IMPORTANCE OF ENERGY MANAGEMENT IN FOUNDRIES
Pollution prevention is preferable to reliance on end-

Cleaner production encompasses production processes and management procedures that entail less use of resources than conventional technologies and also generate less waste and smaller amounts of toxic or other harmful substances. It emphasizes the human and organizational dimensions of environmental management, including good plant operation to avoid deliberate or accidental discharges. Cleaner production and pollution prevention reduce the quantities of waste and eliminate some pollutants, but treatment and disposal of remaining wastes are also required. Improved energy efficiency reduces greenhouse gas emissions in two ways:
Energy efficiency measures for on-
Reductions in consumption of electricity lead to reductions in demand for electricity and, consequently, reductions in emissions from thermal electric power generating stations.
We have to remember that the key environmental issues included emissions to all environmental media; energy consumption has the first place but other environmental issues (such as consumption of raw materials, emission of noise, vibration, heat) and other factors can't be overlooked.
As it was shortly presented above, identifying energy management opportunities we can find the following broad categories:
Organizational changes -
Process changes -
Energy efficiency of melting and possibility of fuel substitution -
Electric power management -
Heat recovery -
The initial individual list of projects should be scrutinized from several viewpoints. All available information, such as good engineering practice, experience of others, supplier information, literature, consultants and possible synergies ought to be examined.
Monitoring energy performance helps managers identify wasteful areas of their department and lets them take responsibility for energy use. When monitoring shows that energy consumption is declining as improvements are being made, attention can be turned to the next area of concern. Of course the main tasks of our environmental efforts can't cover the maximizing of profitability. On fig. 3 the estimation of profit increase was shown in the situation when energy costs were reduced by 35%. We can easy find that the less current profit margin makes the bigger increasing of expected results.
In our present policy pollution prevention is preferable to reliance on end-

Globalne spojrzenie na problemy srodowiskowe pozwala stwierdzic, ze zmniejszenie emisji wynikajace ze zmniejszenia zuzycia energii ma miejsce w elektrowniach a nie odnosi sie do miejsc gdzie bezposrednio wprowadzane sa usprawnienia. Glownym celem zarzadzania energia jest okreslenie obszarow, w ktorych wystepuje duze zuzycie energii, gdzie dochodzi do duzych strat energii oraz wskazanie takich gdzie oszczednosci energii beda mozliwe do realizacji. Odlewnie nalezace do energochlonnych galezi przemyslu wymagaja kontroli zuzycia energii, aby mozna bylo okreslic gdzie, w jaki sposob energia jest wykorzystywana oraz jak efektywny jest system zarzadzania energia. Przedstawiono niektore aspekty zuzycia energii w odlewni oraz wskazano glowne obszary gdzie dochodzi do strat energii oraz mozliwosci wprowadzania usprawnien. Wskazano jak zarzadzanie energia wplywa na kierunki i efektywnosc zuzycia energii a procedury wynikajace z tego systemu umozliwiaja ograniczenie zapotrzebowania na energie.
