（1）On September 11, 2020, the research group of Professor Shen Wenhao from the State Key Laboratory of Pulp and Paper Engineering of South China University of Technology and members of the foreign research group from Aristotle University of Thessaloniki in Greece held a remote video conference on the stage progress of the project. Two aspects of fault diagnosis in wastewater treatment process and Optimal control of dissolved oxygen for reducing GHG emission in papermaking wastewater biochemical treatment process were discussed. Both sides gave their own views and suggestions on the problems they found in the work. The Greek professor gave careful answers and guidance to the doubts our students encountered in the work. The two sides discussed the follow-up research plan of the project.

（2）On March 19, 2021, the research group of Professor Shen Wenhao from the State Key Laboratory of Pulp and Paper Engineering of South China University of Technology and members of the foreign research group from Aristotle University of Thessaloniki in Greece held the second remote video conference on the stage progress of the project. During the meeting, the Chinese side had an in-depth discussion with the Greek side on the two research contents under the topics of Estimation of N2O emission in papermaking wastewater treatment and Fault diagnosis in papermaking wastewater treatment. In addition, both parties jointly summarized the current research progress of the project and discussed the follow-up research plan in detail.

（3）On April 13, 2022, the research group of Professor Shen Wenhao from the State Key Laboratory of Pulp and Paper Engineering of South China University of Technology and members of the foreign research group from Aristotle University of Thessaloniki in Greece held a remote video conference on the stage progress of the project. In this paper, Advanced control system framework for GHG emission reduction in sewage treatment process, GHG emission mechanism model of paper mill and comprehensive evaluation of GHG emission reduction based on dissolved oxygen control strategy are discussed in depth. Both sides gave their own views and suggestions on the problems they found in the work. The Greek professor gave careful answers and guidance to the doubts our students encountered in the work. The two sides discussed the follow-up research plan of the project.
