In the newly developed low-emissions pig pen system, pigs are kept in an outdoor climate stall with internal, encapsulated comfort area. All aspects of animal health and welfare are taken into consideration. Neither dung nor liquid manure arise at the end. Faeces and urine are collected separately and further treated to produce fertilizer products or biogas substrate. Ammonia emissions are reduced by 70% and methane emissions by 90%. The system is registered for patent.
