AB  - Adapting sustainable construction, which involves responsible consumption of 
      natural resources and reducing carbon emissions, could be a unified action to 
      address the intensifying effects of global warming and the increasing rate of 
      waste pollution worldwide. Aiming to lessen the emission from the construction 
      and waste sector and eliminate plastics in the open environment, a foam fly ash 
      geopolymer with recycled High-Density Polyethylene (HDPE) plastics was developed 
      in this study. The effects of the increasing percentages of HDPE on the 
      thermo-physicomechanical properties of foam geopolymer were investigated. The 
      samples' measured density, compressive strength, and thermal conductivity at 
      0.25% and 0.50% HDPE content was 1593.96 kg/m(3) and 1479.06 kg/m(3), 12.67 MPa 
      and 7.89 MPa, and 0.352 W/mK and 0.373 W/mK, respectively. Obtained results are 
      comparable to structural and insulating lightweight concretes with a density of 
      less than 1600 kg/m(3), compressive strength of greater than 3.5 MPa, and thermal 
      conductivity of less than 0.75 W/mK. Thus, this research concluded that the 
      developed foam geopolymers from recycled HDPE plastics could be a sustainable 
      alternative material and be optimized in the building and construction industry.
