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.
