Preface: 2nd International Conference on Biochemical Engineering and Environmentally Friendly Material (BEEFM 2023)

Abstract

2023 2nd International Conference on Biochemical Engineering and Environmentally Friendly Material (BEEFM 2023) was successfully held online during February 11-12, 2023 in Xi'an, China. The conference invited scholars and experts in the fields of chemistry, biology, environmental engineering and materials application from various universities and institutes, to participate in the review and guidance of this conference. The conference focuses on the latest research fields, and provides an international cooperation and exchange platform for experts, scholars and business managers in these fields.
 The aim of BEEFM 2023 is to share the research achievements, discuss the key challenges and research directions of the development, and jointly promote the industrialization cooperation and continuous innovation of international academic achievements. This collection of proceedings compiles oral and paper presentations submitted by the authors and scrutinized by the special committee.
 Due to travel restrictions and indoor activities related to COVID-19, we were forced to move BEEFM 2023 online. Attendees were notified one month in advance that the on-site conference was changed to an online conference. The online conference was held on the video conferencing software. Because of the wide coverage of this conference and the large number of attendees, we divided the conference into main session and sub-sessions. The opening ceremony was held in the main session and a speech was delivered by the invited speaker. After the main session, we divided the participants into three sub-sessions. Each author spoke for about 15-20 minutes on detailed material in the slides, with the same amount of time set aside for questions and discussion. The format of questioning and discussion was that after each author's introduction, the conference chairman and committee members asked and answered questions. At least one attendee could ask questions that will be answered by the speaker.
 BEEFM 2023 had brought together many excellent works, latest ideas and concepts. New ideas have been provided in the fields of chemistry, biology, environmental engineering and materials application. Look forward to meeting again next year.
