Potato wastes liquefied in thepresence of polyethylene glycol/glycerin-dominant liquefaction reagent by usingsulphuric acid as catalyst in a microwave oven system under stirring. Theliquefied potato waste-based polyols were characterized for the preparation ofpolyurethane foams. The potato-based polyol which was obtained from 9% sulfuricacid catalyst within 30 min liquefaction reaction period was chosen for thepreparation of PU foams. Biodegradation and water absorption properties of PUfoams were measured and contrasted withsyntetic petroleum-based commercial foams. Prepared PU foam was cut into smallpieces of equal volume (10 mm x 10 mm x 10 mm) before biodegradation and waterintake test. Biodegrability of PU foam-based on liquefied potatowastes-contained foams was determined according to service biodegradation testfor three months. The mean amount of water absorption of potato wastes-based PU foams was measuredwithin 1, 2, 4, 8, 12, 24 and 48 hour. The weight losses (resulted from a3-month service biodegradation test) of the liquefied potato wastes-based foamsalong with commercial synthetic PU-type rigid foams had been found 17.84% and0,107% respectively. The mean amountwater intake at potato wastes-based PU foams were as to 137%, 156%, 226%, 249%,393%, 608%, 1,030% within 1, 2, 4, 8, 12, 24, and 48 hour respectively. Thesemeasurements were as to 35%, 42%, 52%, 65%, 76%, 84%, and 89% within 1, 2, 4,8, 12, 24, 48 hour at syntetic foams.Biodegradation and water absorption properties were found to be higher thanthose of petroleum-based PU foams dependently biomass content.
