    Integration of Screen Printed Piezoelectric Sensors for Force Impact Sensing in Smart Multifunctional Glass Applications2022Inngår i: Advanced Engineering Materials, ISSN 1438-1656, E-ISSN 1527-2648, Vol. 24, nr 11, artikkel-id 2200399Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Screen printed piezoelectric polyvinylidene fluoride?trifluoro ethylene (PVDF?TrFE)-based sensors laminated between glass panes in the temperature range 80?110?°C are presented. No degradation of the piezoelectric signals is observed for the sensors laminated at 110?°C, despite approaching the Curie temperature of the piezoelectric material. The piezoelectric sensors, here monitoring force impact in smart glass applications, are characterized by using a calibrated impact hammer system and standardized impact situations. Stand-alone piezoelectric sensors and piezoelectric sensors integrated on poly(methyl methacrylate) are also evaluated. The piezoelectric constants obtained from the measurements of the nonintegrated piezoelectric sensors are in good agreement with the literature. The piezoelectric sensor response is measured by using either physical electrical contacts between the piezoelectric sensors and the readout electronics, or wirelessly via both noncontact capacitive coupling and Bluetooth low-energy radio link. The developed sensor concept is finally demonstrated in smart window prototypes, in which integrated piezoelectric sensors are used to detect break-in attempts. Additionally, each prototype includes an electrochromic film to control the light transmittance of the window, a screen printed electrochromic display for status indications and wireless communication with an external server, and a holistic approach of hybrid printed electronic systems targeting smart multifunctional glass applications.

    Mapping and Evaluation of some Restricted Chemical Substances in Recycled Plastics Originating from ELV and WEEE Collected in Europe2019Rapport (Annet vitenskapelig)
    Abstract [en]

    Recycling of plastics is a critical step toward the realisation of a sustainable society. Plastic is a fitting material to recycle, as it often can easily be melted and formed into new products. Plastic recycling is therefore an easy process with pure plastics, however, most of the plastics that are recycled today are not pure and contain additives and/or impurities. Some of these additives can be hazardous substances that could be harmful for both humans and the environment. It is therefore important that these hazardous substances are not recycled and transferred into new products. To ensure a safe use of plastics, these substances are today regulated in new products, but old products could still contain these substances (legacy chemicals). To comply with legislation it is therefore critical that these substances are removed during the recycling process. There are however many hazardous substances that are yet not regulated, which may also be present in products and therefore recycled material. 

    Waste Electronic and Electrical Equipment (WEEE) and End-of-Life Vehicles (ELV) are two of the materials streams that contains a high amount of legacy chemicals. These streams have been associated with spreading legacy chemicals after recycling. In several reports WEEE plastics have been identified as the source of brominated flame retardants (BRF) found in toys and everyday items. According to the EU regulation the use of certain BFRs is not permitted in new products or articles above a certain value. Recyclers and resellers of the recycled plastic often specified that the products should not be used in toys, medical equipment of food contact application, yet BFRs from WEEE can still be found in these products. This could mean that either producers that use recycled material in new products do not follow the recommendations from the recyclers, or that the recycled material does not fulfil the regulations. Another possibility for the findings of legacy chemicals in these items could be a meagre follow-up on imported plastics.

    In this study the Research Institutes of Sweden (RISE) has, on behalf of the Swedish Environmental Protection Agency (Naturvårdsverket), investigated the content of legacy chemicals in recycled plastics that have been processed in a recycling facility. The plastics originated from WEEE and ELV and have been gathered from recyclers across Europe. A number of different legacy chemicals were investigated, both inorganic (Cd, Pb, Hg) and organic substances (flame retardants and plasticisers). To simulate a real case scenario and to get better measurement accuracy, all samples were injection moulded. The analysis of the samples was performed using X-ray fluorescence spectrometry (XRF), Inductively coupled plasma (ICP) and Gas chromatography with a Mass spectrometer (GC-MS). All the processing and analysis (except for SCCP/MCCP)) were done by RISE which gives good control over the analysis process, which are important when interpreting the results. In total 54 samples of PE, PP, ABS and PS, were gathered and tested. It was found that all but two samples contained legacy chemicals below the regulated values. The two samples that did not meet the legal limit had a HBCDD content above 100 ppm. All the tested materials contained detectable amounts of bromine, and 15 samples contained detectable amounts of regulated BFRs. None of the detected regulated BRFs were above 186 ppm.  Most of the materials also contained detectable amounts of cadmium and lead.

    Polymer Core-Polymer Shell Particle Formation Enabled by Ultralow Interfacial Tension Via Internal Phase Separation: Morphology Prediction Using the Van Oss Formalism2018Inngår i: Colloid and Interface Science Communications, ISSN 2215-0382, Vol. 25, s. 36-40Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The internal phase separation technique is a versatile method for liquid core-polymer shell formation, yet limited to very hydrophobic core materials and actives. The use of polymeric cores instead circumvents this restriction due to the absent mixing entropy for binary polymer mixtures which allows the polymeric core (and the active) to approach the polarity of the shell. Polystyrene core-shell and janus particles were formulated using polymethylmethacrylate, poly(lactic acid), poly(lactic acid-co-glycolic acid), poly(ε-caprolactone) or cellulose triacetate as shell-forming polymers. The morphology and the partitioning was experimentally determined by selectively staining the core and the shell with β-carotene and methylene blue respectively. In addition, the van Oss formalism was introduced to theoretically predict the thermodynamic equilibrium morphology. As elucidated using the theoretical predictions as well as experimental optical tensiometry, it was found that the driving force for core-shell morphology is, in contrast to liquid core-polymer shell particles, a low core-shell interfacial tension.

    Systematic evaluation of bromine-free flame-retardant systems in acrylonitrile-butadiene-styrene2022Inngår i: Journal of Applied Polymer Science, ISSN 0021-8995, E-ISSN 1097-4628, Vol. 139, nr 13, artikkel-id 51861Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A systematic investigation of phosphorus-based flame-retardant (PFR) systems in acrylonitrile-butadiene-styrene (ABS) is presented. The effect of various PFRs, combinations thereof and influence of different synergists is studied in terms of fire and mechanical performance, as well as toxicity of resulting ABS. Sustainable flame-retardant systems with a promising effect on the fire-retardant properties of ABS are identified: A combination of aluminum diethylphosphinate and ammonium polyphosphate is shown to exhibit superior flame-retardant properties in ABS compared to other studied PFRs and PFR combinations. Among a variety of studied potential synergists for this system, a grade of expandable graphite with a high-initiation temperature and a molybdenum-based smoke suppressant show the most promising effect, leading to a significant reduction of the peak heat release rate as well as the smoke production rate. Compared to current state-of-the-art brominated flame-retardant for ABS, the identified flame-retardant systems reduce the maximum smoke production rate by 70% and the peak heat release rate by 40%. However, a significant reduction of the impact performance of the resulting ABS is identified, which requires further investigation.

    Chemical Recycling of a Textile Blend from Polyester and Viscose, Part II: Mechanism and Reactivity during Alkaline Hydrolysis of Textile Polyester2022Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 14, nr 11, artikkel-id 6911Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Chemical recycling of textiles holds the potential to yield materials of equal quality and value as products from virgin feedstock. Selective depolymerization of textile polyester (PET) from regenerated cellulose/PET blends, by means of alkaline hydrolysis, renders the monomers of PET while cellulose remains in fiber form. Here, we present the mechanism and reactivity of textile PET during alkaline hydrolysis. Part I of this article series focuses on the cellulose part and a possible industrialization of such a process. The kinetics and reaction mechanism for alkaline hydrolysis of polyester packaging materials or virgin bulk polyester are well described in the scientific literature; however, information on depolymerization of PET from textiles is sparse. We find that the reaction rate of hydrolysis is not affected by disintegrating the fabric to increase its surface area. We ascribe this to the yarn structure, where texturing and a low density assures a high accessibility even without disintegration. The reaction, similar to bulk polyester, is shown to be surface specific and proceeds via endwise peeling. Finally, we show that the reaction product terephthalic acid is pure and obtained in high yields. © 2022 by the authors.

    Fully Screen-Printed Stretchable Organic Electrochemical Transistors2023Inngår i: Advanced Materials Technologies, E-ISSN 2365-709XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Stretchable organic electrochemical transistors (OECTs) are promising for wearable applications within biosensing, bio-signal recording, and addressing circuitry. Efficient large-scale fabrication of OECTs can be performed with printing methods but to date there are no reports on high-performance fully printed stretchable OECTs. Herein, this challenge is addressed by developing fully screen-printed stretchable OECTs based on an architecture that minimizes electrochemical side reactions and improves long-term stability. Fabrication of the OECTs is enabled by in-house development of three stretchable functional screen-printing inks and related printing processes. The stretchable OECTs show good characteristics in terms of transfer curves, output characteristics, and transient response up to 100% static strain and 500 strain cycles at 25% and 50% strain. The strain insensitivity of the OECTs can be further improved by strain conditioning, resulting in stable performance up to 50% strain. Finally, an electrochromic smart pixel is demonstrated by connecting a stretchable OECT to a stretchable electrochromic display. It is believed that the development of screen-printed stretchable electrochemical devices, and OECTs in particular, will pave the way for their use in wearable applications and commercial products. © 2023 The Authors.

    Nanocellulose based carbon ink and its application in electrochromic displays and supercapacitors2021Inngår i: Flexible and Printed Electronics, ISSN 2058-8585, Vol. 6, nr 4, artikkel-id 045011Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Conventional electronics have been highlighted as a very unsustainable technology; hazardous wastes are produced both during their manufacturing but also, due to their limited recyclability, during their end of life cycle (e.g. disposal in landfill). In recent years additive manufacturing processes (i.e. screen printing) have attracted significant interest as a more sustainable approach to electronic manufacturing (printed electronics). Despite the field of printed electronics addressing some of the issues related to the manufacturing of electronics, many components and inks are still considered hazardous to the environment and are difficult to recycle. Here we present the development of a low environmental impact carbon ink based on a non-hazardous solvent and a cellulosic matrix (nanocellulose) and its implementation in electrochromic displays (ECDs) and supercapacitors. As part of the reported work, a different protocol for mixing carbon and cellulose nanofibrils (rotation mixing and high shear force mixing), nanocellulose of different grades and different carbon: nanocellulose ratios were investigated and optimized. The rheology profiles of the different inks showed good shear thinning properties, demonstrating their suitability for screen-printing technology. The printability of the developed inks was excellent and in line with those of reference commercial carbon inks. Despite the lower electrical conductivity (400 S m-1 for the developed carbon ink compared to 1000 S m-1 for the commercial inks), which may be explained by their difference in composition (carbon content, density and carbon derived nature) compared to the commercial carbon, the developed ink functioned adequately as the counter electrode in all screen-printed ECDs and even allowed for improved supercapacitors compared to those utilizing commercial carbon inks. In this sense, the supercapacitors incorporating the developed carbon ink in the current collector layer had an average capacitance = 97.4 mF cm-2 compared to the commercial carbon ink average capacitance = 61.6 mF cm-2. The ink development reported herein provides a step towards more sustainable printed green electronics. © 2021 The Author(s).

    Transforming post-consumer cotton waste textiles into viscose staple fiber using hydrated zinc chloride2023Inngår i: Cellulose, ISSN 0969-0239, E-ISSN 1572-882XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Large amounts of cellulose-based waste textiles are generated every year, yet little is done to recycle this waste. Alternatives such as fiber-to-fiber recycling, where a significant part of the value of the waste textiles is recovered, are attractive possibilities. In this study, we have investigated the viability of using hydrated zinc chloride (ZnCl2·4H2O) as a solvent and swelling agent to convert cotton waste textiles (the most abundant cellulose-based waste textile) into a dissolving pulp that can be used as raw material for the production and spinning of viscose fibers. The solvent produced an accessible dissolving pulp and exhibited excellent recyclability, maintaining good dissolving power even after repeated recycling. The dissolving pulp was subsequently used to produce viscose dope, a spinning solution which was spun and cut into viscose staple fibers. The viscose dope exhibited good properties (moderate filter clogging value and gamma number), and the resulting staple fibers were strong and of good quality (high linear density, elongation, and tenacity). These results illustrate the potential of using hydrated zinc chloride for the production of viscose grade dissolving pulp from cotton waste textiles.

    Structural Concept of Novel RPC Sandwich Façade Elements with GFRP Connectors2016Inngår i: IABSE Congress Stockholm 2016: Challenges in Design and Construction of an Innovative and Sustainable Built Environment. Report, IABSE c/o ETH Hönggerberg , 2016, s. 2164-2171Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The SESBE research project aims to develop novel smart sandwich façade elements with high insulating capabilities while providing a reduced thickness in conjunction with superior mechanical and durability properties. The present paper mainly focuses on the verification of the mechanical performance of the glass fibre reinforced polymer (GFRP) connectors in the façade element composed of reactive powder concrete (RPC) panels with foam concrete insulation between them. Because of the reduced thickness of the large façade elements, the performance of the connectors is critical for the entire structural concept. A description of structural performance and results based on experimental methods and finite element (FE) analysis are presented.

    Development of Circularly Recyclable Low Melting Temperature Bicomponent Fibers toward a Sustainable Nonwoven Application2021Inngår i: ACS Sustainable Chemistry and Engineering, E-ISSN 2168-0485, Vol. 9, nr 49, s. 16778-16785Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Sustainable low melting temperature bicomponent polyester fibers that can be circularly recycled were developed. The potentially biobased poly(hexamethylene terephthalate) (PHT), acting as the low melting temperature sheath material in the designed bicomponent fibers, was synthesized in a pilot scale. The obtained PHT with an intrinsic viscosity of 0.47 dL/g showed suitable processability when it was processed together with a poly(butylene terephthalate) (PBT) core in a melt-spinning process of bicomponent fibers. Compared with the commercial low melting temperature terephthalate-isophthalate copolyester LMP-160, PHT showed superior mechanical properties according to DMA analysis. The low melting temperature bicomponent fibers with a ratio of the PBT core and PHT sheath at 70:30 were produced smoothly at 290 °C in a pilot melt-spinning line. Preliminary chemical recycling investigations by methanolysis revealed that PHT/PBT bicomponent fibers were completely depolymerized within 2 h at 200 °C, yielding pure terephthalate, which could be conveniently separated and recycled. This indicated the feasibility of circular recycling, which will greatly improve the sustainability of nonwovens thermally bonded by these new bicomponent fibers. © 2021 The Authors.

    Återvinning av textilier: Hur säkerställer man giftfria flöden i relation till textilåtervinning2016Rapport (Annet vitenskapelig)
    Abstract [sv]

    Huvudsyftet med arbetet var att främja ökad återvinning av textilt spill utan ökad spridning av giftiga ämnen eller minskad kvalitet. Arbetet har till stor del utförts genom fallstudier men även genom myndighetsdialoger, underlag till myndigheter och företag samt initiering av nya relevanta forskningsstudier.Målet i arbetspaket 3 Textil var att ta fram ett kvalificerat underlag för ökad användning av giftfri återvunnen textilråvara genom att studera och beskriva kunskapsläget samt ta fram ny kunskap och driva en aktiv dialog med relevanta aktörer inom fyra fokusområden:1. Spårbarhet2. Minskning av spill3. Teknikutveckling för återvinning av textil4. Återvinning på den svenska marknadenMålet har väl uppfyllts och projektet har bidragit till ökad kunskap om möjligheter för ökad användning av giftfri återvunnen textilråvara. Framförallt har fallstudier genererat detaljerad förståelse för vilka specifika utmaningar som är kopplade till olika textila material och fiberslag.Arbetet har utförts i tät samverkan och dialog med parter från textilbranchen: Boob, Filippa K, Gudrun Sjöden, Fjällräven och WRSD, Swegmarks, Ragnsells, Re:Newcell, samt några av deras leverantörer och flera medlemmar i Kemikaliegruppen på Swerea IVF.Projektet visar att materialspecifik kunskap och teknik är det viktigaste steget mot ökad återvinning av industriella restprodukter. Detta är således en förutsättning för att den sekundära råvaran ska ha ett tillräckligt värde och ändamålsenlig kvalitet. Dessa specifika aspekter kommer att studeras vidare inom efterföljand

    Preparation of silica/polyelectrolyte complexes for textile strengthening applied to painting canvas restoration2017Inngår i: Colloids and Surfaces A: Physicochemical and Engineering Aspects, ISSN 09277757, Vol. 532, s. 420-427Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We here report three different approaches to prepare silica-polyelectrolyte complexes for mechanical strengthening of cotton fibers. In the first approach, polyvinylpyrrolidone (PVP) was used as a stabilizing polymer to delay the adsorption of a poly(quaternary ammonium) species, PQA (a copolymer of dimethylamine and epichlorohydrin), on the surface of silica. In the second approach cationic starch (CS), which is a branched polyelectrolyte, was used and the adsorption of CS resulted in formulations with good colloidal stability. The third approach was based on reduction of the charge density of silica to prevent PQA adsorption. Lowering the pH reduced the surface charge of the silica and enabled control of the adsorption. As a result, the aggregation was prevented and only a thin layer of polymer adsorbed. For all formulations a second polyelectrolyte, carboxymethyl cellulose (CMC) was subsequently adsorbed on the cationic polyelectrolyte layer. The silica/polyelectrolyte formulations were evaluated by dynamic light scattering (DLS). The obtained formulations were applied on model surfaces of degraded painting canvas. The performance of the silica particles coated either with one cationic polyelectrolyte and or with a layer of cationic polyelectrolyte followed by a layer of anionic polyelectrolyte were assessed by tensile testing and the morphology of the treated samples was investigated with SEM. The particles coated with a single cationic layer increased the maximum load at break by 29% at the cost of a reduction in strain. The particles coated with a double layer increased the maximum load to a lesser extent; however, higher values of strain were recorded. For all systems the mass uptake was limited to around 5 wt%.

    Energy harvesting textiles for a rainy day: woven piezoelectrics based on melt-spun PVDF microfibres with a conducting core2018Inngår i: npj Flexible Electronics, Vol. 2, artikkel-id 9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent advances in ubiquitous low-power electronics call for the development of light-weight and flexible energy sources. The textile format is highly attractive for unobtrusive harvesting of energy from e.g., biomechanical movements. Here, we report the manufacture and characterisation of fully textile piezoelectric generators that can operate under wet conditions. We use a weaving loom to realise textile bands with yarns of melt-spun piezoelectric microfibres, that consist of a conducting core surrounded by β-phase poly(vinylidene fluoride) (PVDF), in the warp direction. The core-sheath constitution of the piezoelectric microfibres results in a—for electronic textiles—unique architecture. The inner electrode is fully shielded from the outer electrode (made up of conducting yarns that are integrated in the weft direction) which prevents shorting under wet conditions. As a result, and in contrast to other energy harvesting textiles, we are able to demonstrate piezoelectric fabrics that do not only continue to function when in contact with water, but show enhanced performance. The piezoelectric bands generate an output of several volts at strains below one percent. We show that integration into the shoulder strap of a laptop case permits the continuous generation of four microwatts of power during a brisk walk. This promising performance, combined with the fact that our solution uses scalable materials and well-established industrial manufacturing methods, opens up the possibility to develop wearable electronics that are powered by piezoelectric textiles.

    Oilseed meal based plastics from plasticized, hot pressed crambe abyssinica and brassica carinata residuals2013Inngår i: Journal of the American Oil Chemists Society, ISSN 0003-021X, E-ISSN 1558-9331, nr 8, s. 1229-1237Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    With the increased use of plant oils as sustainable feedstocks, industrial oilseed meal from Crambe abyssinica (crambe) and Brassica carinata (carinata) can become a potential source for oilseed meal based plastics. In this study, crambe and carinata oilseed meal plastics were produced with 10-30 % glycerol and compression molding at 100-180 C. Size exclusion HPLC was used to relate tensile properties to changes in protein solubility and molecular weight distribution. By combining glycerol and thermal processing, increased flexibility has been observed compared to previous work on unplasticized oilseed meal. Tensile results varied from a brittle crambe based material (10 % glycerol, 130 C), Young's modulus 240 MPa, strain at maximum stress of 2 %, to a soft and flexible carinata based material (30 % glycerol, 100 C), Young's modulus 6.5 MPa, strain at maximum stress of 13 %. Strength and stiffness development with increasing molding temperature is in agreement with the protein profiles obtained. Thus, the highest mechanical parameters were obtained at the protein solubility minimum at 140 C. Higher temperatures caused protein degradation, increasing the level of low molecular weight extractable proteins. In carinata based materials the strain at maximum stress decreased as the protein aggregation developed. Results presented indicate that both crambe and carinata oilseed meal based materials can have their properties modulated through thermal treatment and the addition of plasticizers.

    Preparation and characterization of biobased thermoset polymers from renewable resources and their use in composites2017Inngår i: Handbook of Composites from Renewable Materials / [ed] Thakur, V.K.a, Thakur, M.K.b, Kessler, M.R.c, wiley , 2017, Vol. 1-8, s. 425-457Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    This chapter focuses on physicochemical and mechanical characterization of composites made from renewable materials. Most common renewable materials used in composites are natural fibers and polymers based on starch or vegetable oil. The extent of using renewable materials in biocomposites has increased during the past decade due to extensive research on cellulosic fibers and biobased polymers. Earlier, the research was focused on using the natural fibers as reinforcement in crude oil-based polymers such as polypropylene. Later, the emphasis shifted to increase the amount of renewable components in the biocomposites which led to the introduction of biobased resins in the composites. The properties of some biocomposites are today comparable to the properties for commercially available nonrenewable composites. Several plant biofibers have been used as reinforcement in biobased thermoplastics or thermosets to manufacture biocomposites. Material characterization is important to understand the performance of these composites under specific environment. Detailed discussion about the mechanical and physicochemical characterization is provided in this chapter. Physicochemical characterization includes chemical composition, density, viscosity, molecular weight, melting temperature, crystallinity, morphology, wettability, surface tension, water binding capacity, electrical conductivity, flammability, thermal stability, and swelling. Mechanical characterization includes tensile, flexural, impact, compressive, shear, toughness, hardness, brittleness, ductility, creep, fatigue, and dynamic mechanical analysis. © 2017 Scrivener Publishing LLC.

    New bio-based plastics from a non-edible plant oil side-stream for film extrusion2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Renewable sourced PET, PA, PE, starch blends, etc, are fastly growing due to the processability and final performance, that is similar to their petroleum derived options. A bit in the shadow of the development of these plastics, development is ongoing on another group of plastics, made directly of the side-streams of agricultural products: oil plant residues and proteins. They can be used in edible applications but not all of them are suitable for food or forage. Industrial oilseed meal from crambe abyssinica contains relatively high levels of protein that is not suitable for human or animal consumption due to the presence of anti-nutritional compounds. This paper presents research on crambe meal as a base for new plastics, developed to extrude continuous, flexible plastic films based on crambe meal, blended with vital wheat gluten as an elastic component and urea as a protein denaturant. The effect of process parameters, such as screw speed, die temperature and pressure, and the effect of components were studied with regards to the final performance of the film extrudates. E.g. mechanical properties, oxygen permeability and moisture content were determined and surface and cross-section morphologies were examined with electron microscopy. The results showed that crambe-based blends can be extruded as continuous, flexible plastic films, which exhibit barrier properties towards oxygen. Recipes and methods for pelletizing of master batches for post-converting (e.g. extrusion or compression molding) were successfully developed. Addition of arenewable plasticizer improved the extrusion performance and resulted in less hygroscopic films, which further showed the overall highest tensile strength while the extensibility was nearly unaffected. The results provide a first basis to further develop the process and the blend towards potential industrial applications, for example as packaging materials to trays, pots and similar type of packages.

    Will Clothing Be Sustainable? Clarifying Sustainable Fashion2016Inngår i: Textiles and Clothing Sustainability: Implications in Textiles and Fashion / [ed] Subramanian Senthilkannan Muthu, Singapore: Springer Science+Business Media B.V., 2016, s. 1-45Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    The Mistra Future Fashion research programme (2011–2019) is a large Swedish investment aimed at reducing the environmental impact of clothing consumption. Midway into the programme, research results and insights were reviewed with the intent to see what picture appears from this interdisciplinary consortium, developed to address the multiple sustainability challenges in clothing consumption and the tools for intervention. Such tools comprise product design, consumer behaviour changes, policy development, business models, technical development, recycling, life cycle assessment (LCA) and social life cycle assessment (SLCA). This chapter quantifies the extent of the sustainability challenge for the apparel sector, via an analysis of five garment archetypes. It also considers to what extent different interventions for impact reduction can contribute in society’s endeavour towards sustainability, in terms of staying within an “environmentally safe and socially just operating space”, inspired by the planetary boundaries approach. In particular, the results show whether commonly proposed interventions are sufficient or not in relation to the impact reduction necessary according to the planetary boundaries. Also, the results clarify which sustainability aspects that the clothing industry are likely to manage sufficiently if the proposed interventions are realised and which sustainability aspects that will require more radical interventions in order to reach the targets.
