oil and water: it’s no lie.

Not only is dumping food oils down the drain hard on your plumbing and water treatment plants, it also has a harmful impact on the environment.  Oils form a film on water that interferes with the functioning of water treatment plants by suffocating the bacteria that remove pollution.
 
Simple DOs and DON’Ts:
DO NOT dump cooking oil, poultry fat and grease into the kitchen sink or the toilet bowl.
DO NOT use hot water and soap to wash grease down the drain, because it will cool and harden in your pipes or in the sewer down the line.
 
DO place cooled cooking oil, poultry and meat fats in sealed non-recyclable containers and discard with your regular garbage.
DO use paper towels to wipe residual grease or oil off of dishes, pots and pans prior to washing them.
