Automatic kitchen composter:
An alliance between nature
& smart technology

Compost in 48 hours! 

This is how nature and tech work together


Natural components of every food are microorganisms. Such as bacteria and fungi.

They decompose the waste – and we use their superpowers in a smart new way. 


Speed it up! The inside of KALEA is equipped with sensors and an intelligent control system, which accelerates the required metabolism needed. A combination of the perfect temperature, humidity, and aeration turn your food waste into a land of milk and honey for microorganisms. The result? KALEA is able to substantially reduce the composting time from several weeks to only 48 hours.


Clean, convenient, and safe: The automatic grinding, mixing, and transfer of biomass ensure that you have nothing to take care of – except your excitement about fresh compost. 

KALEA combines high-quality components with smart design



Space for everything! Easy to clean and just as easy to operate. Kitchen waste of up to 15 x 15 cm can simply be added.



Collecting, grinding, and drying of kitchen waste.

New waste can be added at any time.

With a unique grinding mechanism, KALEA processes all kinds of kitchen waste - even small bones and nutshells. Thanks to a large capacity, KALEA can collect kitchen waste of 3 to 4 days.




Super silent and extra fast. As soon as enough food scraps have been added (10l), KALEA automatically transfers the pre-processed material into the composting chamber.

During the next 48h, all material converts into ready-to-use compost.



Every second on point. Various sensors measure and control temperature, humidity, and ventilation.

This way, KALEA guarantees optimal metabolic conditions for the microorganisms, and thus ensures the fastest possible composting.





Composting is a hot thing! KALEA extracts the heat generated during composting and reuses it to dry the waste.

A win-win situation, since it saves energy and dehumidifies the exhaust air.



Water is a valuable resource. KALEA does not require any additional water, as organic waste by nature already consists largely of water.

During composting, water may remain. It is very rich in nutrients - you can use it to water your plants.





Ciao, stinky garbage! Our large filter and its unique vacuum technology release the exhaust air solely.

Special integrated active carbon efficiently removes all bad odors.

The thing about composting


Your organic waste is a bit like a fresh and full shopping bag. In order for your plants to use the nutrients, the "bag" must first be unpacked. This unpacking is called remineralization.


During the remineralization process, organic molecules are converted into inorganic minerals. This conversion is mainly done by omnipresent microorganisms such as bacteria and fungi, which are a natural part of our food.


During composting, the sugars, starch, proteins, fats, and at a later stage, cellulose is present in the waste that is broken down.

The compost quality can be influenced by providing optimal metabolic conditions for the microorganisms over a certain period of time. These conditions include temperature, pH value, moisture, amount of oxygen, and surface area. The better the conditions are met, the faster high-quality-compost is achieved.

KALEA is the fastest way to create more out of your organic waste


For your plants and for planet Earth

Biowaste in landfills significantly damages our climate

Did you know that incorrectly disposed biowaste is more dangerous for the climate than CO2? 

When organic waste is dumped in a landfill, it undergoes anaerobic decomposition (because of the lack of oxygen) and generates methane gas. Methane gas is a potent greenhouse gas – about 28 times more powerful than carbon dioxide at warming the Earth, on a 100-year timescale, and more than 80 times more powerful over 20 years.


Worldwide organic waste accounts for about 50% of the total amount of waste. Burying organic waste in landfills is a significant problem and it’s not just because of the resources we lose.

This is one of the reasons why we wanted to bring a change to your daily waste game. Make an eco-friendly difference with KALEA.

An electric composter for your kitchen - home composting made convenient with KALEA 

Are you looking for a sustainable and convenient way for food recycling? Such as a mini-compost pile for your home, but without the smell, flies and mess? KALEA has developed an electric kitchen composter, which is the first indoor composter of its kind and suits all of your food composting needs.  


Interested in making compost at home? KALEA turns your organic waste into fresh compost automatically, hygienically, safely, and without odour in just 48 hours. 


An electric composter in the kitchen saves you from having to walk up and down stairs, and even without your own garden or balcony you can make something useful out of your organic waste. Our unique composting system combines nature with high tech, and allows you to compost at home hassle free. 


Our KALEA kitchen composter can process more than just fruits and vegetables. You can also put nutshells, fish, small bones, dairy products and cooked food in the organic composter.

With an automatic composter bin you can make something truly useful for your plants! 


The nutrient-rich compost produced from organic waste in our electric composter contains all the essential nutrients and minerals that plants need to grow. Simply mix the compost in a ratio of 1 to 10 with fresh, peat-free soil. You can use it for your indoor plants or outside in the garden. The best thing? The compost produced from our automatic composter can even be stored for up to two years. 


Ask yourself: Which kitchen composter is the right one for me? We say: KALEA! Because composting at home has never been so easy. In October 2020, our crowdfunding campaign will begin. Our newsletter is the best place to get updates about the campaign, including when it will start. Exclusive perks will be available through our crowdfunding campaign, including discounts up to 50% off the KALEA composter.
