In this study, the combustion of olive byproducts was investigated using the TG-FTIR technique. Different types of olive biomass were considered: twigs, leaves, olive-mill waste from the two-phase decanting method, and wastewater from the three-phase system. The reaction regions, ignition, and burnout temperatures at different heating rates were determined using TG/DTG analysis and the thermogravimetry results. Comprehensive combustion, ignition, burnout, and flammability indexes were also calculated. The highest combustion index values were obtained for waste from the three-phase system, followed by the two-phase decanting method, then with leaves and small twigs. The order of the index values indicated that the sample from the three-phase process ignited more quickly and yielded faster. The changes in activation energy calculated using different model-free isoconversional methods—Friedman, Ozawa–Flynn–Wall, and Kissinger–Akahira–Sunose—fell within the range of 130–140 kJ/kmol. FTIR analyses presented differences in the exhaust gas composition for specific combustion temperature ranges.

This study was conducted to determine the effects of various water deficits on the yield, water use efficiency, and fiber quality of cotton in the semiarid region of Turkey during 2017 and 2018. In the study, cotton was subjected to a number of irrigation treatments based on soil water depletion replenishment. In the T100 (control) treatment, irrigation was performed when ~ 50% of the available soil moisture was consumed in the root zone at 1.2 m depth during irrigation periods. Cotton undergoing the control treatment received full irrigation (100% soil water). Treatments T75, T50, T25, and T00 were irrigated with 75%, 50%, 25%, and 0% of the water used in the control treatment (T100) on the same day, respectively. According to the results, the average seasonal water use and seed cotton yield ranged from 305 to 780 mm and from 2913 to 5953 kg/ha, respectively. The presence of a water deficit significantly affected the crop yield. The highest average cotton yield was obtained with the full irrigation treatment (T100). The average water use efficiency (WUE) varied from 0.76 to 1.06 kg/m3 in both years. Fiber quality was influenced by the drip irrigation level in both years. The results revealed that the full irrigation treatment (T100) could be used in semiarid climatic conditions when there is no water shortage. On the other hand, the results also demonstrated that drip irrigation of cotton with the 75% irrigation regime (T75) had significant benefits in terms of saving irrigation water and achieving a high WUE, indicating that there is a definite advantage of implementing deficit irrigation under limited water supply conditions.

In this paper, the dairy cattle waste management systems on farms in Aydın region in Turkey were investigated. Number of farms and livestock herd size, type of barn, type of machinery and farm labour force were studied. The collection, management and storage systems of manure produced in dairy cattle farms were taken into consideration. Additionally, biogas amount, which is produced from animal waste, was calculated for all districts of Aydın by using the number of livestock animals and various criteria such as the rate of dry matter. Results show that the typical and representative farm in the Aydın region is facility with a total head over 100 heads. 89.6% of the farms have heads in the range of 100 to 200. The amount of biogas that can be produced from all manure collected in Aydın region in the biogas plants is approximately 160,438 m3/day (based on 0.5 m3/day biogas per cattle), which would produce around 100 GWh/year that can be used for own needs of farms owners.

This paper concerns the process of production and properties of pellets based on biomass wastes. Co-pelletization was performed for sewage sludge from municipal wastewater treatment plant and other biomass material such as animal and olive wastes. The aim of the present study was to identify the key factors affecting on the sewage sludge and agricultural residues co-pelletization processes conditions. The impact of raw material type, pellet length, moisture content and particle size on the physical properties was investigated. The technic and technological aspects of co-pelletization were discussed in detail. The physical parameters of pellets, i.e.: drop strength, absorbability and water resistance were determined. Among others, also energy parameters: low and high heat value, content of ash and volatiles were presented. Results showed the range of raw materials moisture, which is necessary to obtain good quality biofuels and also ratio of sewage sludge in pelletizing materials. The analysis of the energetic properties has indicated that the pellet generated on the basis of the sewage sludge and another biomass materials can be applied in the processes of co-combustion with coal. Those biofuels are characterised with properties making them suitable for use in thermal processes and enabling their transport and storage.

Geothermal energy is classified as a clean and sustainable energy source, like all industrial activities, geothermal energy power plants (GEPP) technology has also some positive and negative effects on the environment. In this paper are presented by attent not only on environmental impacts of GEPP onto Büyük Menderes River and fresh water sources, which ere used for irrigation of agricultural fields from tousands of years in basin, but also on water quality contents like heavy metals and gases emition due to drilling and electricity producing technology of GEPP's. Aydın province is located in the southwestern part of the region and its city center has around 300000 population. The high geothermal potential of this region became from geographical location, which is held on active tectonic Alpine-Himalaya Orogen belt with active volcanoes and young faults. Since 1980's to 2016 there is about 70.97% (662.75 MW) of installed capacity by according to the Mineral Research and Exploration General Directorate, there are totally 290 well licensed (540 explore licenses and 76 business licenses), and 31 geothermal powerplants purposely installed. Topic is important because of number of GEPP increased rapidly after 2012 to now a days to 36 in whole basin.
