The possibilities of companies how to reduce their emmisions
Published August 6, 2020
61-68

The sustainability and its key element, the environmental awareness has been known for decades, however in general can be said that in the decision making the short term economic profit is still more dominant both on the individual and company levels. In last few years the rapid growth of CO2 emission is now not just risking the human life but ...the flora and fauna is in heavy danger. The concerns pay more attention on their short-term profits instead of the environmental protection. First of all with the change of the leadership attitude can reach the environmentally conscious organization that can support the reduction of the emissions, so the improvement of the atmospherical CO2 concentration. In my study I’m going to present what possibilities do the companies have to reduce their emissions and how these improvements could be harmonized with the profit interests (with the reduce of electricity-, water-, and gas consumption).

THE ORIGIN OF ECO-ETHICS
Published August 21, 2020
57-63

Technical and economic professionals have to expect serious challenges if they want to take the insurance of the sustainable development of the natural environment into co nsideration. Apart from the professional difficulties they especially have to prepare for the fact that mainly the proponents of ecology make their work difficult. They have ...to hold their ground in the field of force where the politicians of green organiza tions and the environmental science are dead set
against each other. Further on we do not intend to get entangled in this incoherent system of relations. We would rather look into its ethical connections and the history of its origin.

Skills related to EU Projects
Published August 21, 2020
113-119

Our country with its accesion to the European Union in 2004 became eligble to use EU funds for its national developments. More than 7,8 billion Ft had already arrived in Hungary during 2007- 2013. The allocation and the use of EU funds represent a unique and never returning oppurtunity but also a great responsability for Hungary. While infrastr...uctural projects (e.g roads, urban rehabilitation, fulfillment of derogation obligations) has dominated the 2004-2006 and 2007-2013 periods, the Széchenyi 2020 National Development Programme focuses mainly on economical development, 60% of the 8 200 billion Ft allocated EU funds will serve the cause of reviving and boosting the economic growth. Besides this, environmental protection, employement, innovation and the knowledge economy will represent also main focuses for the use of EU funds in Hungary. Where ever we look we see the the multitude of results of EU funded infrastructural, human, and research projects. In the 2014-2020 period even young professionals graduating from Szolnok College will be able to become potencial applicants for EU funds. During the course „Projects, from application to materialization” iniciated within the Bethlen István Specialized College
students were able to get acquainted with the basics of project writing, project terminology and project management.

Vermicomposting of communal sewage sludge
Published August 6, 2020
52-60

The proper management of communal sewage sludge is a priority aim in today’s environmental protection. Among the possible technologies one environmentally sustainable sludge treatment technology can be the vermicomposting of communal sewage sludge. Before the successful operational level vermicomposting is absolutely necessary to investigate ...the process of vermicomposting in laboratory controlled conditions. In our studies vermicomposting of communal sewage sludge was carried out by comparing two earthworm populations in laboratory. During 6-week experimental period the temperature (with soil thermometer) and the redox potential (with ORP portable device) were measured every other day. The weekly, measured, basis parameters were the compost visual appearance, color and smell, pH (H2O), dry matter content, organic matter content, EC (conductivity), from which the total salt content can be calculated, total nitrogen content, phosphorus content (P2O5), potassium content (K2O), calcium and magnesium content, humus content (H%), determining the humus quality according to Hargitai’s method and dehydrogenase enzyme activity. It can be concluded from the results that the vermicomposting of studied communal sewage sludge has started and keeps going. The basic physical and chemical parameters (e.g. temperature, humus quality and quantity) support the changes. The results of humus quality and quantity which are priority variables of agriculture use show average increasing despite the initial recession. The changes of the important chemical parameters (nitrogen, phosphorus, potassium) in nutrient management were developed favorably. In our presentation the previous laboratory results are described.

Trends in the Construction Industry and in Building Public Utilities
Published August 21, 2020
23-28

If one hears the word construction industry, one probably associates it with building a house, but the concept of construction industry covers a much larger area and can be divided into colourful periods. Architecture is the transformation of the built environment. On the one hand it is one of the branches of arts (applied arts), on the other h...and it is one of the branches of engineering and technology disciplines. Nowadays, more and more environment-friendly technology is used in the construction industry, and already in the design stage a considerable emphasis is put on the use of renewable energy resources, in particular the use of solar cells. To measure the trends in the construction industry and in the building of public works we have also prepared a questionnaire which was filled in by 100 managers of enterprises.
