Washing Clothes

ingridha on 30. October 2023

Ingun Grimstad Klepp & Kirsi Laitala

Clothes must not only suit the user and the occasion but also be clean for us to be well dressed. The meaning of cleanliness and the methods to achieve this goal has changed throughout history, but it has been central in our clothing practices. In this chapter, we will show how the understanding of dirty and clean clothes and the work of keeping them clean has changed in the last 200 years. The starting point will be the laundry in Norway, but when we discuss the more current times, the global washing practices will be included. As important as these technical and aesthetic questions are the cultural aspect. How have the perceptions of what is clean and what is dirty changed, and what consequences does this have for being well-dressed and for the work with the laundry? We discuss the growth in the amount of laundry, and after the 1970s also the decline in finishing work, especially related to removing the wrinkles. The technical and aesthetic aspects are important, such as whiteness, stains, and not least, odors. The chapter concludes with a discussion of the environmental impacts of laundry, including consumption of water, chemicals, and energy, and spreading of microplastics.

Regulating Fast Fashion out of Fashion

Lisbeth Løvbak Berg on 10. September 2023

Authors: Ingun Grimstad Klepp and Kerli Kant Hvass

Abstract

Among sustainable fashion and textile themes, product durability has recently come into focus within EU policy making. The dominant understanding is that increased textile lifespan will reduce environmental impacts, but this intrinsic link is not supported by research. The volume of clothing produced poses the greatest environmental burdens. Increased clothes availability leads to longer lifespan due to reduced utilization. To reduce the environmental impact of increased textile volumes measures should be expanded to encompass not only product design, life-prolonging, and end-of-life strategies, but also the volume of products to market. This concept paper contributes to the debate on how to address the growing amount of textile waste by applying the knowledge gained from consumer research regarding clothing use and proposing a regulatory measure called Targeted Producer Responsibility (TPR). The central method of TPR is waste analyses which relies on actual use – or non-use – of products as the starting point for eco-modulated fees. TPR reverses EPR and uses waste for overproduction knowledge, thus proposing a tool that can potentially reduce the total environmental impact of textiles.

THE PLASTIC ELEPHANT: Overproduction and synthetic fibres in sustainable textile strategies

Lisbeth Løvbak Berg on 30. June 2023

Authors: Ingun Grimstad Klepp, Lisbeth Løvbak Berg, Anna Schytte Sigaard, Tone Skårdal Tobiasson and
Lea Gleisberg

Summary

In this report, we examine national, international and corporate strategies for sustainable textiles to understand if and how they embrace the increased production volumes based on synthetic materials, which can be referred to as the ‘plastic elephant in the room’. This is done through a lens of four questions. First, we look at whether the strategies discuss growth in production volumes and possible measures to stop this growth. Second, we examine whether they address the plastification of textiles. By plastification, we mean the increasing share of plastic fibres used for textile production. Third, whether they discuss the raw material for plastics, and fourth, plastic waste. The results show that none of these questions that can reduce the environmental impacts of clothing production are given a central role in the strategies.

Reducing Plastic in Consumer Goods: Opportunities for Coarser Wool

Lisbeth Løvbak Berg on 28. January 2023

Lisbeth Løvbak Berg, Ingun Grimstad Klepp, Anna Schytte Sigaard, Jan Broda, Monika Rom and Katarzyna Kobiela-Mendrek.

Abstract

Production and use of plastic products have drastically increased during the past decades and their environmental impacts are increasingly spotlighted. At the same time, coarse wool, a by-product of meat and dairy production, goes largely unexploited in the EU. This paper asks why more coarse wool is not used in consumer goods, such as acoustic and sound-absorbing products, garden products, and sanitary products. This is answered through a SWOT analysis of results from a desktop study and interviews with producers of these products made from wool, as well as policy documents relating to wool, waste, textiles, and plastic. Findings show that on a product level, the many inherent properties of wool create opportunities for product development and sustainability improvements and that using the coarser wool represents an opportunity for replacing plastics in many applications as well as for innovation. This is, however, dependent on local infrastructure and small-scale enterprises, but as such, it creates opportunities for local value chains, value creation, and safeguarding of local heritage. The shift to small-scale and local resource utilization requires systemic change on several levels: Here the findings show that policy can incentivize material usage transitions, but that these tools are little employed currently.

A functioning ‘functional unit’?

Lisbeth Løvbak Berg on 12. January 2023

Ingun Grimstad Klepp and Tone Skårdal Tobiasson

What is the ‘functional unit’ of a winter coat, or a pair of boots? The ‘functional unit’ is a central concept for lifecyle assessment (LCA) based tools. In the ongoing work on the European Union’s (EU) PEFCR (Product Environmental Footprint Category Rules), this is based on the number of days of ‘usability’.

Let’s explore what this means. A ‘functional unit’ is perhaps most easily explained in terms of paint, in terms of how long a certain paint will keep the walls protected and good looking, but how does that translate to apparel?

The EU has decided that the functional unit for a winter coat – or a pair of boots – is 100 days of use. This is the expected usability (functional unit) you can expect to gain from a product before it needs replacing or repairing. So far, so good.

How to make sure Extended Producer Responsibility becomes a silver bullet

Lisbeth Løvbak Berg on 24. October 2022

This is a letter sent to commissioners and members of the European Commission in October 2022, from 4 participants in the Wasted Textiles project that explains their suggestions for a way of developing an EPR scheme that addresses volumes. They suggest an Eco-modulation based on volumes in the waste and therefore include the growing online trade.

How to make sure Extended Producer Responsibility becomes a silver bullet

We would firstly like to recognize the immense effort made by the EU Commission in launching the EU Strategy for Sustainable and Circular Textiles in the spring of 2022 and welcome the long-awaited focus on this sector. We would also like to express our appreciation of the strategy’s systemic approach to tackling the various challenges in the textile sector. We especially welcome that the strategy addresses fast fashion, the problem of synthetics and the need for EPR.

We are an applied research consortium under the umbrella of the project Wasted Textiles, which represents strong expertise on textiles, i.e., consumption and wardrobe studies (use, reuse, laundry, repair, disposal), end-of-life practices and waste analysis, fibres and measurement tools, greenwashing, marketing claims and consumer communication and, business models. We wish to offer our interdisciplinary expertise and in-depth knowledge of consumer research, waste and recycling management and policies from 30 years of research and recycling industry development. Wasted Textiles is led by Consumption Research Norway (SIFO), a non-profit, transdisciplinary research institute at the Oslo Metropolitan University.  SIFO has a history going back to the 1930s and the birth of home economics and has worked with clothing consumption from the start. Today the institute has extensive research on clothing, especially the use phase.

With this letter, we would like to express our support for the EU Commission’s work within textiles and at the same time highlight key areas of concern that need to be addressed for a much-needed systemic change within the industry. Specifically, this letter concerns the development of harmonised      EU Extended producer responsibility (EPR) rules for textiles with eco-modulation fees as part of the forthcoming revision of the Waste Framework Directive in 2023.

Norway was one of the first countries in Europe to implement Extended Producer Responsibility for packaging waste and electric electronic equipment (EE goods) and batteries during the early 1990s. The law from 2017 replaced the voluntary industry agreements from 1994. The National Waste Association of Norway (Avfall Norge, part of the Wasted Textiles consortium) has a history dating back to 1986. Norway also got its first Pollution Act in 1981.

We believe that harmonised EU EPR rules for textiles can be an important instrument to bring the needed systemic changes in the textile sector. In line with a recent report by Eunomia “Driving a Circular Economy for Textiles through EPR”, we believe the aim of the EPR scheme must be the reduction of environmental impacts from the textile sector. This is in line with the original definition of EPR from the Swedish researcher Thomas Lindhqvist from 1992:

“Extended producer responsibility is an environmental protection strategy to achieve an environmental goal of reduced total environmental impact from a product, by making the manufacturer of the product responsible for the entire life cycle of the product and especially for the return, recycling and final disposal of the product. The extended producer responsibility is implemented through administrative, financial and informative instruments. The composition of these instruments determines the exact form of the extended producer responsibility.”

Our point of departure is that the biggest challenge in the textile sector is overproduction. The amount of clothes produced and sold has increased drastically in the past 20 years. This means that each individual garment is used less and less. In order to reduce environmental burdens, measures are therefore needed that not only address the product’s design but above all the quantity of products. It is those who produce the clothes that are used the least – or never even used at all – who emit the most. At the same time, it is the clothes that are worn the longest that burden the environment and waste systems the least. In other words, we want to take the waste hierarchy seriously by showing how EPR can prevent waste and not just stimulate increased reuse and recycling.

As a starting point, and in line with the beforementioned Eunomia report, we believe the aim of the scheme must be the reduction of environmental impacts. This is achieved most quickly and efficiently by reducing the EU’s production and import of new apparel and other textile products. But, for EPR to move towards a circular economy for textiles and not simply be an exercise in transferring costs, as the report formulates it, EPR must be designed smartly. One of the challenges with EPR, that the report points to, is precisely taking the waste hierarchy seriously, e.g., by not favouring recycling over reuse, ensuring that the environmental fee is high enough to have an effect on production volumes, and that the scheme includes the growing online shopping with direct imports.

The biggest challenge is overproduction: EPR must be designed accordingly

We are concerned that the measures proposed in the EU’s textile strategy (PEF, the Eco-design Directive and EPR) focus primarily on the product and its design together with end-of-life strategies (recycling), and thus not on the possible systemic changes that are pressing. In order to reduce the environmental impact of large volumes of textiles (fast fashion), measures are therefore needed that not only address the product’s design and strategies for prolonged- and end-of-life textiles, but also the number of products produced. If the EU is to achieve its goal of making fast fashion out of fashion, the means must be directed at factors that make fast fashion unprofitable. In extreme cases, we are talking about disposable products, in addition to the destruction of products that have never been used at all. It is not the design of each individual product that distinguishes fast fashion, which means that eco-design criteria will therefore not have the desired effect standing alone. A weakness of most of the EPR systems that have been implemented so far is that they do not take the issue of quantity seriously.

If the EU is to achieve its goal of making fast fashion out of fashion, the means must be directed at what makes fast fashion profitable: large volumes and rapid changes. The commission has been discussing a ban on greenwashing and planned obsolescence. In fact, fast fashion is planned obsolescence by definition. The clothes are not meant to last. Not because of bad quality or bad design, but because there is a new trend coming ever more often and faster.

The work on the development of PEF (Product Environmental Footprint) for clothing has also shown that it is extremely difficult to develop eco-design criteria for clothing, as the criteria for what constitutes good clothing are so varied and person-specific. Focusing on the product’s design does not capture the most important: whether there is an actual use for the product.

We believe that EPR can be designed so that quantity and speed are taken into account. This must be done by studying the use and disposal phases, and possibly also the quantity and speed of production. Those clothes that are used little and cost a lot to reuse/recycle will be the most expensive to put on the market.

If this is done and combined with sufficiently high fees, we ensure that one of the instruments in the textile strategy actually works, i.e., brings systemic change and is thus a true silver bullet.    

The importance of the use phase

By the use phase we mean the time the product is in use. The longer this is, the less waste is created. Currently, textile use is an area with limited knowledge and data, however, in order for the EPR rules to have an impact on fast fashion and the related overconsumption, it is highly important, that we make sure that an EPR scheme considers use-related aspects. The use phase for clothing can be measured in the number of times something is used, or how long it is used. The latter is far easier than the former to measure. Instead of trying to guess which products will be used for a long time and modulating the fee on design parameters, it is possible to measure how long products from different (larger) retailers remain in use. Using “picking analysis” (a type of waste audit, an established method for analysing waste streams), sample analyses of textile waste and textiles donated for reuse, an average usage phase can be estimated.

The system will be far more accurate when the year of production is included in the mandatory labelling of clothing, a long overdue requirement. The time-lapse from when the product is put on the market until it goes out of use will give the manufacturers a score which is then multiplied by the volumes of the various brands or collections that suppliers put on the market. The modulation of the fee should take into account the producers’/brands’ average usage phase.

The brands that are not found in the waste streams will be exempt from paying a fee. This may be because the products are perceived as so valuable by consumers that they remain in their possession. Differentiations based on clothing categories should, however, be included as some garment types are expected to have longer use phases than others, e.g, a coat versus a T-shirt.

Reuse and disposal phase

When more textiles are to be collected for reuse and recycling, and more is to be done in Europe rather than in the Global South, the costs of these processes will increase. If more is to be utilised at a higher level in the waste hierarchy, it will also cost more. Much of what is not reused today could be reused if the clothes were renewed, i.e. repaired, washed or stains were removed, which in turn captures the reuse value of these products but at the same time carries a cost. These activities and related business models are currently underfinanced, and they lack profitability due to the associated high costs of manual labour and the overload of big volumes of low-priced and low-quality fast fashion items with no or limited reuse value.  At the same time, certain textiles have a high value and can ensure a profit for collectors (e.g., resell business models where ca 5-10% of high-quality garments are sold on online platforms). It is important that all reusable textiles are given the opportunity to have longer lifespans, so if the EU is to aim to increase the reuse of textiles, preparation for reuse and repair activities must be financially supported by the EPR.

The same will apply to various forms of recycling: different products have different recycling costs. Some can be easily recycled; other textiles will not be recyclable at all or only if cost-intensive measures are first taken. As for the use phase, we, therefore, propose an average per brand based on how much the waste management costs. Those with a high reuse value and low cost of recycling will receive a lower fee, possibly an exemption in the end.

The modulation of the fee will thus consist of a combination of how long clothing from the brand is used on average and how costly better waste treatment is. Both evaluations can be made based on picking analyses that are repeated at regular intervals so that new brands, or improvements by already existing brands, can be captured. These analyses will also ensure increased knowledge about textile consumption and textile waste and will be important for statistics, research and regulation in the textile area. We have called this way of modulating the fee in an EPR system Targeted Producer Responsibility (TPR), which is described in ScienceNorway.no.

Production and marketing

The way EPR is usually conceived, the total tonnage of products placed on the market by an individual producer forms the starting point for the fee. But the quantities can also be used in the modulation of the environmental fee. It is possible to let those manufacturers who have many collections, a short timespan in-store for each individual product and also sell large volumes, incur a higher fee, which is then multiplied by the weight of what they place on the market. Proposals for such a fee modulation have been made by several Norwegian environmental organisations and can easily be combined with a TPR. It is also possible to use other parameters in the modulation, such as the proportion sold with reduced prices (the percentage that goes on sale), the proportion of returned goods, unsold goods, etc.

To summarise our proposal:

  • The EU has a golden opportunity to ensure a systemic change for the better of its citizens and the environment.
  • If we are to achieve the goal of reducing environmental impacts from textile production the quantities must be reduced. Less clothing is the prerequisite for each garment to be used longer, in line with the principles of the waste hierarchy and circular economy.
  • The measures proposed in the EU’s textile strategy (PEF; the Eco-design Directive and EPR) all focus on the product and its design, and thus not on the systemic changes. EPR on textiles can, if desired, be designed so that it changes the business models of fast fashion by making it less profitable, and those clothes that are used little and cost a lot to be reused and recycled also become unprofitable to put on the market.

The above concerns and suggestions were a selection of many, and we are aware that a successful EPR agenda in the EU will include many more elements and key areas for coherent consideration.

Thank you for your time and attention.

Review of clothing disposal reasons

Lisbeth Løvbak Berg on 19. October 2022

Authors: Kirsi Laitala and Ingun Grimstad Klepp, SIFO

Abstract

Garment lifetimes and longer serviceable life play important roles in discussions about the sustainability of clothing consumption.

A compilation of the research on clothing disposal motivations shows that there are three main reasons for disposal:

  1. Intrinsic quality (37%): Wear and tear-related issues such as shrinkage, tears and holes, fading of colour, broken zippers and loss of technical functions such as waterproofness.
  2. Fit (28%): Garments that do not fit either because the user has changed size, or the garment did not fit well to start with (for example due to unsuitable grading, insufficient wear ease or wrong size).
  3. Perceived value (35%): reasons where the consumer no longer wants the garment because it is outdated or out of fashion, or no longer is needed or wanted, or is not valued, for example when there is a lack of space in the wardrobe.

This shows that almost two-thirds of garments are discarded for reasons other than physical durability. Poor fit/design together with lack of perceived value by the owner are responsible for the majority of clothing disposals.

Physical strength is one of the several factors that are important if the lifetime of clothing is to be increased. However, it does not help to make clothes stronger if they are not going to be used longer anyway; this will just contribute to increased environmental impacts from the production and disposal phases. We do not need disposable products” that last for centuries. To work with reducing the environmental impacts of clothing consumption, it is important to optimize the match between strength, value and fit. This has the potential to reduce overproduction. Optimizing clothing lifespans will ensure the best possible utilization of the materials in line with the intentions of the circular economy.

Introduction

Garment lifetimes and longer serviceable life play important roles in discussions about the sustainability of clothing consumption.

Here we present the empirical findings summarized from the research that exists around clothing disposal. The review was originally conducted for the work with the development of durability criteria for Product Environmental Footprint Category Rules (PEFCR) for apparel and footwear. We believe this can be useful information for companies working to improve their products, and debate about clothing sustainability including the understanding of PEF.

We would like to thank Roy Kettlewell and Angus Ireland for their cooperation.

Method

The review includes empirical quantitative studies on clothing disposal reasons. The studies use varying methods, where online surveys are the most commonly used, but also two physical wardrobe studies are included. The way disposal reasons are studied varies as well. Many surveys ask for general, most common disposal reasons, while wardrobe studies and a few of the surveys focus on specific garments that the informants have disposed of. One of the online wardrobe surveys also asks for anticipated disposal reasons for specific garments instead of past behavior. All of the studies have been conducted between 1987 and 2020. The review excluded any studies that did not focus on disposal reasons or did not report results in a quantitative manner. In addition, it excludes a few lower-quality studies with methodological issues. In total 17 studies that fulfil the inclusion criteria were found.

Results

The review shows that clothing is discarded for many reasons. Table 1 summarizes the results and gives some information about the study sample such as where it was conducted and the number of respondents, as well as the main method that was used. Although there are differences between the surveys, they show a common feature. The results on disposal reasons could be placed in three main categories that were found in all reviewed studies: 1) intrinsic quality, 2) fit, and 3) perceived value, and an additional category for 4) other or unknown reasons. The categories include the following disposal reasons:

  1. Intrinsic quality: Wear and tear-related issues such as shrinkage, tears and holes, fading of colour, broken zippers and loss of technical functions such as waterproofness.
  2. Fit: Garments that do not fit either because the user has changed size, or the garment did not fit well to start with (for example due to unsuitable grading, insufficient wear ease or wrong size).
  3. Perceived value: reasons where the consumer no longer wants the garment because it is outdated or out of fashion, or no longer is needed or wanted, or is not valued, for example when there is a lack of space in the wardrobe.

Conclusion

A compilation of the research on clothing disposal motivations shows that there are three main reasons for disposal. Intrinsic quality, that is wear and tear and other physical changes of garments is the dominating disposal reason (37%), followed by lack of perceived value (35%) and poor fit (28%). This shows that almost two-thirds of garments are discarded for reasons other than physical durability. Poor fit/design together with lack of perceived value by the owner are responsible for the majority of clothing disposals.

Physical strength is one of the several factors that are important if the lifetime of clothing is to be increased. However, it does not help to make clothes stronger if they are not going to be used longer anyways, this will just contribute to increased environmental impacts from the production and disposal phases. We do not need “disposable products” that last for centuries. To work with reducing the environmental impacts of clothing consumption, it is important to optimize the match between strength, value and fit. Optimizing clothing lifespans will ensure the best possible utilization of the materials in line with the intentions of the circular economy.

Deep diving into wardrobes provides important knowledge on clothes and their environmental impact

Lisbeth Løvbak Berg on 8. September 2022

Authors: Vilde Haugrønning, Ingun Grimstad Klepp and Anna Schytte Sigaard

Norway leads the way in methods for studying the use of clothing. This is knowledge that is important in sustainability studies of apparel.

How many clothes are there in our wardrobes? What is used a lot and what do you seldom wear, and why? Which clothes have the largest environmental footprint? What causes clothes to be cared for and repaired?

There are many unanswered questions when the desire is to understand the connection between the consumption of clothing, and climate and environmental impacts. We need to understand why someone has a wardrobe full of clothes and still nothing to wear. To answer these questions, methods that can reconcile the concrete material with the way we use, buy, repair, launder, choose and not least throw away clothes, are required.

The method called “wardrobe studies” is very central in studies of clothing’s environmental impact. Consumption Research Norway (SIFO) at Oslo Metropolitan University has been at the centre of the development of these methods for 23 years. Today, the method is included in research, teaching, product development and design worldwide.

Research in people’s homes

The method involves the researcher and informant going through the informant’s wardrobe piece by piece, together. In some studies, the entire wardrobe is reviewed and in others, selected parts such as passive clothes, leisure and sports clothes, or favourite clothes are specifically studied. When the clothes are reviewed, the researcher asks the same questions for each garment. This gives us opportunities to analyze differences in the way different garments are used.

The method is time-consuming but provides detailed and reliable knowledge. Ideally, we do this at the informants’ homes and thus also gain knowledge about details around the organisation, storage, laundering and care of the clothes.

Clothes are complex

Wardrobe studies are particularly suitable for studying practices that we often take for granted. The practices are important to understand in order to gain better knowledge of consumption patterns, and thus how they can be changed in a more sustainable direction. The special feature of the method is that the clothes are at the centre of the analysis.

Clothes are very complex materially, socially and culturally. They are made from most types of materials, from animals and plants, including metal and chemicals and increasingly plastic. They are used to camouflage the body, keep it warm, decorate, protect and show belonging to cultures, groups, places and positions in society. Clothes are important for self-respect, security and social participation.

In order to embrace so many different aspects and see them in context, methods are required which have the capacity to connect the actual material with the practices and their many different meanings, both for the individual and society.

What properties do the clothes have?

Wardrobe studies lead to more knowledge about the use of clothes. This stands in contrast to studies that are concerned with clothes related to fashion, often understood as the novelty value of the clothes. In such studies, some things are often excluded, namely the material properties of the clothes, as well as all the nuances in the relationship between the wearer of the clothes and the clothes themselves, and the interplay between the clothes in the wardrobe.

After conversations with people about clothes over several decades, we have rarely heard informants say that fashion is important to them, and it is much more common to say the opposite. Fashion is an aspect of our clothes, but for most people, there are completely different reasons for both what you buy and what you wear. Fashion can make it difficult to find something you like in the store, such as the colour you think suits you, or a shape that is perceived as flattering.

Few know how many clothes they own

To capture the material in wardrobe studies, various techniques are used to obtain information about each individual garment such as photos, interviews, registrations and technical analyses. This gives the advantage that the information becomes concrete and tied to both the material and social aspects, and thus not so dependent on words alone.

Clothing habits, like other parts of our daily lives, are something we don’t usually think about. Therefore, they are also difficult to put into words in a conversation or interview situation. It is easier to describe the clothes and how they are used when we talk about specific garments. It will then be possible for us researchers later to see the relationship between the clothes and the wearer, and pursue what lies behind the words.

Very few know the average age of their own wardrobe or how many clothes they actually have. We ask people about what they know and have a relationship with, but compile the information ourselves with national or global averages, or qualitatively based interpretations.

Knowledge to inform policy

Today, SIFO has several ongoing research projects with wardrobe studies: CHANGE, Wasted Textiles and Belong, all funded by the Research Council of Norway. Here the wardrobe studies are used to study how we use clothes for different occasions and the importance of variation in clothing habits, how we can reduce the amount of textiles and specifically synthetic textiles, and the importance of clothes for belonging.

In all projects, wardrobe studies contribute to important knowledge about the importance of clothing and textiles in our everyday lives. This knowledge is crucial to developing policies capable of drastically reducing climate and environmental impact, and at the same time ensuring everyone in the population has access to good clothing.

An important challenge in the work with clothing and the environment has long been very inadequate life cycle analyses (LCAs). Without knowledge of lifespan, disposable products are compared to clothes that are worn 500 times or more.

No one would argue that such a use of LCAs is correct, but going from this point of departure to finding methods to include lifespan in LCAs of environmental impact, is quite a challenge. SIFO has further developed the wardrobe studies method in a quantitative direction in order to obtain knowledge about global clothing habits suitable for such analyses.

Consumption is important

In these studies, we work with detailed information on 53,461 garments which gives the opportunity to ask questions about, for example, differences between different types of garments, fibres or what the clothes are used for. This is very relevant when the EU is now developing a new labelling scheme, the Product Environmental Footprint (PEF), which will include textiles. SIFO, therefore, contributes to the development of the rules specific to clothing in this labelling scheme. There, as in many other contexts, it is difficult to get the impression that consumption is important.

The work with wardrobe studies shows that in research it is not only important to develop good questions, but that the methods must also be adapted so that we researchers are able to deliver the knowledge that society needs. Climate and environmental problems cannot be solved without knowledge of people, society, politics and regulation. It is urgent to take the fact that we humans have created the problems seriously, but that we can also solve them. For that, we need more knowledge about ourselves and our habits and the way we use products that burden the climate and the environment a lot, such as apparel.

Delivering EU Environmental Policy Through Fair Comparisons of Natural and Synthetic Fibre Textiles in PEF

Summary

Sustainability has become a priority objective for the European Union (EU). It is a key driver for policy development through the global leadership role the EU has taken in addressing climate change, decoupling economic growth from resource use, and the sustainable use of
resources. The global supply of textiles has been recognized by the EU as a major source of emissions and resource use; the sector has become increasingly reliant on fossil feedstocks to supply synthetic fibres, and the textile industry has been roundly criticised for unsustainable and non-circular consumption patterns.


The Product Environmental Footprint (PEF) system – which assesses a product’s environmental impact and provides consumers with information on that impact – has the potential to be paramount in directing the textile sector towards a sustainable system of production and consumption. However, the PEF system has not been designed to deliver the EU’s strategies and, without amendment, its application to the textiles sector risks undermining the EU’s laudable intent. The PEF system is designed to facilitate like-with-like comparisons, but assessment of textiles made from natural and synthetic fibres are not yet comparable because the impacts of forming natural fibres are fully accounted for, but omitted for fossil fuels. The single biggest sustainability issue for the textile industry is the growth in synthetic fibre production and the causally related rise in fast fashion. A PEF-derived comparison will not challenge the over-consumption of resources, and risks legitimising unsustainable consumption with an EU-backed green claim.


These limitations present a significant challenge to the delivery of both EU strategy and the PEF goal of providing fair comparisons of products based on their environmental credentials.


In combination, the characteristics of the textiles category, together with the limitations of PEF methodology, provide a strong argument for not comparing textiles made from renewable and non-renewable raw materials. However, achieving the EU Green Deal and circular economy objectives mandates a pragmatic approach; hence our analysis recommends methodological improvements to deliver EU environmental policy through fair comparisons of natural and synthetic fibre textiles in PEF. Addressing these limitations now will avoid
the same problems arising when PEF is applied to other product categories that compare renewable and non-renewable raw materials, such as furniture and fuel.

Abstract

Wool of mountain sheep, treated nowadays as a waste or troublesome byproduct of sheep husbandry, was used for the production of sound-absorbing materials. Felts of two different thicknesses were produced from loose fibres. Additionally, two types of yarn,ring-spun and core rug, were obtained. The yarns were used for the production of tufted fabric with cut and loop piles. During the examinations, basic parameters of the obtained materials were determined. Then, according to standard procedure with the use of impedance tube, the sound absorption coefficient was measured, and the noise reduction coefficient (NRC) was calculated. It was revealed that felt produced from coarse wool exhibits high porosity, and its sound-absorbing capacity is strongly related to the felt thickness. For thicker felt the NRC achieved0.4, which is comparable with the NRC of commercial ceiling tiles. It was shown that the crucial parameter influencing the sound absorption of the tufted fabrics was the pile height. For both types of yarns, when the height of the pile was increased from 12 to 16 mm, the NRC increased from 0.4 to 0.42. The manufactured materials made from local wool possess good absorption capacity, similar to commercial products usually made from more expensive wool types. The materials look nice and can be used for noise reduction as inner acoustic screens, panels, or carpets.
