Wie Hände trocknen?
Wissenschaftlichen Studie: "Environmental and Economic Perspectives in the Analysis of Two Options for Hand Drying At an University Campus" (Carvalho et al. 2017)
Die Studie vergleicht die ökologischen Implikationen sowie die Kosten bei der Anschaffung und während des Betriebs von 5 verschiedenen elektrischen Handtrocknern sowie 3 verschiedenen Papiervarianten an einer brasilianischen Universität.
Ausschnitte aus dem Fazit der Studie:
The results obtained herein indicated that per dry, the use of an electric hand dryer presents lower overall carbon footprint than the utilization of paper towels. This was based on the use phase, represented by a campus building located in Northeast Brazil.
The use of electric hand dryers presented lower overall annual costs and environmental impacts. Equipment 2 presented the best compromise between cost and environmental impact, with only 25% of the cost associated with the cheapest paper towel option, and only 13% of the environmental impacts associated with the best environmental option for paper towels. However, despite these promising and encouraging results, electric hand dryers are not the preferred method for hand drying in public restrooms due to consumer rejection: many have not adapted to this technology, and many resist to even trying it.
