Cana Brava Amianto´s Mining in Minaçu, Goiás, Brazil

Despite its relation to health damage, Brazil still is the third largest producer of amianto (pr asbestos). Cana Brava is the only mine of amianto in Brazil.


Asbestos or Amianto is a mineral able to resist high levels of temperatures. It is used in manufactured products, building materials, and the automobile industry. The World Health Organization (WHO) classifies Amianto as a carcinogen and it was completely banned in Europe since 2005. Nevertheless, in some States of Brazil, the Amianto remains legal. By the end of 1930´s the Amianto consumed in Brazil was imported. The exploration and exploitation began in 1940 when the Anonymous Society of Asbestos Mining (Sama) owned by Saint Gobain (France) settled in Poções (State of Bahia), in Sao Felix do Amianto. The mine operated until 1967, due to the exhaustion of the reserves. The same year (1967) the company SAMA moved to Minaçu (State of Goiás) where they began to explore the mine “Cana Brava”.  Since then, Minaçu  -The Big Mine in tupi-guaraní language- is known as the “capital of amianto”, this is the only amianto mine in operation in Brazil. The Brazilian Association of those Exposed to Asbestos (Abrea) states that contact with amianto represents a serious public health problem. According to with them, because of the exposure to amianto, dozens of people have died of cancer and respiratory diseases. Mesothelioma is one of the most common (this is a type of cancer that develops from the thin layer of tissue that covers many of the internal organs) In the so-called "bed of dust", where the ore was separated, workers, among them many women, were covered with dust. Evandra Vieira Brito, who lost her husband (ex-employee of Sama), with cancer in 2009, remembers: "There were about 20 girls covered by dust. They all died vomiting blood" After that Amianto was banned in Europe, a draft-law initiative was purposed by a senator to the Brazilian parliament in order to ban the extraction, industrialization, importation, transportation, and storage in Brazil.  Nevertheless, SAMA group and the local government of Minaçu are claiming the continuing of their use claiming that this is one of the most sources of employment in Minaçu. And this is true, criticizing amianto mining is endangering the city's only employer. About 70% of the taxes collected by the municipality came from this activity. Groups in favor, have stated that the “way in how amianto is extracted in Minaçu is not damaging health” and that “the company is respecting all the laws related to occupational health”. They also state that the people ill right now in Minaçu it because their get ill in the previous mine (in BA) as some of them also migrated because of work. In this case, (Saint Gobain is the main responsible).  According to a report by the Ministry of Health, 2,400 people have already died from amianto -related diseases between 2000 and 2010. "The trend will increase in the number of cases in the next few years" concluded the report. And this is because the exposure to amianto can lead to the disease up to 10 years after the exposure. The position of the Brazilian government is a controlled use.  Around the world 100,000 people die every year for being exposed to amianto in their work environment (WHO,2006).

Pathways for conflict outcome / responseApplication of existing regulations
Development of Alternatives-To ban the use of asbestos in all Brazil

-Other groups only want to control its use (this is also the position of the Brazilian government)
Do you consider this as a success?No
Why? Explain briefly.Economic arguments prevail over health issues. Despite the health impact, the company SAMA is seeing as the main employer and the motor of the economic activity in Minaçu.
