Waste inventory for a refrigerator manufacturing plant

Dönmezoğlu, Cansu
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.

Increasing population demand has triggered the enhancement of food production, energy consumption and economic development, however, its impact on climate change has become a global concern. This study applied a novel environmental sustainability assessment tool using dynamic Autoregressive-Distributed Lag (ARDL) simulations for model estimation of the relationships between greenhouse gas (GHG) emissions, energy, biomass, food and economic growth for Australia using data spanning from 1970 to 2017. The stud...
Application of the contingent valuation method in a developing country: a case study of the Yusufeli Dam in northeast Turkey
Alp, Emre; Yetiş, Ülkü (IWA Publishing, 2010-01-01)
Hydroelectric power plants and dams often play an important role in developing countries in terms of their contribution to economy. In accordance with the energy policies of Turkish Republic, Yusufeli Dam and Hydroelectric Power Plant in Northeastern Turkey have been initiated. In this study, the Contingent Valuation Method (CVM) was conducted in Yusufeli Village to determine the environmental costs of the Yusufeli Project. The purpose is to assess the willingness to pay (WTP) of Yusufeli Village residents ...
Evaluation of state owned indigenous coal fired power plants including coal reserves
Güler, Mehmet; Güyagüler, Tevfik; Department of Mining Engineering (2010)
Fossil fuels has preserved their importance in gradually increasing production and consumption of both energy and electricity of the world. Asia, especially China and India, has arisen new actors of the sector. Energy and electricity consumption of Turkey has also increased in parallel with her economic development, but due to her limited resources, she has become more and more energy dependent in order to meet her growing demand. Although hard coal is only found around Zonguldak region, with its abundant a...
Mathematical modelling of geothermal carbon dioxide production in a specific field in Turkey.
Kumsal, Beril; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2020)
Turkey’s non-condensable gases production from geothermal fields is very high when compared to other countries’ average production values. A big predominance of these gases is generally carbon dioxide (CO2) and the origin of this CO2 is generally meteoric for the studied area as reservoir rocks are carbonate-dominated metamorphic rocks such as dolomitic marbles and marbles.The dissolution of calcite mineral within the reservoir rocks, where it equilibrates with water, results in CO2 release from the system....
Vulnerabilities, Threats and Gaps in Food Biosecurity

The food production system throughout the European Union, which includes farm production, harvesting, transport, processing, storage, marketing and consumption, is vast, complex and open. The high volume of trade in fresh vegetables and fruits contributes to the vulnerability to contamination, whether by accident or intent. Outbreak investigation is critical to understanding the sources of contamination and the steps required to minimize it. The fact that much of the trade in these commodities is internatio...
