A 26-story pig farm with 3700 pigs has been launched in Ezhou, China. The farm is equipped with a monitoring system for ventilation, temperature, and humidity, six elevators that can transport 240 pigs at a time, and is remotely controlled. The farm also plans to implement 'circular production' including high-temperature anaerobic fermentation to produce biogas from manure, which will be used to produce electricity, heat pigs, and provide hot water for animal washing.
