To wonder how to get rid of liquid fat?

We keep being told not to pour oil or liquid fat down the sink because it causes problems for the water companies.

How are we meant to dispose of it? Googling says we should put it into a glass or plastic container and throw it into the main waste but we are supposed to recycle those things aren't we?

I don't have suitable empty glass or plastic containers just lying around and I certainly don't have plastic containers with lids apart from the ones I want to keep like Tupperware.

What do most people do with it?

I collect it and pour it into my Volvo or my lawnmower. sometimes they run a bit funky, in which case I top them up with petrol/diesel etc to dilute the mix.

How can you put newspaper in with food?

I think it's ok. I use recyclable paper bags inside the food caddy and just presumed all paper breaks down. It always gets taken away.

I try reuse whatever i can. If theres meat fat i roast spuds in it next day. My mum would have done fried bread, my grandad bread& dripping. Or you can mix with oats & seeds for birds.

I always use the heavy duty kitchen roll to wipe out pans before washing them. I line a bit of foil with the paper and pour oil into it in the bin.

I mix it with flour until it's a paste then put it in the bin.

You should fry that for breakfast.

there will always be some, even what you eat goes through you when you use the toilet. I try and catch all the oil I cook with, it cools and then I tip it in my bin but there will be some residue in the dishwasher. I have an old house with an outside drain, I regularly clear a mini fat berg from there

I put mine in a jar and chuck it. I don't use that much so I only end up throwing away one glass jar every few months, the current one has been going for ages. The world isn't going to end any sooner because of that. It's far better than putting the fat into the drains

This is what I do. I call it The Fat Jar (though I suppose it’s more properly The Oil Jar)

Maybe use a non-recyclable container to throw it away in? Depending on the area you live in, this could be a pet food pouch, a crisp packet, or a polystyrene curry sauce container from a takeaway.

I spilled some sunflower oil in my sink , one of those "Oh Damn" moments where a Pyrex jug of oil thar was cooling and waiting to filter back in the bottle , fell in the sink . As I grabbed it to stop it smashing , it went down the plughole .
I did the best I could with hot water and washing up liquid to flush it down and emulsify it .

Usually I pour into an empty carton to go in the bin.
We don;t have solid fat .

I am hoping my sewage won;t come back up now and flood my house !

I buy the odd jam or peanut butter in a jar, save the jar, and use it for cooking fats when they're cool.

It doesn't bother me that most plastic and glass containers are supposed to be recycled.

Interesting to read that no one seems to have access to a recycling scheme for fats! Where I live we get buckets with a lid from the council, you fill them up and take them to the tip where the fats are turned into fuel.

We pour it in a old plant pot and freeze it,when frozen put it in the normal waste bin wrapped in tin foil or newspaper

TroysMammy · 09/08/2026 06:50

Does your local recycling centre have an oil section?

Tryanalogue · 09/08/2026 13:48

I’ve been dieting for similar reasons.

ByQuaintAzureWasp · 09/08/2026 21:19

Any old tin, jar, yoghurt pot, bottle, empty milk container ... endless list
