By Chen Wen-ching 陳文卿Among Taiwan’s state-run enterprises, Taiwan Sugar Corp (Taisugar) has been more agile in its corporate transformation and has the most diverse business operation. Biogas residues and slurry resulting from the anaerobic fermentation of pig manure and urine for biogas production can be turned into organic fertilizers and reused for the land. Biogas residues and slurry created from anaerobic fermentation contain an abundance of organic matter that is ideal as agricultural fertilizer. Taisugar does not have to worry about this problem, because it has both pig farms and forest land. Pingtung County is a major pig farming county, and pollution caused by wastewater discharged by pig farms constitutes an environmental problem that has been bothering government agencies.
