Titel
Effective Recycling of Valuable Plastics by Selective Extraction
Alternative
Effektives Recycling verwertbarer Plastikabfälle durch Selektive Extraktion
Abstract
Selective extraction, a new recycling method, provides the potential for obtaining pure recyclates with original properties out of postconsumer plastic mixtures. The essential steps involved are selectively dissolving the target polymer, refining the polymer solution and precipitating the target polymer from the solution. Selective extraction allows one to remove externally adherent contamination and, unlike methods employing melt technologies, it allows one to remove contaminants from the original polymer matrix. This technology has been investigated for different polymer-solvent systems as well as for different applications with their corresponding circumstances and objectives.
