N2 - Natural aggregate consumption for producing concrete depletes the natural aggregate, necessitating the development of alternative materials that do not cause a burden on natural resources. Electronic plastic waste (EPW) like digital video discs (DVDs) and compact discs (CDs) are becoming an extreme burden to the environment due to the high quantities generated, which pose serious harm to both the environment and its inhabitants. This study presents the concept of recycling EPW and converting it into construction materials with high specifications. Using 100% EPW in place of sand and 4% unsaturated polyester resin with 20% high reactivity attapulgite (HRA) as a filler, the study generated lightweight polyester concrete (LWPC). The HRA was used after calcination at three temperatures (300, 600 and 900 °C), and for comparison, without calcination, various concentrations of the concrete components were used to produce LWPC using EPW with the optimum polyester resin percentage and HRA burning temperature. The study assessed the physical and mechanical properties of 24 mixtures of LWPC and showed the possibility of producing a novel type of high-strength, sustainable, LWPC with high properties (rapid-set, followability and ductility). The results showed that reducing the concrete’s density to below 1385 kg/m
3 and, when optimal quantities of polyester resin, EPW, and HRA were used, enhanced the workability, flowability, and mechanical properties of fresh and hardened concrete.
