Metsä Group's Äänekoski mill in Finland now calls itself a ‘bioproducts mill’ as it makes paper and wood for recyclable drinks cartons, clothing and building materials. They re-use the chemical additives and by-products of the production process to make sure they are not wasted. They also deploy drones to digitally map the forest area so they can monitor trees using a mobile phone app and then arrange remotely for contractors to thin or harvest an area when the trees look ready.
