Composting for Small Apartments: Genius Tips to Go Green

Quick Section

Living in a small apartment doesn’t mean you have to miss out on the amazing benefits of composting. You can still reduce your landfill waste, create nutrient-rich soil for your houseplants, and feel good about doing your part for the planet. It’s not as complicated or messy as you might think! Troy D Harn here, your go-to guy for making home projects easy and accessible. I’m going to walk you through everything you need to know to get started with composting, no matter how little space you have. We’ll cover the best methods, the gear you’ll need, and some insider tricks to make it smell-free and stress-free.

Why Compost, Even in a Tiny Space?

Composting is a fantastic way to give back to the earth. When you compost, you’re essentially recycling organic materials—like food scraps and yard waste—into a dark, crumbly, nutrient-rich soil amendment. This “black gold” supercharges your plants, helps soil retain moisture, and reduces the need for chemical fertilizers. For apartment dwellers, it’s a smart way to minimize household waste, as food scraps often make up a significant portion of what we throw away. Plus, it’s incredibly satisfying to see your kitchen cast-offs turn into something valuable for your potted plants or balcony garden.

It’s also a surprisingly simple process once you understand the basics. Think of it as nature’s ultimate recycling program, happening right in your own home. You’ll be surprised how much you can divert from the trash bin with just a little effort.

Choosing the Right Composting Method for Your Apartment

The biggest hurdle for apartment composting is space. Luckily, there are several methods designed specifically for smaller living situations:

1. Worm Composting (Vermicomposting)

This is one of the most popular and effective methods for apartment dwellers. It uses red wiggler worms to break down food scraps. It’s relatively fast, odor-free if done correctly, and produces a nutrient-dense compost called worm castings.

How it works: You set up a bin with bedding material (like shredded newspaper or coconut coir), add your food scraps, and introduce red wiggler worms. The worms eat the scraps and their waste becomes vermicompost.
Pros: Compact, efficient, produces high-quality compost, minimal odor, can be done indoors.
Cons: Requires managing live creatures (though they’re low maintenance!), initial setup cost for worms and bin.
What you need:

A worm bin (you can buy one or DIY with plastic storage bins)
Bedding material (shredded newspaper, cardboard, coir)
Red wiggler worms (not earthworms from your garden!)
Kitchen scraps (see “What to Compost” section)

For more detailed guidance on setting up your worm bin, check out resources from university extension offices, like this helpful guide from the University of New Hampshire Extension.

2. Bokashi Composting

Bokashi is a unique fermentation process that pickles your food waste rather than rotting it. It uses a special Bokashi bran inoculated with effective microorganisms (EMs) to anaerobically ferment the waste. It can handle a wider range of scraps than worm composting, including meat and dairy.

How it works: You layer food scraps in an airtight Bokashi bucket, sprinkling Bokashi bran over each layer. The microbes ferment the waste. After a few weeks, the fermented material is buried in soil (or added to a traditional compost pile) to finish decomposing. For apartment dwellers, you can often find community gardens or local composting services that accept Bokashi-fermented waste.
Pros: Can compost meat, dairy, and oily foods; compact system; produces a nutrient-rich liquid “tea” that can be diluted and used as fertilizer; minimal odor.
Cons: The fermented material still needs to decompose further (often outside your apartment); requires purchasing Bokashi bran regularly.
What you need:

Airtight Bokashi bucket(s) with a spigot
Bokashi bran
Kitchen scraps (even meat and dairy!)

3. Electric Composter/Food Cycler

These kitchen appliances are the quickest solution, turning food scraps into a dry, soil-like amendment in a matter of hours using heat and aeration. They are very compact and user-friendly.

How it works: You simply toss your food scraps into the appliance, close the lid, and press a button. The machine dries, grinds, and aerates the waste.
Pros: Very fast, eliminates odors, compact, can handle most food scraps, simple to operate.
Cons: High upfront cost, requires electricity, the end product is more like a dried food pulp than true compost and may need further breakdown before being added to plants.
What you need:

An electric composter machine
Food scraps

4. Continuous Flow or Tumbler Composter (Small Scale)

While larger compost bins and tumblers are common for yards, there are smaller versions that can work on a balcony or patio. A continuous flow bin has an opening at the top for adding scraps and another at the bottom for harvesting finished compost. Tumblers are enclosed, rotating drums.

How it works: You add a mix of “greens” (food scraps) and “browns” (carbon-rich materials) to the bin or tumbler. The contents are regularly mixed or tumbled to aerate them.
Pros: Can process larger volumes than worm bins, faster than static piles, can be kept relatively neat.
Cons: Requires outdoor space (balcony, patio), can be heavier to manage, potential for odors if the balance of greens/browns is off.
What you need:

A small compost bin or tumbler
“Greens” (kitchen scraps)
“Browns” (shredded paper, dried leaves, cardboard)
Compost starter or activators (optional)

What Can You Compost in an Apartment?

The list of compostable materials is pretty extensive, but it varies slightly depending on your chosen method. For most apartment methods (especially worm composting), it’s best to stick to plant-based materials.

Good Compostables (Greens – Nitrogen-Rich):

Fruit and vegetable scraps (peels, rinds, cores, leaves)
Coffee grounds and filters
Tea bags (staples removed, natural fiber bags only)
Eggshells (crushed)
Stale bread and crackers (in moderation for worm bins)
Houseplant trimmings

Good Compostables (Browns – Carbon-Rich):

Shredded newspaper (avoid glossy inserts)
Shredded cardboard (uncoated)
Paper towels and napkins (free of grease and chemicals)
Dryer lint (from natural fibers like cotton)
Sawdust (from untreated wood)
Spent coffee filters and tea bags

What to Avoid (Especially for Apartment Composting):

Meat, fish, and bones (attract pests, smell bad)
Dairy products (attract pests, smell bad)
Oily or greasy foods
Diseased plant material
Pet waste (from cats and dogs – can contain pathogens)
Weeds that have gone to seed
Chemically treated yard waste or wood
Glossy or coated paper/cardboard
Synthetic materials

Note on Bokashi and Electric Composters: These methods can often handle meat, dairy, and oily foods, which are typically excluded from vermicomposting or standard composting. Always check your specific appliance or process guidelines.

Setting Up Your Worm Bin: A Step-by-Step Guide

Let’s dive deeper into vermicomposting, as it’s an ideal choice for many apartment dwellers. It’s surprisingly simple and incredibly rewarding!

Step 1: Gather Your Supplies

You’ll need a worm bin, bedding, and your worms. You can purchase a ready-made bin or create your own from opaque plastic storage totes. For DIY, two totes are common: one for the worms to live in, and a second one to catch any liquid (leachate).

Bin preparation: If DIYing, drill small holes in the bottom of the top bin for drainage and aeration, and in the lid for air. Place this bin inside the second, solid bin.
Bedding: Shredded newspaper, corrugated cardboard, partially composted leaves, or coconut coir are excellent choices. Moisten the bedding until it’s damp like a wrung-out sponge.

Step 2: Add Worms and Bedding

Fluff up the damp bedding and fill the working bin about ¾ full. Gently place your red wiggler worms on top of the bedding. Let them move in on their own—don’t bury them! They’ll start burrowing as they get comfortable.

Tip: It’s common for worms to try and escape initially as they adjust to their new environment. Leaving the lid slightly ajar for the first day or so can help them settle.

Step 3: Introduce Food Scraps Smartly

Start small! Don’t overload your new worm population. Bury a small amount of food scraps (about a handful per pound of worms) under the bedding in one corner of the bin. This encourages them to migrate to where the food is.

What to feed them: See the “Good Compostables” list above. Chop or blend larger items like melon rinds to speed up decomposition. Avoid whole citrus fruits unless you have a very established bin, as their acidity can be bothersome. Burying the food helps prevent odors and fruit flies.

Step 4: Maintain Your Worm Bin

Feeding: As the worms process the food, gradually increase the amount you feed them. You can start creating a new feeding area each week, rotating through the bin, so the worms always have fresh scraps to eat while older scraps are being processed.

Moisture: The bedding should always feel like a damp sponge. If it’s too dry, add a little water. If it’s too wet, add more dry bedding material.

Aeration: Gently fluff the bedding every week or two with a garden fork or your hands to ensure good airflow. Avoid disturbing the worms too much.

Harvesting: After 2-4 months, you should have finished worm castings. You can “mine” the bin by creating a large feeding area on one side and letting the worms migrate there, leaving the other side free of worms and ready for harvesting. Alternatively, you can dump the entire contents onto a tarp in sunlight and separate the worms from the compost.

Composting Bin Comparison for Small Spaces

Choosing the right bin is key to successful apartment composting. Here’s a quick look at some popular options:

Composting Method	Best For	Space Needed	Ease of Use	Odor Potential	Cost (Initial)
Worm Bin (Vermicomposting)	Kitchen scraps, plant debris; high-quality compost output	Small (can fit under sink or on a shelf)	Moderate (requires managing worms and food)	Low (when managed properly)	$50 – $150 (DIY can be cheaper)
Bokashi Bin	All food scraps (including meat/dairy); pre-composting	Small (similar to worm bin)	Easy to moderate (requires bran and bucket maintenance)	Very Low (fermented smell, not rot)	$50 – $100
Electric Composter	All food scraps; fast processing	Small countertop appliance	Very Easy (push a button)	Very Low (often has filters)	$300 – $600+
Small Balcony Tumbler/Bin	Larger volumes of kitchen scraps and yard waste	Medium (requires balcony/patio space)	Moderate (requires turning/mixing)	Moderate (if not balanced)	$75 – $200

Troubleshooting Common Apartment Composting Issues

Even with the best tips, you might run into a few snags. Don’t worry, these are common and easily fixed!

Problem: My compost bin smells bad.

Reason: Too wet, too many “greens” (nitrogen-rich materials), or not enough air. For worm bins, this often means the worms are starved for oxygen or are being fed too much.

Solution: For worm bins, add more dry bedding (shredded paper/cardboard) to absorb moisture and introduce air. For other methods, ensure you have a good balance of greens and browns (carbon materials) and that the bin is aerated properly. If using Bokashi, ensure the lid is sealed tightly. For electric composters, there might be an issue with the filter.

Problem: I have fruit flies or other pests.

Reason: Exposed food scraps are a buffet for tiny bugs. In worm bins, this could also indicate the bin is too wet or the wrong types of food are being added.

Solution: Always bury food scraps beneath the bedding in worm bins. Ensure lids are tightly sealed. For outdoor bins, consider adding a layer of finished compost or soil on top of the food scraps. For Bokashi, make sure the lid is sealed. Electric composters are usually pest-proof.

Problem: My worms are dying or trying to escape.

Reason: The environment is likely too acidic, too wet, too hot, or there’s a lack of food. This can happen if too much citrus is added, or the bin is in direct sunlight.

Solution: Check the moisture level and add dry bedding if too wet. Avoid adding large amounts of acidic foods like citrus. Ensure the bin is in a temperature-stable location (typically 55-77°F or 13-25°C). For escaped worms, add more bedding and bury food thoroughly.

Problem: My compost isn’t breaking down.

Reason: It might be too dry, too cold, or lacking nitrogen (greens). Too many browns can also slow things down.

Solution: Increase moisture if dry. Add more “green” materials like fruit and veggie scraps. For tumblers, make sure you’re turning it regularly. For electric composters, ensure it’s plugged in and running correctly.

Genius Tips for Apartment Composting Success

Here are some insider secrets to keep your apartment composting running smoothly:

Chop It Up! Smaller pieces break down much faster, especially for worm bins. Blend or finely chop tougher scraps like melon rinds or carrot tops.
Freeze Your Scraps: Don’t have enough scraps to feed your worms daily? Keep a small container in your freezer for food scraps. This prevents odor and pre-softens items for your worms.
The Coffee Ground Secret: Worms love coffee grounds! They also help absorb odors and provide beneficial microbes.
Eggshells are Power: Crushed eggshells add beneficial calcium and help aerate the compost.
Manage Moisture Like a Pro: Too wet is a common issue. Always aim for the consistency of a wrung-out sponge. Add dry browns to soak up excess moisture.
Be Patient with New Worms: Red wigglers are sensitive to changes. Give them a week or two to settle in before going full steam on feeding them.
Find a “Compost Buddy”: Connect with neighbors or community gardens. They might accept your fermented Bokashi waste or your finished compost if you don’t have immediate use for it. Local composting facilities are also an option. Check out resources through your city or local government for composting drop-off points. The <a href="https://www.epa.gov/recycle/reducing-wasted-
