[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 96, N° 6 (11-12/2012) . - p. 225-233 Titre : Alternative fungicides for the leather industry : application in various processes Type de document : texte imprimé Auteurs : Sara Cuadros, Auteur ; M. Angels Manresa, Auteur ; Joaquim Font, Auteur ; M. Elena Bautista, Auteur ; Rita Puig, Auteur ; Agusti Marsal, Auteur Année de publication : 2012 Article en page(s) : p. 225-233 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Concentration minimale inhibitrice (antimicrobiens) En microbiologie, la concentration minimale inhibitrice (CMI) est la plus faible concentration d'un produit chimique, généralement un médicament, qui empêche la croissance visible d'une ou de plusieurs bactéries. La CMI dépend du micro-organisme considéré, de l'être humain affecté (in vivo uniquement) et de l'antibiotique lui-même. La CMI est déterminée en préparant des solutions du produit chimique in vitro à diverses concentrations croissantes, en incubant les solutions avec des groupes séparés de bactéries en culture et en mesurant les résultats en utilisant une méthode de dilution standardisée (agar ou microdilution). Les résultats se classent ensuite comme "sensible", "intermédiaire" ou "résistant" à un antimicrobien particulier en utilisant un point d'arrêt. Les points d'arrêt sont des valeurs convenues, publiées dans les directives d'un organisme de référence, comme le US Clinical and Laboratory Standards Institute (CLSI), la British Society for Antimicrobial Chemotherapy (BSAC) ou le Comité européen sur les tests de sensibilité aux antimicrobiens (EUCAST). On a pu constater des écarts importants au niveau des points d'arrêt de divers pays européens au fil des ans, et entre ceux de l'EUCAST et du CLSI. Alors que la CMI est la concentration la plus faible d'un agent antibactérien nécessaire pour inhiber la croissance visible, la concentration bactéricide minimale (CBM) est la concentration minimale d'un agent antibactérien qui entraîne la mort bactérienne. Plus la CMI est proche de la CBM, plus le composé est bactéricide. La première étape de la découverte d'un médicament est souvent le dépistage d'un médicament candidat de banque de données pour les CMI contre les bactéries d'intérêt. En tant que tels, les CMI sont généralement le point de départ pour de plus grandes évaluations précliniques de nouveaux agents antimicrobiens. Le but de la mesure de la concentration minimale inhibitrice est de s'assurer que les antibiotiques sont choisis efficacement pour augmenter le succès du traitement.

The fungicidal capacities of alternative compounds diiodomethyl p-tolylsulfone (DIMPTS), 3-iodo-2-propynyl N-butylcarbamate (IPBC) and thiabendazole/2-Thiazol-4-yl-1H-benzo imidazole (TBZ) were compared to those of conventional fungicides, 2-(thiocyanomethylthio)-1,3-benzothiazole (TCMTB) and the mixture of phenolic compounds). This fungicidal capacity was evaluated against different strains of fungi in different processes. Fungicides were applied in the chrome tanning process, fatliquoring of hides tanned with vegetable extracts and a preservative pickling process. Further studies consisted of a microbiological control samples inoculated with fungi common in tannery, determination of the fungicide content on the skin, and a toxicity study of process wastewater. The results obtained in an earlier work and the higher antifungal capacity of DIMPTS and IPBC in the different processes, supported the possibility of using them in the leather sector. The skins produced using alternative fungicides showed no stains or other defects, and in relation to the environmental impact, toxicity from wastewater was lower in the case of the alternative products against those commonly used.

Biotechnological sequestering of chromium (III) from post-tanning effluents : first results / J. Lalueza in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CV, N° 7 (07/2010)  

[article]  inJOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA) > Vol. CV, N° 7 (07/2010) . - p. 214-221 Titre : Biotechnological sequestering of chromium (III) from post-tanning effluents : first results Type de document : texte imprimé Auteurs : J.

Langues : Américain (ame) Tags : 'Effluents  post-tannage'  Chrome(III)  'Séquestration  biotechnologique'  'Mycètes  acidophiliques' Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Heavy metals in waste waters and sludge may cause significant environmental problems, and it is known that conventional recovery technologies cannot always achieve satisfactory treatment. For example, they are inappropriate to completely recover the chromium in the case of waste waters from the tanning process. Chromium can be recovered (by precipitation) from effluents that contain high concentrations of this metal. However, effluents from the later stages in present day tanning process often have a low concentration of chromium that cannot be recovered and is found in the sludge of the waste water treatment plant (WWTP). The aim of our research is to recover and reuse the chromium (III) from post-tanning effluents by means of a biotechnological sequestering method using acidophilic fungi. In this study, we tested acidophilic fungi capable to grow in the presence of chromium in waste waters from various stages of a real post-tanning process. When the post-tanning process was carried out on a pilot plant scale in which conventional rechroming and neutralization stages were undertaken and the use of additional chemicals was avoided, chromium (III) sequestration values of above 95% were obtained. As these results are so promising, further studies will focus on searching for more resistant fungal strains and determining which of the chemicals used in the post-tanning process can be avoided or replaced by alternatives.

The indicators used for this environmental evaluation are: global warming potential (GWP) and energy return on investment (EROI). The contribution of each process-step in both GWP and EROI was determined. Transesterification of fat to obtain the BDF has been proved to be the most significant step in the process, mainly due to the consumption of methanol. A comparison between BDF and petroleum diesel obtained from non-renewable oil has also been performed using the same indicators. The results show a clear preference for BDF, although data from industrial real plants has to be considered in further works for BDF process to provide more accurate results.

Tannage Résumé : This paper analyzes, from a life cycle perspective, the environmental performance of a newly developed chromium-free tanning process compared to the conventional one, in China. Both processes were evaluated by using carbon footprint, energy consumption and toxicity indicators. Chromium-free tanning process has been found to significantly reduce the considered impact categories compared to conventional tanning. The impact contribution of each process step was calculated, with the tanning step being the major contributor. Results show that the production of chemicals used in the tanning process, have a significant effect on the impacts evaluated. Some of these chemicals have been substituted with similar ones (used as proxies) when no manufacturing-data was available in the databases. Thus, it is important for future and more precise LCA studies to develop databases on the specific chemicals used. This study is a first estimation of the impacts and will help on the decision of expending time and efforts on developing and optimizing the new technology. The results show that it is interesting to use this LCA methodology to environmentally evaluate new research processes and products, before industrial scaling and implementing them, to optimize research time and efforts towards the most environmentally promising products and processes.

The measures taken to reduce greenhouse gas emissions, and the significant and increasing awareness on the environmental impact of the production processes, force leather manufacturers to meet higher environmental standards and improve the sustainability of the leather tanning process. The leather industry is one of the significant sectors of the Turkish economy in terms of industrial production, employment and export earnings. However, there is a gap in the literature regarding a carbon footprint assessment of the Turkish leather industry. It is important to analyse the leather production processes in order to identify the 'hotspots' and environmental improvements that could transform the constraints into opportunities for improving the environmental performances of Turkish tanneries. Considering these aspects, this study aims to provide basic information, and raise awareness of carbon emissions and energy efficiency in Turkish leather production. Note de contenu : - FIGURES : 1.
