Cooking oil and fat should not be poured down sinks as it can cause blockages
HWRC accepts cooking oil or place small amounts with your kerbside food collection
Tip: Google – ‘cooking oil recycling Wales’ to find out who operates a service near you.
Alternatively for small amounts (works the best with solid fat such bacon/lamb/beef/pork but not liquid oil), why not mix it with bird seed in an empty yoghurt pot, add a small stick with string attached and put it in the fridge to solidify. You can then hang it from a tree in your garden and feed the birds in the winter.
