Danbury's FOG-to-fuel solution

摘要

Fats, oils, and grease (FOG) waste is a serious and growing problem for the wastewater industry and the environment. Every year, grease costs municipalities millions of dollars in clogs, equipment damage, and sewer line repair. Not only is FOG costly to handle and remove, but it is also the primary cause of sewer backups. The largest source of grease comes from restaurants and commercial kitchens. Ideally, grease is thoroughly wiped off all cookware and utensils prior to washing. In practice, however, it is faster and easier to remove the grease with hot water, particularly in a busy kitchen. Unfortunately, this means grease is going down the drain. Once it cools down in the sewer pipes, the grease begins to clump and adhere to pipes. Over time, the grease blocks them altogether - causing backups and leading to serious public health and water quality problems.
