The 4th International Conference on Valorization of Agricultural Residues: Solutions Towards Climate-Smart Agriculture in Southeast Asia

The 4th International Conference on Valorization of Agricultural Residues: Solutions Towards Climate-Smart Agriculture in Southeast Asia
 The 4th International Conference on Valorization of Agricultural Residues: Solutions Towards Climate-Smart Agriculture in Southeast Asia

The 4th international conference on "Valorization of Agricultural Residues Towards Climate-Smart Agriculture in South-East Asia,"  was successfully held at Hanoi University of Science and Technology (HUST) on September 19, 2024. The event was co-organized by the Technical University of Berlin (TUB). The conference provided a platform for Vietnamese and international experts to exchange knowledge, aiming to develop efficient and sustainable organic waste management methods tailored to local contexts.
The conference focused on three main themes: Biomass Resources and Bioenergy; Sustainable Technologies; and Environmental Impact Assessment and Management.
Assoc. Prof. Dr. Huynh Dang Chinh, Vice President of HUST opening remarks
Agricultural waste, primarily composed of starch and lignocellulose from plants and protein-rich components, is often discarded into the environment or directly burned, wasting valuable natural resources and causing environmental harm. Effective agricultural waste management needs to be adapted to geographic, climatic, cultural, and technical requirements. A climate-smart agricultural approach enables agricultural systems to adapt efficiently to climate change while also effectively managing waste. Biogas filtration technology, which converts organic waste into energy and circulate sulfur, is a prominent solution that not only reduces emissions but also promotes sustainable resource use.
This conference was part of the Vietnam-Germany S-IRCLE research project (Circular Biogas Technology – Smart Filtering Systems for H₂S Removal and Sulfur Recycling). The project aims to develop an automated filtration system to remove H₂S in small-scale biogas plants and recycle sulfur from the filtering materials into fertilizers. Additionally, the project evaluates the environmental impact of this new biogas filtration system compared to existing methods.
Assoc. Prof. Dr. Huynh Dang Chinh and Prof. Dr. Nguyen Xuan Thinh - Dortmund University of Technology
The conference was attended by various experts, scientists, and Ph.D candidates  come from Technical University of Berlin, Technical University of Dortmund, Herbst Umwelttechnik GmbH company (Germany), University of Hiroshima, Hanoi University of Science and Technology, University of Da Nang, University of Thai Nguyen, Vietnam Livestock Association,  Egreen JSC. (Vietnam).
Opening the conference, Assoc. Prof. Dr. Huynh Dang Chinh emphasized the crucial role of agriculture in Vietnam’s economic growth, accounting for 12% of the GDP in 2022. He also highlighted the goal of reducing greenhouse gas emissions in agriculture and affirmed that utilizing agricultural residues is a promising solution, though it still faces technological and economic challenges. HUST, with its leading academic staff, has made significant contributions to the government’s science, technology, and innovation policies. In 2022, the university was upgraded to a multidisciplinary research institution. The newly established School of Chemical and Life Sciences focuses on fields like food technology, biotechnology, and sustainable development. His speech concluded with a word of gratitude to the co-organizers and stakeholders for their contributions to the success of the conference.
 
Assoc. Prof. Dr. Nguyen Thi Anh Tuyet, Vice Dean of the School of Chemistry and Life Sciences, chairing the plenary session
Following Assoc. Prof. Chinh, Assoc. Prof. Dr. Nguyen Thi Anh Tuyet delivered a speech expressing her gratitude to the scientists, experts, and staff involved in the conference. She stressed the importance of feedback and discussions in refining the research outcomes of the S-IRCLE project, as the project nears its conclusion by the end of this year.
Prof. Vera Susanne Rotter (presents online) and Ms. Hoang Trang, S-IRCLE Project Coordinator - Technical University of Berlin
The conference also featured online presentations from experts such as Prof. Vera Susanne Rotter, Mr. Marcel Spahr, and Hoang Trang, who presented research on H₂S treatment in biogas plants and the use of post-filter materials as fertilizers for crops. Her presentation received in-depth questions and discussions from Assoc. Prof. La The Vinh and considerable interest from audiences.
