“…10 Use of polymer composite materials after recycling in various applications such as protective shielding materials in radiation facilities, aerospace engineering, industry, electromagnetic, and nuclear shielding thermoplastic composites (CFRTPCs), high material recovery rates were observed for the polylactic acid matrix (73%) and carbon fiber (100%) (Tian et al 2016). Recycled polyethylene terephthalate and polyacrylonitrile (RPET/PAN) composites showed a flexural strength increment and drying shrinkage (Chinchillas-Chinchillas et al 2019). The chemical oxygen demand (COD) was reduced, and the mineralization percentage in recycled polymeric materials include cotton, cotton lycra, polyamide, paper, polyethylene terephthalate, polypropylene, and polyurethane (El-Mekkawi et al 2019).…”

The rising use of radioactive elements is increasing radioactive pollution and calling for advanced materials to protect individuals. For instance, polymers are promising due to their mechanical, electrical, thermal, and multifunctional properties. Moreover, composites made of polymers and high atomic number fillers should allow to obtain material with low-weight, good flexibility, and good processability. Here we review the synthesis of polymer materials for radiation protection, with focus on the role of the nanofillers. We discuss the effectivness of polymeric materials for the absorption of fast neutrons. We also present the recycling of polymers into composites.

“…Second, plastics can be destroyed thermally. Finally, plastics can be discarded and even contained in a managed system [ 1 , 3 , 11 ]. However, regarding the reprocessing, using recycling material also has its challenges (e.g., unstable quality, impurities) since the pure polymer is mixed with additives to enhance the properties of the material [ 1 ].…”

“…Moreover, only the central part of the bottles was used. The reuse of waste as a source of raw material for making filter media is a sustainable and energy-friendly alternative since it favors the use of renewable energy sources and has been widely reported in the literature [ 8 , 12 , 13 , 14 , 15 ], as the manufacture of a functionalized magnetic fullerene (FMFN) nanocomposite associated with sustainable residues from PET bottles [ 16 ], and in civil construction, with recycled PET fibers being used to reinforce the mechanical properties of construction materials [ 11 , 17 , 18 , 19 ].…”

“…Nonwoven fabrics of PET could here play a momentous role in dust filtration because of their porous structure and low cost of manufacturing in combination with their unique mechanical properties such as high mechanical resistance [ 8 , 11 , 14 , 17 ]. This characteristic was a differential in this work since the high mechanical resistance of the developed fibers maintained the structural stability during the filtration tests.…”

A Sustainable Recycling Alternative: Electrospun PET-Membranes for Air Nanofiltration

et al. 2021

Currently, the inappropriate disposal of plastic materials, such as polyethylene terephthalate (PET) wastes, is a major environmental problem since it can cause serious damage to the environment and contribute to the proliferation of pathogenic microorganisms. To reduce this accumulation, PET-type bottles have been recycled, and also explored in other applications such as the development of membranes. Thus, this research aims to develop electrospun microfiber membranes from PET wastes and evaluate their use as an air filter media. The solution concentrations varied from 20 to 12% wt% of PET wastes, which caused a reduction of the average fiber diameter by 60% (from 3.25 µm to 1.27 µm). The electrospun filter membranes showed high mechanical resistance (4 MPa), adequate permeability (4.4 × 10−8 m2), high porosity (96%), and provided a high collection efficiency (about 100%) and low-pressure drop (212 Pa, whose face velocity was 4.8 cm/s) for the removal of viable aerosol nanoparticles. It can include bacteria, fungi, and also viruses, mainly SARS-CoV-2 (about 100 nm). Therefore, the developed electrospun membranes can be applied as indoor air filters, where extremely clean air is needed (e.g., hospitals, clean zones of pharmaceutical and food industry, aircraft, among others).

“…It is estimated that PET accounts for 18% of the world production (Leng et al 2018) and 7.4% of European plastics production (Europe 2018). A small amount of this PET waste is recycled, and the rest is left without recycling, regardless of their destructive effects (Chinchillas-Chinchillas et al 2020). Also, about 1 million plastic bottles are wasted every minute and are estimated to double in the next 20 years (Magnier et al 2019), and that many of these bottles are made of PET.…”

Recent Studies on Recycled PET Fibers: Production and Applications: a Review

et al. 2021

Increasing demand for non-biodegradable plastics undesirably leads to their accumulation and calls for an appropriate solution for this global crisis. Environmental impacts of PET waste have long been addressed; although some remedies have been proposed, their extensive use in the modern world use demands new studies and recycling techniques. It shows the inadequacy of previous solutions to eliminate this environmental problem. Therefore, researching this subject should not be considered an insignificant issue. Distinctively, this review article has a specific reliance on the use of recycled PET fibers in the production of high-consumption and value-added products that, in addition to considering environmental aspects, can also be attractive to the market. This article deals with recent studies in three product categories (concrete, nonwoven fabrics, yarns) made from recycled PET fibers and shows the high potential of PET fibers for the future industry.
