The textile industry, fueled by the “fast fashion” phenomenon, contributes significantly to environmental, social, and economic degradation through the rapid turnover of styles, leading to substantial waste as consumers frequently discard garments. This cycle of consumption and production is linked to the social demand added to purchase income, demonstrating the urgent need for sustainable interventions. The main objective of this study is to carry out a systematic review of the literature to identify and critically evaluate circular economy strategies implemented in the textile industry. This study conducted a systematic review of circular economy strategies in the textile industry using the PRISMA methodology. Our search spanned a ten-year period, examining 88 articles, from which 55 were selected as pertinent. The primary strategies identified include reuse, recycling, repair, and reduction, each of which is assessed through environmental, social, and economic lenses. Reuse is crucial for reducing impacts and waste, yet it is hampered by insufficient consumer incentives. Recycling shows promise but is hindered by technological and awareness barriers. Repair contributes to extending the lifespan of garments, thereby reducing the need for new production, although it encounters challenges in terms of service accessibility and consumer knowledge. The reduction involves the search for better and more sustainable materials, with the main barrier being the fast fashion. The findings suggest that reuse is not only economically viable but also capable of lessening social inequality. Recycling, however, necessitates substantial investments and the development of supportive policies. Repair, on the other hand, significantly lessens the environmental impact and can spur new economic opportunities and employment. Despite these hurdles, these strategies present viable pathways toward a more sustainable textile industry. However, achieving this requires a paradigm shift in both consumer behavior and corporate practices to embrace and optimize circular economy practices within the sector.

Constructed wetlands (CWs) attempt to simulate the physicochemical and biological processes that occur within a natural wetland and have been employed in recent decades for wastewater treatment. This work aims to review the use of CWs for domestic wastewater treatment in undeveloped or developing areas, including the amount of literature produced, the type of constructed wetland, the vegetation, the substrate, and the social benefits that have been achieved, through a qualitative methodology where different articles are collected from the Scopus and Web of Science databases after a strict revision by means of the PRISMA method (Preferred Reporting Items of Systematic Reviews and Meta-Analyses) and CASP (Critical Appraisal Skills Program). A total of 49 articles were selected, and co-occurrence and density maps were obtained; following this, three main themes and the five keywords with the highest correlation were identified. The literature analyzed in this work exposes different types of CWs where not only the hybrid, vertical, and horizontal flow systems stand out, but also the floating and aerated wetlands, which present high removal efficiencies. Additionally, new substrate materials, such as olote, palm shells, and coconut peat, and the ornamental plants usually used, such as Phragmites australis and Thypha latifolia, are discussed; however, new studies with vegetation that has been little studied but has a high potential to be implemented in areas with silvicultural characteristics stand out: Duranta repens, Pennisetum pedicellatum, and Pistia stratiotes. In conclusion, there is an advancement in the research of these systems, new configurations, substrates, and vegetation to treat domestic wastewater; in addition, these studies present an opportunity to continue studying the installation of CWs at the household level; however, compared to the other areas of application mentioned above, its implementation requires a greater challenge, since it requires a compact design and easy handling.

This article argues that although the electronic governance has been institutionalized as a public policy that promotes access to information, transparency, and control of public institutions by citizens, that does not necessarily imply that such progress has generated a positive impact in the reduction of corruption and that, consequently, other complementary actions are necessary for the execution of the electronic government public policies.

El modelo de economía lineal en el cual se compra usa y desecha, ha ocasionado un uso excesivo de los recursos naturales, la contaminación de suelo, aire y agua por una gran cantidad de desperdicios. Por otro lado, la economía circular plantea una forma diferente para utilizar los recursos naturales y mantener la actividad económica. Este documento busca describir y analizar las bases conceptuales de la economía circular. Se presenta una revisión bibliográfica en bases de datos de alto impacto sobre el tema y su papel en la actividad industrial sustentable. Durante las dos últimas décadas, la economía circular y las líneas de pensamiento relacionadas han adquirido mayor interés en la industria, academia, y a nivel gobierno. La economía circular se enfoca en desplazar la presión ambiental del crecimiento económico, lo cual, promueve sistemas de producción basados en la reducción de desechos y en la optimización del aprovechamiento de los recursos, al utilizar productos y servicios en bucles mediante el cierre de ciclos de vida de los productos ayuda a dirigir hacia un desarrollo regenerativo y por tanto, un bienestar social y económico con impacto global. Los países de la Unión Europea y China han implementado la economía circular a nivel micro, meso y macro. La economía circular proporciona una alternativa viable para sustituir el modelo lineal de economía.

Green roofs are nature-based solutions with multiple benefits for the urban environment, but they have specific polymeric components in their structure that cause a carbon footprint. This scoping review highlights the technological advance in reusing or recycling alternative materials in green roof structures worldwide, making them a part of the circular economy (CE), and the search strategies to promote them to find whether there is a relation between them. The data were collected using the Web of Science from 2012 to 2022; we also used the Bibliometrix package to analyse research development by country and the development of the topic by author’s keywords. We selected 68 open-access articles from twenty-four countries and reviewed the grey literature from the top five productive countries on this topic. Our findings show that CE strategies are performed nationally, while the green roof promotion ones are concentrated at the city level. The theme co-occurrence analysis showed that the substrate is the primary layer used with alternative materials, and the three materials most applied for it are rubber, biochar, and hydrogel. It was found that the primary purpose of optimising green roofs with alternative materials is to increase the ecosystem services they provide and indirectly function within the circular economy; still, there is a gap in estimating the environmental impact of doing this as a potential CE activity.
