Titre : The ecological challenge of producing leather Type de document : texte imprimé Auteurs : Alois Püntener, Auteur Année de publication : 1995 Article en page(s) : p. 206-219 Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The tanner's responsibility for active environmental protection is being assigned more and more importance in today's society. The reduction of pollution in tannery waste is being tackled on three fronts. Firstly, tanneries are optimizing and reducing their overall chemical consumption and improving waste-water purification. Secondly, tanneries are more efficient in their use of chrome, and are selectively employing non-chrome procedures. Lastly, recycling of leather production waste is now being more actively promoted. This paper will present a simple environmental balance scheme and show a new tanning system which supplements existing tanning procedures. This innovative approach is to pickel the skins with an organic polymeric sulfonic acid without adding salt in the float. It is then pretanned with a penetrating glutaraldehyde formulation or a suitable syntan, forming a stabilized wet white. The influence on the subsequent wet-end processing as well as the flexibility to produce different leather is described. The practical experiences with this system will be discussed and the possiblities of waste recycling, reuse and other benefits will be shown. Note de contenu : - COD and salt in the beamhouse

Titre : Composting of wet white leather waste Type de document : texte imprimé Auteurs : Alois Püntener, Auteur ; N. Gschwind, Auteur Année de publication : 1995 Article en page(s) : p. 220-224 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : The catchphrase "clean technology" and the publicity slogans "biological leather" and "eco labels" have spread to tanning and the leather processing industry, and have some-times led to confusion amongst tanners and consumers. Not being protected in some countries, the word "bio" (biological) is encountered very frenquently. "Bio" is used as a sales-promoting prefix for the most widely varying consumer products. Food, cleaning products and garments in particular are frequently labelled "bio". Highly committed to this philisophy, leather-processing organization are considering what is to be understood by "biological leather". The following properties have already been mentioned: metal-free leather dyed with water-soluble organic or natural dyes, and if finished at all, then only with aqueous processes.
Unfortunately, the prefix "bio" is not reputed everywhere for giving accurate information about product. Therefore, proper consideration should be more point in considering whether a standard eco label would provide more information for the consumerNote de contenu : - Clean technology
