Abstract: To clarify the actual state from generate of the construction and demolition waste to treatment and recycling, firstly, the authors made the field survey for 60 demolition works of wooden house in Japan to grasp the actual state of the generation of demolition wastes and clarified the relationship between a kind and quantity of the construction waste and the scale of houses. Additionary, to clarify the criteria for recycling in Japan, the authors made questionnaire survey of the criteria for intermediate treatment facilities when they accepted of the construction waste. As a result, it was revealed that intermediate treatment facilities look from a severe viewpoint for contamination on the occasion of acceptance of construction and demolition wastes. Finally, we investigated Life Cycle Assessment in the intermediate treatment to clarify the actual state. As for the breakdown of the Carbon dioxide emission in the intermediate treatment of construction wastes, transportation 50%, electricity 30%, heavy machine use 20%, the disposal less than 10%, and as for the amount of Carbon dioxide emissions was clarified that a high precision prediction is enabled from waste acceptance quantity.
