Flotation process for plastics in waste streams

The purpose of the project is to investigate whether flotation techniques, a technique commonly used to purify water or enriched ore, can be used to separate the plastics waste plasters when not gravimetric separation works. The project will determine possible separation efficiency in laboratory scale and demonstrate flotation separation with various plastic samples. Flotation is a promising method of separation of plastic waste and more efforts are required to achieve industrial application. A developed flotation technology leads to increased competitiveness for Swedish players.
