initial values are estimated more or less correctly by the experts, we might conclude
the following main statement of this part of the research: the ranking of the factors
below in
uencing the sustainability of the waste management systems shows the
way how the roles and weights of the factors should be considered within an IWMS
in order to ensure environmental ef
fl
ciency, economical affordability and social
acceptability, this way providing a comprehensive interdisciplinary framework for
addressing all problems of managing urban solid waste.
1. C1 (technical factor),
2. C2 (environmental factor) and C5 (legal factor),
3. C3 (economic factor),
4. C6 (institutional factor), and
5. C4 (social factor).
