    This work investigated different brands of waste refrigerators properties in terms of the recycled acrylonitrile-butadiene-styrene (ABS) using solvent recycling technique at room temperature. The preliminary analysis showed that, tetrahydrofuran (THF) was the most suitable solvent among others, because it has solubility parameter of 9.79 cal/cm3, which was closest to the solubility parameter of acrylonitrile-butadiene-styrene (ABS) of 9.4 cal/cm3. The FTIR analysis indicated presence of ABS in recycled materials from all the refrigerator brands. However, the recycled ABS from Matsui fridge was found to have mechanical properties closest of the virgin acrylonitrile-butadiene-styrene whose tensile strength, modulus of elasticity and flexural strength were 31.66, 1021 and 60.18 MPa respectively, as compared to the virgin ABS with 48.3, 1312 and 65.75 MPa respectively. It is concluded based on the investigation that, the recycled ABS from Matsui fridge model has the best mechanical properties when compared to the others, as it values are closer to that of virgin ABS.
