Dhaka, the capital of Bangladesh, is the eleventh largest megacity city in the world, with a population of 18.2 million people living in an area of 1528 km 2 . This city profile traces the trajectories of its urban development to becoming a megacity and characterizes its emerging challenges due to informal urbanization and climate change impacts. Due to rapid population growth and uncontrolled urbanization, Dhaka currently faces various socio-economic and environmental challenges in aspects such as providing basic urban services; reliable transportation framework; constant water and energy supply; effective sanitation; sustainable waste management and affordable housing. Moreover, the urban setting has further deteriorated as Dhaka is already facing various adverse impacts of climate change. Studies predict that most of the urban sectors, public health and surrounding agriculture and fisheries in Dhaka will be severely impacted by climate change. Dhaka is trying to transform its existing "incremental development" model to an "integrated development" framework in order to effectively mitigate its extreme urban challenges. The future of Dhaka city significantly relies on the successful execution of integrated infrastructure and service planning, development, and management practices, operating under an accountable and good governance system.

The Dhaka City Corporation (DCC) is primarily responsible for collecting and managing waste in Dhaka, Bangladesh. A significant amount of waste in Dhaka is not collected due to lack of infrastructure, funds and collection vehicles. Despites Dhaka's limited waste management service, community based door-to-door waste collection from households to local waste bins is considered as a success. Informal waste recycling systems is also highly effective in waste recycling and job creations for the poor. Even though both horizontal and vertical expansion is prevalent in Dhaka, there has been an increasing trend in vertical expansion of the city in recent years as horizontal expansion is not possible due to barriers such as the built up urban core and low lying flood plains. Very limited number of studies has been conducted on waste management system in high-rise residential buildings in Dhaka. Therefore, this study focuses on the waste management scenario of high-rise residential buildings in Dhaka. The study is particularly interested in the socio-demographic, cultural and environmental features in high-rise residential buildings. The study identified key areas in waste management systems in high-rise residential buildings which is the avenue for future studies for integrating waste management strategies in high density residential development in Dhaka. Based on the findings, the study recommends a further examination of the integration of waste management infrastructure in the high-rise residential building development in Dhaka.
