Repurposing of Waste High-Density Polyethylene Plastic as Floor Tiles
摘要
This paper focused on the production of plastic floor tiles made from high-density polyethylene (HDPE) plastic wastes that have standard compressive property based on the standard values of ASTM D695, also known as the Standard Test Method for Compressive Properties of Rigid Plastics. This is relevant in introducing a new method to repurpose plastic wastes and transform them into new construction materials such as floor tiles. In this study, a Research and Development design was employed where five (5) phases were executed which were collecting, cleaning and sorting, melting, testing, and evaluating. Nine (9) trials of tile production were performed to measure the amount of HDPE plastic wastes and sand needed to produce a single 4 × 4 × 0.5 inches plastic waste tile, which was found out to be a total of 130 grams. After conducting the compressive test, the mean compressive strengths of the tile groups, Pure HDPE, 90% HDPE; 10% Sand, and 80% HDPE; 20% Sand, were discovered to be 2655.4 psi, 2852.2 psi, and 2922.6 psi respectively. In addition, their compressive moduli of elasticity were 72.75 ksi, 80.34 ksi, and 114.61 ksi, respectively. The data showed that the 80% HDPE; 20% Sand group exhibited the greatest compressive property. Testing the significant difference of the groups through One-way ANOVA and Tukey HSD showed that only between the groups of Pure HDPE and 80% HDPE; 20% Sand did the significant difference occur with a significant value of 0.009. These were the conclusive data indicating that the produced plastic waste tiles met the minimum requirements of ASTM D695 and were suitable for flooring use.
