Description:
Plastic waste is one of the biggest problems facing our planet. From mountains to oceans, it pollutes our environment, can affect human health, and destroy ecosystems. While global plastic production was 1.5 Mt in 1950, by 2021, it will have risen to 390 Mt. Plastic products have an average lifespan of 10 y but can take up to 500 y to degrade. Not all people can be persuaded to do an activity immediately, even if the activity is genuinely beneficial or useful to society. An example is the case of plastic waste that the public can collect in the plastic waste recovery process. This is a critical point in the process, which needs to be taken in several directions to facilitate. The aim of this research is to develop a disruptive proposal for an innovative solution for the mandatory packaging return in Hungary with domestically developed recycle vending machines. This study outlines several possible solutions, such as multifunctional recycle vending machines, their placement at strategic locations, the use of innovative technologies, and the implementation of environmentally friendly operations at the design stage. The proposals set out the user requirements for the whole system and the steps needed to implement it in society.

Description:
Analysts often treat the circular economy as a technical issue. They often focus on how to organise work processes better. The authors’ concept is that circularity is much more than that, and a more precise and holistic approach can help create a better and more inclusive future for all. Young people play a key role in achieving a circular future (as a socioeconomic system). In this paper, the authors will look at how young people relate to circular processes. The research, based on a survey of 1,442 university students, took place in November and December 2022. The majority of the respondents were born around 2000 and are enrolled in undergraduate studies at Széchenyi István University. The questions of a standardised questionnaire were designed to collect information on the awareness of participation in the socioeconomic cycle process, the understanding of the context and the way of participation. The results of the research show that the students who consider themselves environmentally conscious are more likely to recycle and collect waste selectively, but it is not clear whether they participate in extending the life of the objects (swapping, second market, etc.). The research also found that students do not use and are typically unaware of online applications promoting circular lifestyles. The research sheds light on what a circular future would look like and what could be built on it.
After the Hungarian transition, the joining the EU and by the employment agreements among the European countries the west-wards migration brisked up. The high unemployment, the marketable professions and knowledge of languages helped the qualified experts to emigrate for better job and salary or prestige into the western European countries. Researching the Hungarian migrant potential it is verifiable; learnt material/occupancy and knowledge gained in Hungary almost lost as the employees that migrate, do not strive to get a job in accordance with their knowledge but in case they do so, it is without success. The brain waste tendency and underemployment is to be mentioned better, than the brain drain in case of the Hungarian high-skilled (BA, MA) employees obtaining a job abroad. This study is about to reveal the problems of mentioned above and this study is supported by the result of the survey made in the EU-15 among the Hungarian economics graduated migrants, examines the causes and in the focus there are the migrant motivations of the high-skilled young generation after the crisis. The survey's period is 2012-13 and it was carried out in a form of a questionnaire.
