A6 notebook with approx. 72 sheets/144 pages of lined, recycled paper (120 g/m²) made from 80% stone waste with a little resin (HDPE) to bind the stone powder. Far less raw materials are needed for this production and no bleaching agents or toxic substances are used. The notebook has a spiral bound. The cover made of bamboo wood has a longer lifespan than regular wood. Bamboo can be harvested within 5 years (trees need 30 - 120 years!) and 4 to 7 new plants grow from the remaining roots! This notebook is a typical cradle-to-cradle product with certified material that can be infinitely recycled.
