On the 20th of October, 2020, our traditional tree planting took place near the Regional Children's Clinical Hospital. This environmental campaign was held by Russkaya Kozha and Safyan companies three years running. The employees of the Ryazan Tannery together with the students of the Ryazan State University planted several maples and firs. Then the students went to the tour of the tannery in order to get acquainted with the enterprise.
