The conference invited scholars and experts in the fields of environmental engineering, ecosystems, biotechnology, nanomaterials, and chemical technology from various universities to participate in the review and guidance of this conference. EENCT 2024 aims to provide an international cooperation and exchange platform for experts and scholars to share their research achievements, discuss the key challenges and research directions, and jointly promote the industrialization cooperation and continuous innovation. This collection of proceedings compiles oral and paper presentations submitted by the authors and scrutinized by the special committee. The opening ceremony was held in the main venue and a speech was delivered by the invited speaker. After the main venue, we divided the invited authors into 2 groups. Each author spoke for about 10-15 minutes on detailed material in the slides, with the same amount of time set aside for questions and discussion. This conference has brought together many excellent works and the latest ideas and concepts. We wish to thank all authors and participants for providing their valuable contributions for this proceeding as well as the reviewers for their constructive recommendations and criticism aiding to improve the presented articles.
