EVALUATION OF THE SCENARIOS FOR RECYCLING OF DEMOLITION WOOD WASTE FROM RESIDENTIAL HOUSES

Abstract

Three scenarios for recycling of demolition wood waste from residential houses were compared in terms of the recycling rate and reduction of the new wood input. Respective scenarios included the incineration, recycling as raw materials for paper and wood composite board, and reusing as constructive members of residential houses. The results were as follows: 1) reuse of lumber as well as diverse use of wood waste chips were effective to reduce the amount of wood waste; 2) improving the reuse rate of lumber was effective to reduce both the amount of waste and the input of new wood into construction of houses; 3) an increase in the demand for wood waste chips reduced the amount of waste but did not greatly affect the input of new wood.
