Review of clothing disposal reasons

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 Perceived value (35%): reasons where the consumer no longer wants the garment because it is outdated or out of fashion, or no longer is needed or wanted, or is not valued, for example when there is a lack of space in the wardrobe.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.

Product lifetime in European and Norwegian policies

Nina Heidenstrøm, Pål Strandbakken, Vilde Haugrønning and Kirsi Laitala

Abstract

The objective in this report is to better understand how the increased product lifetime option has been positioned in policies over
the past twenty years. By means of policy document analysis, we explore product lifetime positioning in the EU’s circular economy
policies, Norwegian political party programs and official documents, environmental NGO documents, consumer organisation policies
and product policies. Overall, we find little focus on product lifetime between 2000-2015, however, there has been a massive
increase over the past five years. There is still a long way to go in developing appropriate policy instruments to address product
lifetime.

Durable or cheap? Parents’ acquisition of children’s clothing

Ingun Grimstad Klepp & Vilde Haugrønning

Abstract

Parents are faced with a plurality of choices and concerns when it comes to the acquisition of clothing for their children. This paper explores how parents employ longevity in consumption of children’s clothing from a practice-oriented perspective. The material consists of 6 focus groups with 40 parents who have at least one child under the age of 18. The aim of the groups was to establish children’s clothing needs: how many they need of each garment, how long parents expect the garment to last and what they understand as quality in clothing.

The analysis shows that parents mainly opt for an ‘one or the other’ strategy; they choose what they understand as quality, often affiliated with specific brands, and accept paying more for the garment, or they mainly choose based on low prices, and expect less of the garment. Quality is evaluated based on the garments’ durability and function. More specifically, the parents measure the service lifetime of a garment based on the number of seasons it lasts, either in terms of wear and tear or the child growing out of it. The expected lifetime is defined by uncertain sources, from their own and friends’ experiences, and their desire to justify their own choices as well as routinised practices.

Our discussion section employs these findings and contextualise them within product lifetime discourses. By doing this, we provide knowledge about how quality is understood, and how brand and price are used as indicators. We show how lack of information about products, especially on garments, leads to uninformed consumption practices that have consequences for how quality and longevity are prioritised and understood.

Consumer practices for extending the social lifetimes of sofas and clothing

Vilde Haugrønning, Kirsi Laitala & Ingun Grimstad Klepp

Abstract

Consumers play an essential role in efforts to extend product lifetimes (PL) and consumers’ practices can determine how long and active lives products get. Applying the framework of Social Practice Theory, this paper argues that in order to suggest changes to how consumers can contribute to longer product lifespans, research needs to focus on consumer practices. The data material consists of 4 focus group interviews with 38 participants about household goods and 29 semi-structured interviews about clothing.

Previous research shows that consumers’ expectations of product lifetime has decreased, while satisfaction with products is relatively high, which may indicate that product break down and/or replacement is more accepted. Therefore, we argue, it is necessary to focus on social lifespans. Our findings show that products such as clothing and sofas often go out of use or are disposed of before their physical lifespan ends, and it is more common to donate or sell old clothing and sofas than buying the products second hand. There are a number of routinised practices, such as disposal of functional items, that are considered normal, which leads to less reflexivity of seemingly unsustainable practices.

The material in products, or the expectation to the material, is highly influential for practices that can extend the social lifespan, such as maintenance. We conclude that by understanding practices as integrated and influenced by elements of the material, social and cultural, policy interventions may have a greater impact on the social lifespan of products.

Global differences in consumer practices affect clothing lifespans

Kirsi Laitala & Ingun Grimstad Klepp

Abstract

Most studies of clothing and related habits are carried out within a country. However, apparel production and sales are a highly globalized industry, with many of the same large chains operating worldwide. It is thus quite possible that the use of the same mass-produced clothing differs between various geographical areas. Based on a practice theoretical approach, we have studied differences in consumption, use and disposal of clothes in different countries that may affect the lifespan of apparel.

The paper is based on an international survey in five countries with large apparel markets: China, Germany, Japan, UK and the USA. 200 respondents from each country answered to a comprehensive web-based survey on their wardrobe content. We found differences in practices that could affect the lifespans of clothing in these five countries. At the same time, we find many similarities. For clothing acquisition, buying new items dominates in all the five markets, and washing machines contribute to the main chore of keeping clothes clean. Home production and second-hand clothes constitute a very small part of clothing consumption in all five countries. Many respondents showed low sewing skills, and repair activities were done irregularly. Thus, many of the challenges to increasing the lifespans of clothing are similar for all the five countries. At the same time, there are significant differences. These differences open up for the possibility to learn «best practice» by studying the countries and transferring knowledge between regions. When defining use phase in LCA and other sustainability tools, it must be taken into account that despite the fact that clothing is a global industry, consumption is part of local practice.

What Affects Garment Lifespans? International Clothing Practices Based on a Wardrobe Survey in China, Germany, Japan, the UK, and the USA

Kirsi Laitala and Ingun Grimstad Klepp

Abstract

Increasing the length of clothing lifespans is crucial for reducing the total environmental impacts. This article discusses which factors contribute to the length of garment lifespans by studying how long garments are used, how many times they are worn, and by how many users. The analysis is based on quantitative wardrobe survey data from China, Germany, Japan, the UK, and the USA. Variables were divided into four blocks related respectively to the garment, user, garment use, and clothing practices, and used in two hierarchical multiple regressions and two binary logistic regressions.

The models explain between 11% and 43% of the variation in clothing lifespans. The garment use block was most indicative for the number of wears, while garment related properties contribute most to variation in the number of users. For lifespans measured in years, all four aspects were almost equally important. Some aspects that affect the lifespans of clothing cannot be easily changed (e.g., the consumer’s income, nationality, and age) but they can be used to identify where different measures can have the largest benefits. Several of the other conditions that affect lifespans can be changed (e.g., garment price and attitudes towards fashion) through quality management, marketing strategies, information, and improved consumer policies.

Clothing Lifespans: What Should Be Measured and How

Ingun Grimstad Klepp, Kirsi Laitala & Stephen Wiedemann

Abstract

Increasing the use of each product, most often called longer lifespans, is an effective environmental strategy. This article discusses how garment lifespans can be described in order to be measured and compared. It answers two sub-questions: (1) what to measure (units), and (2) how to measure (methods). We introduce and define terms related to clothing lifespans and contribute to discussions about an appropriate functional unit for garments in life cycle assessments (LCA) and other environmental accounting tools. We use a global wardrobe survey to exemplify the units and methods.

Clothing lifespans can be described and measured in years, the number of wears, cleaning cycles, and users. All have an independent value that show different and central aspects of clothing lifespans. A functional unit for LCAs should emphasise both the number of wears for all users as well as the service lifespan in years. Number of wears is the best measure for regular clothing, while number of years is most suited for occasion wear, because it is important to account for the need of more garments to cover all the relevant occasions during a specified time period. It is possible to study lifespan via carefully constructed surveys, providing key data relating to actual garment use.

Wardrobe sizes and clothing lifespans

Ingun Grimstad Klepp, Kirsi Laitala and Vilde Haugrønning

Abstract

It is easy to assume that a large wardrobe is characterized by excessive clothing and high acquisition, with little use of each garment and thus a big environmental impact. However, it is also possible to think the opposite; that the large wardrobe is a result of clothes remaining in use for a long time, that disposal happens rarely, while acquisition can be normal or even low. Whatever the reason, in a large wardrobe it is more likely that clothes become old before the technical life expires. This is because many of the garments are seldom used. Small wardrobes are often presented as favourable for both people and the environment, and as part of an ecological-friendly lifestyle, but we know little about the interaction between wardrobe sizes, longevity and the environmental impact.

In this paper, we investigate this relationship based on survey material from five countries; China, Germany, Japan, UK and the USA. We find that consumers with large wardrobes use their clothes longer, but consumers with small wardrobes use their clothes more often before they are disposed. We conclude that a good utilization of resources is possible with both large and small wardrobes, but in different ways. As we work towards more sustainable clothing consumption, we need to approach consumers differently, in order to give constructive advice to all.

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

Kirsi Laitala, Ingun Grimstad Klepp & Beverley Henry

Abstract

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.

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

Kirsi Laitala, Ingun Grimstad Klepp & Beverley Henry

Summary

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.

When comparing the number of days between the washes of different types of clothes, we found that respondents were likely to use their woollen products about twice as long between washes compared to their equivalent cotton products. We also found that woollen products had a longer average lifespan and were more likely to be reused or recycled. There is a lot of research-based information available concerning the use and re-use of clothing, and we believe there are sufficient results available on which to base LCA studies. Furthermore, we believe that environmental tools that compare different fibres but exclude use phase provide misleading results. Including the use phase in fibre ranking benchmark tools will improve the rigour and accuracy of these tools for all fibres, compared to reporting results for fibre production only. However, we have also shown that there are several methodological, conceptual and empirical knowledge gaps in existing literature.
