This research provides insights about successful business strategies water resource recovery facilities (WRRFs) in the U.S. have used to create value and manage the risks of adopting co-digestion of food waste – including fats, oils, and grease; food manufacturing residuals; and food scraps – with wastewater solids to enhance recovery of biogas, soil amendments and nutrient products. The report presents a framework that can help WRRFs develop a long-term business strategy and implementation plan that can be used to advance their mission and long-term goals. Published in 2019.
