Residents’ waste management practices in a developing country: a social practice theory analysis

Waste management has become a growing concern globally and caused rising environmental costs in developing countries. The efficiency of a waste management system depends on many factors, including residents’ waste management practices and a governmental commitment to sustainable waste management. This study employs the social practice theory to qualitatively examine residents’ perspectives on waste management in the context of Vietnam as a developing country where a massive portion of plastic waste originates from household disposal. The research involves conducting twelve focus groups in five different research locations, including two largest cities and three coastal and marine protected areas. Data analysis is performed using inductive and deductive coding principles and an interpretivist approach. The findings reveal residents’ classification of sustainable and unsustainable waste management practices, and the factors that facilitate or impede sustainable waste management practices from residents’ perspectives. According to residents, while adequate technical infrastructures can facilitate sustainable waste management practices, it is the social context that motivates or demotivates and can mould a practice into a habit. The study therefore provides useful implications for sustainable waste management systems that would require the government's effective leadership and coordination of technical infrastructures as well as the orchestral efforts from involved social institutions, including families, communities, businesses, formal and informal waste sectors, and social organisations.
