Special Issue Information

Dear Colleagues,

The textile industry is one of the largest contributors to environmental pollution due to excessive resource consumption, synthetic fiber waste, and limited recycling practices. This Special Issue aims to address recent advancements in textile recycling technologies, circular economy approaches, and sustainable materials. We seek contributions that explore innovative recycling methods, chemical and mechanical processes, life cycle assessments (LCAs) of textile waste management, and technological advancements promoting circularity in the textile industry. The goal is to provide a comprehensive overview of strategies that can help reduce the environmental footprint of textiles and accelerate the transition to a more sustainable industry.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Textile waste management remains a critical environmental challenge. Valorization through thermochemical routes such as pyrolysis offers a sustainable pathway within the circular economy. In this study, carbonaceous materials were obtained from the pyrolysis of 100% cotton textile residues and subsequently activated with sodium thiosulfate (Na2S2O3). The physicochemical and leaching behaviors of the activated (CA) and non-activated (C) chars were assessed in aqueous solution under controlled pH conditions (3, 7, and 11). Activation significantly increased the specific surface area (from 90 to 975 m2 g−1). Leaching tests revealed that acidic conditions (pH = 3) enhanced the release of major elements following the order Na > Ca > K for C and S > Ca > Na for CA. Despite this, all concentrations of major and trace metals remained well below regulatory discharge limits. Anionic species (Cl, SO42−) increased slightly after activation but also stayed within safe thresholds, and chemical oxygen demand (COD) values were low (0–9 mg O2 L−1), indicating negligible organic leaching. Overall, the findings show that the structural quality of textile-derived chars was improved by Na2S2O3 activation without compromising their environmental stability, validating their applicability as effective and safe adsorbents for wastewater treatment applications.
