Entreposage frigorifiqueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Chilling is considered an alternative curing method for salt-free short-term preservation of hides and skins, but no systematic studies has been carried out with this method. In the present study, an attempt was made to investigate the role of chilling temperatures on the preservation efficacy. The experiments were done in a cold temperature cabinet using goat skins and cow hides. The samples of the hides and skins, chilled to different temperatures, were analyzed for the bacterial count, soluble nitrogen and hydroxyproline. The data suggested that 4oC is the optimum temperature for 7 days storage. The results of the chilling profile study indicate the need for a blast chiller to chill down to the target temperature in less than 2 hours in order to minimize the chance for bacterial damage. The optical microscopic studies of the chilled hides and skins at different temperatures show that the fiber compaction increases with the decrease in temperature compared to the skins preserved with common salt. The leathers produced had also the required qualities and strength properties to fulfill the trade requirements as evidenced from the organoleptic assessment, physical testing and scanning electron microscopic studies.

TraçabilitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The cattle population in Brazil exceeds 200 million, with over 70 million located in the Amazon biome. Approximately 70% of cleared areas in the Amazon house cattle and the population has been reported to be increasing in recent years.
Agriculture is a major driver of Brazil's economy and cattle play a vital role, acting as a key source of revenue for communities in those areas. As a by-product of the meat industry, leather can originate from animais reared in these regions. Due to its significant cattle herd, Brazil is a key source of global rawhides..
Deforestation in the Amazon has also been increasing over the last decade, mainly due to the economic reliance on commodities produced in this area. Organisations need to work with their supply chains and act now to prevent the Amazon from reaching its tipping point for recovery.
The rise in Amazon deforestation is causing the leather industry to face increasing pressure to ensure its supply chain does not contain products linked to deforestation. Although leather is a by-product and, therefore, is not the primary driver of deforestation, the industry is in a prime position to work with supply chains to encourage best practices while maintaining Brazil's social-economic priorities.Note de contenu : - Role of tanneries

Recyclage (déchets, etc.)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The production of biopolymers from leather waste is an important and notable process on the tanning waste management research. The basic aim of the present work is the conversion of non-tanned solid wastes from the tanning industry (splits, defective hides) into high added value biopolymers. Those collagenic biomaterials are at the forefront of potential new applications in tissue engineering within fields such as cosmetics, medicine or veterinary. This treatment will entail a great progress in both environmental and economical terms. The first stage of the project was centered on finding, through a factorial experimental design, the most suitable treatment for the isolation of biopolymers. The effect of variables such as: level of grinding (surface area for chemical interaction); chemical treatment (acid, alkaline and neutral medium); time; temperature and agitation, were studied. Those extracted biomaterials could be formulated according to future application as gel, film, sponge or fibers. All the biopolymers obtained through this process were characterized in order to ascertain the significance of the variables studied. “Tailor-made” biopolymers will be designed, with the desired molecular weight, polymorphic formulation (form), optimized properties and characteristics, that is, perfectly adapted to their future applications.

TannageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The fish production chain presents losses of up to 35%, generating a large amount of waste. Using these residues to produce valueadded materials boost fish production towards a sustainable path. The use of fish skin to obtain leather is increasingly attracting the market for fashion and luxury products. Besides considered an exotic material with a unique design, fish leather also has good mechanical properties. Due to the morphology of fish skin, different mechanical responses can be observed, depending on the leather cutting direction. However, there are no specific technical standards for sampling this material. In this scenario, 45 Tambaqui skins were tanned with chromium associated with oxazolidine, and the mechanical properties of the leather were evaluated in four cutting directions: parallel, perpendicular, dorsal-ventral and ventral-dorsal, all concerning the cephalocaudal line of the fish. Skin and leather micrographs revealed layers of parallel collagen fiber bundles distributed in superimposed layers oriented obliquely to the preceding one. Insertions of collagen fibers perpendicular to the leather surface were also observed, joining the deeper layers to the superficial layers. Tensile strength (TS) and elongation (E) results indicated statistical differences, with higher TS results for the perpendicular cut and greater elongation for the parallel cut. The tear strength was higher for the ventral-dorsal cut, statistically differing from the parallel cut. The data indicate that the cutting direction of the specimen can influence the physical-mechanical behavior of the leather, reinforcing the importance of standardization for the qualitative evaluation of fish leather.
