Source separation also called “in situ segregation of domestic waste” is the sorting out of individual waste types into separate storage containers at the point of generation. From the questionnaire survey, it was revealed that 42.4% (95) of the respondents are separating their waste at their residence while 57.6% (129) do not separate waste at their household. The level of household participation in waste sorting is alarmingly low in the study area. This low participation in waste sorting in the entire sample area could allude to a low level of awareness of environmental issues and low environmental education (formal and informal) which may cultivate into apathy towards waste sorting. However, these further analyses showed that respondent do not have sufficient knowledge on waste segregation. Even though recycling activity in Kuching City is increasing, thus the recycling initiative still needs to be enhanced. The Malaysian‟s attitude towards waste segregation and recycling is higher, but only few practice it [43].
