Key Performance Indicators (KPIs) act as
an existing tools to measure the source separation programmes and activities by providing several monitoring
parameters under the main elements which are recycling rates and participation level of source separation. The
source separation programme and activities need to be continuously implemented in order to get the high level of
public participation which subsequently increases the recycling rate. As mentioned by Guerrero et al. [22], the
individual behaviour to segregate the waste can be influenced through awareness campaigns due to their
environmental concern and participation to overcome the associated issues.
