Thanks to their fruitful long-standing collaboration, Geotechmin OOD and MMTEC signed a Framework Agreement for long-term technical cooperation in 2013, which envisages joint activities on the construction of wastewater treatment facilities in Bulgaria and abroad. The main activity of Geostroy AD is focused on the execution of all works relating to the exploitation of the wastewater treatment plant and effective removal of heavy metals, radionuclides and other pollutants. ‘The project is called “Green Rust”, derived from the name of the pioneering technology developed by the Japanese company,’ said M.Eng. Yordanov at the conference.
