Compostella's transparent paper sleeves are pure paper products that do entirely without fossil raw materials in the course of production. Due to the chlorine-free bleached cellulose, they are both recyclable and fully compostable. And thanks to the high transparency, it is also possible to scan and copy documents without removing them from the sleeves. Production is carried out using machines powered by photovoltaic electricity from solar modules on the roof of the company building. The paper comes from a regional paper mill.
