All over the world, fats oils and grease (FOG) clog sewers every day. The United States is no exception. It is believed that around 75% of U.S. sewer systems are working at half capacity because of grease build up and blockages. Billions of dollars are spent each year keeping sewage networks operating.
The problem with FOG is it adheres to the walls of pipes, inside buildings; in plumbing systems and outside; in city sewers, where they can actually form large chunks of hardened fat that mix with wet wipes and other sanitary products, known as Fatbergs. These Fatbergs can be as big as buses and cause blockages which cost municipalities millions of dollars in repair work. FOG also damages pumps in lift stations, and can greatly reduce the efficiency of sewage treatment plants.
