Abstract

© 2017 19th ICSMGE Secretariat. All rights reserved.In this study, natural water content, organic matter content, specific gravity and pH values of the fresh and aged synthetic waste samples in different compositions were examined. In order to determine composition effect on the physico-chemical properties three synthetic MSW compositions were composed by using 11 different waste materials. Synthetic samples were prepared in representative different compositions as average compositions of Europe (E), Turkey (T) and the United States of America (U) to examine the effect of the composition on the physico-chemical properties. In addition to E, T, and U compositions, the modified compositions were prepared by extracting some materials or decreasing the percentage of dominant materials in the composition. The specific gravity values were 1.72, 1.27, and 1.90 for E, T and U compositions. The pH values of the E and U compositions were obtained as 5.9. However, T composition has higher pH value (10.5) because of higher ash content in the composition. As ageing progress, the pH values of E and U compositions increased.
