Especially organic waste, dumped in open places causes heavy environmental pollution to soil, groundwater and surface waters as the amount of the waste generated is growing very fast. However, energy from biomass may significantly contribute to the growing future demand for energy. Energy from biomass avoids the net increase of carbon dioxide in the atmosphere and would help to fulfil the obligations of the European Union to reduce carbon dioxide release. Biomass is the world's fourth largest energy source worldwide, following coal, oil and natural gas. Theoretically, biomass has the capacity to provide 100 % of the world's energy demand. In this study presents numerous processes of conversion of biomass for energy, i.e. thermochemical conversion (e.g. liquefaction) and biochemical conversion (e.g. digestion and fermentation) The conversion of orange peel (OP), hazelnut shell (HS), tea factory product wastes (TFPW), prickly pear cactus leaf (PPCL), peanut shell (PS) and market wastes (MW) into liquid and/or gaseous fuel by liquefaction process and the conversion of some potential organic waste matter [cow manure (CM), municipal organic solid waste components [market waste(MW) and treatment sludge (TS)] into to biogas and substance soluble in water have been investigated in the laboratory. Percentage and higher heating values of liquid products were founded between 14,3225,67 % and 30,50-48,10 MJ/kg in the result of liquefaction process respectively. On the other hand, from the results it was found that the maximum water solubility, amount of maximum biogas yield and maximum methane content of biogas were (83,2 % (by mass) 36,20 mL biogas/1g(dry) original cow manure and 52,40 % (by volume), (47,35 % (by mass), 33,34 mL biogas/1g original solid market wastes and 53,30 % (by volume) and (17,48 % (by mass), 2,64 mL biogas/1g original treatment sludge and 46,80% (by volume). According to results, it was found that petroleum-like liquid products can be obtained from these wastes by selecting suitable liquefaction conditions and these organic wastes were used for biogas production efficiently after converting into water soluble substances.eninfo:eu-repo/semantics/closedAccessBiomass wastesfosil fuelsbiogassubstance soluble in waterliquefactionConference Object413+N/AWOS:000276075800058N/A
