Project Activity

We invite you to join us for an informative session on "Integrated Approach to Recycling Nutrients from Organic Wastes to Agriculture via Methane Fermentation," presented by Prof. Hidenari Yasui from The University of Kitakyushu, Japan.

In response to the recent surge in global fertilizer prices, the Japanese government has reinforced its commitment to recycling nutrients from organic waste for agricultural purposes. Municipal wastewater treatment plants are now being tasked with producing fertilizers in addition to treating pollutants. During this session, Prof. Yasui will introduce an innovative approach that optimizes both nutrient production and waste treatment through methane fermentation. The talk will also highlight field test results that demonstrate the effectiveness of a new organic fertilizer, derived from digestate, in enhancing vegetable cultivation.

Prof. Hidenari Yasui is a distinguished expert in environmental technologies, with a focus on biological wastewater treatment systems. With over two decades of experience in engineering and more than 150 patents to his name, Prof. Yasui has been instrumental in advancing cutting-edge technologies across Japan and Asia. Since the 2010s, he has led research projects in Thailand and Vietnam, aimed at recovering valuable materials through biological treatments. His scientific approach, which emphasizes mathematical modeling of experimental results, seeks to optimize complex biological reactions that are not fully understood through experimentation alone.
