“…Extruded rPETs are commonly in the shape of filaments that are about five times finer than human hair. [ 31 ] Moreover, these filaments will be usually processed in hot metal rollers to be stretched into the form of recycled polyester‐stapled fibers. These drawn fibers can be utilized for various applications such as automotive and construction.…”

With increasing usage of polyethylene terephthalate (PET) wastes polluting the oceans and environment, the recycling of PET wastes has become a crucial issue to be overcome. In this article, a review of the different technologies that have been developed to recycle PET wastes and common routes for recycled PET (rPET) is presented. The impacts of varied recycling technologies on the properties of rPET are also discussed herein. The review also focuses on the recovered products by each of the technology and their uses that have been reincorporated into new applications for example, from plastic bottle wastes to 3D scaffolds for biomedical application. Different recycling technologies such as reactive extrusion, chemical recycling and dissolution/precipitation exhibit specific properties due to the influence of the different concepts from one technology to another. A new trend called electrospinning of rPET to produce nanofibers has also garnered attention to be used for different applications. This article will first introduce the recycling technologies concept, and then the properties of the recovered product will be discussed and finally, we will focus on the applications of rPET produced from each of the technologies in various fields such as construction, textile, filtration, and biomedical applications.

“…Semicrystalline PET is characterized by its high thermal, chemical and mechanical stability, clarity, durability, and flexibility while the amorphous PET possesses the same properties but with a less hardness and a higher flexibility. These desirable characteristics along with the relatively low cost have enabled widespread use of PET especially in food packaging and drink bottles 230–233 . As can be seen in Table 1, there are several studies on the use of PET substrates for CVD, particularly to enhance oxygen and water vapor barrier properties.…”

Advanced materials are among the prime drivers for technological revolutions and transformation in quality of lives. Over time, several modification techniques have emerged enabling development of novel materials with extraordinary features. The present review aims to introduce various promising chemical and physical surface modification techniques instrumental for tailoring the characteristics of thin films and membranes. Meticulous discussions are provided over chemical vapor deposition (CVD) techniques evolved for addressing the demands for materials with desired functionalities. Also, essential criteria for the selection of substrates, modifying and precursor materials for an effective CVD modification are elaborated. Investigations are extended to unraveling the role of various process parameters on the quality and properties of deposition. Special attention is paid to the significance and performance of CVD‐based membranes and thin films for industrial applications ranging from desalination and water treatment to energy and environment, biomedical and life science as well as packaging. The goal has been to establish a scientific platform for a timely tracking of the prevailing trends in exploitation of CVD techniques and highlighting the unexplored opportunities. This also helps in identification of the scientific and technical gaps and setting directions for further progress in the fields of thin films and membranes.

“…Even if the applications of recycled PET (rPET) can vary depending on the countries, today rPET is mainly used for fibres and plastic bottle production as presented in Figure 14 [246,254]. However, rPET can also be found in electrical and lighting components, housewares, sports equipment, automotive parts [256], and in bitumen roads and pavement [242]. rPET presents some advantages in the construction industry, such as raising the ductility of concrete or reducing the weight of aggregates [242,257].…”

“…Subjecting PET, in particular multi-layered PET packaging, to several mechanical reprocessing cycles produces lower quality rPET products because of the degradation of PET during the re-melting process [256,282,289,290]. The breakdown of the backbone chain causes a decrease in the molecular weight and intrinsic viscosity (IV) with a rise of the end groups' (carboxyl and hydroxyl) number [282,289,291].…”

“…The use of rPET in fabrics has been highlighted by the sports industry, for example, the US men's basketball team uniforms have been made from r-PET bottles [256]. The development of rPOs and rPET microfibril composites which can be further reinforced with GF or natural fibres has led to the possibility of rPET being used in higher performance applications such as scaffolding, railroad ties, or car bumpers [256]. The drawback of this use is the loss of recyclability caused by the introduction of fibres in the blends.…”

Plastics are versatile materials used in a variety of sectors that have seen a rapid increase in their global production. Millions of tonnes of plastic wastes are generated each year, which puts pressure on plastic waste management methods to prevent their accumulation within the environment. Recycling is an attractive disposal method and aids the initiative of a circular plastic economy, but recycling still has challenges to overcome. This review starts with an overview of the current European recycling strategies for solid plastic waste and the challenges faced. Emphasis lies on the recycling of polyolefins (POs) and polyethylene terephthalate (PET) which are found in plastic packaging, as packaging contributes a signification proportion to solid plastic wastes. Both sections, the recycling of POs and PET, discuss the sources of wastes, chemical and mechanical recycling, effects of recycling on the material properties, strategies to improve the performance of recycled POs and PET, and finally the applications of recycled POs and PET. The review concludes with a discussion of the future potential and opportunities of recycled POs and PET.
