Abstract

Plastic waste generation has become a pressing environmental challenge due to the widespread use of plastic materials, which offer versatility, durability, and cost-effectiveness. This study investigates the feasibility of fabricating recycled high-density polyethene (HDPE) planks for furniture applications by evaluating their physio-mechanical properties. The research addresses the urgent need for effective waste management strategies, mainly plastic waste recycling, to mitigate environmental sustainability concerns. The study analyses the recycled HDPE planks’ tensile strength, flexural strength, and water absorption characteristics. The results indicate that the planks exhibit an average tensile strength of 14.36 ± 1.24 MPa and flexural strength of 46.57 ± 3.11 MPa, highlighting their suitability for furniture applications. Moreover, less than 0.01% water absorption rate confirms their capability to withstand outdoor conditions. A survey was conducted with 70 participants to gather feedback on the furniture product and gauge user perception. Most users expressed high satisfaction and appreciation for this sustainable initiative, recognizing the importance of promoting daily sustainability practices. This positive user feedback reinforces the significance of waste management practices and encourages the broader adoption of sustainable engineering solutions. This study offers compelling evidence supporting the utilization of recycled HDPE planks in furniture applications. It underscores the importance of effective waste management in addressing environmental concerns associated with plastic waste. The study’s findings highlight the feasibility of implementing sustainable engineering solutions to catalyze broader recycling practices adoption and promote a sustainable lifestyle.
