Municipal Solid Waste Landfill Leachate Characteristics and Their Treatment Options in Tropical Countries

Abstract This review assesses the leachate quality from waste disposal sites in tropical climate zone. Through this review, data 228 samples 145 18 countries region were analyzed. The 12 types of considered for analysis based on climatic conditions, age, and operating condition site. Tropical rainforest, monsoon, savanna climates identified zone classification. Age site was classified as young old. conditions engineered landfill open dump Eighteen parameters included analysis. Leachate pollution index indicated that rainforest monsoon have higher potential, while potential did not demonstrate considerable difference terms age landfill. Considering method sites, dumpsites pose potential. Positive correlation could be seen among biological oxygen demand, chemical total dissolved solids, Kjeldahl nitrogen. pH negatively correlated with organic pollutants well heavy metals. Analysis emerging contaminants present is limited region; thus, it recommended to conduct studies contaminants. Further, treatment options are discussed review.
