廢機動車輛粉碎殘餘物(ASR)組成複雜，分選處理困難，目前多以焚化處理。然而，面對焚化處理成本增加及環境展望，應思考將廢機動車輛粉碎殘餘物(ASR)予以回收再利用。由於ASR中組成分密度差異大，本研究先以浮選方式分離輕質塑膠，如 PE、PP、PU等。再以水力漩流(hydrocyclone)分離技術為基礎，將差異大(比重)之物質分離選別，分成重塑料， PVC、礦物(玻璃、土砂)、金屬等三股物質流。隨後更以流場電腦模擬FLUENT-計算流體力學(Computational Fluid Dynamics, CFD)技術，輔助操作條件與增進效能。 經分選物質，玻璃、土砂經確認環境友善性後再利用;而輕質塑膠、重質塑料、玻璃、土砂等可依個別特性製成隔音芯材、戶外型再生板磚、室內輕質流漿牆等功能性產品，並驗證產品功能性、環境友善性特性。如此，解決國內ASR焚燒去化問題，產製高值化產品，降低環境負荷，創造綠色經濟。達成環保永續使命。

Automobile Shredder Residue (ASR) is usually incinerated in Taiwan. A flotation process could separate light plastics such as polyurethane (PU), polyethylene (PE), polypropylene (PP) textile, firstly. After that, the two-step hydrocyclone separation process could separate the ASR into three principal components the light-mass flow (plastics, such as polyvinylchloride (PVC)) and two heavy-mass flow (metals and minerals (glass/stones)). Furthermore, the FLUENT flow simulations were help to calculate the fractional efficiencies in hydrocyclone separators. The separated minerals (glass/stones) is tested by column test, the obtained sub-samples are recycling for producing functional materials such as sound-absorbing material, acoustic barrier, high-pressure manufactured bricks and light-weight concrete wall product. These products undergo leaching tests and characteristic inspection. Accordingly, the ASR by-product functional materials could be promoted for use the resource recycling target was achieved.
