Proceedings of the 5^th International Conference
of Recent Trends in Environmental Science and Engineering (RTESE'21)

On behalf of the International Academy of Science, Engineering and Technology (International ASET Inc.), the organizing committee would like to welcome you to the 5^th International Conference of Recent Trends in Environmental Science and Engineering (RTESE'21).

RTESE'21 is aimed to become one of the leading international annual conferences in the fields related to environmental science and engineering. This conference will provide excellent opportunities to the scientists, researchers, industrial engineers, and university students to present their research achievements and to develop new collaborations and partnerships with experts in the field.

RTESE is a series of international conferences held yearly. These conferences focus on all aspects of environmental science and engineering. Due to COVID-19, we have made the decision to hold the 5th International Conference of Recent Trends in Environmental Science and Engineering (RTESE'21) virtually this year.

In the fifth meeting of this conference, four keynote speakers will share their expertises with the aim of exposing participants to a wide spectrum of applications, and to foster crosspollination of ideas and develop new research interests. In addition, approximately 10 papers will be presented from professors, students, and researchers across the world.

We thank you for your participation and contribution to the 5^th International Conference of Recent Trends in Environmental Science and Engineering (RTESE'21). We wish you a very successful and enjoyable experience.
