Municipal Solid Waste Management and Waste-to-Energy Potential from Rajshahi City Corporation in Bangladesh

Abstract

Waste management is becoming one of the most challenging tasks for developing countries in order to ensure good human health, as well as a healthy environment. Rajshahi City Corporation (RCC) is one of the 12 city corporations in Bangladesh. Various environmental and human health problems have arisen due to a lack of proper knowledge of waste management. Thus, the aim of this work is to illustrate the present status of MSW generation and management in Rajshahi City Corporation, Bangladesh. Fifty households were selected throughout RCC for waste collection, which represent approximately all types of households in RCC. From the qualitative and quantitative analysis, it is estimated that the approximate MSW generation in RCC is 358.19 t/d (tons/day) at an approximate rate of 0.4214 kg/person/d. Calorific values of the wastes have also been determined using the ultimate analysis results of the MSW. A higher calorific value of the dry MSW has been calculated as 14.9 MJ/kg. Moisture content of the MSW has been found to be 48.28%. It is also estimated that the possible power generation (steam energy to electrical power) from MSW generated in RCC is 159.40 MWh/d. Lastly, future scopes of MSW management and different waste management measures that need to be taken are illustrated. Waste-to-energy (WTE) conversion has been given priority and anaerobic digestion (AD) has been found to be an interesting prospect in this sector. Techno-economic analysis of the AD has been conducted. Energy potential from the proposed plant has been calculated as 3.85 MW and the payback period has been found to be 4.9 years. It has been observed that employing AD on a large scale can not only reduce the waste, but also meet a large portion of the energy demand of this city.

Assessing Sustainable Waste Management Practices in Rajshahi City Corporation: An Analysis for Local Government Enhancement using IoT and AI Technology

“…Bangladesh is third among nations in terms of waste production. Bangladesh generates approximately 0.41 kilograms of waste per person every day (Habib et al, 2021). In this aspect, on average, per person is generating 414 ton/day of waste in the RCC (Table 1).…”

“…This study, with its varied emphasis, focuses on the Rajshai City Corporation (RCC) of Bangladesh. This city, which is in the middle of the Indian subcontinent, is the ideal illustration of the diversity of urban life that can be observed in a developing nation (Habib et al, 2021;Imran & Islam, 2015;Rahman & Jakia, 2015). The di culty of managing waste in this city can be understood in the context of the more signi cant issue of managing urban waste on a global level (Alam et al, 2013;Bari et al, 2012).…”

Pyrolysis of municipal solid waste: Kinetics and thermodynamic parameters via Coats-Redfern method

“…During winter season, in most Asian countries, there is a serious issue of photochemical smog [13] which is mainly produced by particulate matter and smoke produced by open burning and other industrial combustion processes. A proper management of solid waste and its utilization for energy production could be the better strategy to overcome the issue of carbon emissions and solid waste management [14] . There are several methods of biomass utilization such as direct combustion and pyrolysis to obtain different product like gaseous and liquid products along with the carbon-rich material that has many broad applications as a catalyst and adsorbent in many industrial applications [15] .…”
