Traditional brick manufacturing contributes heavily to carbon emissions, while non-recyclable high density polythylene (HDPE) plastics and agricultural oil palm waste continue to pollute the environment. This project introduces Bio-Crete, an innovative eco-friendly brick designed to tackle both waste crises. Utilizing a Low-Heat Fusion process, shredded HDPE waste was melted to act as a binder matrix and reinforced with processed palm fibers to enhance strength, completely eliminating the need for cement and water. Standardized prototypes were fabricated and subjected to compressive strength and water absorption testing. Laboratory analysis revealed that Bio-Crete exhibits higher compressive strength, lower water absorption, and a significantly lighter weight compared to conventional clay bricks and commercial concrete. Additionally, sourcing zero-cost raw materials ensures highly competitive production economics. Ultimately, this project proves that Bio-Crete is a viable, scalable alternative for the construction industry, offering a green blueprint for future sustainable building standards.
