In this blog post, we’ll explain why you should never do it, what problems it can cause, and how you should dispose of your cooking oil and food scraps properly.

Why is pouring oil down the sink drain is bad?

Oil or grease from cooking oils usually is thick in consistency, and grease clogs can solidify into fatty deposits once cool. These will stick to pipes and drain ways. And the more cooking oil or oils such as bacon grease that is washed down the sink, the more fatty deposits can grow over time and cause a grease-clogged drain .

Not only that, but oil can also combine with other waste items like wet wipes, hair, and food scraps to form a hard blockage known as a “fatberg“. These monstrous masses of fat can clog up sewer systems and cause major damage to the infrastructure and the environment. For example, in 2017, a 250-metre long fatberg described as being “as heavy as 11 double-decker buses” clogged up a Victorian-era sewer in London for weeks . Fatbergs are also a problem in Australia, especially in winter when cold temperatures help fats and oils solidify .
