Utilisation of by-products in the forest-products industry has
developed in response to various operational problems that have
been experienced (Hahn, 1982; Ilomäki and Melanen, 2001; Lu
et al., 2006). Therefore, in the present study, it was expected that
the operational problems experienced by the businesses under
investigation would also influence the methods adopted to utilise
waste materials; however, the results did not support this assumption.
Only 1 of 23 businesses that stated that they were short of
capital utilised their waste by selling it rather than using it to meet
their own fuel needs.
