The FOG Problem
Fats, Oil and Grease or FOG is a term commonly used to define the lipid rich material generated during cooking and food processing. The direct release of FOG into the collection system is considered by most municipalities to be illegal. Once in the collection system, FOG can accumulate on pipe walls, potentially forming hardened deposits through a chemical reaction or a physical aggregation process. These deposits lead to a reduction in conveyance capacity and ultimately to sanitary sewer overflows that cost municipalities millions of pounds each year in cleaning, repairing, and maintenance fees.
