Preface: 9th International Conference on Environmental Science and Material Application (ESMA 2025)

The organizing committee is proud to present the proceedings of the 2025 9th International Conference on Environmental Science and Material Application (ESMA 2025), held in Lisbon, Portugal during April 26-27, 2025. We warmly welcome prospected authors submit new research papers to ESMA 2025, and share the valuable experiences with the scientist and scholars around the world. The conference is an international forum for the presentation of technological advances and research results in the fields of natural resources, environmental science, environmentally friendly materials, green energy and power engineering. The conference will bring together leading researchers, engineers and scientists in the domain of interest from around the world. By submitting a paper to ESMA 2025, the authors agreed to the review process and understood that papers would undergo a peer-review process. Manuscripts were reviewed by appropriately qualified experts in the field selected by the conference committee, who took detailed comments and the authors would submit a revised version that took into account this feedback. All papers were reviewed using a double-blind review process: authors declared their names and affiliations in the manuscript for the reviewers to see, but reviewers did not know each other's identities, nor did the authors receive information about who had reviewed their manuscript. The committees of ESMA 2025 invested great efforts in reviewing the papers submitted to the conference and organizing the sessions to enable the participants to gain maximum benefit. We do believe your great participation will make our conference success and we would appreciate your participation. With our warmest regards, Conference Organizing Chair Lisbon, Portugal
