Plastic waste and energy consumption are the main environmental crises raised by global awareness in the last years. One the most efficient ways to reduce a building’s energy demand is the use of building materials with high thermal resistance. Plastics have low thermal conductivity, hence developing building materials based on the use of recycled plastic may enhance the building’s thermal performance and will save our environment from the harmful impact of plastic pollution. The aim of the present research is to identify the potential of using recycled plastic in building materials with the purpose of developing eco-friendly lightweight mortar with enhanced thermal properties. An experimental study is carried out to investigate the effect of partially substituting mortar’s fine aggregate with recycled high-density polyethylene (HDPE) on the thermomechanical performance. Different substitution ratios (5%, 10 % and 20%) were tested to determine the suitable plastic content in the composite. The results showed the highest compressive strength results for 5 % replacement, the lowest density and thermal conductivity for the 20% replacement. This study determines that merging plastic waste in building materials is a valuable energy-efficient practice.
