Analysis and optimization of current and future practices
in the solid waste management systems are complex tasks.
There are qualitative evaluations like the ones suggested
by Zurbrügg et al. (2012), who have developed a qualitative
set of indicators applied to check the sustainability of
the Indonesian solid waste management and by Permana
et al. (2015) who have discussed the regional solid waste
management system for Makassar City (Indonesia), based on
questionnaires.
