Composting for Small Apartments Training: Your Genius Guide to Apartment Composting

Hey there, apartment dwellers! Troy D Harn here, your go-to friend for making home and garden projects totally doable, no matter how small your space. Today, we’re tackling something awesome: composting for small apartments. Think you need a sprawling garden and a giant bin to compost? Nope! We’re going to break down how you can easily compost right in your kitchen, turning your food scraps into valuable soil amendments. It’s easier than you think, and it’s a super rewarding way to be more eco-friendly.

Composting is basically nature’s way of recycling. By breaking down organic waste, you create a nutrient-rich material called compost, or “black gold,” which is fantastic for plants. For apartment folks, this might seem like an impossible dream, but I promise, it’s not. We’ll explore the best methods, the tools you’ll need, and how to keep it all clean and odorless. Ready to become an apartment composting ninja?

Why Compost in a Small Apartment?

You might be thinking, “Why bother composting when I have so little space?” Great question! Let’s break down the perks:

• Reduces Landfill Waste: A huge chunk of what we throw away is food scraps and yard waste. Composting diverts this from landfills, which helps reduce methane gas (a potent greenhouse gas) and saves valuable landfill space.
• Creates Nutrient-Rich Fertilizer: Finished compost is like a superfood for your plants. It improves soil structure, helps retain moisture, and provides essential nutrients, making your houseplants, balcony garden, or community garden plots thrive.
• Saves Money: You’ll buy less soil and fertilizer for your plants, and you’ll notice fewer items ending up in your trash can, potentially lowering waste disposal fees in some areas.
• Educational and Rewarding: It’s a fantastic way to learn about natural processes, close the loop on your food consumption, and feel good about making a positive impact.
• Odorless (Yes, Really!): When done correctly, composting doesn’t smell bad. In fact, it should have a pleasant, earthy smell. We’ll cover how to ensure this!

Choosing Your Apartment Composting Method

The biggest hurdle for apartment composting is space and managing potential odors or pests. Luckily, there are a few fantastic methods designed specifically for small spaces. We’ll dive into the most popular ones:

1. Worm Composting (Vermicomposting)

This is perhaps the most popular and efficient method for apartment dwellers. Worm bins use specific types of worms (red wigglers, not your garden-variety earthworms) to break down food scraps into nutrient-rich castings.

How it Works:

You create a habitat for the worms with bedding material (like shredded newspaper or coco coir). Then, you feed them your kitchen scraps. The worms eat the scraps and their waste becomes compost. It’s a self-contained system that’s surprisingly tidy when managed correctly.

Pros:

• Fast processing of food scraps.
• Produces high-quality compost (worm castings).
• Minimal odor if managed properly.
• Compact and can fit under a sink or in a closet.
• Relatively inexpensive to set up.

Cons:

• Requires specific types of worms, which need to be purchased.
• Can be sensitive to temperature extremes.
• Some people have a “ick” factor about worms.
• Requires a bit of attention to feeding and moisture levels.

What You’ll Need:

• Worm Bin: You can buy purpose-made stackable bins or create your own from opaque plastic storage totes. Look for bins with ventilation and drainage. A common DIY is two stacking totes: one for collection and one with holes for the worms and bedding.
• Bedding: Shredded newspaper (black ink only), shredded cardboard, coconut coir, or peat moss. This makes up the worm’s home and helps manage moisture.
• Red Wiggler Worms: You’ll need about 1-2 pounds to start. They are different from earthworms and are excellent eaters! You can buy them online from reputable worm farms.
• Food Scraps: Your kitchen waste!
• A Designated Spot: A dark, cool place like under the sink, in a closet, or on a balcony (if temperatures are moderate).

Setting Up Your Worm Bin (Step-by-Step):

1. Prepare the Bedding: Moisten your chosen bedding material so it’s damp like a wrung-out sponge. It shouldn’t be dripping wet. Fluff it up and fill your worm bin about 2/3 full.
2. Introduce the Worms: Gently place your ordered red wigglers on top of the bedding. They will burrow down to escape the light. Leave the lid off for an hour or two to let them settle in.
3. First Feeding: After a day or two, you can start feeding your worms. Bury a small amount of food scraps (about one cup for a pound of worms) under the bedding in one corner of the bin. Avoid overfeeding initially.
4. Regular Feeding: Feed your worms 1-3 times a week, depending on how quickly they are processing food. Always bury the food scraps under the bedding to avoid odors and fruit flies. Rotate feeding spots.
5. Harvesting Castings: After 2-4 months, you’ll start seeing dark, moist bits of compost. To harvest, you can either migrate the worms to one side by adding fresh bedding and food to the opposite side, or dump the bin contents onto a tarp and separate the worms.

2. Bokashi Composting

Bokashi is an anaerobic (without oxygen) fermentation process that pickles your food waste rather than decomposing it. It’s fantastic for handling virtually all food scraps, including meat and dairy, which are typically avoided in traditional composting.

How it Works:

Food scraps are layered in an airtight Bokashi bucket with an inoculant (usually a bran-based mixture with effective microorganisms). The microorganisms break down the waste through fermentation. The end product is a nutrient-rich liquid (Bokashi tea) and fermented solids that need to be buried or added to a traditional compost pile to finish decomposing.

Pros:

• Handles ALL food scraps, including meat, dairy, and oily foods.
• Compact system, fitting easily in a kitchen.
• No unpleasant odors during the pre-composting phase – it smells slightly sweet or pickly!
• Produces a nutrient-rich liquid (Bokashi tea) that can be used as fertilizer after diluting.
• Can be faster than traditional composting.

Cons:

• Requires special Bokashi bran/inoculant.
• The fermented solids are acidic and need further decomposition, typically by burying them in soil or adding them to a regular compost bin. This is the main challenge for apartment dwellers without access to garden space.
• Requires an airtight bucket system.

What You’ll Need:

• Bokashi Bin: An airtight bucket with a spigot to drain the liquid. You can buy these or make your own from two stackable buckets.
• Bokashi Bran/Inoculant: This is a mixture of bran or sawdust infused with beneficial microbes. It’s readily available online.
• Kitchen Scraps: Anything and everything!
• Access to a place to bury the fermented solids: This is crucial. If you don’t have any outdoor space, you might need to partner with a friend with a garden, a community garden, or investigate local composting drop-off sites.

Setting Up Your Bokashi Bin (Step-by-Step):

1. Layer Scraps: Add your food scraps to the Bokashi bin. Chop larger items into smaller pieces for faster fermentation.
2. Add Bokashi Bran: Sprinkle a tablespoon or two of Bokashi bran over the food scraps. Ensure the scraps are well-covered.
3. Press Down: Lightly press the scraps to remove air pockets.
4. Seal and Repeat: Add more scraps, bran, and press down until the bin is full. Each time you add food scraps, sprinkle bran and press.
5. Airtight Seal: Ensure the lid is sealed tightly each time to maintain anaerobic conditions.
6. Drain the “Tea”: The liquid (Bokashi tea) will collect at the bottom. Drain it every 2-3 days using the spigot. Dilute this liquid with water (1:100 ratio) to use as a potent plant fertilizer.
7. Fermentation Period: Once the bin is full, let it ferment for about 2 weeks with the lid sealed.
8. Bury or Add to Compost: After fermentation, the solids are pickled. If you have access to soil, dig a hole about a foot deep and bury the contents. Alternatively, add them to a traditional outdoor compost pile, where they will further decompose within a few weeks.

3. Electric Composters (Food Cyclers)

These are modern marvels that use heat and aeration to break down food scraps into a dry, soil-like amendment in a matter of hours. They are the quickest and often the most user-friendly, but also the most expensive option.

How it Works:

You put your food scraps into a countertop appliance. It tumbles and heats the scraps, significantly reducing their volume and moisture content. The end product is a dry, ready-to-use material that resembles coarse soil.

Pros:

• Extremely fast (hours, not weeks or months).
• Handles most food scraps, often including bones and dairy.
• Very compact and countertop-friendly.
• Virtually odorless during operation.
• Easy to use – just add scraps and press a button.
• Significantly reduces food waste volume.

Cons:

• High upfront cost compared to other methods.
• Requires electricity to run.
• The end product is not technically “compost” in the biological decomposition sense but rather a dehydrated, nutrient-rich material that’s great for soil amendment. It needs to be mixed with soil or existing compost to provide the full benefits of microbial activity.
• Can be noisy, depending on the model.

What You’ll Need:

• Electric Composter Unit: Various brands are available (e.g., Lomi, FoodCycler).
• Kitchen Scraps: Most models accept a wide range.
• Power Outlet: To plug it in.

Using an Electric Composter (Step-by-Step):

1. Load Scraps: Open the appliance and add your food scraps. Follow the manufacturer’s guidelines on what can be included.
2. Close the Lid: Ensure the lid is securely fastened.
3. Select Cycle: Choose the appropriate cycle (often there are different options for different types of food).
4. Start the Machine: Press the start button. The appliance will run for a set period, usually a few hours.
5. Remove Processed Material: Once the cycle is complete, open the unit and remove the dried, reduced food material.
6. Use or Store: You can often mix this directly into your potted plants’ soil or outdoor garden soil. If storing, keep it in a dry container.

What Can You Compost? (And What to Avoid)

Knowing what to feed your composting system is key to success and avoiding unwanted smells or pests. Here’s a general guide, with specific notes for each method.

Compostable Materials (The “Greens” and “Browns”)

Think of compostable materials in two categories:

• Greens (Nitrogen-rich): These are typically moist materials that provide nitrogen, which is essential for the microorganisms that break down waste.
• Fruit and vegetable scraps
• Coffee grounds and tea bags (paper ones)
• Eggshells (crushed)
• Grass clippings (in moderation)
• Fresh plant trimmings
• Browns (Carbon-rich): These are drier materials that provide carbon, essential for energy and structure. They also help keep your compost pile from getting too soggy and smelly.
• Shredded newspaper (non-glossy, black & white ink)
• Shredded cardboard (uncoated)
• Paper towels and napkins (if not greasy or soiled with chemicals)
• Brown paper bags
• Dry leaves
• Sawdust from untreated wood

Materials to Avoid (Generally)

These can attract pests, create odors, or contain pathogens that aren’t ideal, especially in small-space systems:

• Meat and bones (unless using Bokashi or some electric composters)
• Dairy products (unless using Bokashi or some electric composters)
• Oils and greases (unless using Bokashi or some electric composters)
• Diseased plants
• Weeds that have gone to seed
• Pet waste (from cats and dogs – can contain pathogens)
• Treated wood products
• Glossy paper or colored inks
• Synthetic materials
• Ashes from coal

Method-Specific Considerations

Worm Bin: Avoid citrus in large quantities, onions, garlic, spicy peppers, and anything fermented or spoiled. These can harm the worms. Introduce new foods gradually.

Bokashi: Handles almost everything, making it very versatile for apartment kitchens. The key is the subsequent burial or composting of the fermented material.

Electric Composter: Check your model’s manual. Most are very forgiving, but some may have limitations on pit bones or very large avocado pits.

Troubleshooting Common Apartment Composting Problems

Even with the best intentions, you might run into a hitch. Here are some common issues and how to fix them:

Problem: Unpleasant Odors

This is the number one fear for apartment composters. Fortunately, it’s usually easy to fix.

• Cause: Too much “green” material (food scraps) or too much moisture. This leads to anaerobic decomposition, which smells sulfuric or like rotten eggs.
• Solution (Worm Bin): Add more “brown” bedding material (shredded newspaper, cardboard). Ensure good airflow. Bury food scraps completely under the bedding. Check for overfeeding.
• Solution (Bokashi): Ensure the lid is airtight. Add slightly more Bokashi bran. If you have liquid, drain it. The acidic fermentation shouldn’t smell bad, but anaerobic pockets can.
• Solution (Electric Composter): Usually not an issue with these machines, but ensure the filter (if it has one) is clean and the lid is sealing properly.

Problem: Fruit Flies or Other Pests

Annoying, but usually preventable.

• Cause: Food scraps exposed to the air.
• Solution (Worm Bin): Always bury food scraps completely under the bedding. Avoid leaving food scraps sitting on top. If you have an infestation, you can sprinkle a thin layer of diatomaceous earth or food-grade sand on top of the bedding.
• Solution (Bokashi): Very rare as the system is sealed and the fermentation process discourages pests.
• Solution (Electric Composter): Not an issue as it’s a sealed appliance.

Problem: Dryness or Wetness in Worm Bin

Moisture is key for worms.

• Cause: Too little or too much water in the bedding and food.
• Solution for Dryness: Add a bit more water to the bedding, spritz with a spray bottle, or add moist food scraps (like melon rinds).
• Solution for Wetness: Add more dry “brown” bedding material. Ensure the bin has drainage and it’s functioning properly. Gently turn the bedding to aerate it.
