Food Type Guide

FOG values

Select the food service type that best matches the establishment. The calculator maps the selected food to the correct FOG value, then adjusts for disposable or non-disposable utensils.

FOG values used by this calculator are based on the food-service categories and grease generation factors published by Miami-Dade DERM. The calculator applies those published values to produce a preliminary grease load estimate. Final grease interceptor selection remains subject to engineering review and approval by the Authority Having Jurisdiction.

Reference: Miami-Dade County DERM FOG Guidance / Grease Interceptor Sizing Methodology.
