Öğe A holistic approach to soil contamination and sustainable phytoremediation with energy crops in the Aegean Region of Turkey(Elsevier Ltd, 2021) Baştabak B.; Gödekmerdan E.; Koçar G.The objective of this current review article is to evaluate the current knowledge of the contaminated soil in the study area based on reports and the results of previous experimental studies in the literature and to discuss the feasibility of phytoremediation with biofuel production using energy crops. The results indicated that the soil contamination was related mainly to the thermal power plant and mining activities in Kütahya, high industrial activity in İzmir, heavy metal and radioactive pollution in Manisa and Muğla. Moreover, the sources of the contamination are geothermal resources and transportation in Aydın and Denizli, respectively. However, soil pollution in Afyonkarahisar and Uşak provinces has not been discussed due to a lack of detailed reports and data in the literature. Besides, energy crops such as Zea mays, Ricinus communis, and Gossypium hirsitum were identified as appropriate candidates for İzmir, Denizli, Manisa, and Aydın due to being resistant to the arid climate. In Muğla province, Eucalyptus grandis and Eucalyptus bicostata can be cultivated because of having adaptation to moderate climatic conditions. Ricinus communis and Helianthus annuus were determined to be very suitable energy crops for the phytoremediation of many heavy metals in Kütahya. The review promotes the development of economic, environmental, and social benefits to regain the contaminated areas through phytoremediation. The findings of the study are important for creating sustainable solutions for remediation of polluted soils in Turkey, as well as for shedding light on the process of establishing appropriate policies to make soils contaminated suitable for agriculture. © 2021 Elsevier LtdÖğe Oil Crops for Energy(Elsevier, 2017) Koçar G.Oil crops have always been an important segment in the world's agriculture. Vegetable oils have been used in human and animal nutrition and to a lesser extent for nonedible applications. Recently, however, due to high energy prices and a greater awareness of the environmental consequences of fossil fuels, oil crops can be refined to transport biofuels such as biodiesel esters. Biodiesel has an increasing importance in the world energy matrix, and the demand of biodiesel is expected to increase significantly in the near future. In this article, the potential of using oil crops for biofuel production based on conversion processes was examined. © 2017 Elsevier Inc. All rights reserved.Öğe Power production from agricultural wastes and implementations(Czech University of Life Sciences Prague, 2010) Yaldiz O.; Kaya D.; Saraç H.I.; EkIncI K.; Koçar G.; Küçükkara B.The management of agricultural wastes in distribution of scarce resources is an important factor in the economics. The task of the management of material flow becomes relevant for agriculture with the beginnings of the industrial production. Utilization of agricultural wastes for energy production means an income for agricultural sector. Agricultural sector is the largest business sector since the past in Turkey. Depending on the country's development reduces the share of this sector but maintains of total production and employment. In Turkey, the agricultural sector constitutes 90% of field crops and livestock (Kaya vd,2006) [1] . This study was constructed by considering the environmental, economical and social benefits and focus of this study is the production biogas from agricultural and animal wastes and utilization of obtained gases in integrated energy conversion technologies. The tasks in these study includes: review biogas and energy production technologies, system simulations and DSS modeling, design and development of two lab-scale (one for animal waste and other for agricultural waste) and one pilot scale (250 kW capacity) integrated biogas plant, integration of the pilot plant with energy conversion systems, experimental study, feasibility study including techno-economical analysis of the whole system, life cycle analysis and dissemination of the project results. © 2010 Czech University of Life Sciences Prague.
