to Garbage Disposals: Making Your Life Easier

Have you ever wondered what happens to the food scraps you throw down the sink? Well, if you have a garbage disposal, they get ground up and washed away through the sewage system or into your septic tank.

Garbage disposals are a handy appliance that helps you dispose of food waste in an environmentally-friendly way. In this article, we will explore the different types of garbage disposals, their benefits, potential issues, and how to choose the right one for your needs.

Definition and Function of Garbage Disposals

Garbage disposals, also known as food waste disposers, are electrically-powered devices installed under your kitchen sink. Their primary function is to shred food waste into small particles, which can then be easily washed away down the drain.

These particles are usually small enough to pass through the sewage system or get broken down in septic tanks. By using a garbage disposal, you can effectively reduce the amount of food waste that ends up in landfills.

According to the Environmental Protection Agency (EPA), food waste is the single largest component of municipal solid waste. By grinding up food waste, you are helping to divert it from overflowing landfills and reducing greenhouse gas emissions.

Benefits of Garbage Disposals

Garbage disposals offer several benefits that make them a convenient and eco-friendly addition to any kitchen. Here are some of the key advantages:


Eco-friendly: As mentioned earlier, garbage disposals help reduce the amount of food waste that goes into landfills. Instead of decomposing and releasing harmful gases, the waste is sent to sewage treatment plants for proper processing.

This not only helps protect the environment but also minimizes the production of methane, a potent greenhouse gas. 2.

Easy to clean: With a garbage disposal, you can say goodbye to smelly food waste sitting in your trash can. Instead of dealing with regular trips to the outside bin, you can simply rinse your food waste down the drain.

This not only saves you time but also keeps your kitchen smelling fresh and clean. 3.

Reduce odors: Food waste left in trash cans can quickly become a breeding ground for bacteria and create unpleasant odors. By disposing of food waste immediately through a garbage disposal, you eliminate the stinky smells that can linger in your kitchen.

4. Save space: By using a garbage disposal, you can free up valuable space in your kitchen.

With a smaller amount of food waste going into the trash can, you won’t need to empty it as frequently. This can be especially beneficial if you have limited kitchen space or live in a smaller apartment.

Types and Usage of Garbage Disposals

Now that we’ve explored the benefits of garbage disposals, let’s dive into the different types and their usage. Continuous Feed vs.

Batch Feed Models

1. Continuous Feed Models: This type of garbage disposal is the most common and widely used.

As the name suggests, continuous feed models allow you to continuously add food waste while the unit is running. They feature a switch or an electric wall switch that you can use to turn the disposal on and off as needed.

Continuous feed models are perfect for quick and convenient disposal of food waste during meal preparation and cleanup. 2.

Batch Feed Models: Batch feed models, on the other hand, require a bit more interaction. They are designed with a lid or a stopper that needs to be placed over the disposal opening before it can be turned on.

Once the lid is in place, you can activate the disposal, and it will continue to run until the lid is removed. Batch feed models provide an added safety feature, as the disposal will not run unless the lid is securely in place.

This makes them a great option for households with young children.

Potential Issues with Garbage Disposals

While garbage disposals offer many benefits, it’s important to be aware of potential issues that may arise. Here are a few common problems associated with garbage disposals:


Plumbing issues: Over time, food waste can accumulate inside the disposal and cause clogs in your pipes. To prevent this, make sure to use cold water while running the disposal, as hot water can cause fatty substances to solidify and create blockages.

2. Clogs: Certain types of food waste, such as potato peels, corn husks, and fibrous vegetables, can be challenging for garbage disposals to handle.

Avoid putting these items down the disposal, as they can get stuck and cause clogs. 3.

Leaks: Over time, the seals around your garbage disposal may become worn or damaged, leading to leaks. Regularly inspect the area under your sink for any signs of water damage or dripping.

4. Sink back-ups: If you overload the disposal or put in large quantities of food waste at once, it can overwhelm the drain pipe and cause a sink back-up.

To prevent this, feed the disposal a little at a time and allow it to grind the waste thoroughly before adding more.


Garbage disposals are a convenient and eco-friendly way to dispose of food waste. They help reduce the amount of waste that ends up in landfills and make your kitchen clean-up easier.

With careful usage and maintenance, you can enjoy the benefits of a garbage disposal while minimizing potential issues. Consider the type of garbage disposal that best suits your needs, whether it’s a continuous feed or batch feed model.

Incorporating a garbage disposal into your home can make a noticeable difference in your daily routine and environmental impact. Cost and Installation of Garbage Disposals: A Worthwhile Investment for Your Kitchen
