Wastewater and offensive odors have always been tough challenges in the development of a sustainable pig farming industry in Taiwan. The pollution prevention strategies, resource planning and technology guidance provided by ITRI to 577 pig farms resulted in over 74% of them meeting wastewater emission standards for effluent chemical oxygen demand (COD). Additionally, improvements in wastewater treatment efficiency enable pig farms to increase methane production. Through providing customized guidance for biogas generation sites, ITRI can help them gain increased economic benefits, with 45 ITRI pig farm guidance plan participants with a total installed power capacity of approximately 3.4 MW to date. Such biogas generating systems have now been invested in by facilities housing an estimated total of 2.5 million hogs, accounting for 45% of the pigs raised in Taiwan, and the methane can be used to reduce carbon emissions by an estimated 45,000 metric tons, which is equivalent to that produced by 160,000 motorcycles. This technology enables pig farm wastewater to be converted to environmentally friendly profit, thus transforming the corporate image of the industry as a whole.
