“…Although metals are not biodegradable as some conducting polymers and carbon-based materials are, they are sustainable because metals are accessible and highly recyclable materials. 34 Some metals, such as gold, are also biocompatible, which is important for wearable e-textiles worn against the skin. These properties make metals promising as conducting building blocks for e-textiles.…”

To realize the full gamut of functions that are envisaged for electronic textiles (e-textiles) a range of semiconducting, conducting and electrochemically active materials are needed. This article will discuss how metals, conducting polymers, carbon nanotubes, and two-dimensional (2D) materials, including graphene and MXenes, can be used in concert to create e-textile materials, from fibers and yarns to patterned fabrics. Many of the most promising architectures utilize several classes of materials (e.g., elastic fibers composed of a conducting material and a stretchable polymer, or textile devices constructed with conducting polymers or 2D materials and metal electrodes). While an increasing number of materials and devices display a promising degree of wash and wear resistance, sustainability aspects of e-textiles will require greater attention. Graphical abstract

Moreover, the common health hazards caused by the coronavirus and E-waste are respiratory problems, damage to the nervous system, skin diseases, orthopaedic complications and cancer (Ramachandra and Saira 2004;Chen et al 2011;Begum 2013;Cong et al 2018;Decharat 2018;Seith et al 2019;Davis and Garb 2019;Huo et al 2019;Gu et al 2019;Xu et al 2020;Amoabeng Nti et al 2020;Nithya et al 2020).…”

“…The main recycling methods start by a physical pretreatment, followed by pyrometallurgy, hydrometallurgy, electrometallurgy and biohydrometallurgy. E-waste contains more than 100 metals and materials which can be recycled and recovered (Cayumil et al 2014;Kaya 2016;Garlapati 2016;Priya and Hait 2017;Dutta et al 2018;Barnwal and Dhawan 2020;Nshizirungu et al 2020;Nithya et al 2020).…”

“…Electronic waste grows at an annual rate of approximately 2 million tons. Only 17.4% of the world's electronic waste was recycled, and 82.6% was left untreated or processed informally (Nithya et al, 2021). Every year, millions of electronic products reach the end of their useful life and represent thousands of tons of thermoplastics such as ABS, HIPS, and others (Qu et al, 2006).…”

Post-consumer polymers require viable actions to transfer value to the final consumer to reduce environmental impact. Worldwide, initiatives are being developed to promote the culture of recycling and thus reduce waste generation. These initiatives seek to make the work of thousands of people visible, encourage job creation, and promote businesses through incentive schemes for effective separation, collection, classification, reuse, and recycling, in the hands of consumers, collectors, and scavenges. It is necessary to emphasize that Mexico needs to develop techniques to increase the productivity of collection centers for recyclable materials and to face the challenges that recycling implies. For these reasons, the Mexican government has spoken of waste management as a national priority due to the COVID-19 pandemic, which increased urban solid waste between 3.3 % and 16.5 % in addition to what was generated under normal conditions. Also, the recycling chain provides economic income to more than 35 thousand Mexicans. Polyethylene terephthalate (PET) is an example of the most notable circular economy in Mexico because 60 % of PET bottles are recycled. Therefore, this article addresses the methods and systems in the management of urban solid waste. It focuses on post-consumer recycled plastic bottles to provide an overview of cost-effective strategies for designing and developing an affordable sorting system in Mexico from the academic field. In addition, to simplify the solution that we propose, it is recommended to combine optical techniques such as infrared spectroscopy and Raman spectroscopy with others methods that work together, such as computer vision, to develop affordable systems that address the limitations of mechanical systems.
