Are you wondering where food trucks dump their grease? If YES, here are 5 places food trucks dump their grease in 2023. Indeed, cooking can be a greasy business. Whether you run a food truck with astonishing French fries or an upscale restaurant well renowned for grilling up enticing steaks, you will produce a substantial amount of waste grease as you offer your services.

The very first place grease goes during cooking is up in the air. As food is cooked, a certain amount of the grease released from the food or the oil it is cooking in becomes vaporized. Note that in a well designed food truck or even commercial kitchen, the greasy air will automatically get sucked up into the exhaust hood.

Some of the greases will compile on the hood itself and on the grease filter as the air passes through, but not all of it. Also, any grease that manages to escape the filter will end up inside the kitchen exhaust ducts. According to experts, this presents a huge issue since these grease deposits are quite flammable.

Meanwhile, grease that doesn’t get hot enough to vaporize can end up getting washed down the drain when your food truck crew does the dishes. Also, according to experts, this presents a valid problem, both for the truck drain and everyone involved, because the grease can clog pipes as well as damage water treatment equipment.

Whether you are operating a food truck or trailer, it is imperative you consider how to dump the grease you produce and also all the “gray waters” from your business activities. How you remove grease and more generally gray water is vital even from a legal point of view or you might face heavy fines or have your vending license revoked if you fail to meet this requirement.

Coupled with the legal aspect, disposing of these by-products correctly is the right thing to do. It helps to makes sure that your waste won’t make anyone sick or backup sewer systems of your local municipality.
