5 Best Commercial Garbage Disposals Reviewed & Compared

by DisposingAndy

Are you in the market for a food and waste disposal system for your cafe, diner, or restaurant? Take a look at our guide for commercial garbage disposals. These systems are powerful and efficient when it comes to reducing waste in your establishment.

Commercial garbage disposals are an excellent investment for food service establishments. As you know, there is no shortage of food waste when it comes to running a cafe, diner, or similar establishment. It can become a problem when there are not any efficient ways to dispose of waste.

A disposal system allows you to simply rinse off plates and will enable the food scraps to fall into the disposal, which connects to the sewage system. You can then grind up the food into smaller pieces, which allows it to flow away easily. Some models enable you to reduce the mass and catch it in a wastebasket that can then be used for making compost and recycling.

Commercial Garburators According to Size

  • Greater than 1 HP (up to 3 HP) - These models are the most powerful small size disposals on the market. They are generally best for larger businesses that need them to run continuously without much effort. These models would typically be used for restaurants that experience a lot of foodservice waste.
  • 1 HP - All of these models are an upper mid-range size. They are often used in establishments with a slightly larger quantity of food waste, but not as much as a busy restaurant. They are great for a busy cafe or small diner.
  • ¾ HP - These models are generally suited for smaller to moderate-sized restaurants or bakeries. They are great for a low volume diner. They have enough power to dispose of most food waste, but in less quantities than the 1 to 3 HP models.
  • ½ HP - These models are the least powerful of the small commercial garbage disposals. They are geared towards small cafes that do not serve a lot of food products. They are also well suited for low volume diners or restaurants.

The size of disposal that you need will be entirely based on how much food waste you have. For example, a large 3 or more HP unit would not be necessary for a small cafe that serves a limited amount of coffee and food.


Why Use Commercial Waste Disposals

Commercial garbage disposals are a useful investment for food service establishments. There are many positive benefits to setting up one of these units for your business.

In this day and age, we are attempting to become a more environmentally-friendly society. This is one of the main benefits of incorporating the use of a garbage disposal system. Many units on the market will reduce the waste to tiny particles that will not harm society or the environment.

Another great advantage of having a way to dispose of waste efficiently is to protect the plumbing. It is immensely beneficial to foodservice companies. If you do not have a disposal, all of that food waste will be going into the drains of your sinks, which can cause them to become clogged. To unclog them, you would have to hire a commercial plumbing company, which can cost thousands of dollars.

If you throw food waste into the trash, it can rot and create a foul odor. It can also attract many rodents and insects.


Choosing a Commercial Garbage Disposal

Dimensions (Size)

There are many different sizes to choose from when it comes to disposals. It is essential to note the amount of space you have available under the sink before deciding which one to buy.

Generally, the models with higher horsepower will be a bit bigger. Keep in mind when shopping for a new disposal, that you should pick one that will suit your size and strength needs.

Horsepower (HP)

This is one of the most important factors to consider. Overall, the more HP a unit has, the greater the grinding power it will have. A massive 10 HP unit, for example, will provide you with the ultimate grinding power for large foodservice establishments. These models would be ideal for a busy steakhouse with a lot of challenging waste to grind.

A smaller 1 to 3 HP unit will provide less power, which will be more suitable for a smaller business. These units would be ideal for cafes or diners that have food waste that is easier to degrade, such as coffee grounds.

In summary, the more HP a model has, the more difficult the waste it can pulverize.

Grinding Speed Ratings (RPM)

Next to horsepower, the revolutions per minute (RPM) rating is an essential factor in deciding which model to purchase. RPM is the number of times per minute the blades spin.

The higher the RPM rating, the more effectively and quickly the unit will grind up the waste. Ensure that you are getting the appropriate number of RPMs for your needs.

Feed Type (batch or continuous)

There are two different types of feeding methods that you will find in all disposer models. A feed type is a method in which the waste disposal system handles the grinding process. 

The first method is the batch method, which handles waste in batches.  Once the limit has been reached, you switch the unit on, and the food is disposed of. 

The second method is called continuous. During this process, you can turn on the device and continuously put food into the disposer while the blades spin.

Grind Chamber & Shredding Element (Grinder Blades)

This part is what will grind up the food particles that you place into the unit. For this, you are going to be looking at the type of metal that the blades and chamber are made of.

There are a few common types, including stainless steel, galvanized steel, and polymer. Stainless steel is durable and long-lasting. The steel option is durable but can be prone to corrosion. The polymer blended is rust-resistant and relatively long-lasting as well.

Auto-reverse Mode (Anti-jam)

This feature on certain models can be beneficial. Although it is not included in every model, we recommend buying one that includes this feature.

Auto-reverse is used to prevent jams. When there is too much waste in the disposal, the blades will automatically reverse to clear up the jam. Some units may have a switch to turn the blades in reverse.

Sound Reduction

If you have ever heard a garbage disposal, you know they can be loud. Restaurants are already noisy, so if you would like to keep the noise down, you will need to find a model with some form of noise reduction.

There are many different types of noise reduction technologies. These models assist with any unwanted noise levels, especially with the greater horsepower devices.

Electric Cords & Wiring/Electrical Load Requirements

Depending on where you want to place the device, you will need to take into account the power source. Many devices will include a power cord, but some will not.

Another factor that you need to consider is what the electrical load requirements are for each unit. Many of them will be versatile in using 208-220 and 240 volts.

Warranty

We all know how horrible it can be when something breaks and you don’t know how to fix it. Just like many people will purchase a warranty for their car, many disposal units come with a warranty as well.

Many disposals have different types of warranties. We recommend purchasing one with at least some form of a parts-and-labor warranty.

How to Use and Install a High-Powered Disposal

With this guide, you will be able to shop confidently for your next garbage disposal system, but what do you do once you make a purchase?

In this section, we will discuss how to use and install the garbage disposal system under your sink. Most of the devices mentioned above can be installed by yourself. In some occasions, you may need to ask for assistance from a plumber or electrician.

Let’s start with how you should install your new garbage disposal unit. Some of the required tools include a hammer, screwdriver, and pipe cutting tools. Depending on the unit, you may need additional tools.

The first step is to remove the existing assembly under your sink. Next, you should insert the mounting ring into the sink and the bracket underneath. Connect these two components so you can mount the device.

Then, you will attach the tailpipe and the device itself. Depending on if your unit comes with a power cord or not, you may need to connect the wiring. If it comes with a power cord, you will simply plug it in.

The final steps are to attach the plumbing pipes to the device. This is just a brief overview of the installation. For a detailed guide, check out this do it yourself website for assistance.

Once your device is installed, you will be able to start using it. Operating a garbage disposal is very simple. If you have a continuous batch feed model, you turn on the water and the disposal and drop food waste into the sink. It will grind it up into fine pieces with ease.

If you have a batch feed model, then you will insert the food waste into the sink. Once the batch is full, you will turn on the water and the disposal. All of the food waste will be pulverized in seconds.


Other Ways of Disposing Waste

While garbage disposals are great for large volume foodservice businesses, there are other methods of disposing of waste. In the environmentally friendly wave of the future, there are ways you can use both a disposal and other methods.

Composting

One other method of waste disposal is composting. Composting can be implemented within households or businesses. It can be an excellent solution to your food waste management system.

Composting is the process of turning food waste into nutrient-rich soil fertilizer. You can use this fertilizer in your gardening practices or even donate it to farms in the area. If you own a food service establishment, you can create a compost bin. You use a system of tumblers to keep turning the food waste so that it will become fertilizer. You also add grass and leaves to keep the food waste moist and fertile.

Another fantastic thing about composting is you can use this method in combination with some garbage disposals. Thanks to the innovation in today’s society, you can attach devices to your garbage disposal that will turn the food waste into compost that is ready to use in your composting bin.

Recycling

Another popular method for dealing with the waste that comes from most food service restaurants is to recycle it. Much of the plastic waste produced in diners and cafes can be recycled, but what about the food waste?

 If you do not want to implement a composting bin into your establishment, you can also donate the food waste to local plants and farms. They will use it to create animal feed, plant soil, and many other useful substances.


Frequently Asked Questions

How long do commercial food waste disposers last, especially for busy restaurants?
