Frequently asked questions

Here you will find the answers to the most common questions about kitchen composters  Bokashi Organko and Bokashi Organko 2. If you have any additional questions, do not hesitate to email us at .

1. How does the composting system in the kitchen composters Bokashi Organko and Bokashi Organko 2 work?
Organic waste placed into kitchen composters Bokashi Organko and Bokashi Organko 2 does not rot - it is fermented instead. We ensure that an odorless fermentation process takes place inside the composter by adding the biogen bran, which contains effective microorganisms. By adding the biogen bran, we not only assist and speed up the fermentation process, but also subsequently prevent decay, the formation of unpleasant odors and the attraction of various insects.

2. What can I put into kitchen composters Bokashi Organko and Bokashi Organko 2?
You can put all types of organic waste into Bokashi Organko: fruits and vegetables, citrus and banana peels, prepared food, cooked and raw meat, fish, yoghurt, cheese, eggs, smaller bones, bread, coffee grounds, tea bags, flowers and smaller amounts of tissue paper.

3. What shouldn’t I put into Bokashi Organko and Bokashi Organko 2?
You should not put liquids (water, milk, juice, vinegar, oil), paper, plastic, large bones, ash and animal feces into your composter.

4. What is Biogen bran?
Biogen bran is a mixture of bran, mixed with molasses (sugar and water), enriched with useful microorganisms (lactic acid bacteria, yeasts, photosynthetic organisms, actinomycetes and enzymatically active fungi), that cause fermentation.

5. How often should I add Biogen bran?
Biogen bran should be added every time you add a new layer of organic waste into your composter.

6. How much Biogen bran do I need?
Biogen bran should be added every time you add a new layer of organic waste, as it is crucial in beginning the process of fermentation. Fermentation prevents rotting and is not accompanied by any unpleasant smells. With regular use of your composter, 1kg of biogen bran should hold for about 30 days.

7. Are the microorganisms in Biogen bran safe?
Of course! The microorganisms are Nassa and BFA certified. They are also a natural part of our everyday diet (they can be found in cheese, wine, yogurt, etc.).

8. How can I use the fermentation liquid?
The fermentation liquid is full of microorganisms and nutrients. It can be diluted with water and used for watering potted and garden plants - it is a great fertilizer. UNDILUTED fermentation liquid SHOULD NOT be used for watering potted and garden plants! You can pour undiluted fermentation liquid into your toilet or purification plant. The microorganisms will dissolve any toilet paper, fat and remains of detergents or washing powder. The liquid can also be poured into a sink or wash basin to prevent the accumulation of fat and other substances in the siphons. This way, they will always stay clean and functional.

9. How much fermentation liquid will I get from my composter?
The amount of fermentation liquid that will be obtained depends on the variety of added organic waste. For example, a lot of added fruit will give you a lot of liquid, but if you add a lot of cooked food, vegetable and bread, then there will be less liquid. The amount of fermentation liquid produced is not an indicator of whether the system works or not and you will not get it any more or less if you add more or less biogen bran.

10. What happens if I go on vacation?
It is a great opportunity to finish the fermentation process inside your composter. Before you leave, drain the liquid from composter. Make sure there is enough biogen bran on top of the organic waste and that the lid is closed tightly. Then you can forget all about it until the end of your vacation. While you are away, the microorganisms will process your organic waste and you will be able to use it in your garden when you come back.

11. Is fermentation better than classic composting?
While a compost is a very good source of nutrients for your garden, many useful substances are lost during the classic (thermophilic) composting process. In the process of fermentation, the waste does not lose any of its energy, nutrients or minerals. And unlike with rotting, there are no greenhouse gases emitted in the process of fermentation.

12. How often should I clean my kitchen composters Bokashi Organko and Bokashi Organko 2?
The composter should be cleaned only after it has been emptied. It is enough to simply rinse it with running water. Do not add detergent, because it can kill the microorganisms and thus disrupt the natural environment created in your composter.

13. Can the waste in composter get a bad smell?
If your composter is used correctly, its contents should not smell. It can have the smell of vegetables and fruits that were collected and put into it, but it should not have an unpleasant smell. If this does happen however, it means something went wrong during the process of collecting waste: perhaps the lid was not closed properly or the top layer of waste was not covered with enough biogen bran. You should also check if you have drained all the fermented liquid. Finally, always make sure the waste is tightly pressed together in order to prevent air pockets from forming, as those can release an unpleasant smell. If the odor ever becomes very unpleasant, empty your composter into your garden compost or the outside container for biological waste, rinse it thoroughly with water (no detergent) and start anew.

14. What should I do if mould appears on top of the waste?
The mould that appears can be light (white) or dark. White mould can appear when you fill the composter very slowly and there is a lot of air in it. White mould is beneficial. If it bothers you, you can put a piece of thick paper on top of the waste after you have covered it with biogen bran. Dark mould usually appears if you did something wrong in the process. Perhaps you did not keep the container closed, added too little biogen bran, added biogen bran irregularly or neglected to drain the fermentation liquid regularly. In this case, empty the composter in your garden, add an equal amount of biogen bran as there is waste, cover it with soil and leave it for 4 weeks. You can use it in your garden after that time period passes.

15. Where can I buy new packages of biogen bran?
Biogen bran can be ordered in our online shop.

16. The waste doesn't seem to have decomposed in the composter. What is wrong?
A simple indicator that suggests the proper functioning of the process is the smell. If there is no bad smell of rot, then the fermentation process has worked. The shape and color of the waste we put into the composter will remain unchanged even after the process has finished. Decomposition into humus form occurs when the already fermented mass of organic waste is buried into the soil. Here the decomposition occurs very quickly because the mass was previously correctly fermented and thus it changes into humus in a couple of weeks (depending on the time and temperature of the soil).
