A device that is steadily growing in popularity is the automatic grease trap .

It is a mechanical grease trap consisting of a plastic or stainless-steel waterproof tank with a system of scum-boards and partitions, supplemented with a system that is capable of automatic or semi-automatic cleaning. It means that sludge can be removed without directly opening the trap. Everything can work simply on the basis of the connection of a suction vehicle to a quick-connection coupling, which is installed on the external façade of the building. Therefore, this system is mainly used in places where the opening of the trap may cause hygienic problems, i.e., in restaurants, fast-food shops, kitchen facilities, and meat and meat product processing plants.
