Abstract

3D printing technology is rapidly developing in the manufacturing industry in producing complex and easily adjustable three-dimensional objects using the help of controls from computers. Behind its advantages, the 3D printing process requires filaments from virgin polymers which generally have a high price and adversely affect the environment. Post-consumer polymer recycling is a substitute material solution from virgin polymers and is environmentally friendly so as to support the realization of a circular economy. Studies on 3D printing filaments from post-consumer polymers have been discussed in this article, especially for filaments derived from acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and polyethylene terephthalate (PET). In addition, this article also reviews the sources of recycled raw materials, difficulties during the process, mechanical properties, thermal properties and efforts to improve the quality of 3D printing products. The results show that recycling post-consumer polymers for 3D printing filament applications is a promising approach to reducing the environmental impact of 3D printing while still retaining the mechanical properties and printability of filaments. This article provides insight into several studies that address the development of 3D printing using post-consumer polymer materials.

Abstract

Multilayer plastic waste, particularly from the bottled water industry, represents a persistent challenge in current plastic waste management strategies. Simultaneously, oil palm empty fruit bunch (OPEFB) waste, though often discarded, possesses significant potential for sustainable material development. This study explores the utilization of both waste streams as raw materials for biocomposite fabrication, thereby addressing environmental concerns while reducing dependence on virgin polymer resources. The multilayer lid film waste (comprising PET, LDPE, and LLDPE) and OPEFB fibers were processed through crushing, sieving, and extrusion to form pellets with varying OPEFB fiber loadings (30%, 50%, and 70% by weight). The resulting biocomposite was characterized using FTIR, XRD, SEM, density measurements, and tensile testing. The biocomposite containing 70% OPEFB exhibited the slowest degradation but also the lowest crystallinity (10.84%). In contrast, the 30% OPEFB composite showed the highest tensile strength (16.86 MPa) and elongation at break (3.23 MPa). SEM analysis revealed that a higher fiber content increased the porosity within the composite matrix. These findings demonstrate the potential of combining multilayer plastic and OPEFB waste for biocomposite applications, contributing to both material innovation and environmental sustainability.
