Vegetable oil recycling is increasingly being carried out to produce a vegetable oil fuel.
In the UK, waste cooking oil (yellow grease) collection is governed by the Environment Agency. All waste cooking oil collections need to be carried out by a company registered as a waste carrier by the Environment Agency. On each collection a waste transfer note needs to be filled out and copies held by both parties for a minimum of 3 years.
Used cooking oil can be refined into different types of biofuels used for power generation and heating. A significant benefit is that biofuels derived from recycled cooking oil typically burn clean, have a low carbon content and do not produce carbon monoxide. This helps communities to reduce their carbon footprints. The recycling of cooking oil also provides a form of revenue for restaurants, which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being disposed of in drains, which can clog sewage lines due to the build-up of fats and has to be collected there as “brown grease” by grease traps.
