The development of technical yarns containing recycled textile fibres and natur...
Azevedo, Tiago Jorge Mendonça Pinto; Silva, Ana Catarina; Brás, Duarte Rodrigues; Guimarães, Renato Filipe Costa Rodrigues; Ferreira, Diana P.The textile industry is one of the most polluting sectors globally. In 2023, the global production and consumption of textiles reached approximately 100 million tonnes, with most of these textiles being disposed of in landfills or incinerated. In response to the increasingly demanding EU regulations, the mitigation and valorisation of textile industry waste has become imperative. Recycling technologies can be r...
Sequential T790M mutation testing and changes in the therapeutic approach after...
Estevinho, Fernanda; Silva, Ana Catarina; Cirnes, Luís; Amaro, TeresinaThe EGFR mutation is identified in 10-50% of patients with non-small cell lung cancer (NSCLC). After first-line therapy, with 1st or 2nd line tyrosinacinase (TKI) inhibitors, in patients with NSCLC and a sensitizing EGFR mutation the most frequent mechanism of resistance is the acquisition of a T790M mutation, in 50-70%. We present the clinical case of a woman with NSCLC, cT2bN1M1b, stage IV with cerebral and a...
A correlation-based approach for predicting humic substance bioactivity from di...
Silva, Ana Catarina; Bento, M. Fátima; Rocha, José Pedro Pereira Rebelo; Geraldo, Dulce; Proença, M. Fernanda R. P.; Antelo, Juan; Fiol, SarahThe efficient characterization of compost quality is essential for optimizing its application in agriculture and soil improvement. In this study, a correlation-based approach was employed to evaluate relationships between physicochemical properties, structural features, and reactivity indicators of compost extracts—fulvic acid-like (FA-L), humic acid-like (HA-L), and dissolved organic matter (DOM)—and their res...
Alternative organic solvents for elastane removal from textile waste: a case st...
Silva, Ana Catarina; Azevedo, Tiago Jorge Mendonça Pinto; Ribeiro, Ana Isabel Ferreira; Chaves, Diego Morais; Fangueiro, Raúl; Ferreira, Diana P.The increasing demand for sustainable textile recycling has driven the search for effective methods to separate and recover valuable materials from fabric waste. Elastane, a widely applied synthetic polymer in the textile industry due to its flexibility and durability, presents considerable environmental challenges after the material life cycle. Thus, the development of effective methods for elastane degradatio...
Addressing absenteeism through a community of practice in higher education: The...
Marinho, Paula; Casanova, Joana R.; Valente, Teresa Maria Fernandes; Henriques, Renato F.; Gonçalves, Luís Miguel Barros; Moura, C.; Silva, Ana CatarinaThis article presents Community of Practice for Attendance (CoP +Attendance), awarded funding through the 7th Edition of the University of Minho's Programme to Support Projects for Innovation and Development in Teaching and Learning [2024/2nd Call], coordinated by the IDEA- UMinho Centre, throughout 2025. The CoP +Attendance addresses absenteeism among undergraduate students. The initiative will focus in Geolog...
Reinforcing cotton recycled fibers for the production of high-quality textile s...
Azevedo, Tiago Jorge Mendonça Pinto; Silva, Ana Catarina; Machado, Gonçalo; Chaves, Diego Morais; Ribeiro, Ana Isabel Ferreira; Fangueiro, RaúlThe textile industry is under increasing pressure to adopt sustainable practices due to the significant environmental impacts associated with fiber production, including high energy consumption, water usage, and substantial greenhouse gas emissions. The recycling of textile waste, particularly cotton, is a promising solution that has the potential to reduce landfill waste and decrease the demand for virgin fibe...
Selective elastane removal using DMSO–DBN under moderate temperatures: from pur...
Azevedo, Tiago Jorge Mendonça Pinto; Silva, Ana Catarina; Chaves, Diego Morais; Fangueiro, Raúl; Ferreira, Diana P.Selective removal of elastane from textile blends is a critical factor for fibre-to-fibre recycling, since even low elastane content compromises the mechanical shredding efficiency, contaminates recycled streams, and limits the spinnability of recovered fibres. In this work, we investigate dimethyl sulfoxide (DMSO) as a solvent system for elastane degradation under moderate temperatures, both in the absence and...

Technical yarns containing recycled fibers from pre-consumer textile residues
Azevedo, Tiago Jorge Mendonça Pinto; Silva, Ana Catarina; Brás, Duarte Rodrigues; Guimarães, Renato Filipe Costa Rodrigues; Ferreira, Diana P.The textile industry is widely recognized as one of the world's most polluting industries. It produces a considerable amount of waste, including residual waste from the manufacturing process itself, as well as waste resulting from the utilization of products by consumers and industrial waste from production activities (i.e. post-industrial and pre- and post-consumer waste). In the specific case of the post-indu...
Transforming post-industrial textile cutting waste into circular garments: a re...
Brás, Duarte Rodrigues; Silva, Ana Catarina; Azevedo, Tiago Jorge Mendonça Pinto; Fangueiro, Raúl; Ferreira, Diana P.The exponential growth of global textile fibre production has intensified environmental pressures, notably through the generation of substantial volumes of waste, elevated CO₂ emissions, and widespread water pollution. In response to these challenges, this study presents a sustainable and scalable approach to textile waste management, focusing on the mechanical recycling of post-industrial cutting waste — a sig...
