Pig farming in mechanically ventilated barns requires much electricity for ventilation or exhaust air purification. Furthermore, thermal energy is needed to fulfill the animals’ temperature requirements, especially piglet rearing. Electrical and input leads CO2 emissions operating costs. Up 90% of heat losses are due exhausted air. Heat exchangers can recover from warm transfer it cold fresh This study aimed investigate consumption, efficiency, emissions, costs when using a German rearing...
Abstract Background Silage emits climate- and environment-relevant gases during anaerobic fermentation aerobic feed-out periods. This trial should determine the unknown CO 2 , methane, nitrous oxide, ethanol ethyl acetate emissions of constant maize silage over both The results will be published in two consecutive articles (Part A: period; Part B: storage period). Methods Three treatments were observed ( n = 4): untreated control (CON) was compared to chemical additive treatment (CHE; 0.5 g...
In this study, biological exhaust air treatment was combined with a recuperative heat exchanger in one process stage. The aim of plant development and testing is not only to reduce ammonia from the pig houses but also recover thermal energy at same time. This intended offset high operating costs savings heating cold seasons use more efficiently. system tested for first time under practical conditions fattening house southern Germany. Three different assembly situations were examined 13 days...
