With the increasing trend of the urban population in Bangladesh, waste generation is also increasing. With 70% organic solid waste, the urban areas generate 23,688 tonnes of waste per day. This rapid enhancement in waste production has an adverse effect onlandfill resources and the day-to-day lifestyle. In this regard adopting waste to energy techniques can be considered good idea to overcome the current waste management problem. This WtE conversion technique solves the landfill resources problem and produces electricity and heat to be supplied. This study aims to investigate the current status of MSW management in Bangladesh and identify the major problems. Here, five fundamental methods such as pyrolysis, incineration, anaerobic digestion (AD), gasification, hydrothermal carbonization (HTC) are reviewed critically and discussed the feasibilities in Bangladesh to generate power. The analysis is done considering different types of parameters like moisture content, calorific value, and residence time. These analyses pertaining to MSW management may be fruitful for encouraging researchers and authorities to improve further.
随着孟加拉国城市人口不断增加的趋势，垃圾产生量也在上升。城市地区70%为有机固体废物，每天产生23688吨垃圾。垃圾产量的这种快速增长对填埋资源和日常生活方式产生了不利影响。在这方面，采用垃圾转化能源技术可被视为解决当前垃圾管理问题的一个好办法。这种垃圾转化能源的转换技术解决了填埋资源问题，并产生可供供应的电力和热能。本研究旨在调查孟加拉国城市固体废弃物管理的现状，并找出主要问题。在此，对热解、焚烧、厌氧消化（AD）、气化、水热碳化（HTC）这五种基本方法进行了批判性回顾，并讨论了其在孟加拉国发电的可行性。分析是考虑诸如含水量、热值和停留时间等不同类型的参数进行的。这些与城市固体废弃物管理相关的分析可能有助于鼓励研究人员和当局进一步改进。
