Hardwoods are in plentiful supply.
Wood residues are chips, shavings and sawdust left over from logging and saw-milling operations for the furniture and construction industries. And the recycled content of paper-based packaging continues to rise. Sixty percent of all such packaging shipped domestically was recycled fibre in 1996. Unlike softwoods, where there is generally sufficient wood residue to meet the needs of mills requiring such fibre, hardwood residue is not available in the quantities needed by semi-chemical corrugating medium facilities. Their hardwood fibre furnish must therefore be met by using logs which are in plentiful supply.
