Abstract

This research aimed to 1) design and develop a semi-automation foam grinding machine integrated with molding for waterproof floor sheets from agricultural waste, and 2) test the mechanical properties of the produced tiles. The study was conducted in the form of developmental research, focusing on repurposing household foam waste, such as food containers, through engineering processes that support the principles of a circular economy. The results revealed that the developed prototype consisted of a foam grinding unit, a mixing chamber, and a molding system, all operated semi-automatically via an LCD control panel. The machine was compact, user-friendly, and suitable for household or community use. The produced floor tiles demonstrated favorable mechanical properties. They exhibited a low water absorption rate of 2.35%, a high compressive strength of 178.6 kilonewtons per square meter (kN/m²), and a Shore D surface hardness of 72, indicating their suitability for outdoor use in areas such as gardens, walkways, and community spaces. Furthermore, the production cost per unit was low, with a projected payback period of approximately one year under continuous production. The findings suggest that recycling waste materials can be transformed into high-quality, functional products that contribute to sustainable waste management. Further enhancement of the prototype to reach higher technology readiness levels, along with technology transfer to community occupational groups, is encouraged to foster local income generation and long-term sustainability.
