The Development of Composite Materials for Architectural Work Using Oil Palm Frond and Plastic Fishing Net Waste

Abstract

In southern Thailand, the accumulation of oil palm fronds and plastic waste, particularly discarded fishing nets from local fishery and farming communities, poses significant environmental challenges due to limited large-scale recycling options. This study aims to develop innovative composite materials for architectural applications by utilizing oil palm fronds and plastic fishing net waste, thereby reducing environmental pollution and promoting sustainable waste management. The research employs an experimental approach to fabricate composite panels through a systematic formation process, followed by comprehensive testing of their physical and mechanical properties. Physical properties evaluated include density, thickness swelling, and water absorption, while mechanical properties encompass modulus of rupture (MOR), modulus of elasticity (MOE), and internal bonding strength (IB). The results demonstrate that incorporating plastic fishing net waste significantly enhances the composite’s density, flexural strength (MOR), modulus of elasticity (MOE), and tensile strength perpendicular to the surface. Specifically, these properties exhibit a positive correlation with the proportion of plastic fishing net waste in the composite mix, with optimal performance observed at higher plastic ratios. Conversely, thickness swelling decreases as the plastic content increases, indicating improved dimensional stability. All tested composite panel specimens meet or exceed the requirements of the Thai Industrial Standard (TIS) 876-2565 (2022) for particleboards, confirming their suitability for interior architectural applications, such as wall panels and ceiling materials. This research not only provides a sustainable solution to manage agricultural and plastic waste in southern Thailand but also contributes to the development of eco-friendly, high-performance materials for the construction industry, supporting circular economy principles and environmental conservation.
