Make your own compost with a Balkonton – even in the city!

A Balkonton is always and everywhere!

A Balkonton is a small composter housing compost worms. It takes up little space, does not smell, and can be used both indoors and outdoors – meaning you don’t need a balcony to have a Balkonton. Make your own compost with Balkonton on a roof terrace, in the kitchen, in your city garden or on your patio. The composters are simple and odourless: compost worms eat uncooked fruit and vegetable scraps, alternated with more carbon-rich waste such as cardboard, sawdust or dead leaves. They also love coffee grounds! The worms speed up the composting process and immediately improve the quality of your compost. Among all the different kinds of Balkonton, the compost worms will get to work with your waste quickly and in a controlled manner.


Hi! I’m Ireen, founder and owner of Balkonton. You can always arrange an appointment to come see the different worm composters in action at my home in Amsterdam Noord. As the stock is in Groningen, though, pick-up in Amsterdam is not possible. Do you have questions that are not answered in the FAQ? Then please feel free to call me during office hours, I’ll be happy to help you +3138553833.

Frequently Asked Questions

What do the worms in composters eat?

Illustration yellow wormThe worms eat a mix of carbon- (brown) and nitrogen-rich (green) waste. Please note to not give your worms ‘red’ waste (see red block below).

Make sure to alternate between ‘brown’ and ‘green’ waste. This is important for the moisture balance and the acidity.

Brown, high in carbon:
Cardboard, paper, shredded prunings, sawdust, dead leaves, straw, hay, corn on the cob.

Green, high in nitrogen:
Uncooked garden and kitchen waste, potato peelings, fruit and vegetable residues, banana peels (preferably from organic bananas), manure from small herbivores such as guinea pigs or rabbits, remains from vegetable and ornamental gardens, pruning waste (green), coffee grounds.

Red, never give the worms any of the following:
Cooked vegetable and fruit remains, pasta, bread, meat, bones etc. (attracts vermin), cut flowers (contains lots of poison). Go easy with the onion, garlic, chilies, and avoid citrus peels. Furthermore, do not feed the worms green waste that is clearly contaminated with fungi or diseases.

“We purchased the round Balkonton and are very satisfied. After three months we even expanded with an extra plant ring, since as a family of five we eat quite a lot of vegetables.”
