Integrated process for treating recycled streams of PET and PTT

A process comprising reacting

• (a.) polyethylene terephthalate or polytrimethylene terephthalate;
• (b.) polyurethane flexible foam;
• and
• (c.) a glycol
• in a reactor comprising a mixer, thereby forming a completely digested intermediate stream comprising a polyol and an undigested stream comprising contaminants;
• separating the undigested stream from the completely digested intermediate, thereby forming a separated digested intermediate stream;
• and
• reacting the digested intermediate stream with a hydrophobe selected from oleic acid, ricinoleic acid, tung oil, corn oil, canola oil, soybean oil, sunflower oil, bacterial oil, yeast oil, algae oil, castor oil, triglycerides or alkyl carboxylate esters having saturated or unsaturated C6-C36 fatty acid units, saturated or unsaturated C6-C36 fatty acids, alkoxylated castor oil, saturated or unsaturated C9-C18 dicarboxylic acids or diols, cardanol-based products, recycled cooking oil, branched or linear C6-C36 fatty alcohols, hydroxy-functional materials derived from epoxidized, ozonized, or hydroformylated fatty esters or acids, or mixtures thereof.
