The Society for Process Engineering and the Society of Thermal Engineers of Serbia, with the co-organization of the Serbian Chamber of Commerce, are organizing two conferences Procesing 24 and IEEP 24, which will held at the same time and with a common part of the program in the period from May 29 to 31, 2024. The conferences will be held at the Serbian Chamber of Commerce in Belgrade, Serbia.

IEEP '24 will be held 30 years after the first conference entitled "Industrial Energy" of the then Society of Thermal Engineers of Yugoslavia, which acquired an international character in 2008 and changed name to "Industrial Energy and Environmental Protection in the Countries of Southeast Europe". Since 2008, eight regional IEEP conferences have been successfully held. That is why the upcoming IX conference has a special significance and reflects 30 years of successful work of the Society of Thermal Engineers and its Section for Industrial Energy.
