Abstract

The objective of this study was to investigate the feasibility of recovering the polyols from the polyurethane (PU) foam obtained from waste upholstered furniture (sofa) by chemical decomposition using the propylene glycol (PPG) as the decomposing solvent and sodium hydroxide (NaOH) as the catalyst, respectively. The effects of temperature (180°C and 200°C), reaction time (0.5, 1, 1.5, 2, 2.5, and 3 hours), and PPG/PU weight ratio (2:1, 3:1, and 4:1) on the decomposition reaction and the physicochemical properties of the recovered polyols, such as hydroxyl number, viscosity, and amine number were investigated. Higher temperature and PPG/PU weight ratio promoted the PU decomposition reaction and resulted in lower viscosity, higher hydroxyl number, and higher amine number of the recovered polyols. The hydroxyl number and amine number increased as the reaction progressed, while the viscosity decreased. Once the reaction was completed, little change was observed for the hydroxyl number and viscosity of the recovered polyols. The recovered polyol obtained at 200°Cand PPG/PU weight ratio of 3:1 showed about the same length of time for the reaction, as well as the physical properties to that obtained at 180°C and PPG/PU weight ratio of 4:1. These recovered polyols had similar hydroxyl number and viscosity to those of commercial polyol used for PU coatings, elastomers, adhesives, and sealants.
