Due to unplanned rapid urbanisation since the last two decades, the municipality of Bangalore (Bengaluru) struggles to provide adequate waste management (WM) services in the city. In December 2015, as a measure to facilitate semi-centralised treatment, the Karnataka High Court ordered the Bengalureans to segregate waste at source. This study unveils the status quo of solid WM in Bengaluru and investigates the scope for treatment of biowaste at household level. Public awareness on and their contentedness with the existing WM situation, and their willingness to treat biowaste within the household was assessed using online questionnaires. The chosen sample population included Bengalureans mainly belonging to middle class and age group 22-34. Parallelly, experts from different stakeholder groups (in Bengaluru) were interviewed to triangulate data. Despite establishing semi-centralised waste processing centres and other efforts by the municipality; the city still faces a waste crisis, as acknowledged by both groups. Lack of involvement of the public (apathy towards segregation) and non-cooperation of the pourakarmikas or waste collectors (irregular collection, dumping and burning waste within the neighbourhoods, etc.) were found to be the main reasons for the failure of the schemes. Currently, most of the waste processing centres are not functioning and the collected waste still gets dumped inappropriately. The interviewed experts and the survey respondents equally welcome solutions (household digester/composter) for in-situ treatment of biowaste. The price ranges found out in this study shows the expectations of middle class Bengalureans for such systems.
