Why Compost Food Scraps Indoors?

Composting food scraps inside is good for many reasons. It helps the planet. It cuts down on trash you send to the landfill. Food waste in landfills makes bad gases. Composting stops this. It also makes something great for your plants. This is called compost. It’s like super food for soil. It makes plants grow strong and healthy.

Getting Started: Choosing and Setting Up Your Bin

Starting is simple. You need a bin. Where you put it matters too. Setting up a kitchen compost bin is the first big step.

Picking the Right Bin

There are many types of kitchen compost bins. The best kitchen compost bin types depend on your needs. Do you just want to collect scraps? Or do you want them to break down right in the bin?

• Simple Collection Bins: These are just containers. You put scraps in them. Then you take the full bin outside to a bigger compost pile or a special pick-up.

  • Looks: Often small buckets. They might be plastic, ceramic, or metal.
  • Size: Small enough to sit on a counter. Or big enough to go under the sink.
  • Lids: Many have lids to keep smells in. Some have filters in the lid.
  • Good for: People who have an outdoor compost pile. Or those who want a simple start. They don’t actually make compost inside. They just hold scraps for a short time.

• Bins That Break Down Scraps Inside: These bins actually start or finish the composting process in your kitchen. This is part of indoor composting methods.

  • Bokashi Bins: These use a special bran mix. The bran has tiny living things on it. You layer scraps and bran. Close the lid tightly. It’s not true composting. It’s fermentation. It pickles the scraps.
    • What you get: Pickled scraps. These need to be buried outside or added to a regular compost pile to finish.
    • Smell: Can smell like vinegar or pickles. Not like rotten food if done right.
    • Good for: People who make a lot of scraps. It handles meat and dairy better than other methods.
  • Worm Bins (Vermicomposting): These use special worms. The worms eat the scraps. Their waste is great compost called castings. Vermicomposting in kitchen is a popular way to compost indoors.
    • Looks: Often plastic bins with trays. Worms live in the bins.
    • What you get: Worm castings. These are rich, dark, soil-like.
    • Smell: Should smell like earth. Bad smells mean something is wrong.
    • Good for: People who like a little project. It’s fun to watch the worms. Needs care to keep the worms happy.

Think about how much space you have. Think about how many scraps your house makes. This helps you pick the right bin.

Picking a Spot for Your Bin

Where you put your bin is important.

• Countertop: Simple collection bins are often put here. Easy to reach while cooking. Make sure it’s not too big.
• Under the Sink: A common spot for collection bins. Hides the bin away. Good for bins that might not look pretty.
• Pantry or Laundry Room: If you have space. Good for larger bins or worm bins. These spots are often a steady temperature. Worms like steady temps.
• Balcony or Patio (if attached to kitchen): If you have a small outdoor space right by the kitchen door. Some bins can go here.

Choose a spot that is easy to use. But also a bit out of the way. This helps keep it clean and reduces smells from spreading.

What Goes in Your Kitchen Compost Bin?

Knowing what to put in kitchen compost bin is key. It’s not everything! Compost needs a mix of ‘green’ things and ‘brown’ things.

• Green things: These are fresh, wet materials. They have lots of nitrogen. Think kitchen scraps!

  • Fruit peels and cores
  • Vegetable scraps (like potato skins, carrot tops, outer leaves)
  • Coffee grounds (and paper filters)
  • Tea bags (check they are compostable, many are)
  • Egg shells (crush them)
  • Old bread and grains (in moderation)
  • Small amounts of plant trimmings or wilted flowers (from houseplants)

• Brown things: These are dry materials. They have lots of carbon. They help keep the compost from getting too wet and smelling bad.

  • Dry leaves (if you have some handy)
  • Shredded newspaper (black and white sections are best)
  • Shredded plain cardboard (like from cereal boxes, no glossy print or tape)
  • Paper bags (torn up)
  • Paper towel rolls (torn up)
  • Sawdust (from plain wood, not treated)
  • Paper napkins (as long as they are not greasy)

What NOT to Put In Your Kitchen Compost Bin (Usually)

Some things should not go in most kitchen compost bins. They can cause smells, attract pests, or not break down well indoors.

• Meat or fish scraps
• Bones
• Dairy products (milk, cheese, yogurt, butter)
• Oily or greasy foods (like cooking oil, greasy pizza boxes)
• Pet waste (dog or cat poop)
• Diseased plants
• Chemically treated wood or sawdust
• Glossy paper or magazines
• Plastic, metal, or glass (obviously!)
• Any materials that say they are “biodegradable” but are not certified compostable.

Note: Bokashi bins can handle meat and dairy. But the pickled scraps still need to go to a regular compost pile or be buried to finish. Worm bins usually cannot handle meat, dairy, oils, or greasy foods. Worms are picky eaters!

Mixing green and brown things is important. Too many greens make it wet and smelly. Too many browns make it dry and slow. Aim for a good mix. Maybe two parts green to one part brown by volume. If you add a lot of wet scraps, add some shredded paper or cardboard too.

How to Use Your Kitchen Compost Bin Day-to-Day

Using your bin is part of composting food waste indoors. It’s usually simple.

1. Open the Lid: Lift the lid when you have scraps.
2. Add Scraps: Put in the approved food bits. Try to break up bigger pieces. Smaller pieces break down faster.
3. Add Brown Stuff (Optional but Good): If you just added a lot of wet green stuff, tear up some newspaper or cardboard and add it. This helps soak up wetness and adds carbon.
4. Close the Lid: This is very important! A good lid keeps smells in. It also helps keep pests out.

For worm bins or other active bins, you might also:

• Bury Scraps (Worms): Lift some bedding (like shredded paper and coconut coir). Put the scraps underneath. Cover them up. This helps prevent smells and pests. Don’t add too much food at once. Worms can only eat so much.
• Add Bokashi Bran (Bokashi): Layer scraps with a sprinkle of bokashi bran. Press the scraps down to remove air. Close the lid tightly.

Keeping Your Bin Fresh: Preventing Smells and Pests

Nobody wants a smelly kitchen! Preventing kitchen compost bin smell is a top goal. Good news: a well-managed bin should not smell bad. If it smells rotten, something is wrong.

Stopping Bad Smells

• Keep the Lid Closed: A tight lid is your best friend.
• Empty Often: If you’re just using a collection bin, empty it outside every few days. Don’t let scraps sit and rot for too long.
• Add Brown Stuff: This is key! If your bin is wet and stinky, add more shredded paper, cardboard, or dry leaves. Mix it in a little if you can. Brown stuff soaks up liquids and balances the greens.
• Keep Out Bad Stuff: Meat, dairy, oils, and greasy food are big smell makers. Don’t put them in.
• Rinse When Empty: If you use a collection bin, rinse it out with water and a little soap each time you empty it. Let it dry before using again.
• Use Filters: Some bins have carbon filters in the lid. These help catch smells. Change them when they stop working (check the bin’s guide).
• Bury Scraps in Worm Bins: Putting food under the bedding helps keep smells away.

Dealing with Pests (Mostly Fruit Flies)

Fruit flies are small flying insects. They love ripening fruit and wet, exposed food scraps.

• Keep the Lid Closed: Again, a tight lid is the main defense.
• Bury Scraps (Worm Bins): This hides the food source from flies.
• Add a Layer of Brown Stuff: A layer of shredded paper or a handful of dry leaves on top of the scraps can make it harder for flies to get to the food.
• Don’t Add Too Much Food (Worm Bins): If worms can’t eat it fast enough, it sits there and can attract flies.
• Check Moisture: Fruit flies like wet places. Make sure your bin isn’t too soggy. Add more brown stuff if it is.
• Fruit Fly Trap (Outside the Bin): If you see flies, you can make a simple trap. Put apple cider vinegar and a drop of dish soap in a small dish. Cover it tightly with plastic wrap. Poke small holes in the top. Flies go in but can’t get out. Put this near the bin, not in it.

Maintaining Your Indoor Compost Bin

Maintaining indoor compost bin keeps it working well. How you care for it depends on the type of bin.

For Simple Collection Bins:

• Empty Regularly: Don’t wait until it’s overflowing or very smelly.
• Rinse: Clean it when you empty it.
• Replace Filters: If it has a lid filter, change it as needed.

For Active Bins (Bokashi, Worms):

These need more care because the composting (or fermenting) is happening inside.

• Bokashi Bins:

  • Keep it Airtight: The lid must be closed tightly after each use. This is key for fermentation.
  • Drain “Compost Tea”: Bokashi bins often have a spigot at the bottom. Liquid will collect here. This is sometimes called “compost tea” but it’s really fermentation liquid. It’s strong. Drain it often (every few days). You can use it watered down (1 part liquid to 100 parts water) for plants. Or pour it down drains (it can help clean them).
  • Add More Bran: Make sure you add enough bran with each layer of scraps. Follow the bran’s directions.
  • Bury Pickled Scraps: Once a bin is full and has sat for a couple of weeks (to finish fermenting), you need to mix the contents into soil or an outdoor compost pile to let them fully break down.

• Worm Bins (Vermicomposting in Kitchen):

  • Feed Them Right: Only give worms approved food scraps. Don’t overfeed. Add small amounts often, rather than a lot all at once.
  • Keep Moisture Right: The bedding should be like a wrung-out sponge. Not dry, not dripping wet. If too dry, add a little water. If too wet, add more dry brown bedding (shredded paper, cardboard).
  • Keep Air Flowing: Worms need air. Don’t pack the bin down. You can gently stir the top layer sometimes, being careful not to hurt the worms. Adding lots of fluffy brown material helps keep it airy.
  • Keep Temperature Steady: Worms like temperatures between 50°F and 80°F (10°C to 27°C). Room temperature is usually fine. Don’t let the bin get too hot or too cold.
  • Harvest Castings: Over time, the bin will fill with dark worm castings. You’ll need to take these out to use them and add new bedding. This can be done every few months. There are different ways to do this (like moving food to one side, or using light to separate worms from castings).

Table: Quick Maintenance Checks

Bin Type	Check For	Action If Needed
Collection Bin	Fullness	Empty outside
	Smells	Empty, rinse, add brown stuff, check lid
Bokashi Bin	Lid Seal	Ensure it’s tight
	Liquid (Tea)	Drain regularly
	Smells	Add more bran, check seal
	Fullness	Let sit for 2 weeks, then bury/add out
Worm Bin	Food Level	Add small amounts often, not too much
	Moisture	Like sponge? Add water or dry paper
	Smell	Usually too wet or too much food; add brown
	Worm Health	Are they active? Are scraps breaking down?
	Castings Level	Harvest every few months

What Happens After the Kitchen Bin?

What you do next depends on your bin type and what you want to achieve.

• Simple Collection Bins: The scraps from these bins are just the first step. You take them to:

  • An outdoor compost pile or bin.
  • A municipal composting program (like a green bin pick-up).
  • A local community garden compost drop-off.
    The actual composting happens after they leave your kitchen bin.
    

• Bokashi Bins: The fermented scraps are not finished compost. They are acidic and need more time to break down fully. You should:

  • Bury them in your garden. They will break down quickly underground.
  • Add them to an outdoor compost pile.
  • Let them finish in a special bin outside for a few more weeks.

• Worm Bins: The material in a healthy worm bin is compost (worm castings).

  • You can use the castings directly in your potted plants or garden.
  • Harvest the castings when the bin is full or looks mostly like dark soil.

Top Tips for Beginners

Starting kitchen composting can feel like a lot. But it’s simple if you take it step-by-step. Here are some beginner kitchen composting tips:

• Start Simple: Use a basic collection bin first. Get used to putting scraps in it and emptying it.
• Keep it Small: Don’t get a huge bin at first. A small one is easy to manage.
• Empty Often: This is the best way to avoid smells with a simple collection bin.
• Balance Greens and Browns: If you add wet scraps, follow with some torn paper. This is one of the most helpful beginner kitchen composting tips.
• Don’t Compost the “Forbidden” Items: Stick to fruits, veggies, coffee, tea, and egg shells at first. Avoid meat, dairy, and oils.
• Read Your Bin’s Guide: If you buy a special bin (like Bokashi or worm bin), read the book or guide that came with it. It has steps for that specific bin.
• Be Patient: Composting takes time. Worms eat at their own speed. Fermentation follows its own path.

Why It’s Worth It

Using a compost bin in your kitchen is a great habit. It feels good to use your food waste for something good. You help the planet. You make valuable food for plants. It’s a simple act with big effects.

Frequently Asked Questions (FAQ)

Here are answers to common questions about kitchen composting.

Q: How often do I need to empty my kitchen compost bin?

A: For simple collection bins, empty it every 2-4 days. Or when it’s full. Or if you start to notice smells. The more often you empty it, the less chance of bad smells or fruit flies. For Bokashi or worm bins, you don’t empty them daily. You add material until they are full, then manage them as described (ferment Bokashi, harvest worm castings).

Q: What if I get fruit flies?

A: First, check your lid. Make sure it’s closed tightly. Then, add a layer of dry brown material (like shredded newspaper) on top of the scraps. For worm bins, make sure scraps are buried and you aren’t adding too much food. You can also make a simple fruit fly trap with vinegar and soap near the bin.

Q: Will a kitchen compost bin attract pests like mice or ants?

A: A well-managed indoor bin usually does not attract these pests. Make sure your lid is tight. Do not put meat, dairy, or oily foods in standard bins (these are big attractants). If you’re using a worm bin, make sure the bin is sealed and you are not overfeeding. If you do get pests, you may need to stop adding scraps, deal with the pests, and perhaps empty the bin outside to restart.

Q: Can I use any worms for worm composting?

A: No. You need specific composting worms, usually Red Wigglers (Eisenia fetida) or European Nightcrawlers (Eisenia hortensis). Garden earthworms are not good for indoor bins. They need different conditions and burrow deep, which isn’t suited for a bin environment. You can buy composting worms online or from a local worm farm.

Q: My bin smells rotten, what’s wrong?

A: A rotten smell usually means it’s too wet and not getting enough air. Or you put something in you shouldn’t have (like meat or dairy in a standard bin). For collection bins, empty and wash. For active bins, try adding more dry brown material (shredded paper, cardboard). Gently stir the top layer to add air (don’t do this too much in worm bins). Check that you are only adding approved items.

Starting kitchen composting is a simple step towards less waste and healthier plants. Choose your bin, know what to put in, and learn simple care steps. You can do it!
