Lime fleshings, one of those solid wastes, are a very important fat source although normally they are not used and are disposed off representing a high cost for tanners. A process to recover fat from such fleshings was developed, introducing a new value-adding route through the use of fat for biodiesel production. Biodiesel obtained from this fat material was characterized by parameters according to EN 14214 standard, showing good accordace in almost all of the evaluated specifications. However, we still needed to adjust the process in order to improve parameters, like moisture and ester content, that are close we still needed to adjust the process in order to improvve parameters, like moisture and ester content, that are c lose to the limits. An economic evaluation of the fat recovery and usage as raw material for biodiesel production was done, showing an economic potential when compared to vegetable oils. It was demonstrated that a fat selling price of 350 E/ton, with some margin for reduction, is possible. This price is better than the normal price of vegetable oils, which lies between 500 and 700 E/ton.

Taylor, Auteur ; Luisa F. Cabeza, Auteur ; William N. Marmer, Auteur ; Eleanor M. Brown, Auteur ; C. J. Thompson, Auteur ; Edward J. Diefendorf, Auteur Année de publication : 1997 Article en page(s) : p. 5-13 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Tannage chrome Extraction sous-produits collagène Déchets solides Industrie cuir Traitement alcali enzymes Produits hydrolisés Recyclage Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In the United States, over 60 000 metric tons of chromium containing solid waste is generated by the leather industry each year, and approximately ten times this amount is generated world-wide. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. We have developed two processes in which this waste is treated with alkali and enzymes to extract hydrolyzed and gelable protein products and a recyclable chromium cake. We have demonstrated that these processes are repeatable with respect to their chemical and physical properties and that good and repeatable material balances are obtained. The isolated chromium can be chemically treated and recycled into the tanning process. The recovered protein fractions, practically devoid of chromium, could be used in a wide range of products, including adhesives, cosmetics, films, animal feed and fertilizer.

Titre : Research progress on resource utilization of leather solid waste Type de document : texte imprimé Auteurs : Yanchun Li, Auteur ; Ruijun Guo, Auteur ; Wenhui Lu, Auteur ; Deyi Zhu, Auteur Année de publication : 2019 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Boues d'épuration -- Recyclage
Cuirs et peaux -- Déchets -- RecyclageTags : 'Déchets solides de cuir' cheveux tannerie' non tannés' cuir contenant du chrome' 'Boues fini' Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather making is the process of converting raw hides into leather. Amounts of solid waste containing hazardous and high value components are generated during this process. Therefore, the elimination of the potential pollution and resource utilization of leather solid waste are the primary research hotspots. Herein, we comprehensively review the recent advances in the resource utilization of leather solid waste generated from chrome tanning including the utilization of tannery hair waste, untanned solid waste, chrome-containing leather solid waste, tannery sludge and finished leather waste, emphasizing on the general and novel utilization approaches. Finally, the remaining challenges and perspectives were summarized, in order to accelerate the development of resource utilization of leather solid waste.
