was inaugurated. The unit was expanded in 1966, a year that also saw the introduction of a system for agglomerating concentrates of zinc and lead.
This was the culmination of a four-year program of thorough restructuring and modernization, with the new equipment having a capacity of 30,000 tons of zinc and 20,000 tons of lead bullion per year. The 1967-1970 period saw the introduction of an electrolytic lead refining system (capacity 24,000 tons a year); a unit for extracting metallic bismuth for technical and pharmaceutical use from anode sludge, as well as gold and silver alloys and

In 1984, a second blast furnace began operation, so that the old components built from 1939 to 1957 were retired. Between 1985 and 1989, zinc powder production began and a system for collecting residual gases was put in place.
In 1988, a 250 m high chimney was built. By 1989, the plant was annually generating 43,490 tons of sulfuric acid (against a projected capacity of 126,000 tons), 23,519 tons of electrolytic lead (below the 38,000 tons projected), 29,840 tons of pure zinc, 2,094 tons of zinc powder, 19 tons of cadmium, 29 tons of bismuth and 195 tons of antimony.
The communist regime, which considered the factory crucial to the national economy and did not export its products,
collapsed in 1989. Starting in 1990, production continuously fell, reaching 25% of its former level. However, output recovered to 1989 levels in some categories in 1995-1996. Starting in late 1992, efforts at updating the plant were made, including better gas purification at the agglomeration unit and blast furnace, completion of the tall chimney and a new dust filtration and water recirculation system. By 1997, some 40% of employees were laid off.

In early 2009, during the
Great Recession
The Great Recession was a period of market decline in economies around the world that occurred from late 2007 to mid-2009. , due to a major fall in zinc and lead orders, 80% of employees or over 700 people were laid off. The remainder were kept on for equipment maintenance, and the factory was temporarily shut down. Including their dependents, this measure affected nearly a third of the town's inhabitants, as well as provoking significant losses to the town budget.
Over the years, the company has been known as Sonemin, U.C.M., 21 Decembrie and I.M.M.N., acquiring the Sometra name in 1991.

The company's products were the chief raw materials for various objects made of rubber (tires, transmission belts, conveyor belts, protective clothes and shoes), but were also used in the chemical, pharmaceutical, agricultural and other industries.

By the early 1990s, Copșa Mică was among the most polluted towns in Eastern Europe.

In 1977, 70 residents had excessive or dangerous lead levels, a figure that had risen to over 400 by 1990, when over half of Sometra employees had above-normal lead.
One test of nearly 3000 residents showed over half had lead poisoning. From 1983 to 1993, some 2000 people were hospitalized due to lead-induced anemia or severe lung and stomach pains. Of local children aged two to fourteen, 96% had chronic bronchitis and respiratory problems.
Studies of children seven to twelve years old from Copșa Mică and Mediaș found that many showed signs of mental retardation, two-thirds were underweight and 30% of boys and nearly half of girls had high blood pressure. Five babies were born with malformed hearts between 1977 and 1983, a number that rose to 16 in 1988 alone. In 1985, a local doctor wrote a detailed report that ended up in the hands of dictator

Residents were dependent on the factory for their livelihood, saw the pollution as part of reality and were reluctant to agitate for change.
Effect on vegetation
Local authorities became aware of damage to vegetation caused by the factories by the early 1960s, a phenomenon that widened and intensified over time. In 1961, some 100
ha of trees, those in direct proximity to the sources of pollution, were afflicted. This figure had risen to 1650 ha by 1973 and nearly 8000 ha in 1978. Studies in 1988 and 1999 revealed that the entirety of the forests managed from

Natural regrowth of forests has been made more difficult in the least polluted areas, while in the severely to moderately polluted zones, it had stopped completely or was trending in that direction by 2008.

and elevated acidity. For instance, between 1994 and 1998, planting yielded a success rate of between 12 and 95%. Erosion, landslides and repeated fires have taken place, and trees' beneficial effects on climate, water and air quality have been seriously diminished or eliminated.
Replanting of intensely polluted soil started in 1988 and by 2008, 644 ha had been replanted, with the
Black Locust proving especially well adapted, among other species.
[Reconstrucția..., p.18, 20] Upon privatization of Sometra in 1998, the government, in accordance with a 1995 law, stipulated that fourteen steps would have to be taken by 2002. These would lessen the plant's environmental impact by reducing gas and toxic dust emissions. One step was to plant 40-50 ha of trees on the banks of the
Târnava Mare River; trees paid for by the company were planted on 35 ha between 2000 and 2003.
With Sometra shuttered, the year 2010 marked the first since measurements were taken that air pollution did not exceed legal limits. Plants began to regrow in forests that were shrinking as late as 2001. Whereas moles and hedgehogs had disappeared and rabbits and deer had migrated to cleaner areas, rabbits, foxes, wild boars and deer later returned. Isolated honeybee colonies and other insect species also reappeared.
