Environmentally-friendly reforestation: Biodegradable tree covers made from renewable raw materials.
In reforestation projects, the seedlings must be protected. So-called growth covers prevent game from feeding on the young plants and help to ensure that they are not prevented from growing by other plants. Previously used sheaths made of plastic and metal are often not removed in time and pollute the environment. The DITF have developed a biodegradable yarn for growth covers from renewable raw materials.
