Do compost bins emit odors?

Compost bins are a popular choice for those looking to reduce waste and create nutrient-rich soil for their gardens. However, one concern that often arises is whether compost bins emit odors. In this article, we will explore the various opinions and information provided by experts to answer this question.

Opinions and Information

There are varying opinions on whether compost bins emit odors. Some sources suggest that compost bins do give off a little odor, but a correctly maintained compost bin shouldn’t have a strong or unpleasant smell. On the other hand, other sources state that compost bins can smell if not properly maintained or if certain types of food waste are added.

According to Lomi, a composting company, compost bins should not smell if they are done correctly. They argue that smelly compost is a sign that something went wrong in the composting process. Similarly, Gardening Know How suggests that compost bins can be odorless if they are properly managed. They emphasize the importance of balancing the nitrogen and carbon in the material, keeping the pile moderately moist and aerated, and avoiding certain food items such as meat.

However, other sources, such as The New York Times, Compost Magazine, and Help Me Compost, state that compost bins are not necessarily odorless. These sources provide tips and recommendations for preventing or minimizing odors.

Preventing Odors

To prevent odors from compost bins, it is important to follow proper composting practices. Here are some tips that experts recommend:

  • Ensure sufficient oxygen by providing proper airflow in the compost pile.
  • Maintain a good balance of green materials (nitrogen-rich) and brown materials (carbon-rich) in your compost.
  • Avoid excess moisture by keeping the compost pile damp, but not overly wet.
  • Layer the compost properly, alternating between brown and green materials.
  • Avoid adding smelly waste such as meat or dairy products to the compost.

Additionally, using odor-free compost bins like Lomi, an electric composter, or compost tumblers can help prevent odors.


Based on the information provided, it can be concluded that compost bins can emit odors if not properly maintained or if certain food waste is added. However, with proper management, compost bins can be odorless or have minimal odor. The key to preventing odors is to maintain a careful balance of nitrogen and carbon in the compost, provide sufficient airflow, avoid excess moisture, and avoid adding smelly waste.
