Solid wastes are generally collected without being recycled and are generally disposed of through irregular storage in ou rcountry. A very few part of precious materials in solid wastes are being recycled, whereas the remaining part is being buried into the soil. Therefore, a potential economic value transforms into a potential source of contamination. Based on this fact the aim of the study is to handle solid waste management practices in the context of İZAYDAŞ example, which is the Turkey’s first waste disposal facility and located in Kocaeli. Within the scope of the study, the approach of the municipalities to the solid waste problem was evaluated in terms of economy and environment. In this direction, within the framework of the İZAYDAŞ example, the data of TUİK were analyzed and the solid waste management practices of the municipalities were examined and the situation was determined. As a result, it was determined in the study that İZAYDAŞ waste incineration plant, which started its operations in 1997, is an important facility that enables the disposal of wastes from both Kocaeli and the country and their transformation into economic value in the process from garbage disposal to waste incineration. In addition, the necessity of determining whether the waste management policies implemented by İZAYDAŞ have risks or not has been revealed.
