What is Ringelbox?
Ringelbox is a vermicomposter particularly designed for indoor use in kindergartens and schools. A special feature here is the transparent front wall, which offers a glimpse into the inner workings of the vermicomposter and thus brings children closer to the natural degradation processes.
It’s a whole ecosystem for kindergartens and schools!
Idea and team
We are building apartment-friendly vermicomposters, which are made out of recycled and recyclable materials, to
- reduce organic scraps in the residual waste
- prevent unpleasant smell
- create humus that is a valuable fertilizer for your own plants
- give children an insight of biological processes
The business model is simple and cost-effective, which makes the vermicomposters affordable for every household. We are currently in the process of setting up and testing out different prototypes.

Svenja Erfkämper is a Bachelor’s graduate in the program Sustainable Agriculture (B.Sc.), which focuses on sustainable food production. Through her degree program and internships at certified organic farms, she gained practical experience in soil science, especially in the use of nutrient cycles for food production. She has already successfully carried out projects on aquaponics and bee hotels, which included both the creation of a prototype and public relations.
Study course: Sustainable Development Management (M.A.), Faculty of Society and Economics
Sandra Neuhäuser is a Master’s graduate in the program Sustainable Development Management, in which the planning, implementation and evaluation of sustainable projects are addressed. She has already worked successfully as a project manager, where she was involved in coordinating teams and in customer acquisition. She also took part in a project for an Argentinian NGO to set up a sustainable waste incineration plant in a village. Furthermore, she has been supporting the education department at Amnesty International on a voluntary basis for years.
Seminars and workshops
The seminars and workshops we offer give the children an age-appropriate insight into ecological cycles using the Ringelbox and they learn a sense of responsibility in dealing with living beings. We also offer services for the maintenance of the Ringelbox and seminars on the subject.
Suitable for indoor use
Our Ringelbox is suitable for indoor use as it is small, odourless and easy to care for. The Ringelbox is also interesting for families, shared flats and individuals, as normal household organic waste is not wasted by being thrown away in the residual waste, but is recycled by the worms. As a result, the residual waste naturally does not form any unpleasant odours. In addition, the vermicomposter creates humus, which can be used as fertilizer for your own plants and crops.
For educational institutions
In our urbanized world we are increasingly alienated from nature. At the same time, it is increasingly important for us to pursue a more sustainable lifestyle. It starts with the youngest in our society - the children.
Ringelbox is particularly suitable for children, as it introduces them to biology in a playful and vivid way and promotes a sense of recycling. It is perfect for showing the children up close “what’s going on out there”.
At the same time, worms are living beings for which one takes responsibility. We support this educational offer with age-appropriate seminars and information materials for children and educators.
For families and individuals
You don’t have an organic waste bin and you don’t want to waste your organic scraps? Are you annoyed by the smelling residual waste? Or do you want your very own box-sized ecosystem? Then the Ringelbox is perfect for you! In addition to the odourless and sustainable composting of the organic waste, valuable worm humus is formed in the Ringelbox, which can be used as a plant fertilizer.
The fun factor that a vermicompost brings with it is not to be underestimated! The Ringelbox is available in different sizes and can therefore be adapted to your needs. Regardless of the size of the starting population, the worms multiply until their amount corresponds to the food available. The Ringelbox is suitable for families, shared apartments and individuals.
How it works
A lot of compost worms live in the Ringelbox along with even more microbes. If you put the organic waste on top of it, it will be decomposed by them - in such a way that no unpleasant smells can form. After a while, the organic waste becomes worm humus, a very valuable organic fertilizer. Its advantages are the many plant-promoting components (microorganisms and enzymes) that cannot be found in any other fertilizer or soil improver. Furthermore, the plants can selectively extract the nutrients from the worm humus so that they cannot be over-fertilized.
When one side is filled, remove the top layer and fill the other side with it. From there you feed the worms for about 2 weeks, until they have all migrated through the grid and you can easily remove the worm humus (see care instructions: Help! My Ringelbox is full).
