Analysis of the Utilization Structure of Wood Material and Energy Adopting Resource Accounting Approach

Abstract

Wood biomass supplied by the forestry and wood industry complex is recognized as the major source of woody bioenergy. The forestry and wood industries are strongly interdependent, and wood biomass supply is thought to be readily influenced by the performance of this industrial complex. We need to understand wood utilization activities to clarify the linkage between the performance of the complex and wood biomass supply. First, we calculated the use of wood material and energy in 2000 and 2011 using the same method. Then, the difference between the 2 years was determined. This showed that the increased demand for plywood production during the 10-year period was not met by the domestic input of wood. Therefore, the supply of bioenergy decreased because byproducts from the wood industry had decreased along with the decrease in total wood consumption during that period. Basing on the linkage between the industry complex and woody bioenergy supply, further bioenergy use should be enhanced and the use of wood material increased.
