Best Way To Dispose of Cooking Oil

Used cooking oils and fats can cause huge problems if not disposed of correctly. But what is the best way to dispose of cooking oil? It depends whether you are a homeowner trying to get rid of your old oils, or a commercial business with huge amounts of used cooking oils which need to be disposed of.

For the homeowner, the quantities of used cooking oil which you need to dispose of are generally really small, usually after you have cooked your steak or burgers of an evening there will be some residual cooking oil and fat left in the frying pan. It’s tempting to simply pour this down your sink isn’t it? However this is probably the worst thing you can do, It could clog up your drains, leading to costly plumbing repairs and smelly drains in your house. As the majority of household waste water is sent to sewage plants to be treated before being discharged back into the environment, there are also huge environmental issues too. The problem with this is that most sewage treatment works are not able to remove all traces of used cooking oil from the liquid, so they end up becoming a breeding ground for bacteria and can over time (with many different household doing the same thing) clog up the mains sewer pipes. These clogs when left un-treated turn into “fatbergs”.

Fatbergs are sewer blockages caused from the build up of solidified cooking fats mixed with other household waste that have not been disposed of correctly. These fatbergs can cause huge problems as they release unpleasant smells, and in some cases can cause sewage to spill out onto the street during times of heavy rain. Local councils spend £1000’s each year in the combat against fatbergs, the teams of sewerage workers really have one of the dirtiest jobs in Britain.

What Can Homeowners Do?

The best way to dispose of cooking oil as a home owner is fairly simple, you should pour out any fats and cooking oils into a suitable container, a jam jar or an old plastic bottle for example before the cool down and solidify. Once done, a lid should be placed on the container and then it can be disposed of in your kitchen bin.

And For Commercial Businesses?

If you run a restaurant, fast food business, café etc… disposing of used cooking oils is a bit more tricky. Due to the larger quantities involved there are certain legal requirements that you should adhere to in order to dispose of used oils correctly. There are specific rules in how your cooking oils should be stored, especially onsite within food preparation areas. You can’t just dispose of your oils and fats in the bin as you would if you were a home owner. This type of cooking waste is classed as a hazardous waste, most recycling companies don’t handle this type of waste either, you need to seek out a specialist waste carrier who will collect this waste for you and dispose or recycle it. They should also provide you with the relevant paperwork which is required by law, failing to have this paperwork can result in your business being shut down temporarily, or at worst closed for good!
