Is it possible to separate heavy metals in the Vinyloop® process?
In the current industrial projects, we will not be able to separate the heavy metals (Lead, cadmium,…) from the recycled PVC compound. Absence of lead within the regenerated PVC compound can only be achieved through a selection of the in-flows in the system. Nevertheless, preliminary research indicates that it is feasible, but what should be done with the heavy metals once removed? The Voluntary Commitment of the Vinyls Industry states about the phase out of lead and cadmium from virgin product and – as long as no inacceptable risk about the use of lead and cadmium stabilisers is identified – reccommends to accept recyclate containing those metals to avoid their dissemination in the environment.
