Abstract:

Animal farms are have to be controlled regarding to environmental issues beacuse of their waste’s effects. Dispersion of harmful gases and odour is some most important effect of animal waste. Decomposition of animal waste may cause dispersion of harmful gases such as ammonia, methane, carbon dioxide, hydrogen sulfide etc. and odours. Harmful gases and odours impact on human and animal welfare negatively. Biofiltration is a technique used to prevent the dispersion of harmful gases and odour on animal farms. Especially some animal production types such as swine and poultry farms may cause great problem in terms of harmful gases and odour, so biofiltration has been seen as an effective method treating polluted air in these farms. The process of biofiltration is conducted based on biological degradation of pollutants. The bed materials such as litter, mulch and woodchips etc. are used in biofiltration to ensure microbiological environment. In this study, it was purposed to give information about the biofiltration, its basic principles and usage on animal farms based on conducted researches.

Abstract:

The purpose of this study was to determine the biogas production capacity from animal wastes in Marmara region of Turkey for the years 2005–2014. The wastes from the cattle and hen in the region were considered the resource for biogas production taking the number of animals and the collectability of the wastes into the account. Three scenarios were evaluated to estimate the biogas capacity by assuming that 100% (theoretical potential), 50%, and 25% of the total animal waste could be used for biogas production in the region. For theoretical biogas production from cattle wastes, the greatest potential in the year 2014 was calculated for Balıkesir province with 145.53 Mm3, followed by Çanakkale, Bursa, Sakarya, and other seven provinces. Balıkesir had the highest biogas potential in 2014 from the poultry waste, too, followed by Sakarya, Kocaeli, Bursa, and other seven provinces. Biogas potential (100%) of Marmara region increased by 15% from 2005 to 2014 with 1,242.17 Mm3 in 2014. The heat and electrical energy equivalents of the biogas were found to be 7,453.02 GWh and 2,608.56 GWhe, respectively. In the other two scenarios, depending on the utilization rate of theoretical biogas potential: biogas amount, heat and electric power values were determined proportionally.
