PET Bottle Recycling for Sustainable Textiles

Abstract

Polyethylene terephthalate (PET), as the most favorable packaging material, is owing to its transparent color, lightweight, strength, food safe, inexpensive price, fully recyclability, etc. In addition to all these advantages, PET as a waste material takes up considerable space in nature and needs to be recycled for the disposal of these wastes. In this regard, recycling enables conserving raw materials, reducing energy use in order to produce virgin PET, and reducing greenhouse gas emissions. Today, PET is the most widely recycled plastic in the world. Eco-friendly products obtained by recycling of PET are mainly used as textile fibers. In addition, both brands and consumers are seen to be enthusiastic in order to minimize the environmental effects of PET wastes. This study is concerned with the use of textile fiber from recycled PET (r-PET) bottles to produce a cotton blended ring and compact yarns. Undoubtedly, the study also includes comparison of cotton blended virgin polyester fiber (v-PET) with r-PET fiber to determine the advantages and disadvantages of r-PET fiber. The reason for choosing cotton fiber is the most preferred fiber blending with PET commercially.

Characterisation and composition identification of waste-derived fuels obtained from municipal solid waste using thermogravimetry: A review

“…The presence of textiles and beverage bottles are the reasons that PET is one of the prevalent fossil-based polymers in SRF/RDF (toughness, high resistance to most solvents, and clear and optically smooth surfaces; Villanueva and Eder, 2014 ) – not all of them are collected for recycling and therefore, may de facto and for now still constitute part of SRF/RDF. Specifically, polyester fibres from PET constitute the most widely used synthetic fibre in the textile industry ( Ravindranath and Mashelkar, 1984 ; Sarioğlu and Kaynak, 2017 ; Van der Velden et al, 2014 ). In 2015, nearly 15% of global plastic production was used in textile industries for the production of synthetic textiles ( Geyer et al, 2017 ).…”

Recycling

“…Even with only 12% of recycled content, recycled denim fabric has a much lower environmental impact than a similar virgin fabric, for instance, a reduction in water consumption by 9.8%, energy consumption by 4.2%, and CO 2 . Recycled shoes made from PET bottles, CDs, care tires, and other synthetic materials have also been on the market for more than a decade (Sarioğlu and Kaynak 2017;Kaynak and Sarioglu 2018;Palme et al 2017) (https://www. brooksrunning.com/en_us/06-17-2009.html).…”

Chemical Treatment in Industrial Wastewater of Polyester Synthetic Fiber Made from Recycled Polyethylene Terephthalate Bottles: Minimize Environmental Impacts

“…One of *Corresponding Author Email: yusupsetiawan60@yahoo.com (Y. Setiawan) the recycled material results from PET bottle is polyester synthetic fiber (PSF) which has a resembling shape of synthetic cotton. This material will be marketed in three forms, namely solid fiber, hollow conjugate (HC), or hollow conjugate silicon (HCS) [4][5][6].…”

“…In the screw extruder, PET bottle flakes were heated, melted and pressed through a spinerete which will produces plastic fiber filaments. The plastic fiber filaments were sprayed with water to prevent sticking to each other and then cut with a blade [2,[5][6][7][8].…”
