Die produktspezifischen Treibhausgaseinsparungen wurden anschlie\u00dfend exemplarisch f\u00fcr eine Glaukomsprechstunde am Universit\u00e4tsklinikum Erlangen sowie f\u00fcr Gesamtdeutschland skaliert.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ergebnisse und Diskussion<\/jats:title>\n                    <jats:p>\n                      Die Ergebnisse zeigen, dass sich durch den Wechsel von Einweg- zu Mehrwegmessk\u00f6rpern 44\u202f% der mit den Messk\u00f6rpern assoziierten Treibhausgasemissionen einsparen lassen.

Zudem hat die Analyse gezeigt, dass Mehrwegmessk\u00f6rper durch den Reinigungsaufwand in einigen Umweltwirkungskategorien zu Mehrbelastungen f\u00fchren. Besonders relevant sind hier die Desinfektionsflasche und die T\u00fccher, die zum Trocknen der Mehrwegmessk\u00f6rper verwendet werden.
