Recycling used cooking oil (also known as FOG’s – “Fats, Oils and Grease”) is always the best option. Many landfills do not accept the substance, since in its liquid form it can contaminate water tables.
Pouring it down the drain is a leading cause of sewer backups for homes and businesses. Soap and hot water do not break down the grease; they merely carry it further down the drain where the water cools and oils begin to congeal in the pipes, eventually forming a wall of grease.
Residents are asked to mix fats, oils and grease with absorbent waste such as paper towels, kitty litter, coffee grounds, or shredded newspaper before discarding in the trash.
Restaurants are now required to store fats, oils and grease in containers that are picked up by permitted recycling and rendering facilities. These facilities can convert the FOG into viable resources such as biodiesel. Biodiesel is a renewable fuel made from waste cooking oils and renewable energy crops.
