What is a garbage disposal unit and how does it work?

A garbage disposal unit is an electronically powered device that is typically attached to the bottom of your kitchen sink. It shreds your leftover food in extremely small pieces so that it can pass easily through the plumbing. They are considered to be a household necessity in most areas and are very popular in Canada.

Taking out the garbage is a lot easier through the use of a garbage disposal unit. It works like this:

  1. You switch on the garbage disposal unit.
  2. Place the leftover food in the sink.
  3. Turn the tap on so that there will be heavy water flowing.
  4. The water will push the leftover food down the drain. Sometimes, you will need to carefully manoeuvre the leftover food towards the drain but make sure not to place your hand near the drain.
  5. The scraps go down the drain and into the grinding chamber inside of the garbage disposal unit. This is where the shredding blades will start to cut up the food.
  6. Remember not to turn off the tap to avoid overheating or prevent small pieces from flying up leaving a mess.

How can they help the environment?

In the US alone, an estimated 150 million tons of waste is buried yearly in landfills and only 40 million tons of it is recycled. Add that to the waste generated by other advanced countries and the figure will be overwhelming. By using garbage disposals, you will:

  • Help keep food scraps out of landfills
  • Help reduce diesel fuel consumption and the emissions that are commonly associated with garbage trucks
  • Convert the waste into useful resources like fertilizer since the waste will ground up and pushed down the drain and into a wastewater treatment center
  • Help reduce greenhouse gas emissions because the waste is broken down faster than in a landfill

Types of Garbage Disposal Systems

Continuous Feed – it works the second you switch it on and stops working the second you turn it off.


  • Great if you have a huge amount of waste to grind up every day
  • Recommended if you are always cleaning up as you cook
  • Much more inexpensive than the other type


  • Prone to accidents
  • Requires more water compared to the other type

Batch Feed – it grinds food in batches. It will start grinding once it reaches a certain weight or if it has been filled.


  • Uses a stopper, which means there is no huge gaping hole in your kitchen sink. Much less chances for unwanted items to accidently fall into it
  • Recommended if you don’t have to discard a lot of waste every day
  • Safer than the continuous type because it needs to be filled before it will work. It also needs the cover to be placed in before it starts grinding.


  • Will take long if you have quite a bit of waste every day
  • You might be tempted just to stuff it in there until you have more waste which will lead to bacterial growth, which can cause illness and insect infestation

The main differences between the two types are basically the price, amount of waste needed to be disposed of and safety concerns. So it’s up to you which type you feel more comfortable with and which one will cater to your needs.


Advantages and Disadvantages of Using A Garbage Disposal


Very convenient – flushing your food waste down the drain sure beats having to pack it and place it in the garbage.

Reduces health risks – reduces bacteria build-up in garbage bins. These bacteria can contaminate the food in your house since the trash in the garbage bin is usually only collected once a week.

Reduces cost – since you don’t need to constantly buy garbage bags and doesn’t really eat up a lot of energy, you will feel the savings over time.


Chance of clogging – foods like eggshells, undercooked pasta, cheese and certain vegetables can cause clogging and might require the help of a plumber to fix.

Accident prone for children – if you’ve got children around they might get curious and insert their hand and accidentally switch on the garbage disposal. So make sure to educate them on what it is and what it might potentially do so that they will avoid it.

Can be quite noisy – some models generate quite a bit of noise.

Tips for Longer Garbage Disposal Life Span

  1. Use cold water to make the food easy to chop up and grind. Hot water can soften the food which might cause clogging.
  2. Regular use is key to avoid corrosion and rust in most models of garbage disposal units.
  3. Once it is done grinding the food waste, run a little extra water just to rinse out the waste.
  4. Don’t feed all the waste into the garbage disposal all at once.
  5. Use citrus peels to kill the bacteria and at the same time, ensure that your kitchen smells good.

What to Avoid Putting Into the Garbage Disposal Unit

  • Grease or oil
  • Potato peels
  • Glass, metal, plastic or paper
  • Rice, pasta and other foods that expand

How Do You Choose the Right Garbage Disposal Unit?

Before you buy a garbage disposal unit, you need to make sure you choose the right one for your needs. When shopping for one, always keep in mind that cheaper doesn’t always mean it’s the better option.

First thing you need to do is to check the local regulations on garbage disposal units. Some areas will prohibit the use of garbage disposal because it will cause too much strain on the sewer lines.

Another thing you need to figure out is if your plumbing can handle the extra movement through the drains. This will be a little hard to figure, so don’t hesitate to call a professional for help. Once you’ve done that, you will need to see what type of unit your kitchen sink can accommodate. Usually, a local plumber will be able to answer those questions. One good tip before you go to the store and buy one is to show the salesman a picture of your sink on your phone.

Another thing to consider is if there is an electrical outlet nearby for your garbage disposal unit. If not, you will need additional work to wire into an existing circuit and make an on/off switch.

Motor power is another important consideration. You can use a smaller motor if you live alone. Otherwise, going for the largest motor on the market is more recommended because will less likely burn out with everyday use.

Choosing a model that have blades made from stainless steel is the best option to avoid corrosion and rust. Keep in mind that stainless steel blades last the longest, and are harder and sharper than other metals. If you see cheaper units, it will most likely use little to no stainless steel and will likely break down and wear out faster than the one using stainless steel blades.

Other considerations you need to factor in are if the unit has corrosion protection inside or if it comes with a splash guard. These options will help keep you kitchen sink looking neat and tidy.


There a lot of great reasons to get a garbage disposal unit. As mentioned above, using one is considered to be one of the best be eco-friendly ways of disposing our food waste. You will find that getting a garbage disposal unit will be a great investment because it will make hosting dinner parties a lot less difficult because of the quick cleanup. This will then allow you to spend time with your friends and family and a lot less time cleaning in the kitchen. Hopefully, this article will be a great help for your search on the best garbage disposal for your kitchen.
