국내 폐목재 발생량 예측 및 재활용 가치 추정

초록

This research was performed to evaluate the current and the future generation quantities of wood waste in Korea. Economical value of wood waste recycling was also evaluated. Wood wastes were classified by waste characteristics at source as forest, domestic, construction & demolition (C&D), or industrial wood waste. Each generation was found to vary in the region: In 2005, forest wood waste as the majority amounts to 35.2% (124,553 ton) of total quantity in the Joongbu region; domestic wood waste to 43.6% (359,854 ton) in the Sudokwon region; C&D wood waste to 70.4% (944,730 ton) in the Youngnam region; industrial wood waste to 39.3% (196,078 ton) in the Honam region. Multiple linear regression model properly described the future quantities of wood wastes from forest, domestic, industrial areas. Log trend method well predicted the future quantity from construction and demolition area. It was evaluated that C&D and forest wood wastes would occupy 31.3% and 29.2% of total quantity, respectively, in 2020. The generation of forest wood waste would grow by 347% in 2020 to reach 1,228,233 ton/year. It was revealed in this study that in term of economic, wood waste recycling can be an alternative to other treatment process, i.e., incineration and landfill, giving a big benefit of saving ￦582,246,000/day.
