioxide gas. Now an environmentally- conscious brewery in Fort Collins, Colorado, New Belgium Brewery is hooking up with nearby Solix Biofuels to make use of the waste CO2. The 5,000 metric tonnes of CO2 that New Belgium produces annually will be piped over to the Solix facility and pumped into their bioreactor to grow algae. The algae will then be processed into biodiesel fuel. The beauty of the normally scummy algae is that can yield up to 10,000 gallons of biodiesel per acre compared to 50 to 100 gallons per acre for soybeans.
