Abstract

Disasters like earthquakes can cause severe damage and impacts, resulting in a significant amount of waste. A massive earthquake hit 13 cities of eastern Türkiye, on 6 February 2023. The aim of the study was to estimate waste generation and suggest a waste management strategy in cities affected by earthquakes. Earthquake wastes were estimated based on two distinct gross areas (120 m2 and 150 m2) and unit area weights derived from on-site investigations (1 t/m2) and obtained from the Great East Japan Earthquake data (1.107 t/m2). The estimated maximum amounts of earthquake waste generated in the cities that were mainly affected by the earthquake will be approximately 54, 23, 17 and 14 million tons in Hatay, Kahramanmaraş, Malatya and Adıyaman, respectively. The amount of earthquake waste in these cities will be ~39 to 71 times higher than the annual municipal solid waste amount. The total amount of earthquake wastes from the region will be between 100-138 million tons which is 3-4 times higher than the annual municipal solid waste amount of Türkiye. The generation of such a large amount of waste in a short time brings difficulties in the management and in finding landfills. Therefore, additional help provided from the other municipalities and the government. Separation, reuse, recycling and recovery of earthquake wastes should be ensured by applying circular economy principles. Then, the remaining wastes should be sent to landfills.
