About the brand

As a family-run company, we don't think in quarters, but in generations. That's why we have always tried to harmonize our production requirements with the idea of ​​sustainability.

We keep our ecological footprint as low as possible, also taking economic and social aspects into account. So that we can not only offer future generations useful and valuable teaching and learning materials/games, but also preserve a planet worth living in. 

For this reason, our products are mostly made from the recycled materials RE-Wood® and RE-Plastic®. At RE-Wood® we only use 100% recycled wood residues and consistently return the raw materials used to their product cycle. Cradle to cradle.
We reuse production waste and thus achieve material utilization of over 98%. When it comes to packaging material, we largely avoid plastic films and only use cardboard material.

Through our regional and personal collaboration with our suppliers, we can implement our high sustainability requirements and check them at any time. We do not use any toxic or environmentally hazardous substances.

Through state-of-the-art production facilities and the use of solar energy, we achieve almost CO2-neutral production. Even when shipping, we ensure compliance with sustainability and CO2 neutrality.
