Abstract
In Turkey, control studies related to the wastes from ships continue, and the first waste acceptance facility (WAF) from ships was founded in Istanbul: Haydarpaşa WAF. Haydarpaşa WAF has been accepting waste since September 2005 based on the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78). The number of transit ships and their disposed wastes have been continuously recorded in a database since September 2005. The main goal of this study is to forecast the amount of different waste collected from transit ships for next two years based on the data recorded between September 2005 and January 2010 using ARMA forecasting model. According to result obtained with the model, the current data remain between the upper and the lower limit values of forecasting data.
