The disposal route for used cooking oil varies on whether the oil was produced at a domestic or commercial premises.
Commercial Premises
Used cooking oils from commercial sites must not be disposed of with the general waste. They should be kept separate from the general waste stream (in a suitable container) and must be collected by a waste carrier. Details of registered waste carriers can be found on the Waste Directory, which you can access via the following link:
Used cooking oils must never be disposed of to surface water drains, or discharged to the foul sewer without prior approval from the water company.
Under the Animal by-product regulations it is illegal for waste cooking oil to be used as an ingredient in animal feed. There is comprehensive information regarding animal by-products on Defra's website.
Domestic Premises
Householders can dispose of their waste cooking oil in their general household waste.
Waste cooking oils can be soaked into normal household rubbish or placed into rigid plastic containers. Small amounts of waste cooking oil could be soaked into bread as food for birds.
Some civic amenity sites have the facility to accept the waste cooking oil. Householders will have to contact their local authority to see if the facility is available in their area.
