A process for producing a polyester polyol comprising reacting a recycle stream selected from recycled PET carpet, carpet fiber, containers, textiles, articles or mixtures thereof, with a glycol in a reactor, thereby forming a digested product stream comprising polyols, and an undigested stream; and then reacting the digested product stream with a hydrophobe selected from dimer fatty acids, trimer fatty acids, 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 C-Cfatty acid units, saturated or unsaturated C-Cfatty acids, alkoxylated castor oil, saturated or unsaturated C-Cdicarboxylic acids or diols, cardanol-based products, recycled cooking oil, branched or linear C-Cfatty alcohols, hydroxy-functional materials derived from epoxidized, ozonized, or hydroformylated fatty esters or acids, or mixtures thereof. 129.-. (canceled)30. A process comprising:(a) reacting a recycle stream comprising recycled carpet selected from PTT carpet, PET carpet or mixtures thereof, with a glycol in a reactor, thereby forming a completely digested product stream comprising polyols, and at least one undigested stream;(b) separating the completely digested product stream from the undigested stream, thereby forming a separated digested product stream and a separated undigested product stream; and{'sub': 6', '36', '6', '36', '9', '18', '6', '36, '(b) reacting the separated digested product stream in the reactor with a hydrophobe selected from dimer fatty acids, trimer fatty acids, 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 C-Cfatty acid units, saturated or unsaturated C-Cfatty acids, alkoxylated castor oil, saturated or unsaturated C-Cdicarboxylic acids, cardanol- ...
