Changes in the Solid Waste Composition of Metropolitan Cities: A Case Study for Izmir

Knowledge of municipal solid waste amount, composition and characterization in an area plays a key role for the decision makers to determine the proper waste management system and final disposal options. Depending on various factors such as population increases, climatic changes, lifestyle habits, and socio-economic developments, the solid waste amount and composition continuously change in time. Lack of waste data is a big problem in Turkey which is a developing country with young population and rapid industrialization. There are numbers of composition and characterization studies conducted in different districts in Turkey by independent researchers. Nevertheless, continuous regular data is necessary for proper solid waste management.

Izmir is the third largest metropolitan city of Turkey with an area of 12,007 km². Located in the western Anaotolia on the Aegean Coast, the city is surrounded by the Aegean Sea. There are touristic and agricultural activities in some of its surrounding districts while people subsist on commercial, industrial, and educational activities in the city center. The population of Izmir is about 4 million and 4,000 tons of solid wastes are collected per day as an average value. The current study aims to present and compare the results of different solid waste composition and characterization studies conducted for the city of Izmir, in a time period between 1996 and 2015. The data used for comparison is obtained from the previous academic works conducted in Dokuz Eylül University. The increase in the population, development of the big supermarkets which decrease the use of open bazaar, the common use of natural gas in the housings, seasonal changes of the sampling periods are the main factors effecting the changes in waste composition and characterization. In addition, the variations in the sampling districts and areas can also be the reason of the differences found as well as other factors.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens - ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
