The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…UV aging resistance plays an important role in outdoor application of plant fiber and the reinforced composites. Nowadays, many approaches are developed to improve anti-UV aging performance of polymer composites, such as adding antioxidant, photo stabilizers, HALS (hindered amine light stabilizers) to consume the produced free radical, adding UVA (UV light absorber), [9][10][11][12] photo-blocker of pigments, dyeing [13][14][15][16] to capture light energy, surface coating or co-extrusion technology to provide a protection layer on composite surface, [17] adding ZnO, SiO 2 , TiO 2 , CaSO 4 , clay nanoparticles, carbon nanotubes and pecan (Carya illinoinensis) nutshell extract to improve the UV-resistant, [18][19][20][21][22] and so on. Most of these anti-aging approaches are of great help to improve the UV aging resistance of neat polymer and are well applied in artificial fiber reinforced composites.…”

Interfacial adhesion and the potential degradation are critical to service life and performances of plant fiber polymer composites. In this paper, the interfacial ultraviolet (UV) aging was studied by silane modification of hemp fiber on UV aging of the reinforced polypropylene (PP) composites. Three silane agents of 3-(Trimethoxysilyl)propyl methacrylate (MPS), N-[3-(Trimethoxysilyl)propyl]aniline (PAPS), and (3-Aminopropyl)-triethoxysilane (APS) were selected to obtain different interfacial adhesion. The composite degradation was characterized by surface observations, surface degradations, and tensile tests. The results show that functional group of silane agent has considerable effects on UV aging of the polymer composites. For APS, the composites have higher interfacial adhesion and exhibit slower surface whitening, cracking, degradation, and less mechanical properties deteriorations than others. After 8 weeks aging, its fracture stress and fracture strain decreased of 5.3% and 8.0%, respectively. Because aniline of PAPS is incompatible with PP matrix, the composites have a relative weak interfacial adhesion and shows faster surface whitening, cracking, and degradation. While aniline absorbs UV radiation strongly and may retard the interfacial degradation, thus its fracture stress hardly decreased after 8 weeks. However, ester group in MPS absorbs UV radiation and may get degraded leading to the decline of interfacial chain slips. Thus, fracture strains of the composites decrease greatest of 35.2%. It is concluded that interfacial adhesion and potential degradation are critical in UV aging. A "suitable" modifier improves not only initial mechanical properties but also the weathering resistance of plant fiber polymer composites.

“…Applications of eco-friendly, sustainable and degradable nanocomposites offer new technology and business opportunities for several sectors of the aerospace, automotive, construction, electronics, biotechnology and food packing industries. There is a tremendous interest for using bionanoparticles like nanocellulose to be applied in the new era of biocomposites (Gacitua et al 2005, Camargo et al 2009, Trache et al 2020and Chang et al 2020). Biocomposites refers to composite materials that contain one or more naturally derived content, which can be part of the reinforcement phase or matrix phase or both in a composite system.…”

“…Biocomposites refers to composite materials that contain one or more naturally derived content, which can be part of the reinforcement phase or matrix phase or both in a composite system. Various bionanocomposites have been produced using cellulose nanocrystals (CNCs) as nano llers and polymer matrixes from natural and renewable resources (Trache et al 2020 andChang et al 2020). Joseph et al (2020) gives a brief idea about the research and development pertaining to cellulose nanocomposites, characteristics and their biomedical applications.…”

The nanocellulose and its nanocomposites have significant importance in the most economic sectors of applications. This research involves the synthesis of nanocellulose from Albizia lebbeck wood sawdust. Quantitative evaluations of chemical components present in the sawdust of a native hardwood species Albizia lebbeck were determined by chemical analysis method. The results revealed that the approximate amount of hot water extractives, 96% ethanol extractives, alpha-cellulose, hollocellulose, hemicellulose, lignin and ash content were 6.9%, 7.31%, 40.72%, 65.10%, 24.38%, 25.67%, and 1.10% respectively. Nanocellulose was synthesized from the extracted alpha-cellulose by acid hydrolysis method. Fourier-transform infrared spectroscopy (FTIR) characterizations have been done for Albizia lebbeck sawdust, extracted alpha-cellulose and synthesized nanocellulose respectively. The average diameter of synthesized nanocellulose was found 155.6 nm by particle size analyzer. Nanocellulose with different weight percentages (2%, 4%, 6%, 8% and 10%) were reinforced with poly(vinyl chloride) (PVC) to prepare nanocomposites by solution casting method. The thermal stability of pure PVC, nanocellulose and 2wt% nanocellulose–PVC nanocomposite was investigated and the result revealed that 2 wt% nanocellulose reinforced PVC nanocomposites is thermally more stable than the nanocellulose and pure PVC. The tensile properties of all nanocomposites were counducted by universal testing machine (UTM) and the highest tensile strength was obtained for 2 wt% nanocellulose reinforced PVC nanocomposites. The scanning electron microscope (SEM) images of 2 wt% nanocellulose reinforced PVC nanocomposites also exhibited the uniformly dispersion of nanocelulose in nanocomposite.
