Household cooking oil
A few household hazardous waste programs collect used animal and vegetable oils for biodiesel generation.
Most are available only for a few days following major holidays like Thanksgiving.
Local governments that sponsor cooking oil collection programs often advertise them in utility bills and the local newspaper.
Contact your local government to learn whether this service is offered.
If a collection program isn’t available:
- Landfills aren’t allowed to accept liquid wastes, so animal or vegetable oil should be solidified by mixing it with cat litter or other absorbent to the point that the absorbent is moist, but not dripping.
- The moist absorbent should be double-bagged in trash bags and can then be put in the trash.
- If you have a large quantity of animal or vegetable oil, check your phone directory for rendering plants or other recyclers.
