This study consists of proposing a method of recycling polystyrene and glass bottle waste, by making construction materials. With a view to valorization its waste, this study was carried out and consisted of the development of materials based on expanded polystyrene (EPS) and bottle shards. The samples were developed with PSE rate varying from 20% to 85% with an increment of 5, followed by tests to determine their physical properties (density and absorption) and their mechanical properties (wear strength and three-point flexural strength). The results obtained show that the density of the materials decreases from 2.11 g⁄cm³ to 1.06 g⁄cm³ with an increase in the PSE rate. Likewise, absorption decreases from 4.45 to 0.33 with an increase in the PSE rate. Wear resistance also drops from 1.36 g⁄cm² to 0.0 g⁄cm² when going from 20 to 85% EPS. At last, the three-point flexural strength increases from 9.35 MPa to 23.19 MPa when going from 20 to 85% EPS. The use of EPS as a binder in materials gives it encouraging physical and mechanical properties. EPS and bottle shards waste considered as a new raw material resource in the manufacture of materials therefore constitutes a valorization way for this packaging waste.
