폐인조잔디의 발생량 예측과 재활용량 산정 연구

This study was performed to prediction of generation and estimation of recycling value on waste artificial turf. The artificial turf consist of a different components by playground type, and combined of plastic, silica, and rubber materials. The weight per unit area of artificial turf is about 67.5% of the silica that is the highest, and infill rubber powder, pile, backing in order. As the result of investigation on artificial turf installation area from 2003 to 2012, the school playground is the largest portion because the development business plan of variety school grounds by government. And installed artificial turf will be discharge as the end of lifespan from 2011 to 2020. As the results of generation prediction by trend analysis, logarithmic function was estimated the most optimum method among the trend analysis. If 86.9% is recycled by Case II, the valuable materials of waste artificial turf was estimated that an annual average of about 2,990 tons of pile, about 2,177 tons of backing, about 52,803 tons of quartz sand, and about 20,241 tons of infill rubber powder in 2021 ~ 2040, respectively. It was evaluated to efficient recycling method of waste artificial turf that separated into the fabric and infill materials through first screening, and then infill materials separated into the silica and rubber powder through second screening.
