Short-term researchers (Short term experts)

Two Japanese short-term researchers worked in Thailand with Thai researchers.

18 – 21 Feb. 2025: Dr. Masaaki Morikawa, Chief Researcher, Hokkaido Univ.
19 – 21 Feb. 2025: Dr. Yoshitaka Ebie, G5/G6, National Institute of Environmental Study

Due to the renovation of the central wastewater treatment facility on campus where the duckweed wastewater treatment equipment was installed, the equipment was relocated next to the cafeteria of the Faculty of Engineering in early February. Three tanks were placed in parallel to compare the wastewater treatment speed and evaluate the productivity of duckweed in two duckweed cultivation areas and a control area without duckweed.

In creating the catalog of duckweed biological resources and coexisting microbial resources, opinions were exchanged with Thai researchers on confirming the necessary information and preparing the website for the catalog's publication.

Discussed support for ADGreenFarm (a project member company), workshops, and surveys for the general public.

Had a technical meeting about experiment on measuring the low-carbon impact of the duckweed wastewater treatment system.

In addition to the wastewater treatment (G5) for low carbonization, discussions were also held on the carbon footprint of valuable duckweed production (G4).

With G5 team traveled 190 km north of Bangkok to Lopburi Province and installed two floating chambers at a private pig farm's wastewater reservoir. Due to the seasonal proliferation of duckweed in the reservoir, experiments and measurements will be conducted to compare conditions with and without duckweed. Despite a long day from early morning until 9 pm, the installation was successfully completed thanks to the efforts of the G5 team led by Dr. Chart and the support contractors.

Note:
The project consists of six research groups namely: G1: Duckweed Holobiont Resource & Research Center (DHbRC). G2: Duckweed holobiont collection. G3: Duckweed holobiont analysis and biotechnology. G4: Duckweed biomass utilization. G5: Duckweed wastewater treatment technology. G6: Social implementation activities toward BCG economy.
