Household appliances production, especially refrigerators, has an important share in the economy of many countries in the world and Turkey. Yet, waste production during production constitutes a problem that should be managed. For that purpose, it is important to identify the wastes from production and evaluate the environmental performance based on these wastes. In this thesis, production processes in a refrigerator manufacturing facility in Turkey are examined. Hazardous, non-hazardous and packaging wastes arising from these processes are identified to make a waste inventory for a refrigerator manufacturing company. According to the inventory study based on field study and data covering a production period of 5 years, it was calculated that 75.3% of the total waste produced was non-hazardous wastes. 23.9% of the total waste amount was packaging waste and remaining 0.8% was hazardous waste. The mass balance study carried out for the production area revealed that 0.0445 kg of waste was generated for 1 kg of materials entering into the system for refrigerator production. Additionally, it was determined that the main sources of scrap cost, which mainly constituted of non-hazardous wastes, were assembly lines, mechanical processes and dyeing processes. Environmental performance of the refrigerator production facility, including waste recycling rate and waste generation intensity, was evaluated through comparison to the figures declared by other leading household appliances manufacturers. Best Available Techniques (BATs) alternatives were proposed which could be applied in the facility to improve environmental performance. As this study was conducted in a refrigerator plant which used typical refrigerator production processes and relevant process waste streams, results of this study can be used by other refrigerator manufacturers as well. ypermethrin, Alpha-cypermetrhin and Dichlorvos contribute to diffuse pollution loads causing the exceedance of EQSs at the Tersakan Creek. Furthermore, additional calculations were also performed to estimate the required maximum pesticide application rate not to exceed EQSs.
