Scenario of Solid Waste Generation Disposal and Transportation at the University of Rajshahi

This paper presents an investigation on present scenario of solid waste generation, disposal and transportation at the University of Rajshahi and at same time focus is given on quantitative analysis and energy calculation of the wastes in the university. Quantitative analysis shows that the average amount of solid waste generated per day is 7.6 ton and the calculated average per capita per day is 0.57kg ± 0.44 although these numbers may vary from region to region. The total waste generated per month and per year is approximately 229.5 ton and 2754.9 ton respectively. The estimated lower heating value (LHV) of the waste is 83412.3MJ/day from where 4.63MWh electricity can be generated using conventional waste fired power plant (WTE) with efficiency 20%. Although literature study on WTE plant showed that for economically viable WTE plant the throughput must be at least 100ton/d or above which means the waste produced in the university per day is not enough for installing a feasible plant but considering whole Rajshahi town a plant of higher throughput can be installed and economically manageable. Otherwise only for environmental benefits the waste can be burned and diminished by small scale modular incinerator.
