What if there was a super simple way to turn those leftovers into garden gold, right inside your home?
Stick around, because we’re diving into the world of indoor composting. We’ll break down how it works, the different types you can use, and why it might just be the genius, effortless solution you’ve been looking for. You’ll be composting like a pro in no time!
Indoor Composting Review: Genius Effortless Results
Hey neighbors! Troy D Harn here from TopChooser, and today we’re tackling something a lot of us grapple with: what to do with all those kitchen scraps. We’re talking coffee grounds, veggie peels, eggshells – you name it. Traditional composting is great if you’ve got space, but for apartment dwellers or folks with tiny yards, it can seem out of reach. That’s where indoor composting swoops in to save the day!
Think of indoor composting as a super-powered way to recycle your organic waste without the smell, the mess, or the need for a sprawling garden. It’s about bringing the magic of decomposition indoors, making it accessible and frankly, pretty cool. We’re going to explore the different ways you can do this, weigh the pros and cons, and help you find the perfect fit for your home. Ready to turn trash into treasure? Let’s get started!
Why Go Indoor With Your Composting?
Let’s be honest, tossing food scraps in the trash feels like a missed opportunity. They end up in landfills, releasing harmful methane gas. But beyond the environmental nudge, there are some really practical perks to composting indoors:
- Reduces Waste: You’ll be amazed at how much less trash you generate.
- Creates Garden Gold: That finished compost is black, nutrient-rich soil—perfect for your houseplants or garden.
- Saves Money: No need to buy expensive potting soil!
- Accessible for Everyone: No yard? No problem!
- Educational Fun: Great for teaching kids about recycling and nature.
Types of Indoor Composting: Finding Your Perfect Match
When we talk about indoor composting, a few main methods usually come up. Each has its own charm and works best for different lifestyles and kitchens. Let’s take a look:
1. Vermicomposting (Worm Composting)
This is perhaps the most popular and talked-about method for indoor composting. It uses special worms (red wigglers, not your average garden earthworms!) to munch their way through your food scraps. It sounds a bit quirky, but it’s incredibly efficient and produces a fantastic compost called “worm castings.”
How it Works: You’ll need a worm bin – these can be purchased or DIY – filled with bedding material like shredded newspaper or coconut coir. You then introduce your red wigglers and start feeding them your kitchen scraps. The worms eat the scraps and their waste, which is rich in nutrients, is your compost.
What You Can Compost:
- Fruit and vegetable scraps
- Coffee grounds and tea bags (paper filters are okay too)
- Crushed eggshells
- Plain pasta and rice
- Shredded newspaper and cardboard
What to Avoid:
- Meats, bones, and dairy products (can attract pests and smell)
- Oily or greasy foods
- Spicy foods
- Citrus in large quantities (can harm the worms)
- Diseased plants
Pros:
- Produces very nutrient-rich compost (worm castings).
- Relatively odorless if managed correctly.
- Worms process waste quickly.
- Compact systems fit easily in small spaces.
Cons:
- Requires live creatures, which some people might not be comfortable with.
- Need to manage temperature and moisture for the worms.
- Can’t process large amounts of food waste at once.
2. Bokashi Composting
Bokashi is a bit different. It’s a fermentation process that pickles your food waste rather than breaking it down directly. You use a special Bokashi bran, which is inoculated with Effective Microorganisms (EM). These microbes work in an oxygen-free environment to break down the waste.
How it Works: You’ll need a special Bokashi bin with a spigot and airtight lid. You layer your food scraps with the Bokashi bran in the bin, pressing down to remove air. Once full, you seal the bin and let it ferment for about two weeks. After fermentation, the pickled waste needs to be buried in soil (in a garden, planter, or even a large outdoor pot) or added to a traditional compost pile to finish decomposing.
What You Can Compost:
- Almost all food scraps, including meat, dairy, and oils.
- Cooked foods.
- Coffee grounds and tea bags.
- Citrus.
What to Avoid:
- Large bones (though smaller ones can be chopped up).
- Non-food items.
Pros:
- Can handle almost all food waste, including meat and dairy.
- Quick initial processing time (fermentation).
- Produces a liquid “tea” that can be used as fertilizer (diluted!).
- No unpleasant odors if the bin is sealed properly.
- Compact system.
Cons:
- Requires purchasing Bokashi bran.
- The fermented material is acidic and needs to “finish” decomposing in soil, so it’s not a standalone indoor solution for readily usable compost.
- The “tea” needs to be drained regularly.
3. Electric Composting Machines (Food Cyclers)
These are the high-tech wizards of indoor composting. An electric composter is essentially a countertop appliance that dries and grinds your food scraps, significantly reducing their volume and creating a nutrient-rich, soil-like amendment in a matter of hours.
How it Works: You toss your food scraps into the machine, close the lid, and press a button. The machine heats, dries, and grinds the waste in an accelerated cycle, typically 4-8 hours. The end product is powdery and can be mixed directly into soil or added to your garden.
What You Can Compost:
- Most food scraps, including meat, dairy, and bones (check your model’s specifics!).
- Coffee grounds, tea bags.
- Certain biodegradable plastics (verify manufacturer claims).
What to Avoid:
- Large, hard bones (unless specified by the manufacturer).
- Large amounts of liquid.
- Non-food items.
Pros:
- Extremely fast results (hours, not weeks or months).
- Reduces food waste volume dramatically (up to 90%).
- Odorless operation.
- Very easy to use.
- Handles a wide variety of food scraps.
Cons:
- High upfront cost.
- Requires electricity to run.
- The end product isn’t “true” compost in the traditional sense; it’s more of a dried amendment that needs soil microbes to fully break down.
- Can be noisy during operation.
4. Countertop Compost Bins (for collection only)
These aren’t technically “composting” systems in themselves, but they are essential for making any indoor composting method easier. These are small bins you keep on your counter to collect scraps throughout the day, which you then empty into your main composting system (worm bin, Bokashi, or outdoor pile) periodically.
Some come with filters to reduce odors. They’re all about convenience for the initial collection phase.
Pros:
- Keeps your kitchen tidy.
- Reduces trips to your main compost system.
- Many options available, from simple buckets to stylish containers.
Cons:
- Needs to be emptied regularly to avoid smells and pests.
- Doesn’t process waste itself.

Getting Started: Quick Tips for Success
No matter which method you choose, a few universal tips will set you up for success. Think of these as your friendly neighborhood advice for indoor composting!
For Vermicomposting:
- Start Small: Don’t overwhelm your new worm friends with too much food at once.
- Moisture is Key: The bedding should feel like a wrung-out sponge. Too wet, and it can get stinky; too dry, and the worms suffer.
- Chop it Up: Smaller pieces of food scraps break down faster.
- Know Your Worms: Stick to red wigglers (Eisenia fetida). They are the best composters for bins.
- Patience: It takes a little time for worms to acclimate and for the system to balance.
For Bokashi Composting:
- Airtight is Right: Ensure the lid is sealed tightly after each addition to keep oxygen out.
- Flushing the System: Drain off the “Bokashi tea” (liquid byproduct) every few days. Dilute it 1:100 with water for a potent plant fertilizer or pour it down your drains to help clean them!
- Bury it Properly: Once fermented, bury the solids about 6-8 inches deep in soil. This is crucial for the final decomposition stage. A large pot with soil works if you don’t have a yard.

For Electric Composters:
- Read the Manual: Every machine is slightly different. Get to know yours!
- Don’t Overfill: Stick to the recommended fill lines.
- Clean It Out: Wipe down the inside after each cycle and give it a good clean periodically.
- Manage Moisture: Avoid adding very wet items if your machine struggles with them.
Troubleshooting Common Indoor Composting Woes
Even with the best intentions, sometimes things don’t go perfectly. Here are a few bumps in the road and how to smooth them out:
1. Smells Bad!
This is the most common fear! Why it happens and how to fix it:
- Vermicomposting: Usually too much food, too wet, or wrong food added (meat/dairy). Solution: Stop feeding, add dry bedding, bury food scraps deeper, and ensure good aeration.
- Bokashi: Usually a leaky lid allowing air in, or not draining the liquid. Solution: Ensure the lid seals tightly. Drain the liquid regularly. If it smells truly rotten, the batch might be compromised.
- Electric Composters: Generally not an issue, but ensure filters are clean and the unit isn’t left dirty.
2. Fruit Flies or Pests
These tiny invaders can be annoying. What to do:
- Vermicomposting/Bokashi: Keep food scraps buried under the bedding/bran. For flies, you can trap them with a bit of fruit juice in a container with holes. Avoid meat and dairy.
- Countertop Bins: Ensure the lid is secure and the bin is emptied frequently. Filtered bins are best.
For more pest management tips, the University of Minnesota Extension offers great advice on controlling flies and other pests.
3. System Isn’t Working Fast Enough
This is often a patience issue or a sign of imbalance.
- Vermicomposting: Worms need time to adjust. Ensure proper temperature, moisture, and aeration. Don’t overfeed.
- Bokashi: Fermentation is usually reliable if sealed. If the finished product in soil isn’t breaking down, the soil might be too cold, too wet, or lacking microbes.
- Electric Composters: If it’s not drying/grinding, check the power, ensure it’s not overloaded, and that no large hard items are jamming it.
4. Worried About the “Right” Stuff to Compost
It’s natural to be cautious!
- When in doubt, leave it out! Especially with worms, it’s better to be safe.
- Electric composters are the most forgiving for a wide range of materials, but always check your specific model.
- Bokashi is the champion for handling almost everything.
Making the Most of Your Finished Compost
Once your composting journey yields results – be it worm castings, fermented Bokashi matter ready for burial, or the dried output from an electric composter – it’s time for the reward! This nutrient-rich material is a game-changer for your plants.
- For Houseplants: Mix a small amount of compost or castings into your potting soil. It’s like a superfood boost for your indoor green friends.
- For Container Gardens: Similar to houseplants, incorporate compost to enrich the soil in pots and planters.
- For In-Ground Gardens: If you have a small garden bed or balcony planters, you can dig in a generous amount of finished compost to improve soil structure and fertility.
- Bokashi Finishing: Remember, Bokashi requires its fermented material to be buried in soil to complete decomposition. Mix it well with soil in a large pot or garden bed. The microbes in the soil will finish the job.
