Flotation separation takes advantage of PETs behaviour in water, which changes after being treated with a strongly alkaline chemical such as sodium hydroxide. The behaviour of PVC, on the other hand, does not change. Whilst PET sinks in water after treatment, PVC floats. On this basis, the researchers were able to recover the PVC
