The residue from industrial factories and used plastics which are the leather waste from the tanning industry and polyethylene bottle waste being applied ascomposite and tested for the properties. There are two sections in this study. The first part is to find the suitable ratio of both materials for forming as a sheet. Next, the sheet would be tested for its properties. It was found that the suitable weight ratio of the leather waste is less than 40 percent. The tested specimens have tensile strength in the range of 15-19 MPa, elongation at break point in the range of 11-13 percent, modulus of elasticity in the range of 54-63 MPa, impact strength in the range of 5-8 kJ/m2, hardness in the range of 59-63 (shore D), thermal conductivity in the range of 0.05-0.07 W/m.C, water absorption (%) in the range of 0.4-5.3, water solubility (%) in the range of 0.3-3.4 and specific gravity in the range of 0.94-1.20.
