Garbage Disposal vs. Compost Bin

One of the biggest challenges that people face is the disposal of waste. While some waste can be disposed of in the kitchen garden, some waste does not decompose, and as a result, it requires proper disposal to prevent environmental problems. Some of the most common methods include garbage disposal and compost bin.

The two ways of garbage disposal have several similarities and differences. But the question is, among the two which should you try out? Let us try to find out. In this article, we are going to focus on garbage disposal vs compost bin by looking at the two and pointing out the similarities and differences.

Garbage Disposal

The garbage disposal refers to a bin that is installed under the sink in the kitchen. The device is electrically powered, and it is usually fitted in between the trap and the sink drain. It contains a unit of disposal that shreds the food remains into fine pieces that can be passed through plumbing.

The disposal has a spinning disk and an impeller plate that turns it rapidly. The movement turns the food remains against the external wall of the chamber that grinds it. Then, the tiny pieces are washed through the holes on the chamber walls.

Although there are two blades on the impeller, they are not as sharp as you may tend to think.

The Compost Bin

The compost bin is a container used to provide a home and to process compost into some organic manure for use within the garden. The bins are made to decompose organic waste. For this reason, the compost bin contains aeration holes and a moisture retention mechanism. The presence of air and moisture hastens the decomposition process. If air and moisture are not present, aerobic organisms cannot survive; hence, no decomposition can take place.

It is true that even if the waste is heaped in the open, decomposition will still take place. However, the compost bin fastens the rate of decay. Besides, the bin prevents rodents like rats to find their way in.

Bins come in different shapes and sizes. It all depends on the kind of bin you want.


  • Environment-friendly
  • Can be set up with a low budget
  • Anyone can do it
  • Improves soil structure
  • Improves water retention
  • Serves as natural, organic fertilizer


  • Nutrient imbalance
    (30:1 ratio of carbon to nitrogen is required. Nitrogen is supplied by grass clippings, fruit and vegetable scraps, coffee grounds and teabags, while carbon comes from dry leaves, wood ash, sawdust, and shredded paper.)
  • Health and safety concerns
    ( never add meat or bone scraps, fatty foods, like oils, cheese, and whole eggs, to compost)
  • Needs maintenance
  • Not all food waste can go in the compost bin (read our post “What can you put in a compost bin?“)

Garbage Disposal vs a Compost Bin: Differences

Although both the garbage disposal and the bin are meant for waste management, the two have several variations. In this section, we are going to focus on garbage disposal vs compost.

To start with, the garbage disposal unit is housed inside your kitchen. As we have already established, the disposal is fitted on the sink or somewhere over your drain. For this reason, it also serves as your second drain. On the other hand, the compost bin is kept outside of the house or the kitchen.

Secondly, we can look at the difference in the way the two waste bins work. The garbage disposal takes in the food remains and slices them into fine particles. Afterward, they are drained using water, and they eventually end in the sewer system. Consequently, the garbage disposal becomes environmentally friendly. On the other hand, the compost bin keeps the debris until they start decomposing to get ready for the garden. They work completely differently.

Garbage Disposal and a Compost Bin: Similarities

While the two have some differences, they also have some similarities.

Firstly, the two devices serve a common function. Of course, both of them are used to get rid of waste. Depending on the affordability and size of the kitchen, you can either choose to keep your waste inside the garbage disposal or move it outside to the compost bin. They serve a uniform purpose.

Besides, the two methods of waste disposal are environmentally friendly. The waste that ends on the garbage disposal ends in the sewer system. In this way, the waste does not lead to pollution of the environment. Similarly, the debris that lands in the compost bin decomposes and enriches the soil.

To wrap up, both the garbage disposal and the compost bin are significant in managing waste within your homestead. However, depending on several factors like space, purpose, and cost, you can go for what you would like. The baseline remains that both are friendly to the environment, and they address a similar problem.

You can have an in-depth evaluation of the two and know what will assist in keeping your environment clean.
