“…[158] According to Gaspar and co-workers, [166] agriculture wastes can be classified as stalks, husks, and grain of crops or as raw materials in the form of fibers from crop residues. Due to the natural and organic characteristic, low cost, easy availability, and renewability, a huge type of crop residues, for example, sugarcane, [167,168] cork, [169] cassava cortex, [170] bamboo fibers, [171] sunflower husk, hazelnut shell, [172] maize cob, [173] and walnut shell [174] have been used in polymer composites. Masłowski and coworkers [175] have incorporated cereal straw in vulcanized rubber.…”

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.

“…Few attempts were made for the UPR composites using glass fiber fillers. Natural fillers such as wood flour or sawdust, maize cob, peanut shell, jute, bamboo, ramie and kenaf fiber are more and more popular and are used today [25][26][27][28][29][30][31][32][33]. For the VER, incorporation of kenaf, coconut or date palm seed are reported [34][35][36][37].…”

This study compares the degradation process of unsaturated polyester resin (UPR) and vinyl ester resin (VER) and their biocomposites with kraft lignin. In order to study their degradation, accelerated aging, immersion in different solvents, microwave radiation and high temperature were applied. The results show that, depending on the conditions, the degradation assumes a different course. The VER resin is more chemically resistant than the UPR resin. In the case of the composites immersed in an aggressive solvent (acetone), it can be observed that the polymer matrix is degraded, whereas in water only a small increase of weight takes place. Immersion in NaOH initiates the degradation process consisting in the hydrolysis of ester bonds, which are especially observed for pure resins. Under the influence of UV radiation and microwaves, the resins are additionally cross-linked. Thermogravimetric analysis shows that in the case of composites heated to 1000 °C, a residual mass remains, which is carbonized with lignin. In turn, composites treated with microwaves lost weight.

“…Recycling also helps in greening our infrastructures by conserving natural resources, making our infrastructures more durable due to high-performance mixtures, reducing greenhouse gas emissions and air pollution and groundwater contamination [13]. Many researchers researched composite materials reinforced with different textile materials such as textile microfibers waste [14], cotton fibers waste [15], polyester fiber waste [16], woven bamboo fiber [17], rice husk, wheat husk, wood fibers and textile waste fibers [18], Maize Cob and Jute Fiber [19], polyester-cotton fabric [12], cotton, jute, and glass fabric (Masood et al 2018), banana woven fabric 8, paper/jute fabric [20], low-density polyethylene (LDPE) [21], and biodegradable textile waste [22].…”

In recent years, the garment and textile industries generate millions of tons of textile waste every year around the world. Textile wastes are one of the disposed of materials and the sum of disposed of material squander materials expanded from year to year. For this reason, regenerating and utilizing the textile waste item as resources and decreasing environmental pollution may be an extraordinary opportunity. This research is aimed at manufacturing unsaturated polyester composite reinforced with 100% cotton fabric waste for ceiling board application using a manual mixing process followed by the compression molding method. The statistical results showed that mechanical properties of the produced composite samples such as tensile, compressive, flexural, and impact strength are affected by fiber mixed ratio and matrix loading at α = 0.05 . The composite ceiling reinforced with 33 weight % cotton fabric waste and a matrix of 67 weight % unsaturated polyester had a maximum tensile strength of 198 MPa, the flexural strength of 30.1 MPa, and compressive strength of 1105.3 MPa. On the contrary, the false ceiling board made from 10% cotton fabric waste and matrix of 90% unsaturated polyester had a lower tensile strength of 112.6 MPa, flexural strength of 21.5 MPa, and compressive strength of 867.5 MPa. Generally, the manufactured composites’ mechanical behaviors were comparable to existing commercial ceiling boards and the output of this research work can protect the environmental pollution by reducing textile waste disposed to landfills.
