How to Start Composting in a Small Apartment — It Is Seriously Not That Hard
When I mention apartment composting to people, I usually get one of two reactions. Either they look at me like I am some kind of eco-warrior monk, or they tell me it is impossible without a backyard. I believed the second reaction myself for years. I thought composting required a big outdoor bin, a yard, and tolerance for smells and fruit flies. None of that is true. I have been composting in a one-bedroom apartment for over a year, and my apartment has never smelled. There are no bugs. My system takes about two minutes of effort per day and produces real, usable compost for my houseplants. Here is exactly how I set it up and how you can do the same thing.
Why I Started Composting
The catalyst was a trash audit. I read about the concept online and decided to track what was actually in my garbage for one week. I was appalled by the results. Roughly forty percent of my trash by volume was food scraps. Banana peels, coffee grounds, eggshells, vegetable trimmings, tea bags, apple cores, bread ends. All of that organic material was going into a plastic bag, being trucked to a landfill, and producing methane as it decomposed anaerobically. I was essentially paying to have perfectly good plant food buried in the ground where it would harm the environment instead of feeding my plants. That realization pushed me to try apartment composting.
Choosing the Right Indoor Composting Method
There are three main methods for apartment composting, and the right one depends on your space and commitment level. The first is vermicomposting, which uses worms to break down food scraps in a small bin. This is the most efficient method and produces excellent compost, but it requires purchasing red wiggler worms and maintaining their habitat. The second is Bokashi composting, a Japanese method that uses beneficial microorganisms to ferment food scraps anaerobically. It handles all food types including meat and dairy, which traditional composting cannot. The third is a simple electric countertop composter, which dehydrates and grinds food scraps into a dry, usable amendment in hours.
I started with vermicomposting because it was the most affordable and most rewarding option. A basic worm bin costs about thirty to fifty dollars online, or you can make one from two plastic storage tubs for about ten dollars. The worms cost roughly twenty to thirty dollars and are shipped to your door.
Why this works: Red wiggler worms are incredibly efficient processors. A pound of worms can consume roughly half a pound of food scraps per day. The bin takes up about two square feet of floor space and produces no odor when maintained properly. The finished compost, called vermicast, is one of the richest soil amendments available and dramatically improves plant health.
Setting Up a Simple Worm Bin
Here is the exact setup I used. I bought two plastic storage tubs, roughly ten gallons each, from a dollar store. One tub is the bin, the other is a drainage collector underneath. I drilled about twenty small holes in the bottom of the top tub for drainage and a row of small holes near the top for ventilation. I placed the top tub inside the bottom tub, elevating it on a few small blocks so liquid can drain into the bottom tub.
For bedding, I shredded newspaper and cardboard into strips, moistened them until they felt like a wrung-out sponge, and filled the bin about six inches deep. I added a handful of garden soil to introduce beneficial microorganisms. Then I added my worms and let them settle in for a day before feeding them. The entire setup took about thirty minutes.
Why this works: The bedding provides carbon, moisture, and structure for the worms to move through. The drainage holes prevent the bin from becoming waterlogged, which would create anaerobic conditions and odor. The ventilation holes ensure adequate airflow, which the worms need to survive and thrive. The two-tub system catches excess liquid, called worm tea, which is an excellent liquid fertilizer for houseplants.
What to Feed Your Worms
Worms eat most fruit and vegetable scraps, coffee grounds and filters, tea bags without staples, crushed eggshells, bread and grains in moderation, and small amounts of crushed yard waste like dry leaves. I keep a small countertop container, a stainless steel bowl with a lid, on my kitchen counter for collecting scraps throughout the day. At the end of each day, I dump the bowl into the worm bin, bury the scraps under the bedding in one corner, and cover with fresh bedding.
What NOT to feed worms includes meat, dairy, oily foods, citrus in large quantities, onion and garlic peels in excess, and anything synthetic or treated with pesticides. These items either attract pests, create odors, or harm the worms.
Why this works: Burying food scraps under bedding prevents odor and fruit flies because the decomposition happens below the surface where it is dark and contained. The worms migrate toward the food, consume it over several days, and convert it into nutrient-rich vermicast. Rotating feeding locations within the bin ensures even processing and prevents overloading any single area.
Harvesting the Compost
After about three to four months, the bedding will be mostly consumed and replaced with dark, crumbly, earthy-smelling compost. To harvest, I use the light method. I move all the bin contents to one side and place fresh bedding and food on the empty side. Over the next two weeks, the worms migrate toward the fresh food. I then remove the compost from the old side, which should be mostly worm-free. Any remaining worms I pick out by hand and return to the bin.
The finished compost goes into my potted plants as a top dressing. I mix about a quarter cup into the top inch of soil in each pot. The difference in plant health is noticeable within weeks. My pothos and spider plants grew visibly faster and produced greener leaves after I started adding vermicast.
Why this works: The light method leverages worms’ natural aversion to light. They will consistently move away from exposed areas into dark, fresh bedding. This allows you to separate finished compost from the active bin without manually sorting through the contents.
Common Mistakes I Made and How to Fix Them
My first mistake was overfeeding the worms. In my enthusiasm, I added too many scraps at once, which created heat and a sour smell. The fix was simple: I stopped feeding for a week, added fresh bedding, and let the worms catch up. The second mistake was not chopping food scraps into small pieces. Whole banana peels take weeks to decompose, but chopped peels disappear in days. Now I chop everything into roughly one-inch pieces before adding it to the bin. The third mistake was letting the bin dry out. Worms need consistent moisture, so I check the bedding weekly and spray it with water if it feels dry.
I also initially placed the bin in a dark, poorly ventilated corner, which caused moisture buildup. Moving the bin to a brighter, better-ventilated area with indirect light solved the problem immediately.
The Bokashi Alternative
If worms make you uncomfortable, Bokashi is an excellent alternative. You need a Bokashi bucket, which has a spigot for draining liquid, and Bokashi bran inoculated with beneficial microorganisms. You layer food scraps with the bran, press it down to remove air, seal the bucket, and let it ferment for two weeks. The process produces no odor because the fermentation is anaerobic and the beneficial microbes outcompete odor-causing bacteria. After fermentation, you bury the contents in soil or add them to a traditional compost bin to finish decomposing.
Why this works: Bokashi fermentation pre-digests food waste using lactic acid bacteria, yeast, and phototrophic bacteria. The fermented material breaks down much faster when mixed with soil than raw food scraps. Bokashi handles all food types, including meat and dairy, making it more versatile than worm composting.
Final Thoughts
Apartment composting is one of the most rewarding eco-friendly habits I have adopted. It diverts hundreds of pounds of food waste from landfills each year, produces free fertilizer for my plants, and takes less than five minutes of daily effort. The smell concern is a non-issue when the system is maintained properly. My guests do not even know I have a worm bin unless I show them. Whether you choose vermicomposting, Bokashi, or an electric composter, the important thing is to start. Food waste is a problem we all contribute to, and apartment composting is a surprisingly simple solution. Give it a try. I genuinely believe you will be amazed at how easy and satisfying it is.
