Measuring the impact of modern waste collection and processing service attributes on residents' acceptance of waste separation policy using a randomised conjoint field experiment in Yogyakarta Province, Indonesia.

ABSTRACT

Indonesia is one of the countries that is facing serious solid waste problems. Although the issue has been addressed in the capital city of Jakarta, many secondary cities have been left behind. This research attempts to analyse the impact of relevant waste management policy components on respondents' policy acceptance probabilities in Yogyakarta Province. Using a randomised conjoint field experiment based on the proposal of modern waste collection services, this article shows that a new waste management policy that includes waste separation with frequent organic waste collection will gain popular support, especially with the rich. Indeed, if the government introduces waste collection and processing services that consist of the most preferred levels of these attributes, including five-times-a-week organic waste collection, a majority of the residents will support this new waste management policy, which will reduce waste at its source.
