Notices and program

The convention of scientists, specialists and students on the topic of environmental protection in the Republic of Croatia (4th ZORH convention) is a project organized by the students of Faculty of Chemistry and Technology in Split, with the assistance of scientists and scientific staff of the faculty. The first ZORH convention was held on the 5th of March, 2018. It enabled us to connect a large number of people from different institutions and to initiate new projects. After two successful ZORH conventions, this year’s 4th ZORH convention will have an international character. The convention is co-organized by Technical University of Košice and the Student section of the Croatian society of chemical engineers and technologists.

The goal of the 4th ZORH convention is to connect the academic community with the industry, in order to discuss key problems and to further stimulate public interest in environmental protection. We also want to encourage other students to critically and responsively approach future work which will have a large impact on the environment. Advancement of knowledge and mutual aid is the only solution for a better future, and so we would like to invite you to join and help us attain that better future.
