Industrial systems and daily life in Japan are shifting to a society based on recycling to reduce energy and resource consumption and efficient separation technology of valuable component from used products is important. The authors have developed the RETAC jig (a modified TACUB jig) and the RETAC jig can separate relatively low density particles such as plastics. To further improve the separation ability, a hybrid jig (a RETAC jig with an air bubbler under the particle bed), which can separate plastics having similar specific gravities by the differences in the wettabilities of the particles was developed. Surface modification of plastics with similar wettability enabling separation in the hybrid jig and precise control of the wettability of plastic surfaces are investigated. Effect of bubble size on apparent density of particles was also investigated and recovery system of floating and suspending particles was developed.

日本的工业系统和日常生活正在向基于回收的社会转变，以减少能源和资源消耗，有效分离有用成分的技术非常重要。作者开发了RETAC跳汰机（一种改进的TACUB跳汰机），RETAC跳汰机可以分离相对低密度的颗粒，如塑料。为了进一步提高分离能力，开发了混合跳汰机（在颗粒床下具有空气鼓泡器的RETAC跳汰机），其可以通过颗粒的润湿性的差异分离具有相似比重的塑料。研究了具有相似润湿性的塑料表面改性，使混合夹具中的分离和塑料表面润湿性的精确控制成为可能。研究了气泡尺寸对颗粒表观密度的影响，并开发了漂浮和悬浮颗粒的回收系统。
