University of ra England offers scholarship to agribusiness professionals interested in learning technique that reduces up to 70% water consumption in the tannery
(Industrialization: the current process consumes an average of 30 cubic meters of water per ton of salty skin, Ernesto Rodrigues)
Brazil is the third largest producer of leather in the world, behind only Italy and China, with annual production of 40 million cattle hides. However, more than 700 Brazilian tanneries in operation contend for decades to lower water consumption and energy during the industrialization process of the leather. After all, all stages, from skinning the skin, the operation of river - cleaning and removal of the epidermis and hypodermis - and tanning, to the leather finishing, consume on average 30 cubic meters of water per ton of processed salty skin. With an eye on cost reduction and more sustainable production, the center of Research and Development for Creative Leather Technologies, University of Northampton, in the heart of England, has developed a technique that can decrease by up to 70% of water in the spent tanneries. The details of the study, which is similar to the reuse system developed by Embrapa Beef Cattle in Campo Grande (MS), will be open from next year the Brazilian students, who may apply for scholarships. According to the vice-chancellor Nick Petford, the University has an interest in sharing this research with Brazilian industry of leather, also formed by large companies that sell the product. "The high water consumption can contribute tanning, in some cases, up to an imbalance water" said Petford. In 2012, sales of leather totaled U.S. $ 2 billion in the country
According Petford, the education center for leather in existence for over 100 years and has hundreds of ongoing projects. Besides the technique of reduction in water consumption, another project makes the leather extremely thin, lightweight and resistant to impacts caused by fire and cuts. "This provides a great value for applications including sports and the automotive, aircraft and fashion."
Embrapa's laboratories, research water reuse consist of a closed circuit that separates the effluents of tanning, removes pollutants and returns the water to new tanning. Embrapa has also done experiments with water treatment plant for sewage instead of industrial water withdrawal or underground, as they normally tanneries. According to the researcher responsible for the study of Embrapa, Manuel Antonio Chagas Jacinto, the results have been positive. According to him, for every thousand pounds of bovine skin are produced, on average, 250 pounds of finished leather and 600 pounds of solid waste, which represent a great potential polluter. Already the high energy consumption is recorded especially in the drying, heating water baths and drive the equipment at the treatment plant effluent and dyeing tanks, called fulões.
