RESEARCH ON CURRENT SITUATION OF MATERIAL FLOW OF WOODEN CONSTRUCTION MATERIAL IN AKITA PREFECTURE AND ENVIRONMENTAL EVALUATION OF RECYCLING

Abstract

Wood is the one of three main construction materials. Comparing to other two, Iron and Concrete, recycling rate of wood is low and its material flow is not clear yet. One reason of such situation is that there are so many recycling methods of wood. In this research, we tried to make real situation clear concerning about wooden construction materials which manufactured in Akita prefecture. Then we tried to evaluate effects of recycling in some lumber factories using Life Cycle Assessment tool.
