Composting in an apartment may sound like a challenge, especially if you’re concerned about smells or space limitations. However, composting can be done in a way that’s clean, easy, and doesn’t take up much room — even in a small apartment. Plus, it’s one of the most eco-friendly things you can do to reduce waste and enrich your plants. In this guide, we’ll walk you through how to compost in your apartment with zero smell, providing you with practical tips and tools to make the process as simple and odor-free as possible.
Why Compost in Your Apartment?
Composting is an excellent way to reduce the amount of waste that ends up in landfills, turning organic scraps into nutrient-rich compost that can be used for gardening. Even in an apartment, you can make a difference by composting food scraps, coffee grounds, and other organic materials. Here’s why composting in your apartment makes sense:
- Waste Reduction: Organic waste, like fruit and vegetable scraps, takes up a significant portion of landfill space. Composting reduces this burden.
- Natural Fertilizer: Homemade compost is a great way to enrich your plants with nutrients, especially if you’re into indoor gardening or vertical gardening.
- Eco-Friendly Living: Composting helps you contribute to a more sustainable, zero-waste lifestyle. It’s a small change that can have a big environmental impact.

Step 1: Choose the Right Composting Method for Your Apartment
When it comes to composting in an apartment, you have several methods to choose from. To ensure that you’re not dealing with unpleasant smells, selecting the right composting method is crucial.
1.1. Vermicomposting (Worm Composting)
Vermicomposting is one of the most efficient ways to compost in a small space without producing any odor. It involves using worms, typically red wigglers, to break down food scraps. The result is nutrient-rich compost and a minimal amount of smell if the process is done correctly.
Why it’s great for apartments:
- Minimal space needed: A small bin or container is enough.
- Odor-free: Worms do most of the work without creating unpleasant smells.
- Efficient: Reduces waste quickly and produces high-quality compost.
How to start:
- Purchase a worm composting bin or make your own with a plastic storage bin.
- Add bedding, such as shredded newspaper or coconut coir, to create a comfortable environment for the worms.
- Add food scraps (but avoid meat, dairy, and oily foods) and keep the bin moist, but not too wet.
- Harvest the compost every few months, separating the worms and fresh compost.
1.2. Bokashi Composting
Bokashi composting is another excellent method for apartment dwellers. This fermentation-based method involves using a special mix of microorganisms to break down food scraps in an airtight container.
Why it’s great for apartments:
- Compact: The Bokashi bin is small and can be kept under your kitchen sink or in a closet.
- Odor-free: The process doesn’t produce foul odors, only a faint, slightly sweet smell due to fermentation.
- Fast: Food waste breaks down in just a few weeks.
How to start:
- Purchase a Bokashi composting kit, which includes a bucket, fermenting bran (inoculated with microorganisms), and instructions.
- Collect food scraps and add them to the bin with a layer of Bokashi bran after each addition.
- Keep the bin sealed and let it ferment for about two weeks. Once full, bury the contents in soil, or allow it to further compost in a traditional compost bin if you have one.
Step 2: Properly Manage Your Compost to Avoid Smell
No matter which composting method you choose, proper maintenance is key to preventing odors. The most common cause of smell in composting is an imbalance of materials or excessive moisture. Here are some tips to keep things smell-free:
2.1. Balance Your Green and Brown Materials
Composting requires both “green” materials (such as food scraps, coffee grounds, and grass clippings) and “brown” materials (like shredded paper, dry leaves, or cardboard). A good balance is essential for odor control and proper decomposition.
- Green Materials: These are rich in nitrogen and include items like fruit and vegetable scraps, coffee grounds, and tea bags.
- Brown Materials: These are rich in carbon and include dry leaves, shredded newspaper, cardboard, and sawdust.
The general rule is to have more brown materials than green, as this helps to avoid excessive moisture and prevents the compost from becoming too smelly.
2.2. Maintain Proper Moisture Levels
Compost should be moist but not soggy. If it’s too wet, it can become a breeding ground for odor-causing bacteria. To maintain the right moisture level:
- Add dry materials (like newspaper or cardboard) if the compost feels too wet.
- Keep the bin in a well-ventilated area to avoid excess moisture buildup.
If you’re using a worm bin, avoid adding too many wet items like watermelon rinds or overly wet food scraps.
2.3. Aerate Your Compost
Compost needs air for aerobic bacteria to break down the material efficiently. Lack of airflow can lead to anaerobic conditions, which cause foul odors. Regularly aerate your compost by:
- Stirring the materials with a compost turner (for Bokashi or traditional composting).
- Gently shaking or stirring your worm composting bin.
Aeration also helps to speed up the decomposition process, reducing the risk of smells.
Step 3: Set Up a Composting Station in Your Apartment
Now that you’ve chosen the right composting method and learned the basics of smell prevention, it’s time to set up your composting station.
3.1. Find the Right Spot for Your Compost Bin
- Vermicomposting: Choose a cool, dark place like a basement, closet, or under the sink. Keep the temperature between 55-77°F (13-25°C) for optimal worm health.
- Bokashi Composting: This system can be kept in a cupboard or under your sink. Make sure it’s in a spot that’s easy to access but won’t disturb your daily activities.
3.2. Keep a Compost Bin for Scraps
Keep a small, odor-free container in your kitchen for collecting food scraps. Look for a compost bin with a tight-fitting lid and charcoal filters to trap odors. You can easily empty the contents into your larger composting system once it’s full.

Step 4: Troubleshooting Smelly Compost
Even with the best efforts, you may encounter the occasional odor problem. Here’s how to fix common issues:
4.1. Too Wet?
If your compost smells sour or rotten, it might be too wet. Add more brown materials (cardboard, dry leaves, shredded newspaper) and mix well to absorb the moisture.
4.2. Too Dry?
If your compost smells like ammonia, it may be too dry. Add some water or green materials to bring moisture back into balance.
4.3. Too Much Food Scraps?
If the compost smells because there’s an overload of food scraps, you may need to add more brown materials or reduce the amount of food waste you add.
Step 5: Using Your Finished Compost
Once your compost has fully decomposed, you’ll have rich, dark compost that’s perfect for enriching the soil of your indoor plants or garden. If you don’t have plants, consider donating the compost to a community garden or giving it to a friend with outdoor space.
Final Thoughts
Composting in an apartment is entirely possible with the right method, a little patience, and some simple practices. Whether you choose vermicomposting, Bokashi composting, or a traditional indoor composting system, you can easily manage waste and contribute to a more sustainable lifestyle. And the best part? It doesn’t have to smell!
