A. INTRODUCTIONEnergy Security Union (ESU), an Austrian non-profit organisation, started off in 1991 with the motto: "Atomic or Sunrays", to close the natural nutrient gap. Even though atomic power plants are still in vogue in many developed and developing nations, biogas technology is gradually taking over in certain areas of our daily domestic requirements such as production of sustainable energy, clean water, air and soil vitalisation.ESU was one of the pioneering organisations that saw the potential for production of energy from organic waste and other trash and evolved a system to put it into best use for production of energy. Till date ESU has succeeded to a great extent in focusing public interest on the economical and ecological advantages of biogas fermentation plants which could help keep our environment safe and clean while at the same time helping households, communities produce the energy for various requirements. Today, ESU works in the areas of biogene wastes - fermentation plants - energy production - fertilizer production - soil texture quality increasing - water and atmosphere purification. We are fond of the fact that Austria's University of Agriculture is presenting the results of ESU's fermentation project as trend setter at international seminars. B. AIMS & OBJECTIVESThe major aims and objectives of ESU are as follows:
C. STATE OF THE ART - PYRAMIDIC FERMENTATION PLANTIn line with its stated aims and objectives to maintain a clean environment, ESU is proud to present to the public at large its newly patented fermentation plant.ESU's fermentation plant with sedimentation device for thermic and pyroenergetic hygenisation is equipped to split the solid, liquid and gas forms present in biogene wastes and thus produce water, energy and nutrients separately. This triple-effect mechanism is considered a great boost to economies of rural and urban communities, especially in the developing nations where financial resources are a major hindrance towards industrial utilisation of the naturally available resources such as bio-wastes for the production of water, energy and even nutrients. It is also one of the most and safe fermentation plants meeting all international standards for biogas production plants. ADVANTAGESCompared to other forms of regenerative energy production methods, biogas production is highly recommended because of it's added advantages of atmospherical stress decreasing.Another major advantage is that the waste which is normally in the rotten stage, is used within a closed circuit and the methane gas is burned completely for electricity production. Furthermore, the fossil energy sources are substituted and aerobic process, which generally stresses the atmosphere in other processes are avoided. In other words we are also advocating an environmentally safe processing technology. The biogene wastes, manure and as a logical consequence, special plants and fibres for energy production indeed harbour a never ending potential for environmentally friendly energy. A major advantage of the biogas technology is its inherent ability to solve the "nitrate-problem". This is carried out through area covering implementation of the biogas plants which refine fresh (cattle) manure. In this respect one also has to bear in mind the disadvantages of fresh manure fertilizing. Another advantage directly benefits the farmers. By fertilizing the soil with the highly nutritious fertilizer (by-products of biogas production), it is possible for the farmers for the first time to realize optimum time and quantity for fertilizing, thereby benefiting both on quality and quantity while saving on the time factor. STATISTICSThere is vast potential for utilizing the environmentally safe burning of wastes for our daily purposes of electricity, water production using biogas technology. As long this potential is not utilized fully, any kWh c oming from atomic plants, can be considered as a crime against responsible sustainibility.According the calculations done by Prof. BOXBERGER of the Austrian University (Boku), based on the area covered by fermentation plants in Austria alone, biogas fermentation plants can produce energy that could substitute an equivalent of the use of 412.000.000 tons of oil for a similar quantity of energy. This could reduce 1.200.000 tons CO2 emission within just one nation. From this, one can very well imagine the numerous blessings that adoption of biogas technology could bring to our world at large! According to reports, agriculture is responsible for approximately 60% of man-made methane emission (greenhouse effect). This and many more can be reduced significantly by implementing most up to date biogas production technology. ATMA pyramidic fermentation plant with sedimentation device. SOME POSITIVE EFFECTS OF BIOGAS FERMENTATIONThe main positive effects of biogas-fermentation plants are:
Capable of producing 1.5 kWhel and 3 kWhcal of energy from 1 m3 biogas, through "Atma-Projects" an additional profit can be made by saving this fuel quantity which now has to be used, to spray the fermented liquids on the farmers fields. This results in up to 90% cost savings which is a major benefit to the farmers and other users of the technology. In this method of processing, soil microbes, which are responsible for soil texture improvement, are preserved and its population can grow and thus be the warranty for a healthy soil. The existence of sufficient microbes and other small creatures living within the soil are presupposition for optimum water filtering. A healthier soil is more capable of holding back rainwater which can also effectively diminish soil erosion. Erosion is a major problem in many countries around the world depleting the natural richness of the soil in addition to a number of other negative impacts. According to reports, within certain agricultural regions around the world, 15 tons per hectare of precious soil is washed away after heavy rains. Curing the soil is an inalienable necessity, if we do not want to find our fertile soil ending up in rivers. All seeds within the substrate and other unhealthy causes for diseases such as parasite eggs are most likely exterminated through the fermentation process, which means a great progress and advantage for human and veterinary medical aspects. Additionally, the need for herbicides and fungicides is minimized which again means a betterment towards soil- and water improvement. In this project natural hygenisation is heading for it's perfection because of the complete gasing out of the remaining substrate through long term heating to 70 degree Celsius of the solid substance. All intensive smelling substances of waste and manure will be eliminated by the fermentation process with this project. In other words, the complete gasing out of the matter is of decisive advantage. Odour irritation within this kind of processing is neither possible whilst processing nor by further use of precipitated waters. D. ADVANTAGES of "ATMA - FERMENTATION PLANT"PYRAMID shape of BIOGAS PLANT
SPECIAL FEATURES OF PYRAMID-FERMENTERPatenttext excerpt:The shape of the fermentation basin provides a fair relation between surface and volume by an easy to build form. The pyramidal form provides energetically positive results concerning the dryness of the biogas and the more tense molecular shape of the gas which results in higher combustion energy. The cosmic influence provided by the pyramidal shape works well for the micro bacterial fermentation process which results in a higher portion of Hydrogen within the gas which gives another positive result on the combustion energy. E. GENERAL INFORMATION on BIOGASBiological process:During storing time of "biogene energy source" already organic acids occur. This process intensifies after crunching. This is the first step of microbial decomposition. All other steps (except rest clearing in the open water basins, biotopes) perform within the fermenter without Oxygen in the form of mixed fermentation. At the end of decomposition stand methane bacteria's, which produce the desired biogas. All this process runs quite similar within the guts of humans and animals. Use of Biogas Biogas has a portion of Methane of approx. 60 -70 % (rest is mainly CO2) and will be dehumified, stored in the gasballoon and afterwards burned in e.g. Perkin's motors for energy production. The combustion heat is led in two separate circuits into hot water reservoirs, which provide the necessary processing temperature and if needed heat surrounding buildings. Around the world, pollution of the air, water and soil from municipal, industrial and agricultural operations continues to grow. Governments, industries, organisations and individuals are constantly searching for technologies that will allow for more efficient and cost-effective waste treatment and disposal. One technology that can successfully treat the organic fraction of wastes (biogenic wastes) is indeed anaerobic digestion through fermentation. When used in a fully-engineered system, fermentation of biogenic waste not only provides pollution prevention, but also allows for sustainable energy, water, fertilizer and nutrient recovery. Thus, this technology can convert a disposal problem into a profit center, and provides a realistic solution for environmental, social and economical problems for highly developed as well as for developing folks and nations.
