Publication Comparison of carbon footprints of different livestock operations(Parlar Scientific Publications (P S P), 2021-01-01) Kilic, Ilker; Ahmet, Begüm; Yaylı, Büşra; KILIÇ, İLKER; Ahmet, Begüm; YAYLI, BÜŞRA; Ziraat Fakültesi; Biyosistem Mühendisliği Bölümü; 0000-0002-0198-3550; 0000-0003-0087-6718; AAG-8340-2021; AAG-8511-2021; HKQ-2659-2023This study aims to estimate the carbon footprint resulting from the functional unit produced in a dairy cattle (100 head), a sheep (80 head), and a layer hen (12000 birds) enterprises operating in the Bursa region. In this study, 1 liter of milk in the dairy cattle farm, 1 kg of meat in the sheep farm and 1 kg of eggs in the hens' farm are considered as functional units. Within the scope of the study, Tier 1 and Tier 2 approaches were used to estimate methane gas emission both from enteric fermentation and manure management.The results obtained at the end of the study are 0.4215-1.0693 kg CO(2)e / L milk, 0.0912-0.1002 kg CO(2)e / kg meat, 0.3834 kg CO(2)e / kg egg for Tier 1 and Tier 2 approaches, respectively. Since the data containing the Tier 2 approach for the poultry operation is not available, the calculation could not be made. In line with the results, processes such as adding quality and high-energy foods to feed ration, better planning of manure operating systems, and composting are recommended for reducing enteric fermentation.Publication Air quality measurements in four sheep barns part ii: Pollutant gas emissions(Springer, 2021-01-04) Kılıç, İlker; Şimşek, Ercan; Yaşlıoğlu, Erkan; Heber, Albert; Uğuz, Seyit; KILIÇ, İLKER; ŞİMŞEK, ERCAN; YASLIOĞLU, ERKAN; UĞUZ, SEYİT; 0000-0002-3865-7863; 0000-0002-3994-8099; 0000-0003-0087-6718; ABH-7275-2020; AAH-3553-2021; AAG-8511-2021; ABE-6643-2020Pollutant gas emissions from animal barns affect indoor air quality, the health and well-being of farmers, and the surrounding environment. This study was carried out in four sheep barns (SB) in Bursa, an important region for animal husbandry operations. Concentrations of NH3, CO2, H2S, and CH4 were measured in four sheep barns by monitoring throughout 24 h in 1 year. Pollutant gas emissions from barns were also calculated and modeled. The average pollutant gas emissions obtained in this study were 5 kg day(-1) barn(-1) for NH3, and 18 kg day(-1) barn(-1) for CH4. The average NH3 and CH4 emissions from each barn were 2.1 and 2.7 kg day(-1) barn(-1) for SB1; 9.4 and 12.9 kg day(-1) barn(-1) for SB2; 4.0 and 3.6 kg day(-1) barn(-1) for SB3; and 4.5 21 kg day(-1) barn(-1) for SB4, respectively. There are statistically significant differences between daytime and nighttime for pollutant gas emissions. Pollutant gas emissions in the monitored barns are generally higher in summer than in other seasons. Models for estimating NH3, and CH4 emissions were developed using measured temperature and relative humidity values in the barns. These models can only be used in the Bursa region. The results of this study were compared with other studies under similar conditions in the literature.Publication Ammonia and carbon dioxide concentrations in a sheep barn(Kahramanmaras Sutcu Imam Univ, 2017-01-01) YASLIOĞLU, ERKAN; ŞİMŞEK, ERCAN; KILIÇ, İLKER; Onuk, Apti; Ziraat Fakültesi; Biyosistem Mühendisliği Bölümü; 0000-0002-3865-7863; AAH-3553-2021; ABE-6643-2020; AAG-8511-2021Indoor air quality in animal barns directly affect to animal productivity. Measuring the pollutants in animal barns proves the negative effects of gases on health of animals and workers. Most studies in this context focused on some pollutant gases such as ammonia, carbon dioxide, methane and hydrogen sulfide in dairy barn and poultry houses. Less attention in studies in scientific literature was paid to sheep barns which may have more important portion than other animals for the animal production sector of some countries. This paper revealed the concentrations of ammonia (NH3) and carbon dioxide (CO2) in naturally ventilated sheep barn in Bursa region, western Turkey. Also indoor environmental conditions such as temperature and relative humidity were measured simultaneously with pollutant gas concentrations. Regression and variance analyzes were applied to assess data collected in sheep barn whole over the study period. The average NH3 concentration during the study was 15 ppm for exhaust and 0.77 ppm for ambient, CO2 concentration was 1022 ppm for exhaust and 457 ppm for ambient. There was significant difference among measurement days for exhaust NH3 and CO2 concentrations (P< 0.001). The lowest NH3 concentration was 8 ppm while lowest CO2 concentration was 277 ppm, and the highest concentrations were 38 ppm for NH3 and 1700 ppm for CO2. Also minimum, maximum, average values for indoor temperature were 16.06 degrees C, 26.53 degrees C, 20.69 degrees C, respectively, while minimum 43.42%, maximum 89.6%, average 71.23% values for relative humidity were obtained. According to regression analyze results, the exhaust NH3 concentration related statistically significant with air velocity. The standardized coefficients suggest that indoor temperature and relative humidity sustained the greater effects on CO2 concentrations (P< 0.001).Publication Modelling of pollutant gas dispersion from dairy cattle barns(Gazi Univ, Fac Engineering Architecture, 2019-01-01) Demirarslan, Onur Kazim; Kılıç, Ilker; KILIÇ, İLKER; Mühendislik Fakültesi; Biyosistem Mühendisliği Bölümü; AAG-8511-2021The increased number of modern livestock farming increase pollutant gas and particulate matter emissions and expanding of residential area against rural area cause to be more sensitive to these gas and particulate matter emissions from animal operations. In this study, pollutant gas dispersions from three dairy cattle barns operated in Bursa region were modelled using hourly outdoor environmental and topographic conditions. To develop dispersion models and describe dispersion problem as a quantity, pollutant gas emissions from dairy cattle operations and CALPUFF VIEW 5.8 modelling software were used. It was determined that estimated pollutant gas concentrations in five receptor points (A-E) in surrounding environment were significant levels. Furthermore pollutant gas emissions from dairy cattle barns can reach a remarkable values in an area with 2000 in diameter in surrounding environment.Publication Assessment of environmental impacts of broiler farms using different indicators(Springer, 2022-01-21) Yaylı, Büşra; Kılıç, İlker; YAYLI, BÜŞRA; KILIÇ, İLKER; Ziraat Fakültesi; Biyosistem Mühendisliği Bölümü; 0000-0002-0198-3550; AAG-8340-2021; AAG-8511-2021This study aims to evaluate environmental impacts within farm boundaries in broiler production systems in Turkey. There have been calculated on three-stage assessing environmental impacts: carbon footprint and water footprint. The objectives were evaluated by taking into account 1 kg of chicken meat of the functional unit. Using three different methods (real-time gas concentration, Tier 1 approach, and life cycle assessment) the carbon footprint was evaluated. We obtained an average of 2.9 kg CO2/functional unit for the carbon footprint using measured gas concentration data. Accordingly, with the Tier 1 method developed by Intergovernmental Panel on Climate Change, it has been shown that 5.1 kg CO2 equivalent carbon footprint per functional unit occurs in the broiler farms. Based on the life cycle assessment, the emissions were 3 kg CO2 equivalent per functional unit. The second stage of the study was the determination of water footprints in broiler production systems. The water footprint of farms was evaluated with SimaPro 8.2 software. According to the results, 0.003 m(3) water/functional unit was obtained by considering the drinking water and using water amount in the production.
