Purpose: This study aims to examine the properties of polypropylene (PP) composites filled with household waste tea (camellia sinensis) (HWT) to development of their mechanical properties and also to gain the economic value of HWT. Design/methodology/approach: HWT was grinded using a disk mill in the finely powder form. Prepared finely tea powders were characterized compositional and morphologically by using Fourier transform infrared spectroscopy, X-Ray diffractometer and scanning electron microscope. PP composites were prepared at different proportions of HWT ranging from 0 wt% to 40 wt% with two particle sizes (<30 µm and <60 µm) by high-volume energy mixer so as to evaluate the effect of the HWT filler on mechanical properties. Findings: The mechanical properties of composites were evaluated through modulus of elasticity, ultimate tensile strength and flexural strength in terms of filler particle size and filler contents. The results showed that the modulus of elasticity of composites increased as a function of additional HWT particles and the highest value was observed which was containing 40 wt% filler contents. Research limitations/implications: Clearly, the maximum flexural and tensile strength of HWT particles filled composites were observed for 10 wt% HWT loading into PP composite increased when compared to other filler contents (20-40 wt%). Practical implications: For potential applications in the plastics industry, such as outdoor deck floors, cladding and siding, indoor furniture etc., it is desirable to form polymer composite systems by combining phases with polymer, so as to reduce expenses of materials, to have strength and, at the same time to be biodegradable. Originality/value: Despite HWT was chemically untreated, the mechanical properties of composites increased it would appear that it can be a renewable alternative material for manufacturing of PP matrix composites.

“…Regarding the ambitious goals set by the European community for a bioeconomy, which include the decarbonization of the economy through an 80-95% decrease of CO 2 emissions by 2050 (Scarlat et al 2015), ViShs present a valuable resource for implementing decarbonizing recovery strategies. These strategies can be achieved in a biorefinery context, where cascading treatments of ViSh are investigated to produce value-added products, including the production of lignocellulosic fillers for biocomposite applications (Kilinc et al 2016;David et al 2019David et al , 2020a. Lignocellulosic fillers from agricultural residues present the advantages that, in addition to their fully biodegradability in natural conditions, they have a lower density than conventional inorganic fillers and are highly available at a low price, with no competition from the food sector (Mohanty et al 2001).…”

Purpose The objective of the present study was to better understand the potential environmental benefit of using vine shoots (ViShs), an agricultural residue, as filler in composite materials. For that purpose, a comparative life cycle assessment (LCA) of a rigid tray made of virgin poly(3-hydroxybutyrate-co-3-hydroxyvalerate) PHBV, polylactic acid (PLA) or polypropylene (PP), and increasing content of ViSh particles was performed. The contribution of each processing step in the life cycle on the different environmental impacts was identified and discussed. Furthermore, the balance between the environmental and the economic benefits of composite trays was discussed. Methods This work presents a cradle-to-grave LCA of composite rigid trays. Once collected in vineyards, ViShs were dried and ground using dry fractionation processes, then mixed with a polymer matrix by melt extrusion to produce compounds that were finally injected to obtain rigid trays for food packaging. The density of each component was taken into account in order to compare trays with the same volume. The maximum filler content was set to 30 vol% according to recommendations from literature and industrial data. The ReCiPe 2016 Midpoint Hierarchist (H) methodology was used for the assessment using the cutoff system model. Results and discussion This study showed that bioplastics are currently less eco-friendly than PP. This is in part due to the fact that LCA does not account for, in existing tools, effects of microplastic accumulation and that bioplastic technologies are still under development with low tonnage. This study also demonstrated the environmental interest of the development of biocomposites by the incorporation of ViSh particles. The minimal filler content of interest depended on the matrices and the impact categories. Concerning global warming, composite trays had less impact than virgin plastic trays from 5 vol% for PHBV or PLA and from 20 vol% for PP. Concerning PHBV, the only biodegradable polymer in natural conditions in this study, the price and the impact on global warming are reduced by 25% and 20% respectively when 30 vol% of ViSh are added. Conclusion The benefit of using vine shoots in composite materials from an environmental and economical point of view was demonstrated. As a recommendation, the polymer production step, which constitutes the most important impact, should be optimized and the maximum filler content in composite materials should be increased.
