About the Concept of the Environment Recycling—Energy (ERE) in the Romanian Steel Industry
This paper takes as its starting point an analysis of the ecological functioning of the electric arc furnace (EAF). Thus, we present a classification of emissions generated by EAF, including limits of variation in chemical composition of “dust” issued by EAF in various countries and limit values for permissible concentrations of these emissions.The paper presents and analyzes various abstraction and treatment-related emissions for hipo-polluting operation of EAF. In this chapter, the correlations between macro system represented by metallurgical environment and interacting systems: System-Energy-Recycling Environment (ERE), Ecological system (ECO), and Recycling, Reclamation System (REC-REV) are presented. These correlations are presented in the spirit of sustainable development concepts (DC) and total quality (TQ).

Research and Devolopment about Metallurgical Industry of Romania
Our chapter wishes to be a critical and reasoned radiography of the evolution/involution of metallurgical industry in Romania during the period 1990–2016. The importance of metallurgical industry, for any state, is obvious and overwhelming. In this context, paraphrasing a known dictum, we can strongly say that in the industrial environment and in life generally ‘if there is no metallurgy, nothing is!’ The structure and content of our material is logical one and evolutionary. So, we firstly present in order a description of the main metallurgical companies in Romania (companies in the steelmaking industry: COS Mechel Targoviste, ArcelorMittal Galati; companies from non‐ferrous metallurgy: Alro Slatina, CupruMin Abrud; metallurgical companies in the manufacturing and assembly industry: Metalurgica Aiud, Timken S.A Ploiesti). In Section 3, we describe critical components concerning the involution of steel industry in Romania. Thus, we analyse: benchmarks, restructuring of the steel industry in Romania, the impact of the global crisis on the steel sector in Romania, privatization, modernization/restructuring and monitoring between 2004 and 2008. In Section 4, we present the prospects of metallurgical industry in Romania, and in Section 5, we present technical‐economic components specific to the industry of metal materials.
