In Iowa, Sioux City’s city council has approved $1.3 million in engineering fees to move forward a product that would clean and upgrade methane produced at its wastewater treatment plant, potentially injecting it into the national gas grid or using it in local fleet vehicles. The $9 million project would use biogas that is currently being burned off, a project that city authorities believe could be paid back in just two years. It could be online as soon as 2018.
