Conceptualising "zero-waste city" in the context of Bangladesh

The Finantial Expres - A consumption-driven society produces a large amount of waste. This massive amount of waste puts enormous pressures on management of city waste effectively. Waste management is a priority area in city governance. City waste management is crucial for sustainable development. It is also required for achieving Sustainable Development Goals (SDGs) as SDG 11 deals with solid waste management in a sustainable manner. But the city planning process in Bangladesh is yet to focus on modern waste management conforming with the SDGs.  Designing sustainable cities is a very challenging task, especially when it has to conform to the SDGs. In densely mega cities like Dhaka, large amounts of daily waste create a huge impact on city life. For example, the recent water-logging of Dhaka city has been observed as a partial consequence of the poor city waste management. Moreover, the present waste management system is not suitable for tackling global climate change and its effects on human life are accelerated through generation of global greenhouse gas (GHG) emissions, landfill methane (CH4), emissions of carbon dioxide (CO2) resulted from waste containing fossil carbon (plastic or synthetic textiles). The concept of "zero-waste city" is to deal with the GHG issue with provision for sustainable waste management and emission reduction.
