Peroxyde d'hydrogèneLe peroxyde d'hydrogène (H2O2), communément appelé eau oxygénée ou encore perhydrol (appellation industrielle), est un composé chimique liquide et visqueux, aux puissantes propriétés oxydantes (il est aussi réducteur). C'est donc un agent blanchissant efficace qui sert de désinfectant et (à haute concentration) d'oxydant ou monergol dans les fusées spatiales.Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The ever increasing attention to the environmental impact of the process industry imposes an obligation to constantly improve the global sustainability of the tanning process. Among the numerous phases of the tanning process, the beamhouse accounts for most of the total polluting charge, due to the use of sodium sulfide and lime during the manufacturing process of hides. Hence, the authors have recently developed an alternative unhairing process that eliminates the use of sulfides. The actual reduction of the environmental impact of this process, in relation with the traditional one, was evaluated performing a Life Cycle Assesment (LCA) using SimaPro 6, one of the most used software for LCA analysis. Environmental impacts were finally rated using “EDIP 97” assessing methodology. Since impact assessment methodologies were mainly developed for the manufacturing field, EDIP 97 was slightly modified and adapted to fit with the tannery industry.

Titre : Studies on mono and divalent cations effects on hair immunization Type de document : texte imprimé Auteurs : Domenico Castiello, Auteur ; Monica Puccini, Auteur ; Dennis C. Shelly, Auteur ; Sandra Vitolo, Auteur Année de publication : 2007 Article en page(s) : p. 341-346 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Within the studies on the phenomenon of alkali-induced hair immunization, it has been observed that the hair immunization process arising from the action of dibasic alkalis takes place differently than immunization using monobasic alkalis. On the basis of these observations, our work investigated the influence of mono and divalent cations on the hair immunization mechanisms. In our experimental design, fresh salted bovine hides were exposed to mono and divalent alkalis and salts at different concentrations for various time periods. After treatment, the hides were exposed to reducing agents in order to verify the effectiveness of each cation in promoting immunization. We observed that immunization occurs with dibasic cations, but that both a minimum exposure time and a proper alkalinity are required. The appearance of inter and intra polypeptide chain links was investigated by comparing non-immunized and immunized hair using MIR and FIR spectroscopy, ICP chemical analysis and DSC. The chemical and the instrumental analyses indicate that the exposure of hair to divalent cations in alkaline medium, unlike the monovalent cations, induces the formation of cross-links in the keratin structure and promotes immunization. These investigations contribute to confirmation that the immunization process occurs only in the presence of divalent cations. Research work is in progress in order to further understand the nature and the mechanisms of these complex interactions.

TannageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : As a response to the growing concerns about a variety of environmental issues expressed by public opinion and political bodies, the leather industry needs to support its market by environmental criteria as a guarantee of quality. For this reason, assessment tools as Life Cycle Assessment (LCA) methodology, which allow a more thorough knowledge of the products to the enterprises and can help to guide the environmental policies, are recommended (e.g. EC Directive on Ecologic Labels). The LCA methodology, described in details by the ISO 14000 series, allows the assessment of the environmental impacts due to products, processes, or services, by the identification of the inputs (e.g. energy and material consumption) and outputs (e.g. waste and pollutant production) streams exchanged by the process with the environment (i.e. from raw materials procurement to waste streams disposal). The application of LCA as tool for integration of sustainability aspects in process design and development is gaining wider acceptance and methodological development. In this study, the life cycle modeling was used to support the development of a novel tanning process based on the use of a new class of tanning agent produced from renewable resources (e.g. glucose). The experimental activity performed to investigate the technical feasibility of the innovative tanning cycle was supported by the modelling of the process using the LCA methodology in order to assess the environmental performance of the leather production cycle. Therefore, an LCA analysis was performed in order to compare the glucose-tannage process with the traditional one from an environmental point of view. Note de contenu : - Process description
