SaniGreen Bioenergy, a joint venture between Canada-based Sanimax and Wisconsin's Green Energy Partners, is developing a $30 million (€22.9 million) biogas plant in South Saint Paul, Minnesota.
The company is expected to break ground on the plant later this year, with completion scheduled for March 2015.
The anaerobic digester will be able to process 150,000 tonnes of solid and liquid waste annually, collected from nearby schools and businesses. Some of the renewable energy generated will be used to fuel a 1.1MW generator which will power the plant.
It will be built close to Sanimax's existing rendering facility and Xcel Energy's centre for electricity and natural gas distribution.
