Plastic is one of the most widely used materials in our daily life and industry. Recycling is an important activity in the minimization of waste that results from human activities. Depending on plastics surface characteristics, they can be separated from each other by flotation method which is useful mineral processing technique with its low cost and simplicity. To succeed in a separation of mixed polymers based on polymer type using selective flotation, it is necessary to render one surface more hydrophilic while the others are still in a hydrophobic state. The separation could be achieved with the help of appropriate plasticizer.
