ACE member companies are committed to sourcing their main raw material, wood fibre, from responsibly-managed forests. This ensures the forests remain a renewable resource for generations to come.
Growing more trees
In such forests, for every tree harvested at maturity, new saplings are planted or grow naturally. The majority of new trees are harvested during two thinnings: one at 25-35 years and one at 40-50 years. One tree is left growing to full maturity at 70-90 years before final felling.
Using wood fibre from forests with these sound management practices has a positive environmental outcome, as forest volume is actually increasing year on year: annual growth exceeds annual cuttings.
In Sweden and Finland, where most of the wood fibre for European beverage cartons originates, forests are expanding.
This means that the volume of the growing stock of forests in Sweden and Finland alone has almost doubled, increasing from 3.5 billion m³ in 1950 to 6 billion m³ today. (Source: Finnish Forest Research Institute).All parts of the tree are used
After the tree is harvested, every part of it is used most effectively: the thickest trunks and lower parts of trees are used for construction or furniture timber, the thinner parts (5-15cm) for paper and paperboard (pulp), and the rest (bark, small branches, sawdust) for bio-energy, particularly in the paper mills.
Beverage cartons, which are made from paperboard, only account for a small amount of the tree used. One average-sized thinned tree can provide wood fibre for around 1,500 one-litre beverage cartons.
