Plastic waste is identified as non-biodegradable material that is harmful to the environment. PET is one of the most well-known types of plastic used for food packaging that usually plastic waste be found in huge amounts. This paper takes advantage of PET plastic waste from the water drinking cup to be blended with fly ash to produce a lightweight aggregate called FAPET. All the properties of FAPET were significantly better than pumice as the control sample during the experiment such as water absorption, compressive strength and abrasion value of 0.5%, 17.4 MPa and 28.55% respectively. FAPET was derived from the double blending process of PET with fly ash with the composition of PET and fly ash was 1:3. The experiment conducted was partial until the full replacement of pumice as a lightweight aggregate with FAPET to establish waste-based lightweight concrete. Modulus of elasticity and compressive strength resulted from 100% replacement using FAPET were 31,706 MPa and 23,64 MPa that equalled to normal concrete strength. The utilization of FAPET is concluded to be successful as an alternative lightweight aggregate for structural use of lightweight concrete.
