Energy security evaluation through solid waste management in Dhaka city, Bangladesh

Energy security is usually the relationship between national security and natural resources for energy production in a particular state for which enhancing energy security to produce sustainable energy production has made it significant. Furthermore, being an occupied nation Bangladesh hopes to be an advanced country by 2041, and hence, electricity enhancement is significant for any nation’s sustainable development. Therefore, investigation on energy security in Bangladesh should be continued so that shortage of energy demand can be resolved, such as solid waste conversion to energy production. However, solid waste management (SWM) is one of the most severe ecological complications threatening urban areas, especially in Dhaka, the capital city in Bangladesh. Research shows that swift growth rate has boosted up surplus and thereby it is important to find the alternate option in the energy process from waste. With this view, an evaluation of the power enhancement through SWM and energy production in Dhaka city corporation (DCC) stipulates the prospects and skills well-matched for Bangladesh. The study shows that the rate of waste production was increased from 1.00 million to 4.5 million tons from the year 2000 to 2050 for which electricity generation is 340 GWh in 2000 whereas, the projected value is 1444 GWh in the projected year through the incineration process under the context of ultimate analysis. It is also observed that the daily waste generation in DCC is about 3768 tons in 2005 and thereby, producing a total of 1.38 million tonnes in a year which will be doubled by 2030. Hence, this huge amount of waste will emit a significant amount of CO2 for which the mixed mode of SWM and energy production process could be recommended so that the policymakers can take the decision about adopting the WtE technology through SWM for a better environmental place and sustainable economy.
