  The aluminium demand is increasing worldwide, so the amount of red mud, which produced during the production of aluminium, is constantly increasing, also. The researching of the economical processing of the byproduct has been under way for a long time, but the industrial implementation of recovery technology, that is suitable in all aspects, has not yet been realized. The use of by-products, in addition to reduce the risk of contamination of environmental elements, may be useful for the recovery of valuable metals, which contained therein.

• The Possible Job Creation and Job Destructive Effects of Technological Development

  Throughout history, technological change has often provided the basis for employee anxiety. Between 1811 and 1816, a group of workers in England who called themselves "Luddists" destroyed machines, because they thought it would endanger their workplace. 19th-century thinkers and economists such as Karl Marx and David Ricardo predicted that mechanizing the economy would ultimately worsen workers' conditions, depriving them of a decent wage. Over the last century, John M. Keynes (1930s) and Wassily Leontief (1950s) have expressed their fears that more and more workers will be replaced by machine solutions that will lead to unemployment. In recent years, Brynjolfsson and McAfee (2014) have argued that existing technologies reduce the demand for labor and put some of the human workforce at a permanent disadvantage. However, there are a number of compensation mechanisms that can offset the initial displacement effects of automation and process innovation in general (Vivarelli, 2015). First of all, while workers are being replaced in industries that introduce new machine technology, additional workers in new industries are needed. Second, automation (and process innovation in general) reduces average costs. Acemoglu and Restrepo (2017) found that this results, on the one hand, in the effect of price productivity (“priceproductivity”) (as production costs decrease, the industry can expand and increase labor demand); and, on the other hand, it leads to economies of scale in production (the reduction in costs due to automation leads to an increase in total output and increases the demand for labor in all industries). Similarly, Vivarelli (2015) argues that lower average costs can result in lower prices (if the industry's market structure is perfectly competitive), stimulate product demand, or result in extra profits (if the industry's structure is not perfectly competitive). If these extra profits are reinvested in the company, this investment can create new jobs. The presentation intends to present these counterbalancing cases and to provide real examples based on the literature.

  The nature of flaring processes has created a severe impact on man and the environment. Massive environmental degradation as a result of flaring activities has led to fluctuations in climate as well as depletion of the vegetation cover through acid rain. Findings have been made on some harmful gases released into the atmosphere that have effects on the environment and also on man. In order to control these effects by ensuring a clean atmosphere and environment, a new flaring model (DanMat flaring model) has been suggested. The model uses smoldering mechanism to reduce the amount of heat released into the atmosphere during conventional flaring by 60%. It also uses scavengers to oxidize harmful gas produced during flaring activities into less harmful ones. With this model one can flare gas without polluting the environment since it reduces the emissions of harmful gases during flaring.

  Generations Y and their expectations have caused many surprises for employers. They are different compared to their predecessors. Millennials were born in socialism in our country, but they did not experience from it so much, because they grew up in democracy. Their main feature is that they are openminded to opportunities, and they learn quickly modern technology innovations. They have a strong self-conscious, and are highly proactive. They prefer forms of atypical work, because they can carry out their work anywhere in the world due to the internet access. It is very important for them to keep the work - life balance. These properties have overwritten the conventional management methods, such as conventional recruiting techniques. This paper examines the main job seeking features of the Generation Y based on an empirical research.
