Communicating Sustainability: How Civic Actors, Digital Technology, and Awareness Campaigns Shape Waste Management Behaviours

<p dir="ltr"><i>Sustainable waste management is critical to achieving the sustainable urban development goal of most cities. It requires coordinated efforts from policymakers, civic actors, and residents. This study investigates the impact of civic actors, persuasive digital technology, and awareness campaigns on sustainable waste management behaviours in Singapore. Semi-structured interviews with civic organisations (N=11) involved in sustainable waste management reveal their role in translating policy into grassroots action through digital engagement, behaviour change strategies, and sustained community participation in waste reduction initiatives. In addition, a survey of Singaporean residents (N = 508) examines public awareness, attitudes, and responses to sustainability campaigns. Findings indicate that while digital tools enhance awareness and participation in waste management, lasting behavioural shifts remain influenced by civic-led initiatives, resource availability, community-driven efforts, and effective message framing. The study highlights how communication strategies, civic engagement, and technology adoption interact to promote sustainable waste practices and increase awareness. This research contributes to the ongoing discussion on sustainability communication approaches and offers practical insights for advancing urban sustainability efforts through citizen-driven action and supportive policy.</i></p>
