Kırşehir ilinin örtü altı domates yetiştiriciliğinde bitkisel artık kaynaklı enerji potansiyelinin mekânsal olarak değerlendirilmesi

Abstract

In this study, it is aimed to determine the amount of biomass waste, energy potential and usability of greenhouse tomato production in Kırşehir and to evaluate spatial distribution of the findings. Methods and Results: In the districts of the Kırşehir, the annual dry waste amounts from tomato plants were calculated as 144525 kg, 96350 kg, 22550 kg and 263425 kg in total, respectively, in Central, Çiçekdağı and Kaman towns. The thermal energy potential that is obtained in these areas depending on the amount of wastes was calculated as 4046208 MJ in total. Considering the distribution of this value by districts, it was calculated as 2219904 MJ in the Central, 1479936 MJ in Çiçekdağı and 346368 MJ in the Kaman. The production area, production amount, waste and the energy potential values that can be obtained from the wastes were become an updateable database using Geomedia Professional 6.0 geographic information system software which allows spatial queries than maps were produced and evaluated. The corresponding amounts of other sources to the energy potential that can be obtained from tomato wastes is 468311.5 kg for wood, 301771.4 kg for domestic lignite coal, 212426.3 kg for imported Siberian coal, 127028.4 kg for fuel oil, 126021.5 m 3 for natural gas and 1136437.0 kWh for electricity. Considering the CO2 emissions emitted by the other fuels that can be used in equal potential energy value of the biomass wastes that can be obtained from the tomato plant grown under cover in Kırşehir, with coal and natural gas, the possible annual CO2 emission to the atmosphere is 337184.3 kg and 213550.0 kg respectively and this amount can be decreased to 28098.7 kg with the use of the biomass. Conclusions: Considering the results of the study, it was determined that tomato wastes constitute an important energy potential and are also very important in terms of reducing CO2 emitted into the atmosphere compared to many fossil fuels. Significance and Impact of the Study:The results show that it is important to utilize the thermal energy potential of tomato wastes to reduce dependency of energy import. Utilization of bioenergy potential of undercover tomato wastes is also important when considering aspects such as reducing the environmental impact of these wastes, providing an alternative to fossil fuels and reducing the CO2 emissions.
