What Are The Benefits of Garbage Disposals?

Putting your food waste down the drain is a modern convenience that they offer because of their ability to grind food into small pieces which won’t clog your drains. But that’s not all you can get from a garbage disposal. Here are a few reasons why they are awesome:

1. Better Environment

A garbage disposal unit shreds all particles and sediments in your sink, so it creates a better living environment since you won’t have rotting waste all over your kitchen and yard. Additionally, it is better hygiene for the home, without the health hazards or stink from the toxic and contaminating smell. With them, you will enjoy a better household. 

What’s even better is that by passing those small scraps of food into the waste disposal unit, you will save a bag of trash from filling the landfill.

2. Quicker Cleanup

Let’s face it; no one wants to take out trash filled with the wet gunk from food or other waste items. By using this unit to shred and flush down leftover bits and smelly sediments of food, you will have an easier time cleaning up the dishes and segregating trash in your house.

Besides, no roaches or bugs will come in your way if you pulverize your kitchen waste rather than put it in the trash can, which attracts pests. You will no longer have bacteria or need a garbage can below your kitchen sink, which smells and looks icky with time.

3. Less Stink In Your House

Since you’ll no longer throw kitchen dirt and food waste in the trash, you will have little to worry about the odor or amount of rotting garbage wafting in your home. The neighborhood won’t scrunch their noses in disgust as well.

4. Fewer Plumbing Problems

For most households, blocked kitchen sinks and drains are a nightmare especially when they’re not careful with what they wash or send down the drain. With a good garbage disposal, however, you will not have clogged sinks or plumbing problems because all food waste is ground into small particles that go down the drain smoothly.

How To Select a Garbage Disposal for Your Kitchen?

Before choosing a unit, here are a few things to consider:

1. Type of Unit

Garbage disposals come in two types; continuous-feed and batch-feed, which simply indicates the way you load food waste into the grinding chamber.

  • Continuous-feed: Just as the name suggests, this type of garbage disposal operates continuously, letting you turn it on and load your food waste gradually while it’s running. This model is easy to use because you can add new food waste as the old waste is ground and sent down the drain.
  • Batch-feed: This unit grinds food waste in small batches and is a safer option for families with curious kids. A stopper is secured in place before running this unit. With this type of disposal, you only run one load of waste at a time. Although the size of the grinding chamber varies with the manufacturer, you’ll typically grind up to 4 cups of food waste at a time.

2. Power options

The more powerful your unit is, the more efficiently it grinds your food waste. Here are the common power options for your garbage disposal:

  • 1/3 Horsepower: Although they are the most economical units, they are the weakest and often clog when grinding the fibrous foods.
  • ½ Horsepower: This disposal is a bit stronger than its predecessor and is ideal for a mid-size household that has more food waste.
  • ¾ Horsepower: With this unit, you get more power and technology to easily chew through fibrous foods and bones without any clog. It is the right choice for a household with a large family and substantial food waste.
  • 1-2 Horsepower: This powerhouse endures all heavy use and grinds through every food waste thrown its way without jamming. And you must part with anything between $150 and $500 to own this workhorse.

3. Plug-in Vs. Direct-Wired

A majority of garbage disposal units are designed to wire directly into a home’s electrical wiring system. However, there are a few models with a power cord to plug into an electrical outlet below the sink. Models that lack attached plugs could be transformed into plug-in models by buying optional plug-in cords.

While it’s entirely your choice to install either a plug-in or direct wired disposal, it is advisable that confirm with the local building authority about any regulations or codes you must adhere to. A direct-wired unit requires professional installation while the plug-in unit is rather straightforward to install.

4. Size

A higher horsepower translates into a bigger motor, and this will obviously increase the size of your garbage disposal. You need to consider the size of your unit if there’s limited space below your kitchen sink. If you have a reverse osmosis system, for instance, the space under your sink may be insufficient.

Be sure to measure the space below your sink before settling on a garbage disposal.

5. Noise Factor

Noisy garbage disposals are a huge turnoff for many, but the modern-day models are quieter with some emitting little more than a mere hum. The integration of sound-proofing technology, insulation, and padded mounts to reduce vibration helps reduce the noise produced by it.

You will obviously not see a model’s noise factor on the manufacturer’s manual so a pre-purchase test or reading through customer reviews would help.

6. Anti-Jamming Feature

Grinding blades jam when there’s too much food packed in the unit. A quick fix for this problem would be turning off the machine to remove the jammed food manually. However, some units now come with an anti-jamming feature that detects a clog in the blades and reverses them to clear all waste that is stuck

7. Stainless-Steel Grinding Chamber

Quality garbage disposal units often feature stainless steel grinding components such as a stainless-steel grinding chamber, armature shaft or dual-swivel impellers. This feature purportedly adds to the durability of your unit since it doesn’t give in to touch bone grinds. Besides, stainless steel is corrosion proof and won’t suffer water damage.


For a stink-free kitchen or clog-free drains, you must be sure to dispose of your kitchen waste correctly and the garbage disposal will come in handy. From a better living environment to fewer plumbing problems to quicker cleanup, the benefits of a garbage disposal unit are irresistible.

While there are many products to choose from, the InSinkErator Evolution Compact Continuous Feed is the best pick. We were particularly impressed by its great grinding power, SoundSeal technology to reduce noise, a stainless steel grind chamber, and its continuous-feed mechanism.
