Second-hand clothing is increasingly promoted as a sustainable alternative to reduce the fashion industry’s environmental impact, yet evidence on why consumers purchase second-hand apparel remains fragmented across disciplines. This literature review synthesizes prior research to identify the main motivational drivers and inhibitors of second-hand clothing purchasing and to translate them into a coherent conceptual explanation. We reviewed and conceptually integrated the academic literature on second-hand apparel consumption, focusing on how studies define, operationalize, and relate sustainability concerns, economic value, uniqueness and identity motives, and socio-cultural influences to purchase intention and behavior. The reviewed evidence indicates that pro-environmental values often coexist with utilitarian and symbolic motives, while barriers frequently involve perceived risk (e.g., quality and hygiene), effort, and access constraints. Building on this synthesis, we propose an integrative model that organizes key antecedents and mechanisms leading to purchase intention and repeat purchasing, highlighting enabling conditions and boundary factors that may strengthen or weaken these relationships. This review consolidates dispersed findings, clarifies theoretical gaps, and provides a testable framework to guide future empirical research and managerial interventions aimed at scaling circular fashion adoption.

This work provides a systematic experimental study for the electrochemical desalination of saline water using an electrospun permselective polyvinylidene difluoride (PVDF) membrane. Several nano additives were initially screened during membrane development; however, only the materials that demonstrated stable dispersion, reproducible membrane formation, and consistent electrochemical behaviour, namely graphene oxide (GO) and carbon nanotubes (CNTs) were selected for full analysis in this study. Accordingly, the study focuses on pure PVDF, PVDF/GO, and PVDF/CNTs membranes integrated with an alternating Ag/AgCl electrode system. The silver electrode is prepared by spray-coating of silver nanoparticles on high surface carbon cloth, whereas the AgCl electrode was prepared electrochemically from the Ag electrode using a three-electrode electrochemical cell. The electrochemical behaviour of various modified electrodes (bare carbon cloth, Ag/carbon cloth, Ag/nafion/carbon black/PVDF, and Ag/nafion/carbon cloth) was evaluated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and X-Ray Diffraction (XRD). The electrode prepared using Nafion and PVDF as binders with carbon black as conductive additive exhibited the highest current response and lowest charge-transfer resistance. When coupled with this optimized electrode, the PVDF/GO membrane delivered the best desalination performance, achieving an ion removal efficiency of 68%, a salt adsorption capacity (SAC) of 775.40 mg/g, and a specific energy consumption (SEC) of 16.17 kJ/mole values superior to those reported in the literature.

This paper explores the feasibility of using a wireless Inductive Resonant Link (IRL) for wearable posture monitoring. The proposed system is based on magnetically coupled textile resonators and is implemented using a Single Input Multiple Output (SIMO) configuration. In particular, the setup consists of four inductively coupled resonators: one transmitting coil integrated into a textile structure and positioned on the back of the neck, and three receiving coils placed on the shoulders. The magnetic coupling between these elements varies as a function of the user’s posture, making it possible to monitor postural changes by analyzing variations in the transmission coefficients of the link. Unlike traditional sensor-based systems that require multiple components and data processing, the proposed method uses the inherent response of the inductive link to detect posture in a simple and efficient way. To validate the concept, experimental measurements of the scattering parameters were carried out using a compact and low-power vector network analyzer. The results show a consistent and measurable relationship between postural changes and variations in the transmission coefficients, demonstrating the effectiveness of the proposed system in distinguishing between different postures. The findings suggest that inductive resonant wireless links, especially when implemented with textile components, represent a promising alternative to traditional wearable sensor technologies for posture tracking. The approach offers significant advantages in terms of wearability, power consumption, and simplicity, making it suitable for applications in ergonomics, rehabilitation, occupational health, and smart clothing.

This study considers ways to increase the consumption of sustainable fashion given the significant environmental and social damages associated with the industry. A series of experiments were conducted examining the impacts of choice architecture (nudges) under field conditions in collaboration with one of Israel’s largest shopping centers. This study sought to identify which interventions at the retail level successfully motivate sustainable fashion behavioral change regarding purchases and willingness to pay more, along with agreement with several statements regarding the climate crisis and sustainable fashion. Among the types of nudges examined in this field study were providing information, increasing accessibility to sustainable alternatives and appealing to social identity in relation to demographics and green self-image. This study found that offering alternatives to consumers constituted the most effective way to “nudge” consumers toward more sustainable purchasing behavior. Nonetheless, this does not negate the contribution of providing information and strengthening social norms regarding sustainable fashion. Additionally, in all groups, most participants reported that they did not know how to distinguish between sustainable and non-sustainable fashion, nor did they believe that the clothes they purchased were actually sustainable. The findings emphasize the need for policies that will increase the accessibility of sustainable fashion. Full article

In the context of the COVID-19 pandemic, online sales have increased in recent years for many products. Responsible consumption has also been considered by households and individuals, and interest in sustainable products has positively evolved. Although sustainable products have more and more been considered by consumers and producers as appropriate alternatives, the results are still underwhelming. This study aims to demonstrate the relationship between the online sales of sustainable products and the online marketing costs expressed by the cost-per-click in Romania in the last three years. This quantitative research is a conclusive and descriptive study based on secondary data sets collected from the evidence registered in an online agency, which, in turn, was based on a sample of companies and products in three industries considered highly open to sustainable approaches: electronics; home and garden; clothing and footwear. The results show different relationships between the online marketing cost and the sales of sustainable products in the above-mentioned industries. In addition, online consumer purchasing intention is a mediator for the relationship between marketing cost and online sales in one industry only, namely electronics. The study reveals the development of the online transactions of sustainable products, considering the connection between marketing costs and subsequent sales. Full article

The environmental price of fashion has been heavily scrutinised in recent years. Slow fashion, with its emphasis on quality, design, sustainability, ethicality and local craft heritage, represents an alternative to the harmful environmental and social impact of fast fashion. Equally important, some initial evidence from qualitative research suggests that slow fashion could enhance consumers’ well-being. The present study aims to quantitatively evaluate the relationships that fast and slow fashion may have with different domains of well-being, utilising Seligmen’s influential PERMA model from positive psychology. In addition, it explores characteristics from slow fashion that may enhance garment lifetimes. An online questionnaire successfully surveyed 763 urban Chinese consumers. Results showed that consumption of slow fashion, in particular ‘customised/bespoke clothing’ that allows consumers to be actively involved in the creation process, positively predicted three well-being domains—engagement, meaning and achievement. Fast fashion, on the other hand, negatively predicted these domains. Classic/timeless design, ease of maintenance and ease of matching with other clothes emerged as the three most important characteristics that may encourage consumers’ long-term use of fashion items. Implications of the findings are discussed in the context of promoting slow fashion to enhance sustainability. Full article

Energy-saving is a mandatory research topic since the growing population demands additional energy yearly. Moreover, climate change requires more attention to reduce the impact of generating more CO₂. As a result, some new research areas need to be explored to create innovative energy-saving alternatives in electrical devices that have high energy consumption. One research area of interest is the computer visual classification for reducing energy consumption and keeping thermal comfort in thermostats. Usually, connected thermostats obrtain information from sensors for detecting persons and scheduling autonomous operations to save energy. However, there is a lack of knowledge of how computer vision can be deployed in embedded digital systems to analyze clothing insulation in connected thermostats to reduce energy consumption and keep thermal comfort. The clothing classification algorithm embedded in a digital system for saving energy could be a companion device in connected thermostats to obtain the clothing insulation. Currently, there is no connected thermostat in the market using complementary computer visual classification systems to analyze the clothing insulation factor. Hence, this proposal aims to develop and evaluate an embedded real-time clothing classifier that could help to improve the efficiency of heating and ventilation air conditioning systems in homes or buildings. This paper compares six different one-stage object detection and classification algorithms trained with a small custom dataset in two embedded systems and a personal computer to compare the models. In addition, the paper describes how the classifier could interact with the thermostat to tune the temperature set point to save energy and keep thermal comfort. The results confirm that the proposed real-time clothing classifier could be implemented as a companion device in connected thermostats to provide additional information to end-users about making decisions on saving energy.

This is the first research that has examined temporary swapping, a form of collaborative fashion consumption, that involves clothing exchange between two people that does not require the transfer of product ownership or monetary compensation. In this ethnographic study, we explored benefits, risks, and the meanings constructed by eight women before, during, and after exchanging parts of their wardrobes with a swap partner. Maslow’s hierarchy of needs was used to organize the results of interpretation of participant diaries with photographs of swapped garments and created outfits over a six-month period. While the swapping experience addressed basic physiological needs and secured free resources (more clothing to wear) for all participants, the more advanced psychological (social, self-esteem) and personal growth needs (self-actualization, transcendence) were met for only some of them. Similarly, women perceived different risks (safety and self-esteem risks). Through a holistic interpretation of the results, we discovered two critical factors determining overall temporary swapping satisfaction and success: (1) closeness of the relationship between the swap partners and (2) participant love for clothes. Temporary swapping might play a critical role in the fashion marketplace transition to sustainable consumption practices because it provides a middle ground between product ownership and non-ownership and thus facilitates gradual dematerialization of consumer lifestyle.

A modern model of water management should take into account, first of all, its responsible consumption of both tap water and water from unconventional sources. With this in mind, a study was conducted to determine the financial efficiency of rainwater harvesting systems (RWHSs) and greywater recycling systems (GWRSs) in residential buildings located in eight European countries. At the first stage, volumetric reliability was determined for different tank capacities for actual precipitation data. An economic analysis was carried out for six variants in which rainwater and greywater were used in various combinations for toilet flushing, washing, and garden watering. The implementation of alternative water systems was found to be financially unprofitable in four cities: Warsaw, Bratislava, Budapest, and Stockholm. For these cities, the variant with the lowest life cycle cost (LCC) level was always Variant 0, with conventional installations. The opposite situation was observed in the other four locations (Lisbon, Madrid, Rome, and Prague), where Variant 0 was not found to be financially profitable for any of the calculation cases analyzed. Additionally, a survey was conducted to determine the effect of social aspects, which is often the greatest barrier to the implementation of new or unknown technologies. In most of the countries surveyed, rainwater is more acceptable to society as an alternative water source than greywater. For hygiene reasons, the use of these two systems for washing clothes was of greatest concern. Full article

Over the past few decades, the production and consumption of clothing has increased exponentially, leading to a dramatic increase in the negative environmental consequences produced by the fashion industry. Given the rising pace of global warming and the rising concern about the fashion industry’s contribution to the climate crisis and its exploitative social dimensions, decision makers, politicians and government officials have begun to promote sustainable fashion through public policy. This article reviews the main barriers facing a circular economy in general and the fashion industry in particular. It considers nascent regulations emerging throughout the world in the field of sustainable fashion, applying circular economic principles to the fashion industry. Four categories of policy proposals are evaluated: Command and Control Interventions, Educational Initiatives, Incentives and Certification, grading them according to criteria of effectiveness, sustainability, feasibility, equity and compliance. The ranking process was based on an elicitation of expert judgement among a panel with expertise in the areas of sustainable fashion from the business sector, academia and civil society. Findings suggest that while some policy options appear to meet all criteria successfully, when selecting an optimal strategy for promoting sustainable fashion, there are frequently trade-offs between different alternatives.

This study aimed to evaluate the installation of a system that combines rainwater to wash clothes and greywater to flush toilets in a house located in Florianópolis, southern Brazil. The evaluation consisted of determining the potable water savings, performing a financial analysis, and verifying the possibility of using rainwater and reusing greywater according to the local legislation. The reduction in potable water consumption was determined by comparing the monthly water and sewage bill, before and after installing the system, combining rainwater and greywater. The financial analysis was performed considering the financial benefits, operational costs, costs for installing the system, and local water tariffs. After installing the system, there was a decrease of 38.0% in the monthly potable water consumption, which represents a decrease of 7.00 m³ in the monthly potable water consumption. The payback periods for the old and new water tariffs were equivalent to, respectively, ten years and seven months, and eight years and five months. Both rainwater and greywater had parameters with concentrations higher than the limits established by the legislation. Therefore, the rainwater had to go through a device for discarding the first flush and needed disinfection; and the greywater needed to go through a treatment process. The results indicated that the system combining rainwater and greywater shows significant potential for potable water savings, which can be a good alternative to the preservation of potable water resources. It is important to note that current studies on rainwater use and greywater reuse are mainly related to non-potable purposes, but it was shown herein that rainwater can be used for washing clothes.

In order to make our production and consumption systems more sustainable, there is a need to further explore and support novel business models with higher sustainability potential. Use-oriented product-service systems (u-PSS) are considered a promising alternative to traditional ownership-based business models, as they may result in lower environmental impacts. The presence of u-PSS in consumer goods markets, however, is still small. This is due in part to the nature of the products and lack of consumer acceptance of u-PSS. Lately, however, companies in Sweden have begun offering u-PSS for consumer goods, thereby challenging earlier findings. Understanding about how companies encourage consumers to select u-PSS over ownership-based options is still lacking. We investigate this question by conducting interviews with and analysing websites and publicly available company reports of seven Swedish companies from three consumer goods sectors: clothing, eyewear and furniture. We found that, while consumer barriers to u-PSS found in previous studies—uncertainty and trust, economics and costs and desire to own—persist, tailoring elements of u-PSS business models to different markets, sectors and consumer segments can help address these barriers and ensure u-PSS resonate with consumers. The study also applies the concept of consumer perceived value to show how emphasising different dimensions of value—financial, functional, emotional and social—provided by u-PSS may help increase their acceptance and adoption.

Electronic shopping is getting more and more popular, and it is not only clothes and electronics that people buy online, but groceries and household products too. Based on real-life data from a major cosmetics and household products retailer in the Czech Republic, this study set to assess the life cycle environmental impact of parcel delivery. Two archetype parcels containing common household and hygiene products were designed and packed in two distinct ways, and the environmental impact was quantified using the Life Cycle Assessment method. It showed that it is environmentally beneficial to use plastic cushions to insulate the goods instead of paper. However, the most important process contributing to the environmental burden was found to be electricity consumption in the logistics center. Hence, the importance of energy efficiency and efficient space utilization was demonstrated on alternative scenarios. Since the cardboard box the goods are packed in turned out to be another important contributor, an alternative scenario was designed where a reusable plastic crate was used instead. Even though the scenario was based on several simplistic assumptions, it showed a clear potential to be environmentally beneficial. In the study, contribution of other processes was scrutinized, as well as sensitivity to variation of parameters, e.g. transportation distances. The main scientific contribution of this work is to show the importance of logistics and distribution of products to end customers in the rapidly developing field of electronic retail of household products.

The growing importance of the Internet of Energy (IoE) brands the high-renewables electricity system a realistic scenario for the future electricity system market design. In general, the whole gist behind the IoE is developed upon a somewhat broader idea encompassing the so-called “Internet of Things” (IoT), which envisioned a plethora of household appliances, utensils, clothing, smart trackers, smart meters, and vehicles furnished with tiny devices. These devices would record all possible data from all those objects in real time and allow for a two-way exchange of information that makes it possible to optimize their use. IoT employs the Internet Protocol (IP) and the worldwide web (WWW) network for transferring information and data through various types of networks and gateways as well as sensor technologies. This paper presents an outline stemming from the implications of the high-renewables electric system that would employ the Internet of Energy (IoE). In doing so, it focuses on the implications that IoE brings into the high-renewables electricity market inhabited by smart homes, smart meters, electric vehicles, solar panels, and wind turbines, such as the peer-to-peer (P2P) energy exchange between prosumers, optimization of location of charging stations for electric vehicles (EVs), or the information and energy exchange in the smart grids. We show that such issues as compatibility, connection speed, and most notoriously, trust in IoE applications among households and consumers would play a decisive role in the transition to the high-renewables electricity systems of the 21st century. Our findings demonstrate that the decentralized approach to energy system effective control and operation that is offered by IoE is highly likely to become ubiquitous as early as 2030. Since it may be optimal that large-scale rollouts start in the early 2020s, some form of government incentives and funding (e.g. subsidies for installing wind turbines or solar panels or special feed-in-tariffs for buying renewable energy) may be needed for the energy market to make early progress in embracing more renewables and in reducing the costs of later investments. In addition, there might be some other alternative approaches aimed at facilitating this development. We show that the objective is to minimize the overall system cost, which consists of the system investment cost and the system operating cost, subject to CO2 emissions constraints and the operating constraints of generation units, network assets, and novel carbon-free technologies, which is quite cumbersome given the trend in consumption and the planned obsolescence. This can be done through increasing energy efficiency, developing demand side management strategies, and improving matching between supply and demand side, just to name a few possibilities.

The rapidly growing demand for clothing in connection with the resource requirements and the emissions along the textile chain as well as the prevailing working conditions in the textile industry cause serious environmental and social problems. The question is asked, whether changes in consumption towards more sustainably produced clothing and, finally, a reduction of clothing consumption are achievable against the background of the existing consumption-related patterns of attitudes and behaviors. A representative survey was conducted in Germany (N = 2000) to tackle the consumer-related aspects of this question. The characteristics of consumption-related attitudes in the different population segments were determined. Factors were identified that affect the buying and use of clothes as well as the efficiency, consistency, and sufficiency supporting consumption alternatives. The results show that some preconditions for a broader diffusion of more sustainable alternatives in clothing consumption are given in Germany, such as a widespread general sustainability and problem awareness. In some population segments, social norms supporting more efficiency and consistency in the clothing sector are effective, and social and ecological buying criteria have a relatively high importance. However, there are also strong attitudinal obstacles, particularly regarding the restriction of clothing consumption. Full article
