Statistic data indicates that about 100,000 tones of waste tire were generated each year. Current recycling market of waste tire is very small. Therefore, many waste tires remain untreated and cause severe health and safety problems in storage. PP fiber cut end is the waste material after cutting off the fiber. Traditional reuse way was to be the toy¡¦s fillers. If we can reuse the materials properly to develop a market of additional value, it will be a big contribution to the society. In this research, recycled waste tire powder and PP fiber cut end are used as oil adsorbents for the purpose of oil recovery during the process of oil spill emergency response. PP fiber cut end and waste tire powder are capable of adsorbing oil due to their hydrophobic surface property and the capillary forces developed during the contact with oil, therefore, makes them a perfect material for oil recovery. The major advantage of recycled PP fiber cut end is its high oil adsorbing capacity (approximately 48.4g/g). But, after reuse, its oil adsorbing speed was slow down, so does the oil adsorbing capacity. On the other hand, with good elasticity, the waste tire powder can be reused for more than 100 times without loosing its capability. However, the oil adsorbing capacity of waste tire powder is far less than PP fiber (approximately 2.84g/g). Finally, we combine PP fiber cut end and waste tire powder, to see if we can take the advantage of each product and make the best utilization of the composite material. Results indicate the composite material can be reused for more than 100 times without loosing its capability, and its performance is even better than the combination of each individual product. In the other test, we can see the composite material can not only adsorb engine oil and crude oil, but also adsorb emulsified oil. In the test, the composite material can recover up to 28 times of its own weight of oil. With the invented set up, the oil recover work is much easier to operate, and moreover, the composite material is less expensive. Only a squeeze roller and a collection container are required to recover oil. So, the composite material is indeed having practicability and mobility. Finally, the composite material is an excellent adsorbent compares with other products available on the market.
