Kitchen grease, commonly referred to as FOG (fats, oils and grease), is an unavoidable by-product from food preparation and food serving areas. It also is a major problem in municipal/public sanitary systems as grease accumulates until the flow in the drainage system is restricted enough to cause sewer back ups and overflows.
