“Once you capture landfill gas, there’s three things you can do with it,” Brown said. “You can flare it into the atmosphere — which is basically burning it — you can run an electric turbine with it and produce electricity or you can capture it and make it into liquid fuels.”
The first two options are not ideal, Brown said. Flaring methane gas wastes a valuable resource, but does less harm to the environment than releasing methane, he said. Turbines are not cost-effective because of the huge capital investment involved in generating electricity.
