Comparison Table - Commercial Garbage Disposals

Commercial Garburators According to Size

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?

Most commercial foodservice disposers should last at least 12 years. Many of the models that are offered on the market today come with warranties that include parts and labor. If something breaks before the warranty is up, then you can easily have it repaired.

Are kitchen waste disposers environmentally friendly?

Yes. Food disposals break down food waste into small-enough particles that they do not harm the environment or the water supply. You can also use the chopped up waste for composting and recycling.

Can these garbage disposals handle tougher foods than household models?

Yes. Commercial garbage disposals are designed to handle commercial volumes of food waste. They are generally more powerful and have a long-lasting design.

Do I need a professional plumber to install a garbage disposal unit for my coffee shop or diner?

Depending on the unit you decide to purchase; you may need the assistance of a professional. You may be able to install some units on your own, but many require assistance. We recommend hiring someone if you are unsure.

Where is the best place to buy new commercial waste disposal units?

There are many outlets online where you can purchase commercial disposal systems. We recommend Amazon for the best price.

Garbage Disposal Comparison Table

How Garbage Disposals Work

A garbage disposal unit is basically a grinder that fits under your kitchen sink, between the sink drain and the drain pipe. Its job is to grind food waste into tiny, biodegradable particles that can be washed safely down your drain and out into the sewage system.

To do so, the unit contains a grinding plate attached to a motor. When the homeowner activates the unit, electricity flows to the motor, turning the grinding plate and cutting any food waste inside into teeny-tiny pieces. Water from the sink faucet washes these pieces away when the tap is turned on, while a splash guard prevents any water or food from splashing upward.

This is a great time-saving device and is a must-have for anyone who wants to save time on washing up. It’s especially useful for large families that generate a lot of food waste.

The Value of Having Waste Disposals

Here are just a few of the key benefits of having waste disposals installed in your home:

More convenient

Garbage disposals will streamline your kitchen clean-up and save you hours every month. With a garbage disposal system, you don't have to bother clearing the leftovers off your plates into the trash before you wash them - you can do everything from the sink.

Improved Health & Hygiene

Did you know that your kitchen is one of the germiest places in your home? It’s true - your kitchen sponge actually has more germs than your toilet! Leaving food waste lying around your kitchen in the trash gives these bacteria a place to thrive, which can lead to nasty odors and potential health risks. Using a garbage disposal unit eliminates this problem by getting rid of the food waste instantly. It’s much more hygienic.

Environmental Benefits

Waste disposal units grind up your food scraps into particles that turn into fertilizers in the sewer system. This is a more environmentally friendly solution compared to putting it in the trash as it reduces the amount of food waste that goes to rot in local landfills, releasing greenhouse gas emissions in the process.

Choosing the Best Garbage Disposal Unit (Buying Guide)

To help you to choose the best garbage disposal unit for your needs, we’ve prepared this list of factors to consider:

Waste Volume

The first thing to consider is how much waste your household will generate. The more food waste, the bigger the garbage disposal unit you’ll need. Bigger units typically have stronger motors and, therefore, can handle more frequent use. If you’re living in a home of 4 or more, you’ll probably want to opt for a family-size unit.

The other thing to consider when it comes to sizing is your available space. You’ll need to make sure that the dimensions of the unit you choose will fit within your under sink cabinet.

Motor Power

The motor power is probably the best indication of a garbage disposal unit’s grinding power. It’s usually measured and listed on the product page in horsepower (HP).  Most units will range from 1/3 HP to 1 HP or more.

Typically, the larger the horsepower, the better the unit will be at grinding tough food items like bones and fibrous substances, and the more waste it can handle.

For small to medium-sized households of two to four people, 3/4 HP should be enough. For large homes of 6 or more people, aim for 1 HP or more.

Grinding Capability (RPM)

The RPM is another useful measurement to help give you an idea of a garbage disposal units power. It tells you how quickly the motor spins.  The higher the RPM, the less likely it is that tough food waste like potato peels will cause the system to bind up. On the opposite side of the coin, a high RPM also usually means the motor will emit more noise, so bear this in mind.

Material (durability)

Garbage disposal units tend to vary when it comes to durability and build quality. Cheaper units will have aluminum grinding chambers, whereas more expensive units will have a grinding chamber made from stainless steel, as this is more durable and less likely to corrode over time.

Noise Level

Waste disposal units can be noisy. If noise is something that you're concerned about, look for units that have insulated grinding chambers and smaller motors as these will usually be quieter. Noise levels are typically shown in decibels (dB). Quiet garbage disposal units will typically be around 50dB, whereas loud units can be as high as 100 dB or more.

Feed Type

Garbage disposal units are typically subcategorized based on their feed type. There are two different types to choose from: batch feed and continuous feed. We’ll talk more about the differences between these two types later.

For now, the main thing to know is that batch feed garbage disposals are safer but less convenient to use, whereas continuous feed garbage disposals are less safe but more convenient. Factor this into your decision

Installation

You should also factor in installation costs and time before buying any unit. Disposals that include an electric cord and a quick-mount neck are usually easier to install if you plan on doing it yourself.

Warranty

A final factor to consider is the warranty period. Garbage disposal unit warranties can range from 1 year to 12 years, depending on the model. Some will only cover parts, whereas others will include labor costs too. Generally, the longer the warranty, the more durable the unit is likely to be.

Batch Feed vs. Continuous Feed

Deciding whether to get a batch feed or a continuous feed garbage disposal is probably the most important decision to make. Here are the main differences between each of them in a nutshell:

Continuous Feed Garbage Disposals

These units are usually activated by a wall switch allow you to feed food into the grinding chamber while they're running. They're recommended for large households or anyone that prioritizes convenience. They're NOT recommended for homes with children.

Batch Feed Garbage Disposals

Batch feed garbage disposals can’t be turned on until a rubber stopper is inserted over the opening to the grinding chamber. This enables safer operation as there is no chance of anything slipping into the chamber while the unit is running. The downside is that food can’t be fed into it while it’s running either, it has to be filled in batches beforehand.

They’re recommended for smaller households and those with children.

How to Use a Garbage Disposal Safely

Garbage disposal units can be dangerous if operated incorrectly, so it’s important to make sure you know how to use a garbage disposal safely.

You should always follow the manufacturer's instructions, but here are some general guidelines on how to operate a continuous-feed unit safely:

Note: NEVER stick your fingers or non-food objects into the grinding chamber while it’s running. If a non-food object falls in, turn the unit off immediately and fish it out using tongues - NOT your hand.

Installation Guide on Disposals

Installation instructions vary depending on your manufacturer and disposal model, and you should always follow those instructions before the ones in this post.

You also may be better off paying for professional installation service as, if you're not qualified, you may risk messing up the installation and voiding your warranty.

However, if you're determined to install it yourself and want some general guidelines, here are the necessary steps:

Note: It's your responsibility to make sure you know the correct installation process. Don't consider these instructions to be accurate for every installation or foolproof.

Here's a video that goes into more detail and provides a more visual walkthrough:

Food Allowed & Disallowed in Disposers

Like in any other appliance, there are do's and don'ts to follow. There are also things that shouldn't be put in a garbage disposal unit. Here is a list as a general guideline.

Septic Safe Waste Disposals

Some houses in more rural areas aren’t hooked up to a sewage line and instead, rely on septic systems. If this is you, you’ll need a specific kind of garbage disposal that breaks down the grease, soap, and food waste to help stop it from overloading your septic tank.

Some experts advise against using garbage disposals entirely if your household uses a septic system. However, you should be fine as long as you choose a unit that’s suitable for use with septic systems.

Garbage Disposal Issues and Fixes

Here are some common garbage disposal issues that you might run into and how to fix them:

Noise

If your garbage disposal unit isn’t making any noise at all, it probably isn’t running. Check to see if it’s still plugged into the power outlet as the plug may have become dislodged and if not, contact your manufacturer or an electrician to take a look.

If you notice that your garbage disposal is emitting a louder noise than usual, it’s usually caused by a jam, which is causing the motor to work harder. See below for how to remove a jam.

Jamming

If you’ve put something in the unit that the grinding plate can’t grind down, the unit can become jammed. You’ll know it’s jammed if it hums but doesn’t grind. When this happens, insert an alan wrench into the opening on the bottom of the motor housing and manually clear the obstruction.

Alternatively, if there’s no opening on your model, you can insert a long wooden spoon handle into the drain opening to try to clear it that way.

Clogging

Clogs can be caused by a buildup of debris or fibrous material in your pipes or grinding chamber. Follow the same process as above to remove any content jamming the unit first. If that fails to fix the problem, the clog may be in your drains. If so, use a plunger to unclog the drains.

Leaks

There are several potential causes of a leaking garbage disposal unit, and the correct way to fix it will depend on where the leak is. Here’s a video that will help you to troubleshoot it yourself:

Smells

A nasty odor coming from your garbage disposal usually means there are some leftover food particles or debris rotting inside.

To get rid of it, clean the unit. You can do so by following the manufacturer's guidelines, which may mean using specially-designed cleaning tablets or home solutions such as baking soda and vinegar. You can also put some small slices of lemon peel into the grinding unit and turn it on to cover up the smell.

People Also Ask (FAQs)
