“…Therefore, the average waste production was calculated as 0.4214 kg/person/d. Similar results have been observed in previous studies [7,9]. According to the Rajshahi City Corporation authority, the population of the city is approximately 0.85 million [22].…”

“…According to the Rajshahi City Corporation authority, the population of the city is approximately 0.85 million [22]. Therefore, the approximate total waste generation in RCC is calculated as 358.19 t/d, which is approximately equal to the data presented by earlier studies [7,9]. The total estimated waste generation per day as well as per person is similar to the results obtained from the previous studies.…”

“…It is clear that, in the last few years, researchers have worked on illustrating waste management systems in different major cities of Bangladesh. A number of works have been done on the waste management scenario in RCC, Bangladesh [7,14,15]. Possible energy generation was also estimated by various methods [9,11,16,17].…”

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.

“…In many economically disadvantaged regions, an informal local recycling sector exists via a system of waste pickers that sort through dumpsites to collect saleable materials such as metals, plastics, glass, and papers [21,[29][30][31][32][33]. Often, waste pickers travel throughout communities of rural regions and cities to collect recyclables from house-to-house as well, or set up recycling drop-off locations, paying individuals a small incentive for valuable materials.…”

Unsound post‐consumer disposal is the primary pathway of plastic into the ecosystem. One way of addressing this problem is through the establishment of a circular economy for plastic. Much of the unsound disposal comes from economically disadvantaged regions where waste disposal and recycling infrastructure is limited. In economically disadvantaged regions however, the establishment of a circular economy for plastic must be locally managed and decentralized, meaning that the disposal, collection, remanufacture, and use must all occur within the same community. We suggest that waste plastic abatement strategies must be targeted to reduce, reuse, and recycle plastic waste onsite at the local level, initiating a circular economy appropriate for infrastructure limited regions. Technologies for recycling plastic must be low cost, economically viable, socially acceptable, and not adversely impact the environment, and also produce a product that has a ready local market. This is critical because unless proposed solutions are also economically viable and socially appropriate, they are unlikely to be successful, especially in underdeveloped regions. Using big data analysis, a metric for identifying countries that will have the most potential to benefit from a locally managed decentralized circular economy for plastic has been developed. The information obtained from this metric will help researchers and policy makers promote a locally managed decentralized circular economy of plastic for managing the accumulation of waste on land and its eventual migration into waterways. Additionally, we present a case study of a proposed locally managed decentralized waste plastic abatement strategy in the municipal solid waste infrastructure limited country of Uganda. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 3–11, 2019

Environmental pollution by various recalcitrant molecules, metals, and metalloids has increased during the decades principally due to the effluent discharges, trashes, garbage, oil spills, chemicals, sewages, etc., from the growing industries posing the major health risks along with the possibility of propagation of communicable diseases. To deal with such a vast clump of environmental pollutants, application of bioremediation has long been known as the supreme biotechnological method because of its eco‐friendly nature. However, the applicability of bioremediation is still obscure except some specific fields to many of the developing countries like Bangladesh. Nevertheless, the toxicity caused by the environmental pollutants has been chalked out to some extent in this country whereas a vast field of environmental cleanup is yet to be resolved. In the present review, the global knowledge and practice of bioremediation has been discussed and the areas of bioremediation strategies in context to Bangladesh have been focused.
