ANALYSIS OF PHYSICAL AND CHEMICAL COMPOSITION OF THE SOLID WASTE IN CHITTAGONG CITY

Abstract

The present study was carried out to determine the physical and chemical composition of the Chittagong city. Fine organic materials comprises the major part of the produced solid waste (35.1%), while fine dust and vegetable matter constitute 28.5% and 20.6% respectively. The major components of municipal waste include food waste, glass, metals, can, debris, bricks, boards, leaves, paper, dirt and ashes, chemical composition found in the solid wastes showed high moisture content, high ash and inorganic contents and comparatively low nitrogen, phosphorus and potassium. The nitrogen, phosphorus and potassium content represent the important ingredients value for fertilizer of the waste and potential conversion of the waste into good compost. The leachate characteristics showed acidic in nature. It is also rich in nitrate and phosphate, whenever this highly polluted leachate got entrapped in ponds with the surface wash, it poses a high degree of pollution threat to ground water as well as surface water and subsequently health hazard.
