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!

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.
