He has served as the consultant of various governments, research institutes, utilities, universities, and industries all over the world.


Speech Title: How to Make Livestock Manure-to-Energy Projects Successful?

Abstract: In the United States (U.S.), energy resource conversion of livestock manure is being actively pursued based on the program called AgSTAR: Biogas Recovery in the Agriculture Sector. The U.S. Environmental Protection Agency encourages biogas production in the agricultural sector using anaerobic digesters to achieve social, environmental and economic benefits through this program. However, technical and economic problems are still widespread. In general, anaerobic digesters for livestock manure are effectively operated by specializing in design, construction and operation, but economy is largely dependent on the collection and transport of manure, lack of organic waste for merging treatment, price fluctuations of electricity and gas companies, and regulations. The total methane gas production capacity in the U.S. is 7.9 million tons per year, which is 5% of U.S. total electricity production or 56% of transportation gas consumption. In this study, the livestock manure to energy projects in Wisconsin were evaluated and critical factors leading to success were identified. The economics of livestock manure biogas are declining due to the regulation of cheap electricity and gas supply companies. Currently in Wisconsin, the "Hub and Spoke" model is being developed to encourage livestock farmers to pump manure into a single large anaerobic digester. Energy recycling of livestock wastewater is the best way to manage manure. However, there are still many barriers. Most technical problems have been resolved through specialization and enlargement. Economics is the most important factor, and it is changing rapidly according to policy. In particular, if low energy costs continue, the government will need to support the economy in order to meet the economic feasibility. Finding the integrated use of nearby organic wastes and the use of energy generated by biogas is a shortcut to increase the economic efficiency.


Speaker IV

Prof. Laosheng Wu

University of California, Riverside, USA

Dr. Laosheng Wu is a Professor of Soil & Water Science, Agricultural Water Management Specialist, and Chair of the Department of Environmental Sciences, University of California at Riverside. He received Bachelor’s degree in Soil Science & Agrichemistry (1981) from Zhejiang University, China; Master’s degree in Soil Physics (1987) from Oregon State University; and Ph.D. degree in Soil Physics (1991) from the University of Minnesota.
Dr. Wu’s long-term goal is to promote safe application of lower quality water including recycled wastewater in agriculture and urban environment. His current research investigates the fate and transport of contaminants in soil and water receiving recycled wastewater application, evaluates the effect of salinity and other toxic elements from low quality irrigation water on crop growth, assesses soil quality response to recycled wastewater application, and develops optimal salinity leaching management practices for irrigated cropland.
Dr. Wu was elected as a Fellow of the American Society of Agronomy in 2009; a Fellow of the Soil Science Society of America in 2010; and a Fellow of the American Association for the Advancement of Science in 2010.
