Living in an apartment doesn’t mean you have to give up on composting or sustainable waste management. With the right approach, you can turn kitchen scraps into nutrient-rich compost without worrying about unpleasant odors or pests. This guide will walk you through practical steps for how to compost in apartments while keeping your living space fresh and clean.
Composting indoors is not only possible but can also be surprisingly simple. By choosing the right method and following a few best practices, you’ll be able to recycle food waste efficiently, support your indoor plants, and contribute to a greener lifestyle. If you’re interested in maximizing your small-space gardening efforts, you might also find value in learning about small-space gardening mistakes to avoid.
Choosing the Right Indoor Composting Method
The first step to odor-free composting in a small space is selecting a method that fits your lifestyle and available room. Here are the most popular options for apartment dwellers:
- Bokashi bins: This fermentation-based system uses a special bran to break down food waste quickly and with minimal smell. Bokashi bins are compact and can handle a wide variety of kitchen scraps, including meat and dairy.
- Vermicomposting (worm bins): Red wiggler worms process food scraps into rich castings. With proper care, worm bins are nearly odorless and can be kept under the sink or in a closet.
- Electric composters: These countertop appliances accelerate decomposition using heat and aeration. They are fast, clean, and ideal for those who want a low-maintenance solution.
Each method has its benefits. Bokashi is great for those who want to compost all types of food waste, while vermicomposting is perfect for gardeners looking to create high-quality soil amendments. Electric composters offer convenience but may require a higher upfront investment.
Setting Up Your Apartment Compost Bin
Once you’ve chosen your method, it’s time to set up your composting system. Here’s how to get started:
- Select a suitable container: Use a bin with a tight-fitting lid to prevent odors and keep pests out. For worm bins, ensure there’s adequate ventilation and drainage.
- Choose the right location: Place your compost bin in a spot that’s easy to access but out of direct sunlight. Under the kitchen sink, on a balcony, or in a utility closet are all good options.
- Prepare the bedding: For vermicomposting, start with moist shredded newspaper, cardboard, or coconut coir as bedding for the worms. Bokashi bins require a layer of Bokashi bran at the bottom.
- Add food scraps: Chop scraps into small pieces to speed up decomposition and reduce the risk of smell.
- Maintain balance: Alternate between “greens” (fruit and veggie scraps, coffee grounds) and “browns” (paper, dry leaves) to keep the compost healthy and odor-free.
Tips for Odor-Free Composting Indoors
Keeping your compost bin fresh is all about balance and maintenance. Here are some essential tips to prevent unwanted smells:
- Keep it moist, not wet: Compost should feel like a wrung-out sponge. Too much moisture leads to anaerobic conditions and odor.
- Cover food scraps: Always add a layer of browns (paper, dry leaves, or coconut coir) on top of new scraps to absorb moisture and control smell.
- Avoid problematic items: Don’t add oily foods, large amounts of citrus, or pet waste. These can slow decomposition and produce odors.
- Stir or aerate regularly: Mixing the compost introduces oxygen, which helps break down materials and keeps the process aerobic and odorless.
- Monitor for pests: If you notice fruit flies or gnats, bury food scraps deeper and ensure the lid is sealed.

What to Compost and What to Avoid in Small Spaces
Not all kitchen waste is suitable for indoor composting. Here’s a quick reference to help you decide what goes in your bin:
| Compostable Indoors | Avoid Indoors |
|---|---|
| Fruit and vegetable scraps | Meat, fish, and bones (except Bokashi) |
| Coffee grounds and filters | Dairy products (except Bokashi) |
| Tea bags (without staples) | Oily or greasy foods |
| Eggshells (crushed) | Pet waste |
| Shredded paper, cardboard | Large amounts of citrus peels |
Following these guidelines will help keep your compost healthy and odor-free, making it easier to manage in a compact environment.
Using Finished Compost in Your Apartment Garden
Once your compost is dark, crumbly, and earthy-smelling, it’s ready to use. Here’s how to make the most of your homemade compost in an apartment:
- Top-dress houseplants: Add a thin layer to the surface of your potted plants to boost soil nutrients.
- Mix into potting soil: Blend finished compost with store-bought soil for container gardens or balcony planters.
- Share with neighbors: If you have more compost than you need, offer some to fellow gardeners in your building or community.

Common Challenges and Solutions for Apartment Composting
Even with the best setup, you might encounter a few hurdles. Here’s how to address the most frequent issues:
- Bad smells: Usually caused by too much moisture or not enough browns. Add more dry material and stir the compost.
- Fruit flies: Bury food scraps under browns and keep the lid tightly closed.
- Slow decomposition: Chop scraps smaller, maintain moisture, and aerate regularly.
- Limited space: Use compact bins and compost only what you can manage. Donate excess food scraps to local community gardens if possible.
