Changing laundry habits in Norway

Maintenance is often the most energy‐demanding stage during clothes' life cycle. Therefore, a shift towards more sustainable washing habits has great potential to reduce the consumption of energy, water and detergent. This paper discusses the change in laundering practices during the past 10 years in Norway and suggests strategies to help consumers change their laundry habits to more sustainable ones. Quantitative information of consumers' experiences, habits and opinions concerning clothing maintenance was collected through three surveys in Norway in 2002, 2010 and 2011. The 2010 study was supplemented with qualitative in‐depth interviews of a strategic sample of households. The average washing temperature has decreased slightly during the studied time periods. Some products' washing frequencies remained the same, whereas other products such as jeans were used a few more days before washing. The cotton programme is the most used washing programme, but short programmes are gaining popularity. The laundry sorting processes vary greatly and are influenced by several factors such as washing temperature, colours, fibre type and use area. For some consumers, the use of several different sorting categories made it more difficult to collect a sufficient amount of clothing to fill the machine. They were also afraid that overfilling the machine would result in clothes that were not clean enough or had detergent residues. Detergent dosing practices are far from optimal. In 2010, although the majority of respondents only used eye measure and did not know the water hardness of their area, they still tried to vary detergent dosage based on the amount of laundry and the level of soiling. Different design for sustainable behaviour strategies could be used within detergent dosage systems, care labelling, machine programme selection (such as suggesting lower temperature and eco‐programme), machine filling grade indicators, storage systems for slightly used clothing and textile material choice.     

Comparison of the washing efficiencies of a laboratory washing device (Launder‐Ometer) and of automatic household washing machines with horizontal drums

The objective of this study was to compare the cleaning result of a laboratory washing machine – Launder‐Ometer (LOM) – with that of drum‐type household washing machines, using detergent without bleaching agent, standard soiled fabrics and a colorimeter for assessing the washing result. The mechanical effect applied to the laundry in the household washers was not obtained in the LOM by increasing mechanical impact or the number of metal balls. Extended washing time did not improve removal of blood soil in the LOM, although it did increase removal of mayonnaise soil containing chlorophyll. However, in practice a washing time of 60–85 min is relatively long for a laboratory device considering the claimed time‐saving nature of these devices. None of the examined parameters affected removal of a red wine soil containing tannins, which was poor in all test combinations both in the household machines and in the laboratory washing machine. Bleaching agent is recommended for removal of this type of soil. In conclusion, conformity between washing results of the laboratory washing machine and the drum‐type household washing machines depends on the type of soiled test fabrics and other parameters in the washing process. Removal of blood soil differed most between the household machines and the LOM.     

Choices and using of washing machines in Chinese households

Rapid urbanization and improvement in living standard skyrocket the demand for washing machines in Chinese households, especially in urban households. This paper discusses the owning rate of different types of washing machines, using frequency, load capacity, factors affect choices of washing machines, etc. in Chinese households and suggest possible strategies in choosing washing machines considering economic expenditure. Quantitative information relates to choice and use of household washing machines was collected through in‐depth interview of the key person who carried out household laundering. A total of 993 households that were randomly selected in eight provinces and a municipality were successfully interviewed. Impeller washing machine is still in a dominate place whereas drum washing machine increasing steadily. Households with higher income tend to buy drum washing machines for their better performances in detergency and superior quality. Load capacity between 4 and 6 kg is very common at present. Larger load capacity is a trend of washing machine choices in Chinese households. Washing machine with better energy efficiency is more popular for its lower expenditure in use. This is more obvious for drum washing machine. Washing machines are often used once every 1 or 2 days in summer, whereas one wash per week and two washes per week are very common in winter. Consumer will expend much more money with the choice of a drum washing machine, not only for paying for the machine, but also for the consumed electricity and water and wastewater discharges in every use.     

An investigation into aspects of energy labelling with special reference to washing machines

The purpose of this research was to investigate whether the performance of domestic washing machines is adversely affected by reduced levels of energy use. This was felt particularly worthwhile because of the introduction of energy labelling for washing machines in April 1996. Results were determined by conducting tests derived from BS EN 60456. This research also aimed to discover consumer awareness of energy labelling and factors likely to influence the future purchase of washing machines. The results indicate that washing performance may be adversely affected by lower levels of energy consumption and that washing machines with a higher energy consumption achieve a better washing performance. From the survey carried out, it was discovered that the most influential factors when purchasing a washing machine were price, washing performance and brand reliability. Environmental factors such as reduced energy consumption and reduced water consumption only played a minor role in consumers' considerations. However, the research indicates that consumers' decisions may, in the future, be affected by the information displayed on energy labels.     

Can Hand Washing Influence Hedonic Food Consumption?

The act of hand washing has been a routine part of hygienic practices across time and society. Aside from its physiological effects, hand washing has also been shown to symbolically cleanse individuals of their transgressions. However, most research demonstrating the metaphorical effect of hand washing has mainly been focused within the domain of morality. The objective of the current research is to explore the role of hand washing on consumption behavior, and more specifically, hedonic food consumption. Across two studies, this article establishes the role of hand washing after hedonic food consumption as well as prior to a hedonic food choice. In Study 1, washing one's hands after consumption of hedonic food decreased perceived guilt. In Study 2, washing one's hands prior to choice led to an increased likelihood of choosing a more hedonic (compared to less hedonic) food item. Thus, by washing one's hands, individuals are provided with a license to indulge in hedonic foods without the guilt that is commonly associated with such a choice. Several implications for consumer behavior research and the effects of hand washing on food decision making are discussed.     

The adoption of sustainable laundry technologies by US consumers

The adoption of sustainable laundry technologies by US consumers has lagged behind that of other countries and even behind the projections for adoption made by the US government. Most US household currently own and use the top‐loading vertical axis (v‐axis) agitator type washers, which use large amounts of water as well as additional energy to heat the water. More sustainable laundry practices include the use of energy‐ and water‐efficient front‐loading horizontal‐axis (h‐axis) washers. These washers have been demonstrated to use 38% less water and 58% less energy than the standard top‐loading v‐axis models. The adoption of more energy‐efficient washing technologies is of interest to many, including policy makers, because of their water‐ and energy‐saving potential. Little is known about the attributes and issues consumers use in their decision to adopt high‐efficiency washers for their home. This study uses Roger's Diffusion of Innovations Theory to understand the adoption of h‐axis washers by US consumers. An online survey of 330 consumers who own washing machines found that 23% currently own h‐axis washers and 24% of consumers intend to purchase an h‐axis when they replace their top‐loading vertical (v‐axis) washers. Energy and water savings are the most frequently cited reasons overall for adopting the h‐axis washer and cost was the main reason for not adopting the technology. Other issues, such as dissatisfaction with cleaning power and problems with machine cleanliness and maintenance, did not play a major role in adoption. Specific marketing and education channels, where US consumers are looking for information about h‐axis washers, are also identified. Overall, the results suggest that the rate of h‐axis adoption in the US is accelerating, but that many of the benefits of the technology are not easily observed by non‐owners.
