“…There are existing and emerging approaches for recycling polymer waste which may contain thermoplastics or crosslinked polymers. The categories of recycling technologies that include primary, secondary (mechanical), tertiary (chemical), and quaternary approaches may be summarized as follows [17,31,44,[56][57][58][59][60][61][62][63][64][65][66]:…”

“…Chemical recycling, in other words feedstock recycling, breaks down the synthetic fibers for repolymerization and yields the monomers of the polymers (or partially depolymerises to oligomers) by performing processes such as hydrolysis, pyrolysis, gasification, condensation, glycolysis, hydrocracking, dissolution etc. [57,59] For chemical recycling the synthetic fibers are chopped, pelletized, depolymerised by chemicals and repolymerised for fiber formation. An overview of the process is shown in Figure 4.…”

“…Presence of additives and chemicals used during polymerization might also complicate the processing and affect the purity and quality of the monomers obtained after chemical recycling. [35,58,59,65] Existing chemical processes for recycling polyester are expected to increase and new chemical recycling approaches for polyester in laboratory scale are expected to be developed until 2030. Chemical recycling of cotton and other cellulose based fibers are expected to be developed in full scale by 2030.…”

Today, World economy is only 8.6% circular, which creates a huge potential in materials reuse. To close the Emission Gap by 2032, this percentage needs to be doubled. The circular economy ensures that with less virgin material input and fewer emissions. With the help of effective recycling technologies, virgin material use can be decreased and especially petroleum based materials impact can fall within planetary boundaries. This book chapter analyzes different chemical and biological recycling technologies, their advantages and challenges in denim production. Moreover, Life Cycle Assessment (LCA) analysis will be used to evaluate the environmental impact of recycled polymeric materials usage in denim fabrics. Finally, it concludes by challenges and the future of chemically recycled materials in denim production and opportunities to evaluate waste as a raw material to design circular systems.

Circular economy is still an imaginary field. In this manuscript, mild steel material is used to evaluate the coefficient of friction (COF) of cotton fabric. COF is evaluated to facilitate circular economy of textile industries. Scanning electron microscope (SEM), optical profilometer, mechanical profilometer and tribometer were used for AISI 52100 steel balls and cotton textile waste. The fabric surface was found distorted and damaged due to joggling, bobs, jerks, and pills surface defects. These defects produced due to physical and chemical treatments. The average coating surface roughness parameters were Rmax (0.35 µm), Rz (0.50 µm), and Rp (0.45). The dynamic coefficient of friction (COF) values was found 0.21 to 0.12 in warp and 0.17 to 0.10 in weft directions. The tensile strength and hardness values of mild steel 2600 MPa and 65 on HRC, respectively proved that metallic surface is smooth and soft. The smaller COF values and soft metallic surface produced low grip and cutting resistance due to damaged and distorted textile wastes. Based on COF values, deformation, wear and morphology evaluations, the mild steel machinery parts could be used operationally for recycling of textile wastes. for surface alterations of textile machinery parts. Furthermore, damaged, and distorted post-consumer textile wastes required hard, high strength and well finished machinery parts surfaces for its recycling.
