On December 23, 2020, the smelting shop in the village of Nikel carried out the last melting and was stopped forever. The workshop began to be built back in the 30s, when this territory belonged to Finland, and the village was then called Kolosjoki. At the end of World War II, when the territory was ceded to the Soviet Union, the destroyed plant was restored, and the village was named Nikel. It is located west of Murmansk, a few kilometers from the Norwegian border. In the 1980s, the plant emitted about 400 thousand tons of sulfur dioxide into the air per year, and in 1990 an environmental campaign was even launched in Norway to Stop the Soviet Death Clouds. The Norilsk Nickel company, which took over the mining and metallurgical plant in Nikel in the 1990s, initially agreed with Norway on the modernization of enterprises on the Kola Peninsula, but then abandoned the program. In the end, Norilsk Nickel, the largest supplier of non-ferrous metals to the world market, decided to close the smelter on the border with Norway, promising workers social guarantees, transfer to other company enterprises, retraining, pensions, and a small business development program for the village and, for example, industrial tourism.
