“…Tendo em vista esse cenário preocupante das indústrias, incluindo a têxtil, em 2015 a Organização das Nações Unidas (ONU) adotou a Agenda 2030 para o Desenvolvimento Sustentável, na qual constam 17 Objetivos de Desenvolvimento Sustentável (ODS). Esses objetivos têm como intuito a transformação do mundo, com a finalidade de, entre outras coisas, trazer soluções para o problema da crescente geração de resíduos e preservação do meio ambiente e de todas as espécies, com melhor qualidade de vida para os habitantes do planeta, almejando-se alcançar esses objetivos até 2030 (OLIVEIRA et al, 2021;NA-ÇÕES UNIDAS, 2022).…”

“…Materiais têxteis são definidos como estruturas compostas de fibras finas e flexíveis que podem ser de origem natural, artificial, sintética ou uma combinação dessas três. Esses materiais podem ser utilizados na confecção de roupas, calçados, acessórios, roupas de cama, mesa e banho, tapetes, revestimentos de móveis, cortinas, artigos de decoração, artesanato, entre outros -o que torna a indústria têxtil um segmento de grande importância econômica e social, pois os seus produtos estão presentes em praticamente todos os tipos de ambientes (OLIVEIRA et al, 2021).…”

A indústria da moda tem elevada importância no cenário mundial por diversos aspectos, por exemplo, em termos de receita, o que repercute diretamente na geração de empregos. No entanto, o impacto ambiental causado pelos processos relacionados à produção e descarte de materiais no setor é bastante preocupante, principalmente quando consideradas as projeções de crescimento para os próximos anos. Para nortear uma evolução sustentável em nível global nesse incremento do setor produtivo, é de suma importância levar em consideração os Objetivos de Desenvolvimento Sustentável, que apontam para a tomada de decisões de empresas, ampliando a importância de aspectos relacionados a impactos ambientais, sociais e de governança. No tocante às soluções a serem empregadas na indústria têxtil, destaca-se o desenvolvimento de matérias-primas com apelo sustentável. Uma das alternativas mais promissoras para a síntese de materiais tecnológicos é a biofabricação, que basicamente utiliza fundamentos de biologia, ciência dos materiais, engenharia mecânica, entre outras áreas, para conceber biomateriais que, no contexto têxtil, sejam inovadores em termos da diminuição de impactos ambientais para confecção, com descarte facilitado e aplicabilidade semelhante à dos materiais mais usuais, como algodão e couro. Nesse cenário, estão na vanguarda os biomateriais confeccionados a partir de micélio e celulose bacteriana. Neste artigo, foram explorados alguns aspectos importantes pertinentes ao conceito de biofabricação e sua utilização no panorama nacional e internacional da indústria têxtil, direcionados principalmente para as tecnologias de micélio e celulose bacteriana, que, no momento, têm mais notoriedade em termos de volume de investimentos e divulgação publicitária de grandes marcas globais.

“…Textile recycling rates (including reuse and remanufacture) account for only 13% of world clothing, and usually this small recycled amount is used in lower-value applications [1]. Textile industry manufacturing activities have experienced few changes in relation to traditional production systems, this being especially true in emerging countries, which account for the majority of production [11]. Recycling and reusing textiles could help to reduce the production of new textiles from raw materials and the associated use of chemicals, water, and energy in the production stage [12].…”

Post-Consumer Textile Waste Classification through Near-Infrared Spectroscopy, Using an Advanced Deep Learning Approach

et al. 2022

View full text Add to dashboard Cite

The textile industry is generating great environmental concerns due to the exponential growth of textile products’ consumption (fast fashion) and production. The textile value chain today operates as a linear system (textile products are produced, used, and discarded), thus putting pressure on resources and creating negative environmental impacts. A new textile economy based on the principles of circular economy is needed for a more sustainable textile industry. To help meet this challenge, an efficient collection, classification, and recycling system needs to be implemented at the end-of-life stage of textile products, so as to obtain high-quality recycled materials able to be reused in high-value products. This paper contributes to the classification of post-consumer textile waste by proposing an automatic classification method able to be trained to separate higher-quality textile fiber flows. Our proposal is the use of near-infrared (NIR) spectroscopy combined with a mathematical treatment of the spectra by convolutional neural networks (CNNs) to classify and separate 100% pure samples and binary mixtures of the most common textile fibers. CNN is applied for the first time to the classification of textile samples. A total of 370 textile samples were studied—50% used for calibration and 50% for prediction purposes. The results obtained are very promising (100% correct classification for pure fibers and 90–100% for binary mixtures), showing that the proposed methodology is very powerful, able to be trained for the specific separation of flows, and compatible with the automation of the system at an industrial scale.

“…The textile sector is considered to be one of the largest sectors in the manufacturing industry in the world. In Brazil alone, the segment is responsible for generating 1.5 million direct jobs, being considered the largest textile chain in the West (Abit 2020) and employs 75 million people worldwide (De Oliveira et al 2021). However, its expansion and maintenance cause damage to the environment, since the dyeing and washing processes of the fabric generate a large volume of effluents containing xenobiotic compounds, including dyes (Rodríguez-Couto 2009;Singh 2017).…”

“…Considered chemically stable and difficult to remove when discarded in the environment (Guaratini & Zanoni 2000;Choi 2020), it is one of the main causes of wastewater coloring originated from textile effluents. The yarn dyeing process requires large amounts of water: it is estimated that for each kilogram of manufactured product, 200 to 400 liters of water are required, 88 % of which will be discarded with more than 10,000 by-products, as chlorinated compounds, salts, auxiliary chemicals, surfactants and especially dyes (Sen et al 2016;Almeida et al 2016;Singh 2017;Choi 2020;De Oliveira et al 2021).…”

Trametes lactinea and T. villosa collected in Brazil are able to discolor indigo carmine

et al. 2022

Dyes used in the textile industry contribute significantly to the increase of water pollution as they are disposed of, most of the time, without proper treatment. Indigo carmine is a synthetic dye widely used in the coloring of jeans and is considered difficult to remove, causing irreversible damage to the food chain in ecosystems. Mycomediation appears as an economical and sustainable way to treat textile effluents, and this work tested three strains of Trametes collected in Brazil against the ability to discolor the indigo carmine and also the activity of laccase, lignin and manganese peroxidases. The experiment was carried out in Kirk medium under static, non-sterile condition, at ± 28 °C for 120 h. Trametes lactinea (URM8350) discolored 81.40 % of the indigo carmine, T. lactinea (URM8350) 85.09 % and T. villosa (URM8022) 96.11 %. Laccase was detected in all specimens. Manganese peroxidase was detected in T. villosa and T. lactinea (URM8354), while lignin peroxidase was not detected in any of the isolates. The ability of T. lactinea to discolor dyes is reported for the first time. The discoloration rates demonstrate the ability of the strains to discolor carmine indigo and their promising use in the discoloration processes in wastewater from the textile segment.
