Executive Summary
Leachate Treatment Efficiency at Amin bazar & Matuail Landfills. The effectiveness of cotreating leachate in municipal treatment facilities has come under scrutiny in light of the stricter regulations imposed on wastewater discharge in recent years.
In order to lessen the environmental impact associated with municipal solid waste landfills, landfill treatment for leachate is required. The study was conducted on the efficiency of leachate treatment facility situated at Matuail and Amin bazar landfills based on two parameters which are heavy metal and micro-plastics.
To increase the efficiency of the two leachate treatment facility at Matuail and Amin bazar landfills the methods for removing micro-plastics and heavy metals have been discussed.
Background of the Study
The disposal of non-segregated solid waste at landfill sites is a commonly observed waste management technique in poor nations, such as Bangladesh. During the process of waste disposal, solid waste undergoes gradual and oxygen deprived decomposition, lasting approximately 30 to 50 years.
There is a risk that these substances may permeate from the landfill site into underground aquifers, thereby contaminating crucial urban water resources. Landfill leachate is composed of a diverse array of substances, including significant quantities of refractory organics, tiny organic molecules, toxic heavy metals, inorganic minerals, and organic residual contaminants, which exhibit varying concentrations.

There are several reasons that may contribute to the presence of heavy metals in leachate from landfills. Approximately 2.8 million metric tons of electrical garbage, which contains hazardous substances such as mercury (Hg) and lead (Pd), are annually created and then disposed of in landfills, agricultural areas, and bodies of water.
Problem Statement
At present, The waste management system in Dhaka is now facing challenges in effectively managing a substantial amount of garbage, estimated to be over 4500 tons per day. At present, the Dhaka South City Corporation (DSCC) and Dhaka North City Corporation (DNCC) are served by two landfills located at Matuail and Amin bazar, respectively. The effectiveness of a treatment facility may be assessed by conducting a comparative analysis of heavy metal and micro-plastic concentrations in both raw and treated 20 leachate. The purpose of this study is to provide a comprehensive explanation and justification for the chosen research approach and methodology.

Research Objectives
Broad objective
Landfill leachate is a significant source of micro-plastic and heavy metals. The leachate treatment plants’ efficiency can be measured through these two parameters in both raw and treated leachate.
Specific objectives
- To assess the micro-plastic amount in raw and treated leachate.
- To evaluate heavy metal in raw and treated leachate.
Research Questions
Research questions
- How much micro-plastic is present in raw and treated leachate?
- Is the heavy metal concentrations in treated leachate below the permissible limit set by the Government?
- What is the concentration of heavy metals content in raw and treated leachate?
- Is the amount of micro-plastic substantially low in treated leachate than raw?
Conclusion
Physical, chemical characterization as well as the concentration of heavy metals and micro-plastics was analyzed in raw and treated leachate to determine the effect of leachate on surrounding water bodies.
This study has been conducted focusing on the efficiency of leachate treatment facility of Matuail and Amin bazar landfills through measuring the removal rate of micro-plastic and heavy metals in leachate. To remove micro-plastics and heavy metals various methods were gathered from list of papers that mentioned significant removal rates of micro-plastic and heavy metals to increase the efficiency of leachate treatment facilities.
