In today’s world, increasing problems related to plastics is a concern for every living species, so there is a need to find a solution to this problem. Hence, working on this issue, the main aim of this study is to tackle the plastic waste generated in abundance throughout the world. To gain success in this, a systematic method is employed which makes use of plastic extrude for reutilizing waste plastic into suitable construction materials. Using only plastic waste or adding some other ingredients such as powder, fly ash, etc plastic is converted into useful construction materials such as pavers, railway sleepers, building blocks, etc. A number of trials with different combinations were conducted to efficiently convert waste plastic into bricks. It was noted that maximum compressive load which the LDPE plastic beads brick could sustain was 13.69 N/mm2. This was followed by LDPE fly ash composite brick with a strength of 11.48 – 10.42 N/mm2, which is higher than the compressive strength of the conventional bricks available in the market made up of clay which had a compressive strength of 3-5 N/mm2.
