THE EFFECT OF ADDITION BY BUTHYLATED HYDROXYTOLUENE (BHT) ON PHYSICAL PROPERTIES OF GEOMEMBRANE FROM RECYCLED HIGH DENSTY POLYETHYLENE (HFPE) PLASTIC WASTE

Recycled High Density Polyethylene (HDPE) has been prepared for geomembrane construction material. The aim of this research was to study the effect Butylated Hydroxytoluene (BHT) addition as an antioxidant on characteristics resulting geomembrane. Fourier Transform Infra Red (FTIR) analysis carried out examine functional groups recycled HDPE and geomembranes. Mechanical properties, permeability hydrophobicity were observed determined optimum BHT addition. results FTIR showed presence at wavelengths 2912 2847 cm-1 (C-H stretching); 1474 1467 (CH2 bend); 721 Rock). After being formulated with other materials obtain geomembranes, it not found new peak indicating that in only physical interaction occurs. All geomembranes had no water reach 100% hydrophobicity. highest­ tensile test value shown by 0,25 b/b% which about 21.235 MPa 16.01 before after soil burial four weeks, respectively. Perhaps might be due between low concentrations lower polarity is nonpolar better compatibility than
