A small town in Sweden has a lofty goal: to eliminate the use of fossil fuels for heating. And so far its working, as fossil fuel use has been cut down by a staggering 50 percent.
Kristianstad, with a population of around 80,000, has instead started using biogas, a methane gas that is made from biological waste. As an agricultural community, Kristianstad this is a perfect set-up as the city already produces the necessary ingredients for the fuel. The biogas is created from a wide range of waste items, including potato peels, manure, used cooking oil, stale cookies and pig intestines. And it’s not just good for the environment, it’s also has financial benefits. The cost to heat city buildings has been cut by more than half, from $7 million to just $3.2 million.
