In this article, you will learn everything you need to know about composting at home: methods, types of composters, how to avoid problems and what are the real benefits of urban composting.

Why compost at home?

Composting is not just a “green” activity, but an active form of sustainability. Here are a few reasons why it’s worth trying:

✅ You significantly reduce the volume of household waste
✅ You transform organic waste into nutrient-rich compost
✅ You get fertile soil for your apartment plants
✅ Set a positive example in your community
✅ Reduce your carbon footprint

What can you compost?

YES (compostable materials)	NO (avoid this waste)
Vegetable and fruit peels	Meat, fish, dairy
Coffee grounds, tea bags	Oils, fats
Eggshells	Animal droppings
Leaves, dried flowers	Chemically treated products
Unwaxed cardboard, tissues	Plastic, metal, glass

Types of composting suitable for the apartment

1. Classic composting in a closed container

How it works: Special, aerated containers are used, into which compostable waste is placed.
Advantages: Simple, cheap, available online.
Disadvantages: Requires regular mixing and attention to moisture levels.
Tips: Choose a container with a lid, air filters and a drainage system.

2. Vermicomposting (with earthworms)

How it works: Red worms (Eisenia fetida) process organic waste and transform it into high-quality compost.
Advantages: Nutrient-rich, odor-free compost.
Disadvantages: Worms require a constant temperature (18–25°C); they can’t eat citrus fruits, onions, garlic.
Where to find earthworms: online or in garden stores.

3. Bokashi composting (anaerobic fermentation)

How it works: The scraps are placed in an airtight bucket with bokashi bran (which contains effective microorganisms).
Advantages: Fast process, can also include meat, dairy.
Disadvantages: It requires the purchase of bokashi bran constantly.
Ideal for: People who want to compost without turning or mixing the material.

Where can you keep the compost in the apartment?

Under the sink – ideal for vermicompost or bokashi.
On the balcony (closed) – classic container or vermicompost, sheltered from direct sunlight.
In the closet – if ventilated, it can be a discrete space.
In interior hallways away from strong light.

Recommendation: Choose compact containers with an airtight lid to avoid leaks and odors.

What do you do with the obtained compost?

Use it for plant pots (mixed with classic soil)
Give it to friends who have gardens
Donate it to local groups dedicated to urban agriculture
You can check if there is one in your city community compost collection center

Common problems and how to avoid them

Problem	Cause	Solution
Unpleasant smell	Too much wet material, lack of aeration	Add dry material (cardboard, paper) and mix
Flies/small insects	Exposed scraps, too much sugar	Cover the layers well and seal tightly
Compost too wet	Watery leftovers (melons, salads)	Add sawdust, shredded newspapers
Slow decomposition	Low temperature, lack of oxygen	Move the container to a warmer location and aerate it

Composting in your apartment – accessible sustainability

Whether you choose the worm method, bokashi or classic composting, apartment composting is a concrete step toward a more responsible lifestyle. You don’t need a big garden, just a corner of your apartment, a little willpower and curiosity.

Small gestures matter. A single liter of compost from otherwise discarded waste means less litter, less gas emissions and more natural food for your plants.
