Did you know that 8500 tonnes of methane can generate over 100 gigawatt hours (GWh) of renewable energy each year? What natural bi-product can produce this much methane each year? Pig poo. That’s right; New Zealand’s pork industry has the potential to produce renewable energy by converting the methane emitted from pig manure using biogas digesters.
An eight-month energy trial is underway so that researchers can identify the most effective projects and share that knowledge with farmers. The conversion to renewable energy not only is capable of producing heat and electricity, but also reduces greenhouse gas emissions. Since methane is over 22 times more harmful to the environment than carbon dioxide, this is a great place to start.
