Electronic Document Management System (EBYS-Elektronik Belge Yönetim Sistemi) is used in Mersin University. The communication of the university with its internal units and other institutions takes place in computer environment with the EBYS system. In this way, official correspondences are standardized, sending and approval times are shortened. Most importantly, labor, time and raw materials are saved. In this way, the consumption of stationery consumables such as paper, printer, cartridge, toner has decreased significantly. Since the need for raw materials and the consumption of natural resources is reduced, the amount of waste is also reduced. In our university, care is taken to comply with the double-sided printing policy on common printers used in the departments and secretariats of the faculties. Thus, Mersin University protects the environment significantly by reducing waste generation and carbon dioxide emission.
