    The undiminished development of air traffic has a direct effect on the environment of airports. Year in year out the continuously growing passenger traffic has increased the number air flights. The technological development has made it possible to increase the size and performance, - and with it the transportation of heavier payload - of aircraft. Of course, it has necessarily resulted in more fuel use (burnt fuel) emitting more pollutants into the atmosphere. In addition this effect appears not only during the high altitude flying polluting the high atmosphere, but due to the today very busy and the continuously increasing ground aircraft motion (taxiing) contaminating the close surroundings of the airport. With some innovation and technological development we can make the airports not only more environmentally friendly but also cost effective. In this paper I would like to introduce the possible use of renewable energy sources and the ground movement of aircraft without their own engines.

    Today, unemployment is caused by environmental and economic changes are burning quite a problem around the world. With startups over the past 10 years, the economy is showing more and more increasing trend, so why not make it against the climate change fight, even while the young entrepreneurs also support the economy. There are many things to do, which is still untapped, including the use of geothermal and renewable energy resources, which not only
    reduced dependence on foreign countries, but also new jobs could be created using environmentally friendly methods. The innovative emerging entrepreneurs’ maybe will soon find a solution for climate change, because this phenomenon is certainly all the inhabitants of the earth directly or indirectly exercise influence.

  • The comparison between the environmental performance index of the wood-gas as an alternative fuel and the life cycle assessment rate of the lpg, and gasoline-powered vehicles

    This paper presents the Life Cycle Assessment of the wood gas powered car. I have compared the results with the data of the gas powered cars. The wood gas powered cars will be presented from their invention up to this day. I will describe in detail the chemical composition of different types of trees, the heating value and the reaction equations of gasification. I have made a cost analysis and I have concluded that if wood gas is used as petrol, the costs can be reduced significantly.

    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).

    In the 21st century is a difficult task that just completed a tertiary education institution whether it can be college or university. The theoretical part of the school to learn their profession, but it is possible that the future work over the years to acquire the practice. Environmental and agricultural development specialists’ undoubtedly great expertise, which is great emphasis on research, and the resulting innovation that is present several areas. With the new technologies work more effective, energy efficient and become more conscious. By a recent graduate professionals startup business can achieve even greater success, not only in his country but also abroad supports not only the Hungarian economy by this, but also enhances the reputation of the country. Institution of higher education in the region Szolnok completed by 100 persons completed a quantitative research, which is very interesting information can be obtained.

  • The effect of the sporulated bacillus to the increase of the tomato and its yield

    Tomato contains high concentrations of lycopene and vitamin C that is important elements of healthy foods. In intensive production, many biotic and abiotic stress-factors are affecting the tomato, and they might be harmful also to the environment. Due to these pollution problems people are highly interested nowadays in the limited use of the agro-chemicals. Among the beneficial microbes, bioeffector (BE) microorganisms are used frequently in sustainable crop production. Bacillus strains can mobilize the hardly available phosphates in the soils, and therefore they can reduce the harmful effects of abiotic environmental stress factors. A bioeffector, containing Bacillus amyloliquefaciens FZB42 strain was used with tomato test plant (Solanum lycopersicon Mill. ’Mobil’) in pot and in field experiments. The length and weight of shoots and the weight and number of tomato fruits were tested in a biweekly periods. The treatment had positive effect on the length of shoots, the size and biomass of fruits both in the field and in the pots. Less beneficial impact was realized, however at the diverse ecological field conditions than at the controlled light chamber. Application of the Bacillus bieffectors can be helpful for the organic production of the tomato.

    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 hand 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.

    Aviai on is the quickest and most praci cal way of locomoi on, to which people have been paying at eni on for thousands of years. Today – on account of air traffi c, energy crisis and environmentalism – the power source of the aircrat became a key issue. In addii on to fl ight safety, there is a growing emphasis on environmentally friendly operai on. The ineffi cient burning of fossil fuels comes hand in hand with the signifi cant pollutant emission and noise pollui on which bother even those living far from the airports. Nowadays the most important objeci ve of researchers and developers is to create an effi cient, clean and quiet airplane, thus as a new idea they at empt to ui lize electricity in this form on board the aircrat . The ari cle presents some various energy resources through some example of unmanned aerial vehicle.
