AbstractIn this paper we present the main technologies developed over the last decades on chemicalrecycle of PET from a practical and economical point of view. We show details of plants usedto carry out solvolitic reactions emphasising steps of purification, which are sometimes notconsidered when discussing chemical, recycle but which, in fact, are the key feasibility factors.The recycling or modification of PET to obtain monomers and other useful chemicals asintermediates and additives is carefully considered.
