Abstract

The objective of this study was to estimate the practical recycling rate of plastic products, so that the study was conducted to build material flow diagram for PVC profile. For this objective, product generation, waste generation and recycling status were investigated. Using collected and analyzed status data, analysis of material flow by product and building material flow diagram were conducted. As result of estimating the recycling rate by product, The sum of domestic demand was 525,448 ton and waste generation was 105,853ton in PVC flooring and profile. The sum of generation of recycling product and raw material was investigated to be 76,004ton(14.46%), which is higher compared to recycling obligation(8.5%) in 2009. To build the material flow diagram in the years(5~20years) ahead, prediction of future demand was based on the assumption that there will be no difference in annual generation of current and future. As the recycling rate of flooring and profile increases, it is estimated to reach 20% in 2013 according to the material flow diagram.

본 연구에서는 현실적으로 실현가능한 플라스틱 제품의 재활용률을 산정하기 위하여 PVC프로파일에 대한 물질흐름도를 작성하는 것을 목적으로 연구가 수행되었다. 이를 위해 합성수지 및 제품별 생산 현황 조사, 폐기물 발생 및 재활용 현황 조사, 재활용 실태 현황 조사, 제품별 물질흐름 검토를 거쳐 내구성 플라스틱의 발생부터 폐기까지의 조사를 실시하여 물질흐름도를 작성하였다. 제품별 재활용이 가능한 비율을 산정한 결과, PVC바닥재와 PVC프로파일의 경우 국내에서 사용된 제품의 내수량의 합이 525,448톤이고, 폐기물 배출량은 105,853톤으로 나타났다. 재생제품과 재활용원료의 생산량 합계는 76,004톤으로 제품의 내수량에 대비하면 2009년 의무량 8.5%에 비교하여 연구를 통한 재활용량은 추정량 14.46%로 산출되었다. 향후 각 품목의 연도별 사용량은 해당제품의 생산량이 현재와 크게 차이가 없을 것으로 가정하고 연도별 생산량에 대입한 후 5~20년 뒤의 물질수지도를 작성한 결과, 재활용률은 지속적으로 상승하여 바닥재 및 프로파일은 2013년에 20% 수준의 재활용률에 도달될 것으로 예측되었다.
