The northwestern region of Rio de Janeiro has an important local productive arrangement for processing ornamental and cladding rocks. This activity is responsible for much of the local income, employing a large number of people. The main producer in the region is the municipality of Santo Antônio de Pádua - RJ, with 154 companies (78 quarries and 76 sawmills). The extensive rock extraction and processing activity has caused environmental problems in the region, since during the production stages much is lost due to rudimentary techniques and failing in the treatment of effluents, which ends up generating impacts on the Pomba River, where they are launched. The objective of this investigation was to make a diagnosis of the use of water in the production process, and then evaluate the different alternatives for optimum consumption and treatment of effluents in order to minimize environmental damages. Some exploratory case studies, literature review, interviews with owners, employees, professionals related to the rock sector, and technical visits to companies in the region were carried out. The results point to a lack of preparation and technical knowledge of the entrepreneurs and employees regarding the use of new technologies to help with environmental issues, with regard to the treatment and consumption of water, especially for small companies.Downloads
