The best way to dispose of fat, oil and grease (FOG) from cooking is to solidify thin oil or grease with things such as coffee grounds, kitty litter or even laundry detergent, then dispose of the solid waste. Alternatively, you can place the fat, oil and grease into a sealable container, such as an old coffee can or a plastic jar with a lid, then throw away the jar after it has cooled. The reason to go through all of this trouble is because fat, oil and grease clog up sewers and pipes, and they can sometimes even turn into soap while working their way through the sewer system.
