| Popis: | To achieve a system that is closer to a circular economy, the collection of waste has to be improved, as to recycling something, it first needs to be collected. While the waste recycling infrastructure already is very highly developed in many countries of the European Union, the participation of the population (eg. their waste sorting behaviour) still shows a lot of potential for improvement. This study examines the major drivers that influence the waste separation behaviour of a population. First an extensive literature research was conducted, with the target to identify drivers that were already discovered in former studies. These drivers were then divided in two categories: the non-demographic drivers and the demographic drivers. Each of the categories included 12 drivers. These drivers, divided in their categories, were then presented to three groups: experts group in sustainability, waste management and behavioural science, a population group of Leoben and that of Barcelona. These groups were asked to rank the drivers within their proper categories. Furthermore, they were asked to rate the categories of “non-demographic drivers” and “demographic drivers” in percent, according to their perceived influence on waste separation behavoiur. The obtained data was then processed in MS Excel in pairwise comparison matrices, which are a part of the Analytich Hierarchy Process, which is a form of Multi Criteria Decision Analysis. This process is used to structure complex deciscion making problems by comparing criteria (drivers) pairwise. By this process, weightages for the drivers were obtained, according to the perception the group has on how important a driver is for waste separation behavhiour. The results show, that in total the most important drivers are internal drivers like “Beliefs and values”, “Environmental concern” and “Habits”. However, for the experts group the most important driver is “Convenience of the collection system”. In summary it can be said, that it is important to create an environmentally conscious society which develops environmentally friendly behaviour. This society should then be supported with with a convenient collection system. The most important demographic drivers are “Level of education” and “Location”. Level of edcuation is being related to the knowledge about environmental issues and the understanding of the recycling process. This means, target should be to educate people in their early years of education about this topics. So that not only people with higher educational levels obtain access to environmentally related knowledge. This way a more environmentally conscious society could be built. The driver “Location” seems to be most important because it defines the collection system a person participates in. Therefore, it defines the convenience a person experiences while participating in waste separation. Like mentioned before, the target should be to support all members of a waste conscioius society with a convenient collection system, to facilitate the transition of environmentally friendly attitude into actual behaviour. The comparison of the ratings for the non-demographic drivers of the population groups did not show a significant difference in perception. However, the perceptions of the demographic drivers differ more strongly. This reveals, that the two populations still have differences in their perception about waste separation. Another important fact is, that all the groups see the non-demographic drivers as clearly more important than the demographic ones. Especially the consent between all the questioned groups (Barcelona, Leoben and experts) is remarkable Objectius de Desenvolupament Sostenible::11 - Ciutats i Comunitats Sostenibles::11.6 - Per a 2030, reduir l’impacte ambiental negatiu per capita de les ciutats, amb especial atenció a la qualitat de l’aire, així com a la gestió dels residus municipals i d’altre tipus |
