The Tisza is a river which connects five countries to each other and it has an enormous catchment area. Its longest section can be found in Hungary. Two million people live directly in the spatial environment of the river. The safety and favourable quality of life of these people have to be provided. This is a great challenge from the aspect of regional development, economic, technological improvement, the acceleration of innovation processes, as well as the establishment of natural and environmental harmony.

This situation is also deepened by the fact that the social and economic backlog increases in the majority of the region, as one third of the 33 most disadvantaged small regions in Hungary can be found here. This study basically contributes to the establishment of the development of the Tisza river’s spatial environment and the development of new solutions.
Power-to-gas (P2G) is referred to technologies that convert carbon dioxide into methane. Both bio- and chemical catalysts may be used for conversion purposes. One of the most disruptive biotechnologies was developed by the University of Chicago (IL) (publication number: EP2661511B1), using a robust, highly selective, patented strain of Archaea.... Electrochaea GmbH has developed an innovative bench-scale P2G prototype unit, which uses this highly efficient Archaea strain, specialized components and specifically developed control strategies. The structure and the components of the prototype are equivalent with the functional parts of the currently largest commercial scale biomethanation BioCat plant located in Avedøre, Denmark (www.biocat-project.com). Power-to-Gas Hungary Kft. has committed to further develop this innovative technology. The first steps of this development have been taken by operating the benchscale unit and analyzing the data of the operating periods.
The prototype is operated based on weekly campaigns. During continuous operation, H2O is generated as a by-product of methane. Therefore, approximately 200 ml of biocatalyst is discharged each day and concentrated media containing macro and micronutrients are injected into the reactor to maintain media composition. The laboratory staff records all gas composition data each morning. The gas composition is measured every 12 minutes by an Awite AwiFlex Cool+ gas analyzer. Within this article, we analyze the collected datasets containing more than 12 000 records and present the first practical experiences of the operations of the innovative power-to-gas bench-scale prototype.
The analysis of the collected gas composition data of the product gas already provides important data for modelling the commercial-scaled processes. The average value of VVD was about 40 l/l/d in the period under review. Further increase of the methane content can be achieved by introduction of higher mixing energy and by increasing pressure levels in the bioreactor (as demonstrated in the BioCat plant – data not shown here) – both of which are strategies envisioned for the commercial plant. In routine activities (turn on, shut down, continuous operation) we could verify the high robustness of the biocatalyst and the base connection between the registered datasets and performed test results.
The basic functioning of the world is mostly led by negative trends. One of the fundamental reasons for this phenomenon is that the different technologies (hardware, software, resources) do not act properly and in the proper structure by means of the produced products and services. Therefore, the examination of technologies and resources is a k...ey question of our world and development from various aspects. Technologies convey all positive and negative impacts which can be regarded as the fundamental reasons and causes of harmonious or disharmonious development. For this reason, the role of technologies in development and harmonious functioning is of paramount importance.
As a final conclusion, we established that the different technologies (hardware, software, resources) are interpreted as impact conveyors which predominate by means of products and services in a way that their relation system is determined. By using the thermodynamic interpretation which is the basis of the functioning of the world, we built a system consisting of 14 elements to evaluate different technologies, to interpret its functioning and to develop positive interactions and trends.
The question how economic, technological and infrastructural developments, as well as products and technologies contribute to the unity and constant strengthening of the society is still unanswered both in Europe and the whole world.
The current erosion of the society and the weakening social cohesion is a regrettable process. These phe...nomena are a barrier to real development processes and weaken the extension of the economic space; therefore, this negative process has to be stopped and turned into a positive direction.
For this reason, it is increasingly urgent to work out new, feasible solutions, since it has become obvious that solutions whose sole aim is to increase profit typically weaken the indispensable unity of the society, market positions, innovation processes, as well as natural and environmental harmony.
In this situation, we analysed and interpreted the disadvantaged and multiply disadvantaged microregional spatial environments, with special regard to the strategic developments that serve both the strengthening of the microsocieties of microregional spaces and the development of the economy and the extension of economic space.
The identification of disadvantaged microregional spaces is basically done by means of economic indexes, but it is also important to emphasise that these indexes can only be interpreted with social indexes, as they define the situation of the microregional space and the possible development directions together.
The constant strengthening of social unity (cohesion) and the related economic development is basically a new focal point and objective.
The control of our relationship with our environment is one of the greatest challenges of the 21st century. This has an effect on the economic and social processes and the human activities. All of these are included in a new developmental strategy: the strategy of sustainable development.
The strategy of sustainable development prevails by t
One of Europe’s largest bioreactors has been established in Nyírbátor in Hungary at first (chief executive: Mihály Petis).
The North Great Plain region is one of the backward regions of Hungary. The low level of economic development is mainly due to the lack of industrial development. The region is poor in natural resources, its main resources are land, natural gas fields, carbon dioxide, thermal water and the clay mineral stock.
The structure of GDP per capita
The proportion of the industry and the building industry is not significant. Of the various service provider sectors, trade, transport and telecommunications have a small proportion, while financial and economic service providers have even lower share, which is due to the fact that these sectors are mostly concentrated in Budapest. The share of public and human service prodivers is higher than average due to the University of Debrecen.
The GDP which expresses the economic development of the county in a complex way increased four times its previous value in nominal value between 1995–2009. However, if the real value is considered, the increase is less than 25%, as opposed to the country average, which was less than 40%.
The most complex index of the development level of an economy is GDP expressed either in nominal or real value. If expressed in dollars, GDP is suitable for international comparison with the correction based on the purchasing power parity per person.
The county represents 4.3% of the people employed in the industrial sector in Hungary, while its share in industrial production is only 3.3% which is lower than the regional and population share of the county within Hungary. As regards industrial production per person, Hajdú-Bihar was the 10th county in Hungary; therefore, it is considered to be a less industrialised county.
The product structure of GDP is suitable for drawing useful development conclusions, but the result is more reliable if the income creation ability is also analysed on the basis of the employment structure.
The essay describes the rural system of areas as a system unit of mutually necessitating natural, social, economic and human environments. A new rural developmental model has been developed to achieve the effects that strengthen this system. The taxonomically interpreted effects are achieved through guiding projects. The author presents the con...nections of biomass – bioenergy generation to covey the message in practice.
An increased expansion of renewable resources and biodiesel is observed and prognosed, since fossile energy resources are about to run out. Hungary achieved outstanding sunflower years in the recent years in worldwide comparison. In the future, the feedstock of biodiesel production can also be rape besides sunflower.
According to the concept
disadvantages of biodiesel production in different environments, using a model to do so. In order to maintain the harmony, the existing resources have to be managed properly, taking the correlations of the system into consideration. Targeted technological developments are necessary, similarly to the improvement of energy safety and efficiency.
The transformation and utilization of organic materials must occur with the highest degree of environmental conformity. This conformity – in accordance with the guiding principles of the European Union – will result in a new economic and systematical approach.
