Against this backdrop, World PET sought a solu-
tion that would enable the recovery of high-qual-
ity PET material discarded with contaminants
while ensuring that the end product remained
free from metal impurities.
Sesotec´s partner in Portugal, Iberoacero pro-
vided a customized solution to this problem with
the installation of the RE-SORT RV 070 unit. This
advanced metal separation unit was designed to
inspect heavily contaminated material and sepa-
rate reusable PET from impurities. The RE-SORT
