This work aimed to review the recent scientific research, focused on the application of recycled fibers, taken from textile waste, in the field of composite materials to fulfill the eco-sustainability requirements of textile manufacturing, and promote actions for a circular economy. The yarns and fabric production represent one of the most polluting processes of the industrial world. The harmful environmental impact of the textile process has been described by reporting the different treatments involving the raw material and the filament fabrication, and concerning the uses of insecticides, fertilizers, and many other chemicals for improving the quality of the final products. In addition, solid textile waste constituted a further additional issue for the environmental sustainability of fabric production. Various strategies have been discussed and in part already adopted by many companies to recover waste fibers and prevent them from ending up in landfills. The alternatives of fiber recycling for composite realization have been presented by reporting several recent studies involving the uses of recycled fibers from the textile waste embedded in different matrices: thermoplastic polymer, thermosetting resins, natural constituents, and concrete in light of specific applications.

Of Greece

The aim of this report is to provide a summary of the latest developments in the textile archaeology of Greece and the broader Aegean from the Neolithic through to the Roman period, focusing in particular on recent research on textile tools. Spindle-whorls and loomweights appeared in the Aegean during the Neolithic and by the Early Bronze Age weaving on the warp-weighted loom was well established across the region. Recent methodological advances allow the use of the physical characteristics of tools to estimate the quality of the yarns and textiles produced, even in the absence of extant fabrics. The shapes of spindle-whorls evolved with the introduction of wool fibre, which by the Middle Bronze Age had become the dominant textile raw material in the region. The spread of discoid loomweights from Crete to the wider Aegean has been linked to the wider Minoanization of the area during the Middle Bronze Age, as well as the mobility of weavers. Broader issues discussed in connection with textile production include urbanization, the spread of different textile cultures and the identification of specific practices (sealing) and previously unrecognized technologies (splicing), as well as the value of textiles enhanced by a variety of decorative techniques and purple dyeing.

In the frame of a circular economy, the maximization of secondary raw-material recovery is necessary to increase the economic and environmental sustainability of landfill mining and reclamation activities. In this paper, the polyethylene-rich plastic fraction recovered from the reclamation of an abandoned industrial landfill (landfill-recovered plastic, LRP) has been characterized through spectroscopic, thermal, morphological, and mechanical analyses. Then, an economically viable valorization and recycling strategy was set up. The effectiveness of this strategy in the enhancement of LRP properties has been demonstrated through morphological and mechanical characterizations.

Abstract Environmental issues, especially those related to the over-exploitation of natural resources, are leading towards considering alternative solutions and new approaches, such as the circular economy. Currently, some key elements of the circular economy approach are sustainable procurement of raw materials, improvement of production processes and ecological design, adoption of more sustainable distribution and consumption models, development of secondary raw material markets. This work aims to analyse the use of hemp as a building material, replacing traditional construction materials, but respecting at the same time the thermal, insulating and acoustic characteristics required in the construction of a building. The methodology used was Life Cycle Assessment (LCA), which considered the hemp cultivation phase and the production phase of hemp-lime (“hempcrete”) walls. The hempcrete product was compared with two different solutions: a hemp and lime block, and a traditional perforated brick block with external insulation in polystyrene. In particular, the differences among the products in terms of embodied energy and net CO2 emissions were analysed. Results showed that the hempcrete wall had better environmental performances than the other two solutions.

Residual Biomass

The use of residual biomass of forest and/or agricultural origin is an increasingly common issue regarding the incorporation of materials that, until recently, were out of the typical raw material supply chains for the production of biomass pellets, mainly due to the quality constraints that some of these materials present. The need to control the quality of biomass-derived fuels led to the development of standards, such as ENplus®, to define the permitted limits for a set of parameters, such as the ash or alkali metal content. In the present study, samples of vine pruning, and ENplus®-certified pellets were collected and characterized, and the results obtained were compared with the limits presented in the standard. The values presented from vine pruning approximated the values presented by Pinus pinaster wood, the main raw material used in the production of certified pellets in Portugal, except for the values of ash, copper (Cu), and nitrogen (N) contents, with vine pruning being out of the qualifying limits for certification. However, it was found that the incorporation of up to 10% of biomass from vine pruning allowed the fulfillment of the requirements presented in the ENplus® standard, indicating a path for the implementation of circular economy processes in the wine industry.

Different Levels

Textile recycling is an important contemporary issue and a field of research for which the aim is a circular economy in order to hinder the negative impact of increasing textile consumption on environment and climate. However, when it comes to textiles, the linear economy has a short history. This article is about textile recycling and the trade of rags during a long nineteenth century. The amount of textiles increased in Swedish households, leading to an increase also in the supply of rags. A number of changes led to a growing demand for rags during the first half of the nineteenth century as a resource for the production of paper, followed in the latter half of the century by a growing demand for wool rags within the textile industry. While the importance of rags for the paper industry is well known, this article sheds new light on the importance of rags for textile production. Sources show that as much as 40 percent of the wool used within Swedish wool manufactures at the end of the nineteenth century came from wool rags. The trade with rags was performed at different levels: from individual rag collectors and small rag­and­bone dealers to a large­scale international trade. The circular economy of textiles meant that textile waste became a nec­essary part of a growing textile production, which in turn created possibil­ities for an83 increased consumption and thus more textile waste. Thus, this article supports previous research pointing out that waste not only was the necessary, unfortunate bi­product of industrialization, but also a prerequisite for increased production.

Crucial Difference

The circular economy (CE) is considered a key economic model to meet the challenge of sustainable development. Strenous efforts are focused on the transformation of waste into resources that can be reintroduced into the economic system through proper management. In this way, the linear and waste-producing value chain problems are solved, making them circular, and more sustainable solutions are proposed in those chains already benefiting from circular processes, so that waste generation and waste are reduced on the one hand, and on the other, the non-efficient consumption of resources decreases. In the face of this current tide, there is another option that proposes a certain nuance, based on the premise that, although circular systems promote sustainability, it does not mean that they are in themselves sustainable, given that, in the first place, the effects of CE on sustainable development are not fully known and, on the other hand, the CE model includes the flow of materials, with only scant consideration of the flow of non-material resources (water, soil and energy). This paper aims to contrast both currents from an empirical viewpoint. To achieve this, a sustainability analysis of the circular waste management systems measured through a sustainability indicator, the carbon footprint (CF), as a main sustainable indicator in climate change action, is carried out. A crucial difference between circular models that promote waste management and those that do not is found in the collective systems of extended producer responsibility (or CPR). One of the most efficient recycling processes in Europe, waste tire management, has been chosen. Thus, the aim is to verify the sense of including environmental sustainability indicators, as CF, in the process of these systems. A sustainability management model (SBA) applies to End-of Life tire collection systems (ELT). This model is based on the accumulation of environmental impacts through the activities that generate them. To be transparent, this study requires a publicly recognized CF, so the study is focused on SIGNUS, the main Spanish waste tires CPR. The results achieved allow us to conclude that CF is much lower using CPR than non-linear processes. Despite the role that CPR have in the management and use of waste as secondary raw material, it is a priority to focus efforts on their redesign in order to reduce waste. In terms of circular economy, all actions are necessary in order to achieve system efficiencies, even when externalities occur in this process.

With higher level of the ecological crisis and the impacts of climate change becoming more and more visible every year, there is an urgent need to search for ways to render our society more sustainable. The purpose of this article is to study the influence of mindful consumption on the transition towards circular economy. Documentary study and literature review were used for data collection. The problems of irrational consumption were examined, circular economy principles were investigated, and explore how right mindfulness effects consumer’s behaviors in the consumption process and how it influences the business sector towards circular economy. Results showed that right mindfulness, when applied to an individual’s consumption behaviors, it can promote individuals’ awareness of waste problems, resource depletion, pollution, environmental degradation and climate change when they make their decision on purchasing. Thus, their consumption process develops in more sustainable way which contributes to resources conservation and environmental sustainability. As a result, it will influence business sector to make a transition towards circular economy; reducing raw material extraction, designing and manufacturing more sustainable/eco-friendly products, and using more recycle materials. Circular economy concept is a great move towards environmental sustainability. Consumers play an important role in the economic system of a nation. If there is no consumers’ effective demand, the producers would have no motivation to produce and sell to consumers. To move forwards on the path towards circular economy, consumers are required to make their choice with mindfulness.

The textile and clothing industry sector has today a big environmental impact, not only due to the consumption of water and the use of toxic chemicals but also due to the increasing levels of textile waste. One way to reduce the problem is to circularise the, currently linear, textile and clothing value chain, by using discarded clothes as raw material for the production of new clothes, transforming it into a model of circular economy. This way, while reducing the need to produce new raw materials (e.g. cotton), the problem of textile waste produced is also reduced, thus contributing to a more sustainable industry. In this article, we review the current approaches for traceability in the textile and clothing value chain, and study a set of technologies we deem essential for promoting the circular economy in this value chain – namely, the blockchain technology – for registering activities on traceable items through the value chain, and the Internet of Things (IoT) technology, for easily identifying the traceable items’ digital twins.

Many of the processes and products associated with modern lifestyles have negative effects on the environment. Among the significant consequences are the rising costs of treating and disposing of excessive amounts of waste. Proper management of the large amounts of waste generated by the confection industry is of high importance to the good of society. Solving the problem of textile waste is of great importance for the garment production facilities in order to increase competitiveness, make additional profits and reduce disposal costs. In this paper were analyzed two confection companies, in order to determine the amount of textile waste that occurs in both companies, and also was made a research for utilization of the generated textile waste through its application as a raw material for the production of composite materials.
