This aims to prevent direct entry of livestock waste into streams, thereby reducing environmental pollution. Agricultural enterprises started disposing of manure jointly at four large-scale plants equipped with specialized technologies and facilities in 2007 with the intention to build stable infrastructure for manure processing and to efficiently manage livestock waste in areas with high-density livestock farms, including pigs. These facilities started to produce solid or liquefied fertilisers, partly motivated by the Korean government’s decision to ban the ocean-dumping of livestock excretion in 2012.
