Municipal Solid Waste and Leachate Characterization in the Cairo Metropolitan Area

The composition of municipal solid waste (MSW) in the Cairo metropolitan area is investigated. outputs MSW sorting analysis at various locations with different management schemes are presented. Organics (58–75%) and plastic (19–28%) main components a higher percentage organics landfills compared to dumpsites. leachate quality analyzed, results indicate that concentration macro inorganic pollutants (NH4+, Na+, Ca2+, Cl−) heavy metals (e.g., Cd2+ Zn2+) exceeding majority values reported literature cities all over world. There was no evidence an effect recycling process on chloride leachate, while iron reduced. variation time for two samples collected from same landfill first sample two-year-old, second sixteen-year-old. significant increase chloride, sodium, chromium, calcium, magnesium. implications longevity barrier systems discussed.
