Arguments for the optimisation of using biomass for energy production
103-108Views:163Using biomass to produce energy is not a new idea. In the past, the by-products of energy(?) production processes or naturally grown materials were mainly used for energy production. At the same time, during the production of biomass the conventional sources of energy are used (fuels, the embodied energy of which is used in the production of the biomass and equipment, etc.) which must be taken into account when determining the net energy production. This research aims to examine how to optimise the production and use of biomass energy and its supply chain in the energetic and economic criteria system, as well as how to impact upon the managing models of the processes to the energetic and economic parameters of the supply chain; we ask what criteria characterise the natural (environmental), economic and social sustainability, and how they can be implemented e.g. within the framework of an innovation cluster. This article describes a test model, and analyses the results of the model examinations and the conditions for compliance with sustainability criteria. Arguing the environmental, economic and social sustainability among the criteria of the model for evaluation is not possible at all times by means of direct indicators. The results of the research proved that only multi-criteria optimisation models serve a proper decision-making instrument for the evaluation of biomass utilisation for energy production.

The examination of the profitability and competitiveness regarding the energy plantations of woody plants in the region of Észak-Alföld
5-11Views:145Due to the decrease in the quantity of traditional energy sources, in the future an alternative energy production should be sought which provides minimum environmental burden and offers an opportunity to generate energy. The use of biomass provides another option to resolve this problem. The most important features of the biomass are that the quantity doesn’t decrease during conversions and are reproduced by natural processes. The main raw materials of the biomass are considered to be the energy plantations, which are economic in areas where the farmer, during the traditional production, can’t or with difficulties can cover the expenses, so that profitably sustainable cultivation branches can come to the forefront with less material and energy input. Those cases in which the cultivation of agricultural areas are not economically feasible, there is a possible utilization in our country which is the installation of plantations with energetic aim.

Bioenergy: Risks to food-, energy- and environmental security
121-130Views:256There are growing opportunities and demands for the use of biomass to provide additional renewables, energy for heat, power and fuel, pharmaceuticals and green chemical feedstocks. However, the worldwide potential of bioenergy is limited, because all land is multifunctional, and land is also needed for food, feed, timber and fiber production, and for nature conservation and climate protection. The recent expansion of the bioenergy industries together with a strong increase in many commodity prices has raised concerns over the land use choices between energy needs and food and feed. New systems of energy production must be developed based on cost of environmental damage due to production and use of fossil energy and certain chemicals and materials. This article presents risks to food and energy security, estimates of bioenergy potential and the challenges of the environmental and social impact associated with expansions in bioenergy production.

The possibilities of energetic applicability and economic evaluation of grape in the Szentantalfa township
25-32Views:126Energy production has become one of the key problems in the recent years. Hungary is lacking fossil fuels, but could play a leading role of biomass utilization in Europe. In the concept of biomass not only main-, but by-products (e.g. grape) are be included. Since farmers face a variety of difficulties in disposing of garpe from plantation sites it would be beneficial to encourage grape use in energy production. In our opinion due to varying transportation costs it is crucial to investigate the amount of potentially usable grape both for the whole country and in local township levels. Our economic studies were done on the Szentantalfa Township’s Balatonfüred-Csopak Vine Region. According to our findings the total amount of grape generated in the township theoretically amounts to 5.28 TJ exploitable that would operate a 360 kW boiler for a whole heating period (6 months). In our opinion the appearance of local energy production based on grape could significantly raise the ability of the future potential income of townships.

Plant production for biomass into energy: economics and energy efficiency view
65-71Views:163The aim of the paper was to determine the influence of the fertilization level on the energy and economics efficiency of the production technologies of selected crops processed into bioethanol or biogas. There were investigated the following crops: rye, triticale, wheat, sugar beets, maize, sorghum, reed canarygrass and Virginia fanpetals. In the energetic efficiency the Energy Return on Energy Investment index (EroEI) was used. Apart from the ERoEI ratio, the Net Energy Value (NEV) ratio was also used. In the economics efficiency attitude, the Gross Margin (GM) was determined.The investigations proved that in general, the production technologies of crops where the lowest levels of nitrogen fertilization were applied proved to have the highest energetic efficiency. The highest economic efficiency was characterized by the production of corn for biogas. In the case of the production of bioethanol (all plants), ratios were on the verge of profitability or the lack of it showed.The analysis proved that the efficiency of the technologies of production of the crops to be processed into biogas is several times higher than the energetic efficiency of the technologies of production of the crops to be processed into bioethanol.

Renewable energy resources in Hungary – solid biomass utilization in terms of necessity and opportunity
75-78Views:155In the 21st century a country’s success significantly depends on how it can solve the problems (supply safety, growing prices, climate change, etc.) induced by the application structure of the fossil energy sources with the means of energy saving, energy efficiency and the utilization of renewable energy resources. The utilization of renewable energy sources has positive effects on five key areas: environment protection, energy policies, fulfilment of EU expectations, agriculture and rural development and on the whole of the national economy. The bioenergy – beside fulfilling the national economic aims – it is putting up the value of the role of agriculture and rural development. The role of agriculture is multi-functional in the process. The agricultural sector has an important task in the area of bioenergy to ensure the proper quality and quantity of raw materials for the increase of bioenergy utilization. This also means new sales perspectives and opportunities for the producers. Above all this, the agricultural policy aims for the agriculture and the rural development segment to be the unambiguous winner of the new bioenergy sector and for most of the available profit to stay with the agricultural sector, with the rural players. For this reason encouraging the raw material production it wishes to encourage the producer their primary process and their local utilization. One of the fundamental objectives of the measures is that agriculture should go beyond the raw material production and take steps towards processing and utilization. The multifunctional role in the product chain might mean extra income and more added value for the producers and the active players in the process. The other objective is to promote the local utilization, the scatter of the environmentally friendly energy sources in rural areas, to change the energy is “lying on the ground unutilized” principle while local processing and promoting the utilization, to achieve a lower energy dependency and to optimize and disseminate cost efficient solutions. To realize all this means a great task and a huge challenge for the agricultural government as well as the rural societies and micro regions but might lead to a successful rural development. The range of the tools and measures to fulfil the aims might be very broad, from the regulating instruments to the various subsidies, coordination and dissemination tools. Part of the subsidy schemes are direct production-type of subsidies (the so called direct payments, for example the area based subsidies) and the other main forms are the investment-type subsidies which are for technology development, promotion of competitive production and local processing and for establishing a green energy industry. In the period of 2007-2013 the key elements of the development schemes were drafted in the frame of the New Hungary Rural Development Programme (ÚMVP) and the Environmental Energy Operational Program (KEOP). The available raw materials and the conditions are taken into consideration while designing the development schemes because a successful realization of a product chain means the assurance of the inputs and outputs. The starting point of determining the development direction is the principle of an operation which is sustainable and economical on the long run. In addition such developments are considered reasonable which are viable on medium and long term and bring numerous rural development, environmental and societal returns.

Price risk management using by a specified futures model
97-101Views:104The principal achievement of this paper is to introduce the operation of a specified ‘Futures’ model and it’s practice for decision makers of financial institutes through an example based on the price data’s of grain futures market from EU assessment 2004 to these days in Hungary. Based on a theoretical foundation, the calculation model was developed in order to assist short and long-term marketing decisions. The economical basis of the model is the combinative use of two market institutions: public warehousing and futures market. This electronically developed and working model ‘using excel background ‘allows all of the participants of the market: producers, consumers,banks and traders, to use this model in immediate calculations. In addition it helps in order to establish the own business strategy. The model can be used to analyze price influencing factors therefore; it can also be used for policy-making decisions for market participants as well as banks dealing with trade financing activity.

Knowledge and acceptance research of use of vine-branch in micro region of Gyöngyös
117-119Views:137Significant quantity of renewable plant biomass comes into existence in Hungary year by year. Nowadays there are different wellknow possibilities for utilization. However these methods are not widely accepted. The most important obstacle is frequently caused by lack of knowledge of farmers. Without the necessary information the farmers become distrustful, and in many cases significantly decrease the efficiency of reclamation. Targeted communication method should be used to improve the rates of utilization. It should include appropriate content to their knowledge. This study research the knowledge and the acceptance of vine-branch utilization circle of wine-grower in micro region of Gyöngyös by questionnaire survey. We will know why the use of by-products has not spreaded yet circle of wine-grower and where they get their information from. The typically fragmented farms do not utilize because they do not know the process for doing or other people cultivate their vine-yard so they have not necessary machine. The questionnaire ask the farmers they want to offer their vine-branch a user factory.The questionnaires was completed by personal request. The reason of methods was the bigger rate of query. The questionnaire include question about the farm, the use of vinebranch and data of farmers. The villages were asked the rates of wine-grower. The aim of the research the rational utilize of by-product by wine-growers year by year. With the results of questionnaire survey we can inform the farmers with the appropriate method about the necessary knowledge.
