What is a domestic composter?

A domestic composting system is a recycling system for organic waste that works in multiple stages. In the two upper modules, earthworms and microorganisms are responsible for transforming the remains of food into fertilizer.

The lower module is reserved for the leachate, that is, the wet result of this process, which can be discarded or used as a pesticide. Today it is possible to find them in various sizes and models, so it is possible to own a composter even if you live in an apartment.

Pros and Cons

The domestic composter has its advantages. It helps to reduce the disposal of organic waste into landfills. The process results in an excellent quality fertilizer and maintenance is simple, not requiring special care.

There are some disadvantages to be aware of. Some people may have an aversion to having a composter at home. In many cases it is necessary to buy earthworms separately and not every type of organic waste can be disposed of in a composter.

How to use the domestic composter

Using the domestic composter is very simple. First, it is important to cover the bottom of the top two containers  with sawdust (or dry leaves), then add the earth and earthworms on the middle floor.

Once assembled, the food will always be disposed of in the upper tray, and you should mix wet and dry organic remains, always adding a little sawdust to better control the humidity, an essential factor so that the worms do not die.

Over time, they earthworms and naturally forming bacterial colonies will break down the waste. When the compost module is full, replace the upper tray with the middle one, and begin to fill again

When the middle module has adequately decomposed, you will have a nutrient rich fertilizer. Just collect it and transport it with the help of a bucket or wheelbarrow to use in your garden.

What types of waste can go in a composter?

You can put scraps of fruits, fruit peels, vegetables, and dry leaves and sawdust to help control moisture.

Experts do not recommend placing leftover meat, dairy products, or some citrus fruits such as lemon; the high concentration of benzoic acid in some citrus fruits will inhibit bacterial growth (you will see benzoic acid added to many packaged foods as a preservative).

What are the main types of home composters?

There are currently two main types of composters. Vermicomposting uses earthworms, in a more natural process that lasts about two months. These are the cheapest models on the market.

The other is an automatic composter, decomposition is done with the help of microorganisms and added heat, but without earthworms. There is no need to add sawdust or dry materials and the whole process is more rapid taking ony days. These compostors require electrical energy and are significantly more expensive.

How much?

The price can vary a lot according to the type and size of the domestic composter. The most traditional models, by vermicomposting, go between $70 to $150.

An automatic model, or a traditional model with large capacity, vary between  $300 and $500.

Where to buy?

You can find home composters at stores specializing in gardening supplies. However, if you are unable to find the ideal model in your city, most large online retailers carry composters.

Purchasing Criteria

As you can see throughout our article, there are several benefits to owning a home composter, and if you take care of it properly, it is a great way to reduce your carbon footprint.

Here are the main criteria to evaluate before purchse:

  • Material
  • Size and capacity
  • Decomposition time
  • Design


Currently, most composters are produced in plastic. This is because in the old wooden models, deterioration of the material over time and with exposure to bad weather required replacement every few years.

In this respect, plastic is much more durable and resistant. In addition, many companies use recycled material, which lends even more with the purpose of having a sustainable item in your home.

Size and capacity

Before buying a composter, it is important to check its size and capacity. Do you have room in your yard. Many composters are modular, so you can increase the capacity according to your needs. 35 lb models, for example, cover a family with two or three people.

Decomposition time

The decomposition time may vary according to the amount of earthworms and the type of materials wasted. In traditional models, the entire process takes about two months.

In the case of automatic composters, which use only microorganisms, the process is incredibly faster, where it is possible to decompose their maximum capacity in just one day. However, since electrical power is consumed in the decomposition process, this method may not fit into everyone’s goal of reducing their carbon footprint.


Finally, it is also important to pay attention to the design of your composer. Opt for models that fit well in your garden or yard and choose pleasant colors. And, thinking more about practicality, some models have a type of ladder that allows earthworms to access waste more easily.
