Prof. Dr. Duong Nguyen Khang received a Ph.D. degree in Animal Nutrition and Management at the Swedish University of Agricultural Sciences in 2004. Five years after, he got the Associate Professor title. He also got the Full Professor title in 2019. At present, he is a member of the Professional Associations of Vietnamese Biogas, a member of academic training at Nong Lam University. He has published more than 80 national and international articles relating to animal methane emissions and biodigester. He found nutritional solutions balancing in emissions and utilization of carbon dioxide as well as reduction of methane: meat production ratios in cattle production. In Vietnam, he developed the humid tropical areas of a sustainable system of integrated livestock, black soldier fly (for animal/bird manure treating, crop/food processing wastes treating…), and fuel production based on fractionation of high biomass crops, forage trees and water plants with emphasis on ruminant and recycling of wastes which is environmentally friendly by using the black soldier fly. It is based on agroecological principles of organic-based inputs and biological control of pests and diseases, the feeding systems for ruminants in mountain areas using sugar cane, leaves from trees and water plants have been introduced and developed to poor farmers. Besides that he also set up the low-cost plastic biodigester and improvements to the technology, over 500,000 units installed and paid for by farmers. It reduced methane production from animal wastes.
Prof. Dr. Duong Nguyen Khang's research interests are Animal production/reproduction/nutrition. Feeding systems for ruminants. Nutritional solutions balance emissions and utilization of carbon dioxide as well as reduction of methane. A sustainable system of integrated livestock, black soldier fly for animal/bird manure treating, crop/food processing wastes treating. Recycling of wastes. Biodigester. It reduced methane production from animal wastes.
