“…Usually, high NH 3 emissions occurred in the compost, and a large ratio of unaccounted N loss in this study existed in the form of NH 3 . Meanwhile, high N 2 O emissions indicated the occurrence of nitrification and denitrification in I60 treatment; thus, end products, such as N 2 would occupy some parts of unaccounted N [28]. Moral et al [66] reported that N 2 -N emission was 5 times higher than NH 3 -N emission during cattle farmyard manure storage.…”

“…Gas sampling and analysis were performed using a modified gas monitoring system from Wang et al [28]. A photoacoustic multigas analyzer (Innova 1412i, LumaSense Technologies, Ballerup, Denmark), a NO analyzer (model 42i, ThermoFisher Scientific Inc., Waltham, MA, USA), a H 2 S–SO 2 analyzer (model 450i, ThermoFisher Scientific Inc., Waltham, MA, USA) along with a multichannel sampler (fabricated at the Institute of Environment and Sustainable Development in Agriculture, Chinese Academy of Agricultural Sciences, Beijing, China) were used to sample and analyze air samples from nine composting reactor air sample outlets and one fresh air supply.…”

This study aimed to investigate the characteristics of gaseous emission (methane—CH4, carbon dioxide—CO2, nitrous oxide—N2O, nitric oxide—NO, hydrogen sulfide—H2S and sulfur dioxide—SO2) and the conservation of carbon (C), nitrogen (N), and sulfur (S) during cattle manure composting under different aeration strategies. Three aeration strategies were set as C60, C100, and I60, representing the different combinations of aeration method (continuous—C or intermittent—I) and aeration rate (60 or 100 L·min−1·m−3). Results showed that C, N, S mass was reduced by 48.8–53.1%, 29.8–35.9% and 19.6–21.9%, respectively, after the composing process. Among the three strategies, the intermittent aeration treatment I60 obtained the highest N2O emissions, resulting in the highest N loss and greenhouse gas (GHG) emissions when the GHG emissions from power consumption were not considered. Within two continuous aeration treatments, lower aeration rates in C60 caused lower CO2, N2O, NO, and SO2 emissions but higher CH4 emissions than those from C100. Meanwhile, C and N losses were also lowest in the C60 treatment. H2S emission was not detected because of the more alkaline pH of the compost material. Thus, C60 can be recommended for cattle manure composting because of its nutrient conservation and mitigation of major gas and GHG emissions.

Energetski potencijal stajnjaka povezuje se najčešće sa produkcijom biogasa. Postavljanje razmenjivača toplote u prostor za kompostiranje daje mogućnost akumulacije toplote oslobođene u procesu razlaganja organske materije. Hlađenje stajnjaka pri redukciji gubitaka nutritivne vrednosti rezultira produkcijom adekvatne toplote. Koeficijent grejanja predstavlja odnos između količine toplotne energije dobijene toplotnom pumpom i utrošenog rada za njenu operativnost. Maksimalna vrednost koeficijenta grejanja realizovana je pri t i = 35° C i t p = 40° C: ε G = 6,6, dok je minimalna bila ε G = 2,5 pri t i = 15° C i t p = 50° C. Akumlisana voda, u zavisnosti od potreba, može biti upotrebljena kao samostalni izvor toplote za dogrevanje: objekata za tov pilića, prasilišta, sanitarnih prostorija itd.
