Polyethylene terephthalate (PET) is a polyester resin produced by the condensation reaction between terephthalic acidand ethylene glycol. Since it has excellent engineering properties such as thermal stability, transparency, and strength,the consumption for packaging containers increases every year; in turn, waste PET increased. It is difficult to recyclePET due to the lack of facilities, which makes waste PET a source of environmental pollution. In this study, we analyzedthe engineering properties of waste PET to explore the possibility of using it as an alternative to concrete, the latter ofwhich produces carbon dioxide emissions and causes environmental damage by collecting natural aggregates. We foundthat the compressive strength of waste PET was 32.89MPa, tensile strength was 31.43 MPa, Izod impact strength was2.68 kJ/m2, and Rockwell hardness was 122.17. These results showed that the compressive strength was equivalent tothat of ordinary concrete, and the tensile strength and hardness were better. However, the impact strength was low. Also,waste PET showed a lack of resistance to dynamic loads acting suddenly in various directions. However, in the staticload condition such as the weight of soil, we found that the cross-section is simple such as pile foundation, culvert, block,and waste pipe, and waste PET can be used as construction materials manufactured using concrete.
