Plumbings and drainage systems tend to get clogged, especially in commercial settings. It’s nearly unavoidable that you’ll run into this problem. But you can get things under control by installing commercial waste disposal.

In the US, garbage disposals aren’t uncommon. In fact, most households have them, regardless of the income. But what distinguishes commercial garbage disposals from residential models is that the former can process large volumes of food waste efficiently.

A commercial equipment can also operate for hours. They usually have a power range of 1 HP and higher. And they don’t have complex features, either. All they do is chew on food waste all day – from meats to bananas to bones. Then, allowing the shredded food to smoothly pass through a plumbing system.

Commercial garbage disposals are efficient pieces of equipment that tirelessly handle massive food waste. Having the best commercial garbage disposal installed in your kitchen can reduce their environmental implications.

Whether you own or run a restaurant, café, or coffee shop, you’ll depend significantly on well-functioning commercial waste disposal.

In this article, I will go over all of the essential information that you may find helpful in picking the best garbage disposal unit. But first, let’s take a look at the most common perks of using commercial waste disposal.

Advantages of Having a Commercial Garbage Disposal

Looking at the benefits of garbage disposals is critical in finding the best option for you. And if you’re curious why you should invest in a waste disposal machine, below are a few reasons:

Handles massive amounts of food waste

Hotels, restaurants, cafeterias – these food establishments produce a lot of food waste. Disposing of such waste materials in a landfill can result in a multitude of contaminants. This is because the waste is too much to handle even though it will eventually break down.

A heavy-duty commercial garbage disposal is great at discarding food waste. It also makes cleanup a breeze. 

Prevents unpleasant smell in your Kitchen

Have you ever walked into a kitchen that smelled terrible? Where do you think that odor comes from?

Shooting your food scraps in the kitchen garbage can cause it to decay. And if you leave it there for a few days, the waste will start to release a foul odor. A commercial garbage disposal can do the trick in eliminating the unpleasant smell.


There are certain places that do not employ commercial waste disposal. However, it isn’t the most convenient approach to disposing of waste in a trash bin. It’s just laborious and poses health and sanitation issues. Also, using the trash can means you will be filling the garbage bags faster.

Plastic bags are a potential hazard. And by using the garbage disposal, you limit the amount of waste you need to dump in the trash can.


Loading up trash bags means you’ll need to toss away many bags in a single day. This means that you’ll have to go out each time to discard garbage. With a garbage disposal, the amount of runs to the larger garbage bin or landfill is minimized. It takes care of most of the waste, making your job easier.

Saves the Environment

Most consumers use plastic bags to discard food waste. Those plastic bags will inevitably end up in landfills. Because landfills emit methane and other polluting gasses, it can result in air pollution. A waste disposer reduces the possibility of such repercussions.

Saves Plumbing System

Commercial garbage disposals are an excellent way to protect the plumbing system. So instead of allowing massive food pieces to slide down your drain, this machine smashes them into tiny pieces. Which will encourage a smooth flow of waste down the plumbing. And this will reduce the likelihood of clogs.

No Pests

Most folks are unaware that a large amount of waste in or outside the kitchen might draw pests. The safety of your customers should be your top priority. Using the garbage disposal keeps rodents at bay.

Those crawlies don’t have enough room to reproduce and pose a health risk in the kitchen. When you use the waste disposal, you instantly get rid of the food waste and keep things tidy.


Having commercial garbage disposal saves you money in the long run. By minimizing the risk of clogging, you will be less likely to need to call a plumber or replace the plumbing system. The upfront cost is worthwhile for reliable garbage disposal.

The Best Commercial Garbage Disposals

Picking the right waste disposer for your business is critical, as the wrong unit can cost you more in both investment and upkeep. That being said, I went on the hunt for you and gleaned information from thousands of verified users. Here are a few of the best commercial garbage disposals I found:

InSinkErator Evolution Excel Garbage Disposal – Best Overall

InSinkErator Evolution Excel Garbage Disposal

Quiet but powerful, the InSinkErator Evolution Excel Garbage Disposal has a 1 HP Dura-Drive induction motor that is both durable and solid. Breaking through even the toughest of waste, it’s one of the best commercial garbage disposals on the market for a variety of reasons.

What I appreciate the most about this unit is the low noise level. Equipped with an insulated SoundSeal Technology, this feature ensures that the noise level is not compromised throughout the operation.

Aside from its sound-reducing mechanism, it’s also equipped with a quiet collar sink baffle. These two features cut noise by up to 60 percent.

This commercial garbage disposal is built to last. It’s made of alloy stainless steel and has a LeakGuard Liner for maximum durability. This unit also uses a 3-Stage Multigrind Technology to tackle the hardest of leftover foods.

Another feature I appreciate is that it employs a jam-sensor circuit. This feature raises the motor’s torque by up to 500 percent. Which provides smooth functioning while chewing on the toughest jams. It also has a 40-ounce grind chamber that can accommodate a large quantity of food waste at once.

• Quiet yet powerful
• Durable construction
• Works smoothly with jam-assist feature
• 3-stage grinding
• Easy to install
• Lengthy warranty
• Heavy
• Does not come with a power cord

Waste King 3000-3 Commercial Food Waste Disposer – Best Power

Waste King 3000-3 Commercial Food Waste Disposer

The Waste King 3000-3 Commercial Food Waste Disposer is one of the heaviest-duty commercial disposers on the market today – thanks to its 3 HP motor. Because of the power it provides, it can break through and grind up a wide range of fruits and vegetables. As well as tough meat fibers and bones.

It features two hardened stainless steel swivel impellers that increase waste removal efficiency. And then, they retract if jammed. This will also minimize the likelihood of overheating the motor and save you money in the long run by avoiding the need to hire a plumber.

The stainless steel undercutter blade also offers extra cutting power if the blades happen to fail. I find this a great perk as these blades are efficient at breaking through the toughest food waste. This unit is driven by a strong motor and rotates at 1740 revolutions per minute.

While it’s a powerful commercial garbage disposal, it includes a hush cushion to help minimize noise. This cushion separates the metal from one another, preventing the metal from crushing against each other.

It also contains a splash guard, which allows the disposer to function without spilling garbage all over the place. For optimum grinding, it’s equipped with a cast iron grinding chamber. Keep in mind that it only needs a little energy to grind.

I think the drawback of this waste disposer is the short warranty. Which is shorter than most commercial garbage disposals on the market.

• Powerful HP
• Durable construction
• Comes with a noise-reducing mechanism
• Comes with durable backup blades
• Less overheating
• Short warranty

InSinkErator 79024-ISE Garbage Disposal – Easiest to Install

InSinkErator 79024-ISE Garbage Disposal

One of the easy ways to tell whether or not commercial garbage disposal will give you hassles is the ease of installation it offers. The InSinkErator 79024-ISE Garbage Disposal makes replacing your old unit a breeze. It features a patented Quick Lock sink mount, so just twist off your old waste disposal and twist on this unit.

This garbage disposal offers increased grinding capabilities and 1 HP. Which eases your worries about the food it shreds or what’s going on in your pipelines. It can break down tough food waste like peach pits with a single-grind stage with jam-preventing torque.

What I love about this InSinkErator is its compact size. It is smaller than many other commercial waste disposers, which makes it an ideal choice if you don’t have much space under the sink. This unit is also built to last, having a rust-resistant, stainless steel grind chamber and components.

• Easy to install
• Powerful enough to break through tough food waste
• Prevents jamming
• Compact size
• Durable design
• Lengthy warranty
• Not suitable for heavy-duty use
• Single-stage grind only

InSinkErator PRO1100XL Pro Series – Good Option

InSinkErator PRO1100XL Pro Series

The InSinkErator PRO1100XL Pro Series made the cut on my list because of its durability and reliability at an unbeatable price. And as you know, power is everything when it comes to commercial use. This garbage disposal is equipped with a 1.1 HP motor, making it ideal for hectic restaurants.

It’s not as powerful as other commercial disposals. But it has the muscle to break through meats, fruits, and other items. The MultiGrind technology with three-stage grinding also deserves praise as it works well in pulverizing food waste in just a few seconds.

And if for whatever reason, this unit locks up, the auto-reverse function and jam sensor will come in handy. In addition, the Quiet Collar has an antimicrobial layer wrapped around it to suppress sound and prevent any unwelcome microbes from growing beneath.

Keep in mind though that since the blades are so strong, they take a long time to slow down. So you must avoid shoving anything down the machine after shutting it off.

• Has enough power to break down certain food waste
• 3-stage grinding
• Has antimicrobial feature
• Quiet operation
• Auto-reverse function
• Relatively affordable
• Lengthy warranty
• Heavy
• Takes up ample space under the sink
• Needs a separate power cord

InSinkErator SS-100-29 Commercial Waste Disposer – Another Good Option

InSinkErator SS-100-29 Commercial Waste Disposer

Another great option for commercial waste disposal could be the InSinkErator SS-100-29 Commercial Waste Disposer.

Equipped with a 1 HP motor, this machine can shred up to 100 meals at once. It can also operate at a speed of 1725 revolutions per minute. With a continuous feed type, it is sure to efficiently grind up food waste in no time.

The food scraps go through a three-stage grinding process. This ensures that the ground food can pass through the plumbing system smoothly. It boasts superior durability with its corrosion-resistant stainless steel components. The 3/4 in rubber attachment above the grinding chamber absorbs sound and vibration.

What I appreciate about this model is the controlled power airflow. This feature helps cool the motor for efficiency and longer life. It features built-in thermal overload protection, something that even higher-priced models lack. I also like that it has a triple lip seal that safeguards the motor from water damage.

Much like any good foodservice disposers, provides exceptional performance, quiet operation, and optimal energy efficiency.

• Powerful and efficient for shredding 100 meals at a time
• 3-stage grinding
• Durable construction
• Quiet operation
• Built-in thermal overload protection
• Has a triple lip seal against water damage
• Short warranty

A Buyer’s Guide in Finding the Best Commercial Garbage Disposal

Finding the right unit involves a lot of research. Keep in mind that the model you pick will still be determined by factors such as your business’ demands and budget. Here are some general pointers for choosing the ideal machine for you.


Choosing the size of a unit is a matter of how much capacity you want it to have in relation to the type of sink you have. You have to double-check that your preferred model will fit in your sink. I suggest that you measure up the space under your sink.

The horsepower will often give you an idea of the capacity and size of the commercial disposal. This means the higher the horsepower, the larger the unit.

Horsepower (HP)

This is arguably one of the most important factors to keep in mind. The amount of power output by a machine is linked to the volume and kinds of food it can chew.  With a greater HP, it can grind tougher food waste. And it can also grind a lot more food waste at once.

When choosing a commercial garbage disposal, you shouldn’t go for one with less than 1 HP. I recommend getting a machine with 1HP or more for intensive operation.

Different Horsepowers Available:

Commercial disposals are available in a range of motor sizes. You should acquire one that can manage all of your food waste efficiently, depending on the size of your business and usage. You may refer to the different horsepower rates below.

Lower than 1 HP

Models with less than 1 HP are the least powerful. While many domestic disposals have this power rating, most are not designed to fulfill commercial demands. Such machines are often more compact and are perfect for small delis and fast-food restaurants.

1 HP

This is an ideal power rate for commercial garbage disposal. Although they are a little more pricey, they are definitely worth it if your restaurant throws out 100 or more meals every day. A 1 HP commercial waste disposal offers smooth operation, minimal jamming, and a longer lifespan.

1.5 HP

Most commercial garbage disposals have this power rating. With a 1.5 HP machine, you can discard 100 to a few thousand meals a day. They are perfect for large-scale restaurants and hotels.

Higher than 1.5 HP (up to 3 HP)

Many commercial waste disposals are equipped with a 3 HP motor. With machines having more than 1.5 HP, jamming is quite minimal, and the process runs smoothly. These machines are so powerful that they can grind up even the toughest of food waste like bones.

If you own a large restaurant or an extremely busy cafe, these power ratings will be capable of chewing everything you toss at them like it’s nothing.

Grinding Speed Ratings (RPM)

Each appliance, like the motor power, has a specific speed restriction for discarding food waste. The revolutions per minute (RPM) of various garbage disposals vary. The best commercial waste disposal should have at least a speed range of 1725 to 2800 RPM.

Feed Type: Continuous Feed vs. Batch Feed

Commercial garbage disposals are available in two types of feed: continuous feed and batch feed.

The continuous feed is very useful for commercial settings. In comparison to its competitor, the continuous feed garbage disposal is the ideal option for a machine that is simple and convenient. It enables you to discard food waste continuously while cleaning.

Continuous feed garbage disposals also permit any amount of food in one go. You need to be careful in using such types of units, though. It’s not suitable if you have kids at home.

The batch feed disposals, on the other hand, allows you to load the chamber to a certain amount at a time. And it only works when it reaches a certain amount of capacity, splitting the process into batches.

You may find it extremely inconvenient, because you may have to wait for it to reach its maximum capacity before it can discard the waste.

However, a batch feed disposal system often has great safety features, which makes them suitable for households with children. To ensure that the motor operates safely, you must put the cover into the sink opening.

Grinding Chamber and Shredding Blades

The grind chamber is where the magic happens as the shredding blades pulverize the food scraps that you throw in them. So, you’ll want to opt for durability and resilience in order to crush the food more effectively and more finely.

Stainless steel is tough and long-lasting. And it prevents rust from occurring. Even so, choose galvanized steel grind elements with caution. These blades are fairly durable but prone to corrosion. But you can also go for thermoplastic polymers. Which is another widely used material that defies corrosion while staying durable.

Auto-Reverse (Anti-Jam)

Investing in commercial trash disposal with auto-reverse is definitely worth the extra cost. This feature allows the machine to shift the grind pattern. Some models reverse the grind automatically if it senses a jam. Others will feature a button or a hex wrench to reverse them.

Sadly, many commercial waste disposals lack this functionality. This feature will make grinding food waste easier and protects your waste disposal. 

Noise Reduction Feature

Commercial kitchens tend to get noisy with all the appliances housed in one space. And the last thing you want is another appliance that can add to the noise. In this case, consider one with a noise-reduction feature. Most of the noise comes from vibration from the disposal unit to the sink or countertop, as well as the grinding itself.

The best commercial garbage disposals are often equipped with some form of a sound barrier or sound-reduction technology to avoid interfering with interactions between your kitchen staff. It may not completely mute the noise. But they can make the workplace less noisy.

Water-Saving Mode

Some of the best commercial garbage disposals are efficient at minimizing water consumption. Getting a unit with a water-saving control system minimizes the quantity of water required to grind the food properly. Your machine will be using less water when you use your garbage disposal. Which will save you money in the long run.


The longevity of the warranty is a good indication that the manufacturer is confident in their product. It not only testifies to the reliability of the machine but also provides you with additional peace of mind in your investment.

Some manufacturers offer a 12 to 18 months warranty, others even include a lengthy warranty of 7 to 12 years. You should think about how long you wish to use your unit.


The price of a garbage disposal can vary based on the brand. You’ll find reliable garbage disposals between the $500 and $2500 price ranges. Some models even cost under $500. Other high-end and heavy-duty models, on the other hand, can cost you at least more than $5000.

Commercial garbage models are generally on the expensive side. So, it’s important that you have a planned budget for a unit.

Best Commercial Garbage Disposal FAQs

What is a commercial garbage disposal?

A commercial garbage disposal is the same as the household disposal you would have at home. Just bigger and more powerful.

Installed under the sinks, it works in the same manner: shredding food waste into little pieces so it can smoothly pass through the plumbing system. It runs through electricity and often has 1 HP up to 3 HP power ratings. They are equipped to handle larger volumes of food waste in restaurants, hotels, and coffee shops.

How much is the estimated cost of running commercial waste disposal?

Operational expenses vary based on how you use your garbage disposal, as well as the disposal itself. Here are some general guidelines:

Electricity usage

Obviously, the more often you operate the machine, the higher your electric bills will get. But you can lessen your expenses by running your unit only when there’s enough food waste collected. This lets you grind a large quantity of food waste rather than numerous small volumes.

Water usage

Water consumption varies by model and usage. Garbage disposals with 2 HP or less typically consume 5 gallons of water per minute (GPM) while running. Models with 3HP 3-hp or higher may use 8 GPM of water.

What are the alternatives to commercial garbage disposals?

Garbage disposal is excellent for commercial settings since it reduces labor costs by more than half. But it’s also a known fact that commercial garbage disposals can cost a hefty price. And not all businesses, particularly the small ones, can afford a commercial unit. Luckily, there are alternatives you can try.

Use a Drain Strainer

While it doesn’t shred the food to reduce waste like garbage disposal, this should keep the drainage from being clogged. A drain strainer won’t allow kitchen appliances to enter and keeps the food from sliding down the drainage.

The only thing you’ll have in the drainage is water. If you use waste disposal to avoid drainage clogs, this is a less expensive choice. However, if you also wish to degrade the food, a drain strain won’t suffice.


Composting is an eco-friendly way of discarding waste like food or plant material. You can build your own compost pit or, if accessible, you can choose a community compost. It’s where you will dispose of all food waste.

Microorganisms will then break down the material, changing it into compost that may be securely kept, handled, and repurposed to help the planet.

Recycling Plants

Several localities have built recycling plants to repurpose food waste. This entails sorting the trash into food waste and recyclables. Also, you won’t have any clogging issues if you take them to the facility. These materials are often recycled into soil improvers or fertilizers.

​​How long should commercial garbage disposal last?

Garbage disposals usually last between 8 and 15 years, depending on how they are used. Proper care and maintenance can also extend their lifespan.

Is higher horsepower better for garbage disposal?

Commercial food waste disposers are more efficient with higher horsepower. This means minimal jams and finer food waste. A 3 horsepower motor, for instance, will provide more grinding power than a 1.5 horsepower motor.


The InSinkErator Evolution Excel Garbage Disposal made it to the top of my list because it offers quiet operation despite having a high power-rating at 1HP. It’s durable and works smoothly with a jam-assist feature and three-stage grinding.

For large-scale restaurants, you may consider the Waste King 3000-3 Commercial Food Waste Disposer. It’s equipped with 3 HP and has a durable construction.

This commercial waste disposer also comes with a noise-reducing mechanism. But what I like the most are the durable backup blades and the less overheating mechanism.

If you’re looking for a unit that’s easy to install, the InSinkErator 79024-ISE Garbage Disposal could make replacing your old unit a breeze. With 1 HP, this powerful garbage disposal has enough muscle to break through tough food waste. And because it’s in a compact size, it may fit through most under sinks.

The InSinkErator PRO1100XL Pro Series could also be a wonderful choice for decent pulverizing. With 1.1 HP, it has enough power to break down certain food waste – thanks to its three-stage grinding, too!

What I like about this model are the antimicrobial feature, auto-reverse function, and fairly affordable price. It also offers a quiet operation.

Another good option would be the InSinkErator SS-100-29 Commercial Waste Disposer. This InSinkErator is equipped with 1 Hp that is powerful and efficient for shredding 100 meals at a time. It’s another three-stage grinding weapon to break through tough food waste.

This commercial garbage disposal boasts durable construction and quiet operation. The built-in thermal overload protection is good to highlight since it saves the motor. It also has a triple lip seal that protects it against water damage.

I hope you’ve found the best commercial food waste disposal from my list, and make sure to check out their latest prices and discounts. Good luck!
