Tannage Résumé : Dialdehyde starches with different aldehyde content from native corn starch were prepared by sodium periodate oxidation to be used as a tanning agent in leather making. For this purpose, native corn starch was oxidized with sodium metaperiodate in different molar ratios. After oxidation processes, the yields, solubility in water and aldehyde contents of the obtained dialdehyde starches were determined as well as structure characterizations by Proton Nuclear Magnetic Resonance Spectroscopy, Fourier Transform Infrared Spectroscopy and Gel Permeation Chromatography. Evaluating the gel permeation chromatography data, the dialdehyde starch samples which were thought to be in appropriate molecular weight/size to penetrate into skin fibers were selected to be used in the tanning process. Their tanning abilities were evaluated by investigating hydrothermal stabilities, filling and fiber isolation characteristics and physical properties determined by mechanical tests and organoleptically. From the evaluation of the results, it was revealed that sodium metaperiodate oxidized starches which have appropriate molecular weight and adequate aldehyde content has a remarkable tanning effect and can be utilized as a tanning agent with the advantages of not necessitating pickling process which means saving time and simplifying the production but more importantly offering an important advantage from an environmental point of view.

Assessment of water management in tanneries / Patrice Monteiro de Aquim in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 94, N° 6 (11-12/2010)  

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 94, N° 6 (11-12/2010) . - p. 253-258 Titre : Assessment of water management in tanneries Type de document : texte imprimé Auteurs : Patrice Monteiro de Aquim, Auteur ; Mariliz Gutterres, Auteur ; Jorge Trierweiler, Auteur Année de publication : 2010 Article en page(s) : p. 253-258 Note générale : Bibliogr.

Tannage Résumé : Assessment of water management in tanneries --- This study evaluates the use of water in processing hides into leather. It investigates the environmental impact on water resources of tanneries in Rio Grande do Sul State, evaluating the water demand and concentrations of certain chemicals in the wastewater discharged from the beamhouse, tanning and retanning processes of this industry. A questionnaire was formulated which was intended to identify water management problems in tanneries, and the possible alternatives available to tanneries aiming at their improvement. A simple and objective application called IRGO (insufficient, regular, good and optimal was developed. The IRGO was applied to 10 tanneries. After completing the questionnaire, the tanneries could check how removed they are from an ideal tannery and ascertain which actions must be taken to improve their performance. The results showed that there is a large demand for water in the process and little water is re-used. The most conventional liming process employs sulphide, lime and amine and recycling is already applied to this operation in the state. The steps of washing, deliming and the float itself use large quantities of water, although the majority of the tanneries do not use ammonia in deliming. The tanning procedure most used employs chrome III without recycling. In relation to retanning, studies need to be carried out aiming to increase the efficiency of the absorption of chemicals. The wastewater treatment plants are satisfactory due to the requirements of the environmental organizations.

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. Turkey's electricity mix - 2. Greenhouse gas emission values for each scope - 3. Contribution of different processes considered in Scope 3 to total carbon footprint - 4.
