"What on earth are FOGs?"

searching online about grease legislation

With ever-increasing legislative pressure from the government and large fines being handed out by water companies, it’s vital that businesses within the commercial catering sector have effective forms of grease management measures in place to protect themselves.

Whilst looking for potential solutions to the issue, you’re likely to have seen the term ‘FOGs’ thrown about left right and centre, but you may have been wondering to yourself: “What on earth are FOGs?”

‘FOG’ is an acronym:




These are all essentially forms of grease which will always make it into the wastewater pipe of any commercial catering establishment as by-products of making and cooking food, especially on a large scale.

Whilst any kitchen should already be making sure to pour excess FOGs into a separate container for safe disposal, rather than down the sink, you will never be able to stop all of it from entering the drain due to the processes of keeping dishes, pans and other kitchen utensils & equipment clean. It’s easy to forget how these FOGs will solidify when you’re disposing of them in their melted form, but sewers are much colder than the kitchen, resulting in a consistency much closer to solid lard - or when it mixes with other products which don't belong down the drain like wet wipes - concrete.

This is why Grease Management is such a key area of concern.

Hundreds of businesses have received crippling fines from the water board, due to the lack of measures in place to protect the waterways from excess FOGs – understandable when you learn that it costs the water industry upwards of £15million every year.

These are easily-avoidable issues which could potentially put you out of business, yet you could be forgiven for being relatively unaware of them – remember the London ‘Fatberg’ of September 2017? That was by no means the first occurrence and until suitable grease management measures are implemented by everybody, it won’t be the last.
