RESIDENTIAL SOLID WASTE AT POINT OF GENERATION (A CASE STUDY AL-AMMARAH CITY)

Abstract

Municipal solid waste is of variable, non-uniform inconsistent nature and the method by which the sample is obtained is critical if the results are to be reliable. In this survey the proportional stratified random sampling was adopted, i.e., the total population was divided into groups (socio-income levels) and random samples were taken in each level in its proportion to the total population. Based on the results of the preliminary survey for 99% confidence interval and 10% standard error, held in Al-Ammarah City, the optimum sample size was shown to be 104. An estimate of the total waste generated and physical composition analysis of residential solid waste were carried out at the source of generation, in Al-Ammarah City in Missan Governorate by carrying out a statistically designed sampling survey, Up to 104 units with different socio income level were sampled, yielding an average of 750 kg of waste to be handled in each day for one week. The study showed that Al-Ammarah City have an average generation rate of 0.66 Kg per capita per day, having 44% food waste, 4.9% paper, 4% metal, 4.2 % glass, 1.13% rubber, and textile 4%, 0.6% combustible miscellaneous materials, and 32.3% noncombustible miscellaneous materials.
