“…Design of experiments is defined as a sequence of data collection to achieve a specific goal of the experimentalist. Among the best known methods, factorial design is the most appropriate when you want to study the effects of two or more variables of influence, making all possible combinations of levels of each variable (Cunico et al, 2019;Silva et al, 2008;Tunik et al, 2008). The statistical technique that evaluates whether the means of two or more populations are equal is called Analysis of Variance.…”

“…Due to the large amounts of plastic waste and the difficulty in their deposit, many researchers have focused on different applications of recycled plastic waste, including wood-plastic composites, new polymers, and 3D printing [5][6][7]. However, a lot of research seems to be directed towards the use of recycled plastic in construction applications and especially in concrete [8,9].…”

End-of-life plastics are an increasing environmental problem that needs to be addressed. Within the scope of utilizing secondary and recycled materials as aggregate in the construction industry, recycled XLPE and PET plastics were used as aggregates in cement-based mortars. The recycled plastics were reduced to fine aggregate granulometry and were used to partially replace natural sand in mortars. The replacement rates tested were 20% and 30% for XLPE, 30%, 50%, and 80% for PET, while a test mortar with 90% combined replacement with XLPE and PET was also tested. The workability of the mortars reduced with XLPE use and increased with PET use and the same pattern was observed regarding the porosity and water absorption of the hardened mortars. Compressive strength and density, on the other hand, reduced for both alternative aggregates, but recycled PET showed better performance overall and could be considered as an alternative for the production of lightweight mortars.

Fused filament fabrication (FFF) is one of the most popular 3D printing approaches among end‐users due to its lower cost, ease of operation, and wide range of material choices. However, the use of composite filament produced from recycled plastic and agriculture waste is still relatively uncommon. This research focuses on developing composite filament from corn husk fiber (CHF) and recycled single‐use polypropylene for FFF. In this work, neat recycled polypropylene (rPP) and rPP/CHF composites were extruded into filament for FFF printing. It was observed that increasing the CHF content would reduce the print quality of the parts, as visible air gaps and voids were found on the printed surface and within the layers. Nevertheless, these issues were able to be overcome by adjusting the printing temperature and increasing the extrusion percentage during the printing process. The melt flow index results indicate that a higher CHF content would reduce the melt flow of the extruded rPP/CHF composite during printing, potentially affecting the quality of the printed parts. On the other hand, increasing the temperature enhanced the melt flow of the composite, which was beneficial for the printing process. When a small amount of CHF was added to the rPP, the printed part exhibited the highest tensile strength due to the reinforcing effect of the fibers. However, the tensile strength of printed parts using rPP/CHF composite filament decreased with higher CHF content. Additionally, higher CHF content resulted in printed composite parts that were more rigid and stiffer. It also reduced warpage on the printed specimens made with this composite, but it is important to note that warpage of the printed specimen is not directly correlated to crystallinity caused by nucleating effect of CHF. The rPP/CHF composite filament did exhibit earlier thermal degradation due to the addition of more CHF. However, this should not affect the printing process when temperature not beyond 230°C. This study highlights the potential of utilizing single‐use PP and fibers extracted from corn husk as feedstock for 3D printing. The findings expand the possibilities for recycling and employing agricultural waste in sustainable additive manufacturing processes.Highlights Utilizes single‐use PP and CHF in developing composite filaments, contributing to sustainability and reducing plastic waste. This research offers a sustainable approach by utilizing waste materials as feedstock for FFF‐based 3D printing, which able to reduce the environmental pollution caused by disposal of single‐use plastic and promotes recycling practices.
