“…Dhaka is also considered to be "one of the largest and most densely populated cities in the world", with a density of 23,234 people per square kilometer within a total area of 300 square kilometers. Approximately 38% of Bangladesh's urban population reside in Dhaka [87,88]. Geographically, this city is located at 23.8103 • N latitude and 90.4125 • E longitude.…”

Composting is a sustainable way of transforming organic waste into valuable organic fertilizers which have the potential to act as soil conditioners by controlling various biological processes. The prime objective of the current study was to determine the influencing factors behind the intent of home food waste composting, by employing the combined model of Theory of Planned Behavior (TPB) and Dualistic Passion Model (DMP). The combined model showed a higher predictive ability in comparison to the individual TPB model. The fit statistic of the integrated model was deemed good, and 65% of the variance for home composting intention was explained. Using a face-to-face questionnaire survey, a total of 203 valid responses were gathered from home gardeners and tested via a unique two-step methodology: the PLS-SEM and the artificial neural network (ANN). The results revealed that the composting intention can be significantly influenced by attitude, subjective norms, and perceived behavioral control. The study also confirmed the positive effect of harmonious passion and the negative effect of obsessive passion on the intention of food waste composting. Furthermore, the hybrid method produced more reliable results because HP was found to be the most important variable in both ANN and PLS-SEM results, while PBC was observed to be the second most important variable in ANN and the fourth most important in PLS-SEM. The results of the current study not only highlight the importance of passion in determining food waste composting intention in Dhaka, Bangladesh, but also provide helpful information for designing effective, sustainable tactics for encouraging residents to compost food waste at home.

“…Discussions on garbage collection by sector without public involvement can be broadly divided into studies that discuss the positive and negative effects of informal sector involvement in garbage collection; the effects of garbage collection through private sector involvement, such as in-store collection; and the integration of the informal sector into the MSW management system. Regarding perspectives on informal sector involvement in waste collection, Kirama and Mayo [ 11 ] and Adib and Mahapatro [ 12 ] argue that while private involvement leads to job creation and increases garbage collection efficiency, wages and benefits are low, and female cleaners are marginalized. Hidalgo-Crespo et al [ 13 ] analyzed the impact of increased recycling rates by waste pickers on the carbon footprint.…”

“…The escalation in demand, production, and consumption has led to a steady increase in the production of substantial quantities of solid waste, and for developing countries, such as Bangladesh, efficacious waste management remains a formidable challenge essential for the attainment of institutional sustainability [3] [4] [5]. Within Dhaka North City Corporation's 26th Ward, colloquially known as the Farmgate Area, an approximate population of 64,240 individuals from diverse backgrounds resides [6] [7]. Inhabitants generate a diverse array of waste, with notable contributions from food and vegetable waste, plastic, bottles, paper, iron, and tin cans [8] [9] [10].…”

This investigation is focused on conducting a thorough analysis of Municipal Solid Waste Management (MSWM). MSWM encompasses a range of interdisciplinary measures that govern the various stages involved in managing unwanted or non-utilizable solid materials, commonly known as rubbish, trash, junk, refuse, and garbage. These stages include generation, storage, collection, recycling, transportation, handling, disposal, and monitoring. The waste materials mentioned in this context exhibit a wide range of items, such as organic waste from food and vegetables, paper, plastic, polyethylene, iron, tin cans, deceased animals, byproducts from demolition activities, manure, and various other discarded materials. This study aims to provide insights into the possibilities of enhancing solid waste management in the Farmgate area of Dhaka North City Corporation (DNCC). To accomplish this objective, the research examines the conventional waste management methods employed in this area. It conducts extensive field surveys, collecting valuable data through interviews with local residents and key individuals involved in waste management, such as waste collectors, dealers, intermediate dealers, recyclers, and shopkeepers. The results indicate that significant amounts of distinct waste categories are produced daily. These include food and vegetable waste, which amount to 52.1 tons/day; polythene and plastic, which total 4.5 tons/day; metal and tin-can waste, which amounts to 1.4 tons/day; and paper waste, which totals 5.9 tons/day. This study highlights the significance of promoting environmental consciousness to effectively shape the attitudes of urban residents toward waste disposal and management. It emphasizes the need for collaboration between authorities and researchers to improve the current waste management system.
