Abstract
The objective of this project is to study the existing methods of storage of waste and to develop these methods in order that the energy loss of waste-fuel and its negative environmental effects be minimized in a short and long period storage perspective. Naturally, the consequence of the study can be some development in the basic knowledge and techniques of waste-fuel storage. The main problem of waste-fuel storage is the danger of spontaneous ignition which may end up to a serious firing event. The spontaneous ignition is the result of physical, biological and chemical processes that produces heat and leads to a local instinctive combustion. Temperature and gas composition, i.e. O{sub 2}, CO{sub 2} and CH{sub 4}, were measured daily in different waste piles. During the first few months after storage, the temperature increased to 80-85 degrees C in the upper-part of waste heap and to 60-70 degrees C in the lower-part and it was found to be independent of waste composition. In the areas of higher temperature more oxygen was found to be present in all waste piles. The degradation processes accelerate at higher temperatures and above 80 degrees C. As a result, the temperature can be increased and

As a result, the temperature can be increased and be close to spontaneous ignition. The variations of O{sub 2} and CO{sub 2} inside the storage pile at the initial phase of storage are relatively large. However, after about 1.5 months, it approaches a steady state condition. The effective calorific value of the unsorted industrial waste has changed during storage time. However, the loss of energy was minimum in storage of waste woods and maximum in storage of offices and sale establishments waste. In the case of storage of household waste, pre-treatment of the waste has considerable effect on the loss of heat value. Sorting of the waste into wet and dry fractions before storage can result to an energy loss up to 25% for dry fraction after three years storage. 73 refs, 103 figs, 26 tabs}
