Wet-white (tannage)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Despite all the efforts to develop an organic tanning process able to meet the same standards as the chrome tanning and wet-blue production (WB), no universal system has still been developed with the same performance and wide spectrum of applications as chrome tanned leathers.
Assuming that chrome tanning and wet-blue production will still be in use over the next few years, and bearing in mind that chrome shavings and other solid chrome containing wastes represent one of the major problems for disposal or recycling, Trumpler have been develop ng an innovative process designed to reprocess and reuse shavings (from wet-blue or wet-white) in the production of a novel range of green chemicals with a low carbon footprint for the retanning of leather.
Currently chrome shavings are disposed of in landfill or recycled in the production of leather board. Current methods of using chrome shavings include an economic cost to the tanner. The total quantity of chrome shavings produced will be strongly dependent on the kind of article and the process used in each tannery.Note de contenu : - Proposal

Titre : Bioaccumulation route for secured recovery and recoup of chromium from tannery wastewaters Type de document : texte imprimé Auteurs : Rathinam Aravindhan, Auteur ; Balachandran Unni Nair, Auteur ; Jonnalagadda Raghava Rao, Auteur ; Balaraman Madhan, Auteur Année de publication : 2004 Article en page(s) : p. 197-204 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Increasing concern regarding the toxicity and environmental impact of the chromium metal ion discharge from the tannery has led to investigations into alternative effluent treatment technologies. The use of biological materials for heavy metal ion removal and recovery technologies has gained widespread acceptability during recent years because of its high performance at low cost compared to other treatment methodologies. In this work a species of brown seaweed is shown to accumulate chromium from tannery wastewaters. Bioaccumulation provides a cheaper means for the removal of heavy metals; however, the reuse of recovered metal is a challenging problem. The chromium-loaded seaweed was advantageously used as a reductant for the manufacture of basic chromium sulfate. The developed product has been employed for tanning of goatskins. Studies reveal that the quality of the wet blue leathers is on a par with the leathers tanned with commercial BCS. Shrinkage temperature of the leathers is comparable and is above 110 °C at an offer of 1.25% Cr2O3. Chromium exhaustion is about 74%. Performance of the crust leathers is comparable to that of conventional tanned leathers. This methodology provides a holistic approach for the recovery and reuse of chromium from tannery wastewaters.

Tanins végétauxIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The high performance and low price of synthetic chemistries have resulted in their traditional use in many industries, including that of leather. Despite their performance benefits, the environmental footprint of these chemicals has resulted in a need to develop more natural and environmentally friendly alternatives. These alternatives will reduce the demand for fossil resources and replace traditional toxic chemicals with chemicals that exert minimal impact on the environment and human health.
The global-wide effort to replace fossil fuels has led to the development of a bioeconomy in which biobased chemicals play an important role. Biobased chemicals are chemicals that are entirely or partly composed of biological materials.
As one of the most abundant feedstocks provided by our planet, biomass can play a key part in the industry-wide effort to move towards more sustainable leather processing (see Figure 1). Biobased chemistries have the potential to replace the use of non¬renewable fossil resources with renewable, biodegradable and environmentally friendly alternatives.Note de contenu : - Biobased dehairing

Réticulation (polymérisation)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The U.S. hide and leather industries are facing challenges of meeting environmental imperatives; quantifying, maintaining, and improving current hides and leather product quality; developing new processes and products; and improving utilization of waste. One of our contributions to address these ongoing challenges is to develop innovative uses and novel biobased products from hides to improve prospective markets and to secure a viable future for hides and leather industries. We had previously investigated the production of nonwoven and green composites from collagen fiber networks, which were extracted from un-tanned hides and from tannery solid wastes, such as splits or trimmings. Recently, we focused on preparing biobased films from un-tanned; specifically limed hides, which have potential commercial applications in medical care and food packaging. Collagen fiber networks were obtained from hides that have been processed to remove the noncollagenous materials through the hair removal and liming steps. We also focused on understanding the effects of processing steps such as bating and crosslinking treatments on the morphology and physical properties of biobased films from un-tanned hides. Results showed that the concentration of collagen solution and the methods of crosslinking with glutaraldehyde during the film formation process have significant effects on the properties of resultant films. Higher concentrations of collagen and addition of glutaraldehyde crosslinkers after solidification of the films yielded better mechanical properties. The encouraging results of this ongoing research are instrumental to produce biobased films, which have wide applications in both the medical field due to good biocompatibility and the food packaging because of excellent mechanical properties and acceptable edibility.

PyrolyseLa pyrolyse est la décomposition ou thermolyse d'un composé organique par la chaleur pour obtenir d'autres produits (gaz et matière) qu'il ne contenait pas. L'opération est réalisée en l'absence d'oxygène ou en atmosphère pauvre en oxygène pour éviter l'oxydation et la combustion (L’opération ne produit donc pas de flamme). Il s'agit du premier stade de transformation thermique après la déshydratation.
Elle permet généralement d'obtenir un solide carboné, une huile et un gaz. Elle débute à un niveau de température relativement bas (à partir de 200 °C) et se poursuit jusqu'à 1 000 °C environ. Selon la température, la proportion des trois composés résultants est différente.
SolidesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Biochar is the product of the pyrolysis of biomass created in the absence of oxygen. It has a high carbon content and a high stability in the environment.
For the leather industry, biochar production could be used as a cost effective means of waste disposal. It is cheaper than dumping the waste in landfill and decreases the mass and volume of the waste that industry generates, and so is a more economical option for waste disposal than landfill.
Biochar makes leather waste safer for the environment, as it sequesters the chrome that otherwise leaches out of the waste. This in turn has the potential to lower the fees that must be paid for disposing of wastes.
If leather wastes are pyrolysed to biochar, the leather industry will become more environmentally friendly in other ways. There will be less carbon released to contribute to global warming, and in addition biochar can be used to improve soil quality.Note de contenu : - Pyrolysis
