Composting for Small Apartments Training: Your Genius Guide to Apartment Composting
Hey there! Troy D Harn here, your go-to friend for making home projects, gardening, and well, pretty much anything home-related, feel way less complicated. You know how sometimes a great idea feels too big or too messy to even start? That’s how composting can feel for apartment dwellers. You see all those food scraps and think, “Where would this even go?” But trust me, with a little know-how and the right tools, composting in a small apartment is totally within reach. It’s not about having a giant bin in the backyard; it’s about smart, contained systems that work for you.
We’re going to walk through this together, from picking the right system to what you can and can’t compost. By the end, you’ll have a clear plan to start your own apartment composting journey. It’s easier than you think, and the benefits for your wallet and the planet are huge!
Why Bother Composting in an Apartment?
Let’s get real. Why would you want to bring composting into your living space, especially if it’s on the smaller side? Glad you asked! Here are some compelling reasons:
- Slash Your Trash: Food scraps make up a significant portion of household waste. Composting dramatically reduces what you send to the landfill, which is good for everyone.
- Create Amazing Fertilizer: Your finished compost is like black gold for plants. It’s a nutrient-rich soil amendment that makes gardens (even tiny balcony ones!) thrive.
- Reduce Greenhouse Gases: When food waste breaks down in landfills, it produces methane, a potent greenhouse gas. Composting diverts this waste and avoids harmful emissions.
- Save Money: If you’re a plant lover, you’ll spend less on potting soil and fertilizers. Plus, less trash can sometimes mean lower waste disposal fees.
- Feel Great About It: It’s a tangible way to live more sustainably and contribute to a healthier planet, right from your kitchen.
Choosing Your Apartment Composting System
When we talk about composting in small spaces, we’re not talking about a big, stinky pile. We’re talking about smart, compact, and often odorless solutions. The most popular and effective methods for apartments fall into a few categories. Let’s explore them:
1. Worm Composting (Vermicomposting)
This is probably the most common and highly recommended method for apartment dwellers. It uses special composting worms (usually Red Wigglers, Eisenia fetida) to break down your food scraps. The result is a nutrient-dense material called worm castings, which is fantastic for plants.
- How it Works: Worms eat food scraps and then excrete nutrient-rich castings. You feed them, they do the work!
- Pros:
- Very efficient and produces high-quality compost.
- Relatively odorless when managed correctly.
- Compact systems are readily available.
- Can be done indoors year-round.
- Cons:
- Requires specific types of worms (not earthworms from your garden).
- There’s a slight learning curve to keep the worms happy.
- Can’t handle all types of food scraps (e.g., meat, dairy, oily foods).
2. Bokashi Composting
Bokashi is a different kind of process. It’s technically fermentation, not decomposition, using a special Bokashi bran that contains beneficial microbes. You layer your food scraps with this bran in an airtight bucket. It pickles your waste, breaking down materials that traditional composting might struggle with, like meat and dairy.
- How it Works: Anaerobic (without oxygen) fermentation with added microbes breaks down waste.
- Pros:
- Can handle meat, dairy, oils, and cooked foods.
- Compact, airtight system means no bad odors.
- Fast initial processing.
- Produces a nutrient-rich liquid (Bokashi tea) that can be used as fertilizer.
- Cons:
- The fermented material isn’t finished compost; it needs to be buried or added to a traditional compost bin to fully decompose (you might need to arrange this with a community garden or find a neighbor!).
- Requires purchasing special Bokashi bran.
- The fermented material can have a pickled smell until it’s fully composted.
3. Electric Composter/Food Cycler
These countertop appliances use heat and aeration to break down food scraps into a dry, soil-like material in a matter of hours. They are the quickest option and require minimal effort.
- How it Works: Uses heat, air, and grinding to dehydrate and break down scraps rapidly.
- Pros:
- Extremely fast – usually 3-8 hours.
- Very little effort required.
- Handles most food scraps, including meat and dairy.
- No odors during the process.
- Compact for a countertop.
- Cons:
- Highest upfront cost.
- The end product is more of a dried food pulp than true compost, and may need further processing or mixing with soil to provide maximum benefit.
- Uses electricity.
4. Small Tumbler or Bin Composter
While often thought of for balconies or small yards, some very compact tumbler or bin systems can work in a well-ventilated area or larger balcony. These are more traditional composting methods but scaled down.
- How it Works: Aerobic decomposition (with oxygen) in a contained unit.
- Pros:
- Can process a slightly larger volume than worm bins if space allows.
- Composted material is ready to use.
- Cons:
- Requires more space; often not ideal for very small apartments.
- Can attract pests if not managed carefully.
- May produce odors if not aerated properly.
- Requires turning or mixing.

Getting Started with Worm Composting: Your Step-by-Step Training
For most apartment dwellers, worm composting is the sweet spot. It’s efficient, relatively easy, and produces amazing results. Let’s get you set up!
Step 1: Gather Your Supplies
You don’t need much, but getting the right items is key:
- A Worm Bin: You can buy a pre-made worm bin (often stackable trays) or make your own from opaque plastic storage containers. A bin around 10-20 gallons is a good start. Make sure it has a lid! You can find great DIY guides online from places like the EPA on how to modify containers for ventilation and liquid collection.
- Composting Worms: You need RED WIGGLERS (Eisenia fetida), not earthworms from your garden. Order them online from reputable worm farms. Start with about 1/2 to 1 pound of worms.
- Bedding Material: This is what your worms live in. Good options include shredded newspaper (avoid glossy pages), shredded cardboard, coir (coconut fiber), or a mix of these. You need enough to fill about half the bin. Moisten it until it’s like a wrung-out sponge.
- Worm Food Scraps: Start with small amounts of fruit and vegetable scraps, coffee grounds, tea bags, and crushed eggshells.
- A Small Scraper or Trowel: For burying food scraps and harvesting.
- A Spray Bottle: For misting if the bin gets too dry.
- Optional: A Worm Bin Additive: Some people add a bit of garden soil or finished compost to help introduce beneficial microbes.
Step 2: Set Up Your Worm Bin
- Prepare the Bin: If you’re DIYing, drill small holes (about 1/8 inch) on the sides and bottom for aeration and drainage. You’ll want a way to collect any liquid that drains out (called ‘leachate’ or ‘worm tea’); a tray underneath or a spigot at the bottom of the bin works. If using stackable trays, drill holes only in the bottom of the “working” tray and ensure the collection tray is at the very bottom and watertight.
- Add Bedding: Moisten your shredded newspaper, cardboard, or coir until it’s damp but not dripping. Fluff it up and fill the bin about halfway to two-thirds full.
- Add Worms: Gently place your worms on top of the bedding. Leave the lid off for about 30 minutes to an hour. The worms will burrow down into the bedding to escape the light, which is exactly what you want. This shows they are healthy and ready to settle in.
- Replace Lid: Once the worms have burrowed, put the lid back on. Ensure there’s some ventilation (small holes or a slightly ajar lid).
- Let Them Settle: Leave the worms for a few days to get used to their new home before adding any food. Keep the bedding moist.
Step 3: Feeding Your Worms
This is where the magic happens!
- Start Small: When you’re ready to feed, start with a small amount of scraps. Chop larger scraps into smaller pieces – worms aren’t big on chewing.
- Bury the Food: Dig a small “pocket” in one corner of the bin. Add your food scraps, then cover them completely with bedding material. This prevents odors and fruit flies.
- Alternate Sides: In the future, bury food scraps in a different part of the bin each time. Worms will move to where the food is.
- What to Feed:
- Fruits (no citrus skins in large amounts)
- Vegetables (avoid too much onion or garlic)
- Coffee grounds and paper filters
- Tea bags (remove staples)
- Crushed eggshells (helps with grit and balances pH)
- Small amounts of cooked pasta or rice (unseasoned)
- What to AVOID:
- Meat, fish, bones
- Dairy products (cheese, milk, yogurt)
- Oily or greasy foods
- Spicy foods
- Citrus in large quantities
- Diseased plants
- Pet waste
Step 4: Maintaining Moisture and Aeration
Worms need a damp environment, like a rainforest floor.
- Moisture: The bedding should feel like a wrung-out sponge. If it’s too dry, mist it with water. If it’s too wet, add more dry bedding.
- Aeration: The bedding needs air. Gently fluff the top layer every so often with your trowel. The holes in the bin also help.
Step 5: Harvesting Your Worm Castings and “Worm Tea”
After a few months, your worms will have processed a lot of the bedding and food, leaving behind nutrient-rich worm castings. You’ll also likely collect liquid in the bottom tray.
- Harvesting Castings: There are several methods. A common one is the “migration” method: Stop feeding one side of the bin for a few weeks and add all new food to the other side. Most worms will migrate to the food. You can then scoop out the castings from the original side. Alternatively, you can dump the whole bin onto a tarp, create piles of compost with a few worms on top, and wait for the worms to burrow down, then scoop off the material above them. Sift out any uncomposted material and return it to the bin.
- Using Worm Tea: The liquid collected at the bottom (leachate) is very concentrated. Dilute it with water (about 1 part tea to 10 parts water) and use it to water your plants. If it smells bad, it’s too concentrated and may need to be diluted further or even allowed to sit for a day or two before use.
Tips for Success in Apartment Composting
Here are a few extra pointers to make your composting journey smooth sailing:
- Start Small: Don’t overwhelm your worms (or yourself!) with too many scraps at first.
- Chop It Up: Smaller pieces break down faster and are easier for worms to eat.
- Balance Greens and Browns: While worms are forgiving, a good mix of nitrogen-rich “greens” (food scraps) and carbon-rich “browns” (bedding) is ideal. If your bin seems too wet or smells, you might need more browns.
- Patience is Key: Composting takes time. Don’t get discouraged if it’s not producing finished compost overnight.
- Troubleshoot Odors: Bad smells usually mean the bin is too wet, has too much nitrogen, or isn’t getting enough air. Add dry bedding, bury food scraps well, and ensure good airflow.
- Where to Put Your Bin: Keep it in a location with a relatively stable temperature, out of direct sunlight. Under a sink, in a closet, or on a covered balcony are common spots. Worms don’t like extreme heat or cold.
