Turn pig manure into gold Swamp out the full cycle
Yunlin County, Taiwan's primary pig farming region, hosts over 1,200 farms housing approximately 1.56 million pigs. This industry generates substantial wastewater and greenhouse gases, posing environmental concerns. To address this, the local government promotes livestock manure and urine as fertilizers, reducing river pollutants by 16,925 tons of BOD and 21,701 tons of SS yearly. This initiative saves NT$49.98 million annually in chemical fertilizer costs, enhances soil quality, and boosts agricultural productivity, aligning with sustainable economic principles. The county advances livestock resource processing facilities, cutting annual livestock wastewater discharge by 494,000 tons, yielding 13,093 cubic meters of biogas for daily power generation, totaling 15,325 kWh and NT$39.2 million in electricity sales. Plans for centralized treatment plants in dense pig farming areas aim to address equipment inadequacies in small-scale farms and reduce carbon footprints. Anaerobic fermentation of livestock waste generates methane-rich biogas, utilized for electricity, curbing emissions and promoting a circular livestock-agriculture economy with net-zero emissions.
