520	3		_aThe exploration of effective utilization of greenhouse wastes is challenging. This paper demonstrates a hydrothermal treatment approach involving the co-liquefaction of greenhouse wastes with agricultural residue in a mixed solvent of water and ethanol in the presence of a base catalyst, to convert greenhouse wastes and corn stalk into bio-oil/bio-polyol at a very high yield of 57.2 percent, accompanied by a very low yield of solid residue. This bio-oil (hydroxyl number: 305?mg KOH/g)was successfully used as bio-polyol to substitute up to 50 percent petroleum-based polyol for the preparation of bio-polyurethane (BPU)foams. The biodegradability of the BPU foams was also studied by incubation with Dyella sp. for a period of 8?weeks. The weight loss, Fourier-transform infrared (FTIR)spectra, thermogravimetric analysis (TGA)results, and scanning electron microscopy (SEM)images of foam samples were collected and analyzed. The BPU foams exhibited much better biodegradability than the petroleum-based polyurethane (PU)foam.
