Produits de conservation du cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Fatliquors for leather are usually very complex products. The major part of a natural based leather fatliquor consists of processed natural oils or substances derived from them. Furthermore, there can be emulsifiers, crude oils, antioxidants and various auxiliaries improving the penetration of the lubricating components and/or the stability of the formulation.
Fish oil has for many decades been the most prominent raw material used for leather fatliquors. The main advantage of fish oil in application is the high level of softness it creates in leather. By means of sulphitationor sulphation, fish oil can easily be transformed into the anionic, lubricating material which effectively prevents the leather fibres from sticking together.
With the premise to produce eco-friendly leather articles, one has to ask, how sustainable is the use of fish oil in comparison with its most important alternative, vegetable oils ? This paper provides an overview of the sustainability of both oils and the advantages of replacing fish oil with alternatives that have a better eco-profile.Note de contenu : - Sustainability of fish oil versus vegetable oils

Liquides ioniques
Morphologie (matériaux)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather processing is known to impact the environment, especially the pre-tanning processes. Lime sludge is one of the major concerns for the industry. Application of ionic liquid (1- butyl 3- methylimidazolium chloride) instead of conventional reliming practice can reduce this problem to a large extent. In this study, the effect of different unhairing process on the fiber opening using ionic liquids has been studied. The extent of fiber opening was assessed for both control and experimental pelts through SEM analysis. The experimental pelts were found to have better fiber opening than the control. The ionic liquid fiber opened pelts were tanned and the spent liquors were assessed for the chrome content, COD, TDS. The results indicate that all the environmental parameters are better or on par with the conventional process. The final leathers made were also found to have physical characteristics similar to that of conventionally limed leathers.

Industrie 4.0Le concept d’Industrie 4.0 correspond à une nouvelle façon d’organiser les moyens de production : l’objectif est la mise en place d’usines dites "intelligentes" ("smart factories") capables d’une plus grande adaptabilité dans la production et d’une allocation plus efficace des ressources, ouvrant ainsi la voie à une nouvelle révolution industrielle. Ses bases technologiques sont l'Internet des objets et les systèmes cyber-physiques.

NumérisationIndex. décimale : 670.427 Mécanisation, automatisation, robotisation des opérations Résumé : The concepts of Circular Economy and Industrial Symbiosis are nowadays considered by policy makers a key for the sustainability of the whole European Industry. However, in the era of Industry4.0, this results into an extremely complex scenario requiring new business models and involve the whole value chain, and representing an opportunity as well. Moreover, in order to properly consider the environmental pillar of sustainability, the quality of available information represents a challenge in taking appropriate decisions, considering inhomogeneity of data sources, asynchronous nature of data sampling in terms of clock time and frequency, and different available volumes. In this sense, Big Data techniques and tools are fundamental in order to handle, analyze and process such heterogeneity, to provide a timely and meaningful data and information interpretation for making exploitation of Machine Learning and Artificial Intelligence possible. Handling and fully exploiting the complexity of the current monitoring and automation systems calls for deep exploitation of advanced modelling and simulation techniques to define and develop proper Environmental Decision Support Systems. Such systems are expected to extensively support plant managers and operators in taking better, faster and more focused decisions for improving the environmental footprint of production processes, while preserving optimal product quality and smooth process operation. The paper describes a vision from the steel industry on the way in which the above concepts can be implemented in the steel sector through some application examples aimed at improving socio-economic and environmental sustainability of production cycles.

Langues : Américain (ame) Catégories : Acétone L'acétone en chimie, (nom officiel IUPAC propanone, aussi connue sous les noms de diméthylcétone, 2-propanone, propan-2-one et béta-cétopropane), de formule chimique CH3COCH3 est le composé le plus simple de la famille des cétones. C'est un isomère du propanal.L’acétone est un liquide transparent, inflammable, d'odeur caractéristique (plutôt fruitée). Sa température de fusion est de -95,4 °C et celle d'ébullition de 56,53 °C. Elle a une densité relative de 0,819 (à 0 °C). C'est un composé très soluble dans l'eau (c'est une molécule polaire à chaîne carbonée courte), dans l'éthanol et dans l'éther. L'acétone est le dérivé le plus simple de la série des cétones aliphatiques et la présence de la double liaison carbone-oxygène lui confère l'essentiel de sa réactivité.

TannageIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The purpose of this work is to compare the environmental impact of two systems for processing bovine leather: (i) a new continuous system that consists in dehydration and tanning and post-tanning by immersion versus (ii) the traditional system using drums.
In order to better assess the environmental impact of this new tanning system, the life cycle assessment methodology has been chosen to perform calculations on various impact categories, including the global warming potential (CO2 equivalent emissions), and the energy consumption for both the traditional and the new tanning processes.
When assessing the environmental impact of the new system, it is clear that a reduction in the use of acetone during the process will positively affect the environmental outcomes. In this regard, results show reductions on the impacts in eight out of the eleven impact categories analyzed as well as reductions on energy consumption. However, the acetone loss considered (5%) led to higher impacts compared to the traditional system in three specific impact categories, which can be improved by reducing the acetone emission to 2.5%.Note de contenu : - MATERIALS : Goal and scope - Material - Dehydration process - Tanning and post-tanning by immersion of dehydrated hides - Life cycle assessment methology
