QUESTIONS & ANSWERS


Everything you need to know about the KALEA kitchen composter

BIOLOGICAL PROCESS

icon_duration.png
How long does it take until KALEA turns my waste into fresh compost?

 

KALEA needs on average 48 hours for the composting process. But don't worry, thanks to our patented process, you can continuously throw your food leftovers into KALEA without having to wait until the composting is finished.

You can insert up to 10 liters of biowaste into KALEA
What kind of food can I insert into KALEA?

What KALEA will happily process for you: vegetables, fruit (including banana peels), leftovers, bread, bakery, processed food, dairy products, eggshells, tea bags, coffee ground, leaves. Moldy or not, doesn’t matter. Regarding the energy consumption during processing, we’d recommend waste that’s as dry as possible.
 

What you can add to KALEA in small amounts: meat, sausages, cheese, small (chicken) bones, small nutshells, (very) small twigs, single-use items marked as “biodegradable” or “compostable”.
 

What you should never fill into KALEA (because it wouldn’t compost in 48h or would harm the device): paper, large (pork, beef) bones, fruit stones bigger than 1 cm, threads, yarn, branches, wood, animal litter, and animal carcasses.

What is the difference between garden compost, fresh KALEA compost, and dried waste?

Garden compost is the most natural way to dispose of organic waste. If managed carefully, it leads to already matured compost. However, this takes a whole lot of time and specially cooked food shouldn't be treated this way since it attracts vermin. 


KALEA transforms the majority of compounds in your food scraps like sugar, starch, and proteins. These are broken down within 48h to fresh compost. If mixed with earth, fresh compost gives an immediate boost to your plants and realizes its nutritional potential. KALEA compost is so rich in nutrients that it can be mixed in a 1:10 ratio. This means 1 part KALEA compost with 10 parts soil. 


Food waste dryers do only one thing: shredding and drying food. There is no biological decomposition process involved. The organic compounds in this waste are thus inaccessible to plants. In some cases, using dried organic waste (often referred to as "fertilizer") can also cause mold and inhibit plant growth.

Can you compost cups or other single-use items labeled as “compostable”?

At the moment, we don’t recommend filling them into KALEA, as these special synthetic materials can’t be composted within 48 hours. Our team keeps on testing and tries to figure out how to handle and decompose these items as well. Safe to say is, though, that they shouldn’t do any harm to the compost quality.

Does anything except compost remain from my organic waste?

During composting, water may remain, as organic waste by nature consists largely of water. KALEA has a separate container box in which the water is collected. The water is very rich in nutrients, and you can use it to water your plants.

Are there any bad odors?

 

To ensure that your compost is processed odorless, we have implemented several technical features in KALEA, including an integrated active carbon filter.

KALEA accelerates the metabolism of microorganisms
How can my KALEA turn organic waste into compost so quickly?

 

Composting is done by microorganisms. These are naturally present on all organic matter and provide the necessary decomposition processes. 

In a compost pile in the garden, the biological process can only take place in the middle of the heap, where the heat is. That’s why you need to shift the material regularly. 

KALEA is able to accelerate the reproduction and metabolism of the microorganisms by means of intelligent control and sensor technology to such an extent that composting is possible in only 48 hours.

To answer this question, we also provide a lot of content on our website and blog.

What do I do with all of this compost?

 

10 liters of organic waste result in approx. 1.5 liters of fresh compost. You can mix it in a 1:10 ratio with regular soil, which means, 1 part KALEA compost with 10 parts soil.

 

When you still have leftover compost, you can store it for up to two years in an airtight, dry container in an environment where it’s protected from the sun.

 

Or gift it to your neighbors, your family & friends, or the plants in the park!

Does KALEA need an additive, like coco peat, to support the microorganisms?

No, KALEA does not require any additives. KALEA provides the microorganisms, which are a natural part of every organic material, with the perfect conditions, mainly in terms of humidity, temperature, and ventilation.

PRODUCT & TECHNICAL DATA

KALEA is 20x65x50cm wide, high, deep.
How big is a KALEA composter?

 

KALEA has a dimension of approx. 22,5 x 65 x 52 cm (width x height x depth).

KALEA is highly energy-efficient
How much power does the KALEA composter need?

 

KALEA is designed to be highly energy-efficient and also uses the heat generated during the composting process.

The power consumption of KALEA is estimated between 150 - 200 kWh / year for a four-person household. This is similar to the consumption of a coffee machine at home. For a two-person household, the consumption is around 75 - 100 kWh.

Simply plug it in and start composting!

How much biowaste can I insert into the KALEA composter?

 

Up to 10 liters of organic waste can be processed in each cycle. This results in a compost quantity of approx. 1.5 liters.

Does KALEA have a warranty?

We offer a standard warranty of 2 years, but everything is engineered with great care to last much longer than that, even under the highest usage. We will also set up partnerships in the countries we ship to so that if anything goes wrong, the issue can be solved within your home country.

How loud is KALEA?

KALEA works almost noiseless. In the drying and shredding mode after the input of organic waste, the volume is comparable to a washing machine. The volume of the later composting process is comparable to a dishwasher.

MAINTENANCE

What do I need to run KALEA?

 

KALEA comes with everything you need to produce your very own, fresh compost: the machine itself, a power adapter and an active carbon filter. All you need to get started is to plug it in and to have some kitchen leftovers ready!

How often do I have to change KALEA's integrated filter?

 

To ensure that your compost is processed odorless, we have integrated an active carbon filter in KALEA. Depending on how often you create compost and which food scraps you put inside, we recommend changing your KALEA filter every 3 to 6 months.


The filter packages will be available in our online shop or via our KALEA app as soon as we start distributing the first KALEA machines. We are looking at solutions for the most sustainable way to recycle the filter and even have plans for a reusable filter solution.

KALEA doesn't have to be cleaned
Do I need to clean the inside of my KALEA?

 

The feed chute and the compost container can be removed and put in the dishwasher. The rest does not need to be cleaned manually. KALEA takes care of this itself.
