Abstract: Purpose of the study is to reduce waste dumping system on open pit and reduce greenhouse gases (GHG) emission by produce electricity from wastes. Furthermore, safe the surface water from the wastes. The study found that the wastewater from Dhaka city contained a diverse array of chemicals including toxic and nontoxic heavy metals, nitrates, phosphates, and harmful polyaromatic hydrocarbons that from organic or inorganic wastes. The experiment has done on wastewater sample collection and direct data collection. Then the data analyzed by the software simulation. The results are that 80% waste collection rate and High tech solid waste incinerator/treatment plan could produce per day 233MW electricity and potentially reduce totally 1.9-2.0 million tons GHG per year. In addition, by the analysis of this High Tech plan could reduce roughly 60% polluted wastewater effluents.
