The need for additional energy sources is growing from day to day. Fossil fuels are not renewable energy sources, so alternative solutions need to be considered. One such solution is the use of waste as a source of energy, where waste ceases to be the waste and becomes material. In recent years, research has shown positive effects of using agricultural residues for the purpose of energy production. Biomass that emerges after the cultivation of the pomegranate (Punica granatum L.), which is peel and pomegranate seeds, make almost up to 45-60 % of the total weight of the fruit, which due to its high energy value organic compounds, represent a potential source of energy. Therefore, it is necessary to investigate the energy properties of the above-mentioned residues, to investigate their applicability for use as feedstock for energy production. This paper deals with the preparation of samples for the physiochemical and fuel analysis of the peel and pomegranate seeds of two different varieties of pomegranate raised in Croatia (Glavaš and Dividiš). The analyses were carried out to determine the energy utilization and we used: ash analysis, coke contents, fixed carbon content, volatile and combustible substances, cellulose and hemicellulose contents as well as the upper energy value. One of the key problems in the world is the increased energy consumption. Unsustainable sources, predominantly oil and gas, always prevail in the energy consumption. But this does not change the fact that these are non-renewable energy sources which has remained less and less in the world, since they are irreversibly consumed day by day and leaving behind harmful effects on the environment as well as on human health. Alternatives to this are renewable energy sources, including biomass. One of the countless possibilities offered by biomass is to use biomass as feedstock for the production of heat and electricity, or energy by direct combustion. The aim of this study was to determine the possibility of using biomass, namely pomegranate peel and seeds that remain after processing, as well as to determine their potential as an energy source for production of energy via direct combustion.
