They explore why fats, oil and grease are a problem
Each year almost one million kilograms of fats, oils and grease (FOG) flow down the drains of
homes throughout the capital region.
FOG can cause blockages in our wastewater conveyance system, potentially overflowing into homes, businesses, and the environment. Additional energy and treatment capacity is then required to break down FOG entering the system, increasing costs to operate the sewer system which in turn increases costs to taxpayers.
FOG that makes it through to the ocean can deplete oxygen, damaging fish and other organisms that inhabit the environment.
Identifying sources of FOG can be tricky and include the following:
• Oil and grease from cooking meats
• Cooking oil, butter, shortening, lard, and margarine
• Gravy and oil-based sauces
• Fatty food scraps
• Cooking juices (such as in roasting pans) and floating fats
• All dairy products, including milk, cream, yogurt, ice cream, sour cream,
and cream cheese
Many oils (such as coconut oil) will solidify when they come into contact with lower temperature water in the wastewater conveyance system, therefore creating clogs. If the oils do not solidify, they may still create clogs as they often bind to other forms of fats and grease.
A few simple steps will prevent fats, oils and grease from causing clogs and blockages:
- Wipe small amounts of grease with a paper towel or used napkin and place in compost. In a
growing region, even small amounts add up quickly! Over time, those small amounts can turn
into a bigger problem.
- Cool larger amounts of grease in a container until solid and empty into your kitchen scraps or
- Large amounts of liquid oil (up to 10 litres) can be recycled at the Hartland Depot.
One of the goals of residential source control is to reduce waste at its source in the most effective
and convenient way.
Use a container that is readily available, heat resistant and sturdy. Used
paper coffee cups can be a good option as they can be composted in your kitchen scraps.
Experiment to find the best solution for you.
The key is to wait until the container is full before disposing. If your municipality operates a kitchen scraps program, consider using a compostable container to store FOG. Both the container and content can be placed in your kitchen scraps bin.
