Optical separators Sequence of single-valve separators 90.0% 90.0% 90.0% Two dual-valve optical separators 87.9% 87.9% 85.0% Thus, depending on the effectiveness and quality of each optical separator as determined by the manufacturer, the following overall effectiveness and quality is obtained for each optical separator sequence: In view of the data, it can be said that: • Single-valve optical separator configurations provide better results than dual-valve configurations. • The use of “plastic/non-plastic” configurations provide lower effectiveness due to the accumulation of errors. • Those configurations for separating mixed plastic as rejected waste from the chain obtain poor separation quality for this material. • More quality control staff is needed in configurations that select mixed plastic as a Efectivity Purity PM purity rejected waste from the chain. • The configuration of four single-valve optical separators provides the best effectiveness and quality, as well as requiring the fewest quality control sorting operators. • The use of recirculation increases the performance of the configuration but requires the use of larger optical separators. Four single-valve optical separators (plastic/ non-plastic) 83.7% 83.7% 56.5% Two dual-valve optical separators (plastic/ non-plastic) 80.1% 80.1% 52.3% Three single-valve optical separators (plastic/non-plastic) and dual-valve optical separator to recirculate plastics 91.1% 84.5% 59.8%
