What is the proper way to dispose of oil and grease?

• A. Allow oil to cool, drain, filter if needed, and dispose through approved waste streams; never pour down drains.
• B. Pour hot oil down the sink to drain quickly.
• C. Reuse oil without filtration.
• D. Dump oil in the trash.

Answer: (A)

Disposing of used cooking oil the right way prevents clogs, protects the plumbing and the wastewater system, and keeps operations compliant with local waste rules. Letting the oil cool makes it safe to handle, then draining it into a designated container and filtering if needed removes solids so the oil can be directed to an approved waste stream or recycling program. This keeps fats and grease out of pipes and sewers, where they can solidify, form blockages, and cause costly backups.

Pouring hot oil down the sink is dangerous for people and pipes, and it invites clogs and damage. Reusing oil without filtration can compromise quality and health standards. Dumping oil in the trash can leak or create odor and pest issues and may not meet local disposal guidelines. Following the approved waste streams ensures proper handling and environmental responsibility.
