European Union published IPPC Directive in 1996 aiming to create an integrated approach in order to manage and control industrial facilities better. IPPC provides the development of a new concept of “Best Available Techniques (BAT)”, the most effective, advanced and applicable methods, preventing emissions to the environment and providing efficient use of resources. Within this framework, numerous sectoral Best Available Techniques Reference Documents were published giving information on the sector and BAT alternatives for this sector. Iron and steel industry, which causes quite significant amount of resource depletion and waste production, is one of the industries within the scope of IPPC Directive. In the this study, environmental performance of an integrated iron and steel plant in Turkey is evaluated and compared with the EU’s integrated iron and steel plants, in order to suggest applicable BAT alternatives for the studied plant. Totally 74 BAT alternatives were evaluated and among them 36 alternatives were determined to be applicable for this plant. Finally, two of these applicable BAT alternatives were selected and compared by use of cross-media effects and financial analysis. The results of this study indicated that dust emission and high energy consumption are the common problems in the facility. Moreover, sintering process was found to be the least compatible sub-process with EU’s iron and steel plants. Additionally, it was determined that with respect to application of BAT alternatives, facility is quite compatible with EU’s iron v and steel plants. Furthermore, cross media effect and financial analysis revealed that the selected BAT alternatives, “Advanced Electrostatic Precipitator (ESP)” and “Bag Filter-combined or integrated reduction of solid and gaseous pollutants”, have different cross media effects on the environment, however, the second alternative is a more cost-effective alternative than the first one. Since this study was undertaken in an integrated iron and steel plant that represents Turkish iron and steel industry with respect to its production process, production capacity and environmental performance; the results of this study can be used to aid decision makers to make environmental initiatives in iron and steel industry in Turkey.

Improvements in energy and water consumption performances of a textile mill after bat applications
Kocabaş, Ayşe Merve; Yetiş, Ülkü; Department of Environmental Engineering (2008)
European Union’s Integrated Pollution Prevention and Control (IPPC) Directive forms a comprehensive framework for industries mentioned in the Annex 1 of the Directive concentrating on the reduction of the environmental impacts of the industrial activities which can be implemented by the BREF Documents that provide guidelines for each sector. Among those industries, textile is a water and energy intensive one. In the present study, gains in terms of energy and water consumptions were assessed in a denim prod...
Security Sector Reform: Defence Reform in South Sudan between 2005 and 2013
McLean, Fiona; Baracco, Luciano; Political Science and International Relations (2018-4)
The internationally dominant framework for Security Sector Reform presents an integrated, holistic approach to national security sector management that claims to deliver, through international donors, a system for conflict-prone countries that will contribute to the stability required to enable sustainable peace and development. Security Sector Reform policy explains how a prescribed methodology, based on liberal democratic principles of good governance, contributes to long-term conflict prevention by addre...
Improving Building Performance of Higher Education Buildings, Involvement of End Users
Gooding, Luke; Erdogan, Bilge; Gürsel Dino, İpek (2019-04-20)
The importance of end user participation within the development of a design for building improvement is accepted and recognised. It is nonetheless a significant challenge to select the best approach for the engagement of users to produce effective design process contribution. This paper assesses the suitability of early stage qualitative end user engagement in enabling the design process. In particular, the paper reports on the case application of this early stage approach to make design decisions, in t...
Global Migration From the Eastern Mediterranean and Eurasia: Security and Human Rights Challenges to Europe (GLOMIG)
Ayata, Ayşe(2008-3-31)
The main objective of this project is to foster international cooperation between the EU and the INCO countries by organising workshops, forming expert groups, and providing policy recommendations to officials and other stakeholders on global migration. The project focuses on the Western Balkans; Caucasus; Russia, Eastern Mediterranean and Turkey. More specifically, the project aims to contribute to the European Research Area through the creation of a common platform. It will enable interested parties from ...
Smart Specialisation and RI Policy Framework in Turkey
Erdil, Erkan (IGI Global, 2018-01-01)
The smart specialization strategy (S3) has been accepted as a solution for the European Union (EU) to catch up United States in productivity, R&D intensity, etc. The process of research and innovation strategies for smart specialization (RIS3) is described in six steps: the regional/national context, governance, elaboration, identification of priorities, the definition of coherent policy mix and action plan, and finally, the integration of monitoring and evaluation mechanism. In this chapter, the situation ...
