Quantitative and qualitative investigation of consumer practise and motivation on cleaning dishes in four European countries

In comparison to dishwashing by hand today's dishwashers save much time, energy and water. But even if dishwashing machines are present in more and more households, hand wasing becomes not completely redundant. There are always dishes, which are too bulky or not suitable for the dishwasher, or which need to be prerinsed because of the soiling. Since larger improvements of the efficiency of dishwashing machines are not expected in the future, savings with the consumption of energy and water for dishwashing is to a large extent controlled by the behaviours of the consumer. However the knowledge about practices and habits in the households are very limited, publicly accessible studies about dishwashing rare. Therefore this study examines comprehensively the attitudes and habits of European households with dishwashing. Apart from measurements of the usage of time, energy, water and detergent also aspects of the satisfaction with the results will be regarded more near. The investigation tries to answer the question, which dishes are cleaned in the machine and which and why selected dishes are cleaned further by hand. Likewise observations of the individual operational sequences from the accumulation of soiled table-ware after meal up to granting the cleaned dishes into the cabinet are planned. With the help of this study information will be won to make statements about sustainable behaviour at dishwashing and to improve the offer of dishwashing products.
