Research conducted by Tavex allowed for the creation of a project that helps Camargo Corrêa Group to reduce, at the same time, the impact of two byproducts of the jeanswear dyeing and finish process: the CO2 from the combustion of boilers and the alkaline effluent from the fabric treatment processes.
Following the commitment of the Climate Agenda, which establishes the reduction, reuse and storage of carbon, the project collaborators promoted studies and found out that the CO2 could be used instead of other toxic and corrosive acids to bring the alkaline pH of effluents closer to neutral.
The project, started in 2007 at the Tatuí-SP plant, has already been implemented at the units of Americana-SP, Socorro-SE and Tucuman, in Argentina. One of its most important results so far is that Tavex was able to reduce by around 3,000 tons the annual release of CO2 into the atmosphere, a volume that would require the planting of 18,000 trees to offset these gases, according to data from NGO “The Green Initiative”.
Among the additional results, the exchange of acids for CO2 also helped reduce operational accidents, improving the labor safety conditions and the useful life of equipment; minimized the impacts to the environment by making the pH neutralization more effective and favoring the reuse of effluents; and generated savings of R$ 2.5 million to Tavex between 2009 and 2010 by reducing expenses with raw materials and maintenance of machines.
