I recently submitted an article to PM Engineer Magazine asking the question, "is there FOG in food waste?" which was published in the September 2015 issue.

I came under some criticism for my position in objecting to having food waste disposers routed directly to sanitary under two proposed changes to the 2018 International Plumbing Code.
This article attempts to explain, based upon very basic research I conducted on the subject, why I believe food waste disposers should be routed through a grease interceptor, by means of a solids interceptor (as the IPC currently requires) to intercept the food waste in order to prevent the solids from prematurely filling up the interceptor.
Those in favor of routing FWDs directly to sanitary have attempted on multiple occasions to make their case. This article simply attempts to present an opposing position for readers to consider.
