| dc.description.abstract | Energy is essential for the functioning of most of the industrialized world as well as developing and under-developed nations. Yet, at the same time, energy production and consumption causes degradation of the environment of the industrialized world and it seems that developing countries are also facing the similar kind of problem. Therefore, the managing of energy is always required everywhere in the world. Energy management is critical to our future economic prosperity and environmental well-being and it is one of the most critical issues for the future as so much of the world is dependent upon it. From the country-wise paper & paperboard production and consumption statistics, currently the annual total paper and paperboard production in Ethiopia is nearly 8,000 tons. The annual net consumption of paper in Ethiopia is 400,000 tons and the per capita consumption of paper in Ethiopia is 4 kg/year/person. However, the average per capita consumption of paper in the world is 57 kg/year/person. Consequently, the per capita consumption of paper in Ethiopia is among the lowest in the world today. By the way, the purpose of this thesis is not to focus on the amount of paper production and steam consumption. That is only on the amount of energy consumption and its cost. Moreover, it is also to focus on the ways how to minimize the cost of energy consumption and to increase the efficiencies of the energy consumption of the highly energy utilized devices. It is well-known that pulp and paper industry is highly energy intensive. Out of the total energy requirement of the paper and paperboard production in EPPSC, 81.69 % energy is used as process heat and 18.31 % as electric energy. Its energy requirement is estimated to increase further in the years to come. At present, its total energy consumption varies from 2,951.30 to 4,995.44 kWh/ton of paper. Notwithstanding, total energy consumption in paper manufacturing companies in developed countries varies from 1,450.00 to 1,650.00 kWh/ton of paper.

Therefore, the EPPSC consumes very high amount of energy compared with the international standards for energy consumption to produce paper. In addition to this, the boiler used for paper production in EPPSC is electric steam boiler which is not economically acceptable everywhere in the world and the highly energy utilized motors were bought before 50 years. | en_US |
