- Abstract
- Waste deposit & refund system was performed in order to recycle the waste since 1992, and this system developed into the EPR (Extended Producer Responsibility) system since 2003 in Korea. Many products and packaging materials are recycled by this system, and government published the ‘EPR Practical Manual (2007)’ to estimate the actual recycling rate. According to styrofoam-buoy (SB) included EPR item in 2010, SB does not practical to estimate the recycling rate, EPS (Expanded Poly-Styrene) was recycled only. So in this study, SB recycling rate also includes ‘EPS + parts’ was to estimate through the field investigation. As a results, parts portion of SB are 3.49% when manufactured, and 2.03% when recycled. And process loss, contaminant content, parts portion and yield of EPS ingot are 0.00%, 64.28%, 0.71% and 35.01% in SB recycling, respectively. In the future SB recycling rate is calculated by adding the EPS ingot production and parts recovered.
