Productive processes associated with metal mining activities generate a series of hazardous waste (heavy metals, acid mine drainage, arsenic, lead, mercury, etc.) that are stored in the form of deposits of mining sludge. One of the greatest environmental risks associated with environmental management of sludge is the danger of uncontrolled leaks, which can acidify and contaminate the soil or infiltrate in the aquifers of the area, causing serious pollution problems.

Creatividad y Tecnología provides technical assistance on environmental issues for companies in the sector in order to design systems able to prevent the generation of polluting leaks and mitigate its effects on the environment where appropriate.
