METHOD AND APPARATUS FOR THE RECYCLING OF POLYMERIC MATERIALS VIA DEPOLYMERIZATION PROCESS

摘要

In a method and an apparatus for the recycling of polymeric materials, more specifically polyesters and polyamides, via depolymerization process, the depolymerization reaction of the material to be treated is performed with a solvolytic mixture in at least one microwave depolymerization reactor (6) which extends substantially along an axis (A) and is provided with a system (7) for movement of the reactants which allows the reactor (6) to operate continuously; the movement system (7) is an Archimedean screw system which moves the reactants substantially along the axis (A) through the reactor (6).
