The purpose of the study was to determine the effect of plastic waste on the compressive strength, water absorption, and temperature resistance of lightweight bricks for green architecture. This study is included in quantitative research using the Experimental method. The variations of plastic that will be used are PETE, HDPE, and LDPE plastic types, each of which is 10%, 20%, and 30% of the weight of cement. The test object made is a cylindrical lightweight brick with a diameter of 10.8 cm and a height of 5 cm. The mixture of lightweight bricks made includes cement, sand, foam agent, and water. After obtaining the compressive strength, water absorption, and temperature resistance values of each test object, it is then compared with the benchmark object, namely lightweight bricks without a plastic mixture to see if there is an effect of the plastic mixture. There is an effect of the plastic mixture on the compressive strength seen from the increase in compressive strength in lightweight bricks mixed with 10% PETE plastic. There is an effect of the plastic mixture on the water absorption seen from the increase in water absorption in lightweight bricks mixed with 10% PETE plastic. There is an effect of plastic mixture on temperature resistance as seen from the increase in compressive strength of lightweight bricks mixed with 30% HDPE plastic. It can be concluded that plastic can affect the quality of lightweight bricks and is suitable for highly recyclable materials that can be utilized in green architecture. © 2026, Trans Tech Publications Ltd.
