KRUS final report: Enhancing local value chains in Norway

  • av

From its initiation in 2015 to the end in 2019, KRUS had two goals: to improve the market for and the value of Norwegian wool, and survey the opportunities for local production in a move towards a goal of sustainability in the fashion sector. On a larger scale, KRUS has looked at how we can re-establish an understanding of the connection between the raw material and the finished product within the textile industry and among consumers. It is critical to understand this connection, both to ensure quality products and to reach the market potential for Norwegian wool.

Microfibres from apparel and home textiles: Prospects for including microplastics in environmental sustainability assessment

  • av

Textiles release fibres to the environment during production, use, and at end-of-life disposal. Approximately two-thirds of all textile items are now synthetic, dominated by petroleum-based organic polymers such as polyester,polyamide and acrylic. Plastic microfibres (b5 mm) and nanofibres (b100 nm) have been identified in ecosystems in all regions of the globe and have been estimated to comprise up to 35% of primary microplastics in marine environments, a major proportion of microplastics on coastal shorelines and to persist for decades in soils treated with sludge from waste water treatment plants.
In this paper we present a critical review of factors affecting the release from fabrics of microfibres, and of the risks for impacts on ecological systems and potentially on human health. This review is used as a basis for exploring the potential to include a metric for microplastic pollution in tools that have been developed to quantify the environmental performance of apparel and home textiles. We conclude that the simple metric of mass or number of microfibres released combined with data on their persistence in the environment, could provide a useful interim mid-point indicator in sustainability assessment tools to support monitoring and mitigation strategies for microplastic pollution. Identified priority research areas include: (1) Standardised analytical methods for textile microfibres and nanofibres; (2) Ecotoxicological studies using environmentally realistic concentrations; (3) Studies tracking the fate of microplastics in complex food webs; and (4) Refined indicators for microfibre impacts in apparel and home textile sustainability assessment tools.

Does Use Matter? Comparison of Environmental Impacts of Clothing Based on Fiber Type

  • av

Several tools have been developed to compare the environmental impact of textiles. The most widely used are Higg Materials Sustainability Index (MSI) and MADE-BY Fiber Benchmark. They use data from production to evaluate the environmental impacts of textiles differentiated by fiber type. The use phase is excluded from both tools. This article discusses whether there is evidence that the use of textiles differs systematically between different fiber types and examines the consequences of comparing the environmental impacts of clothing based on differences in production of fibers alone without including differences in their use.

The empirical material in this paper is based on analysis of rating tools and a literature review on clothing use. It shows that fiber content contributes to the way consumers take care of and use their clothing. When use is omitted, major environmental problems associated with this stage, such as spread of microplastics, are also excluded. This one-sided focus on material production impacts also excludes the importance of product lifespans, quality, and functionality. The consequence is that short-lived disposable products are equated with durable products. Comparing dissimilar garments will not help consumers to make choices that will reduce the environmental burden of clothing. We need an informed discussion on how to use all materials in the most environmentally sustainable way possible.

Nisseluelandet—The Impact of Local Clothes for the Survival of a Textile Industry in Norway

  • av

The article discusses the importance of local clothing for the survival of the Norwegian textile industry. It draws upon stakeholder interviews, as well as desktop research. Local clothes are discussed as they are understood by consumers, as knitted sweaters, bunads (Norwegian national costumes), and home-made clothing. The review shows how these products, and especially the materials used in their production, have been crucial for the continued existence of the Norwegian textile industry. We argue that the concept “local clothes” can contribute to showcasing resources outside the global “fast fashion” manufacturing system.

Use phase of apparel: A Literature review for Life Cycle Assessment with focus on wool.

  • av

This report presents a literature review of clothing use phase. The purpose is to support improved methodological development for accounting for the use phase in Life Cycle Assessment (LCA) of apparel. All relevant textile fibres are included in the review. However, the main focus is on wool. We ask whether the use of wool has different environmental impacts than clothes in other fibres. The report builds on a review of literature from the past 20 years. The review showed that clothing made from different materials are used, and reused in different ways. Wool is washed differently as it has about ten degrees lower washing temperature than the average laundry in Europe. Wool is also more likely to be either dry-cleaned or washed by hand than other textiles. Moreover, when dried, it is less likely to be tumble-dried.

Global laundering practices: Alternatives to machine washing

  • av

This article discusses laundering practices around the world including alternative methods such as washing by hand, airing, steaming, and dry-cleaning. These methods, which have received little attention in research, are often more suited toproducts made of wool, silk or other materials able to be cleaned using gentler techniques than more commonly used fibers such as cotton and synthetics. The material is based on extensive literature review from the past 20 years and reanalysis of previously unpublished survey data.The results show that washing by hand is common and that is the main laundering method in most rural areas of developing countries, but also significant for smaller portion of laundry in developed countries. Dry cleaning is less common, and mainly used for specific clothing items. Simple method such as airing can reduce the washing frequency, and thus reduce the environmental impacts resulting from the cleaning of clothes.

Opprinnelsesmerking av norsk ull

  • av

Hensikten med denne rapporten er å undersøke mulighetene for en opprinnelsesmerking av norsk ull. Et slikt merke kan bidra til økt bevissthet og oppmerksomhet om norsk ull både blant produsenter og forbrukere, og dermed styrke produksjon og salg av lokal ull. Rapporten diskuterer en rekke argumenter for en merkeordning. Blant annet at et offisielt merke kan være et hjelpemiddel mot en til dels uryddig markedsføring av ull som vi ser i dag. Dessuten kan det fremme ulike kvaliteter ved norsk ull.
Rapporten bygger på ulike data inkludert intervjuer med aktører i verdikjeden og forbrukerundersøkelser. Erfaringer med merkeordninger fra andre land samt ulike mat-og miljømerkeordninger er også diskutert. Rapporten kan fungere som et kunnskapsgrunnlag for en eventuell etablering av en merkeordning, og den utreder ulike alternative ordninger, men uten å ta stilling til hvordan en merkeordning faktisk bør organiseres.

What’s the Problem? Odor-control and the Smell of Sweat in Sportswear

  • av

Sport and fitness are increasing in popularity, and so is awareness of body odor. Both are aspects people wish to gain control over, as promised by the marketing of sportswear with odor-controlling properties. This article discusses how the heightened awareness of body odor has developed, and how unpleasant odor varies between textiles made of different materials. A sensory analysis by a consumer panel was used to evaluate the odor intensity of 13 different fabric samples taken mainly from sportswear.

The so-called odor-control textiles smelled less intense than similar polyester samples without such treatment. Wool and cotton smelled significantly less intense than both odor-control and polyester when the samples were sweaty or aired. After washing, the odor-control textiles had a level of odor intensity that was in between that of the cotton and woolen samples. The odor-control treatment reduced the smell, but not enough to make a difference on laundering frequency, and the textiles smelled still more strongly than wool.

Wool as an Heirloom: How Natural Fibres Can Reinvent Value in Terms of Money, Life-Span and Love

  • av

This paper addresses a main challenge for natural fibres; falling prices and increased focus on quantity versus quality. This is a challenge not only related to economic issues and profit, but is also unsustainable in an environmental perspective and in light of the challenges the textile sector and the world face. The paper uses wool as an example and in a surprising approach links the history and century-old traditions of natural fibers to an environmental thinking which supplements the traditional thinking around circular economy and LCA. Fabrics with a long life are the ones that have the lowest environmental impact (Fletcher and Tham2015; Laitala2014). Longevity or lifespan is a complex phenomenon in which both technical and social, or aesthetic aspects, are intertwined.
