Continuous growth in global energy demand, depletion of fossil resources and climate change concerns associated with fossil fuel combustion have increased the motivation on utilization of renewable energy sources. Utilization of renewable sources is vital in Turkey as the country highly depends on imported energy. Biogas is a renewable energy resource produced from decomposing organic waste under anaerobic conditions. Production of biogas from organic wastes such as animal manure is advantageous to contribute renewable energy production and waste management strategies for health and environmental protection. In this study, the animal manure based biogas energy potential of the Mediterranean Region of Turkey is determined. The region is composed of eight provinces including Antalya,
In this study sustainable valorization of cattle manure, recycled polyester, and their blend (1:1 wt.%) were examined by the thermogravimetric analysis (TGA) method. Pyrolysis tests were performed at 10, 30, and 50 °C/min heating rate from room temperature to 1000 °C under a nitrogen environment with a flow of 100 cm3/min. Kinetics of decomposition were analyzed by using Flynn–Wall–Ozawa (FWO) method. Based on activation energies and conversion points, a single region was established for recycled polyester while three regions of pyrolysis were obtained for cattle manure and their blend. Comparison between experimental and theoretical profiles indicated synergistic interactions during co-pyrolysis in the high temperature region. The apparent activation energies calculated by FWO method for cattle manure, recycled polyester. and their blend were 194.62, 254.22 and 227.21 kJ/mol, respectively. Kinetics and thermodynamic parameters, including E, ΔH, ΔG, and ΔS, have shown that cattle manure and recycled polyester blend is a remarkable feedstock for bioenergy.
Sustainable development depends on the availability of energy resources and their impact on environment. Biogas is a carbon neutral renewable energy option and one of the leading solutions to the climate change combat. As Turkey is an energy importer country, using indigenous energy sources is vital to meet future energy demand. Agricultural activities and livestock potential have high contribution to economy in Turkey. Biogas production from organic wastes such as livestock manure in this context, gain more importance to contribute both renewable energy production and waste management strategies. Livestock farming has important economic value in Burdur. In this regard, the animal manure based biogas potential, energy value, electricity and organic fertilizer generation capacity of Burdur Province were determined in this study. The results revealed that Burdur has annually 1.45 million tons of available animal manure potential to be used for biogas production of 27.1 million m 3 /year. This potential corresponds to 135.4 GWh annual energy generation that could be converted to heat and electricity. Considerable amount of the biogas production capacity has accumulated in the Center and, Bucak, Yeşilova, Gölhisar and Karamanlı districts of Burdur. In addition, about 50776 tons/year of organic fertilizer can be produced as the residual of the biogas plants.
Continuous demand for global power generation has increased the attention on renewable energy sources. Biogas is one of the viable options for conversion of organic waste materials into green power and valuable products. In this study, the impact of biogas production from agricultural residues (wheat straw, barley straw, corn stover, cotton residue, olive residue, banana peel, sugarcane bagasse, tomato residue) and municipal solid waste (MSW) on reduction of greenhouse gas (GHG) emissions in Mediterranean Region of Turkey
