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.

Carbon footprint of a tanning company / Eylem Kiliç in LEATHER INTERNATIONAL, Vol. 217, N° 4863 (08/2016)  

[article]  inLEATHER INTERNATIONAL > Vol. 217, N° 4863 (08/2016) . - p. 20-23 Titre : Carbon footprint of a tanning company Type de document : texte imprimé Auteurs : Eylem Kiliç, Auteur ; Rita Puig, Auteur ; Gökhan Zengin, Auteur ; Arife Candas Adigüzel Zengin, Auteur Année de publication : 2016 Article en page(s) : p. 20-23 Langues : Anglais (eng) Catégories : Bilan des émissions de gaz à effets de serre Cuirs et peaux -- Industrie -- Aspect de l'environnement Cuirs et peaux -- Industrie -- Turquie Tannage -- Aspect de l'environnement Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Over the past few decades, climate change has evolved into an issue of global concern. 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. Relative contribution of greenhouse gas emissions from different processes to total carbon footprint of Turkish tannery En ligne : https://drive.google.com/file/d/1W2yVVNtaYZLalZo0FGHQnhkDypgOWphj/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=26904 [article]

Deliming with weak acid-effects on leather quality and effluent / S. M. Colak in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 92, N° 3 (05-06/2008)

Eaux usées -- Analyse Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Effluent which has a high ammonium content is produced as a result of traditional deliming operation using ammonium salts. Ammonia is converted into nitrate by the nitrogen cycle in nature and ammonium salts discharged into natural water sources have toxic effects on living organisms.In this research weak acids were used to delime in studies on sheep skins to reduce the ammonium load that originates from deliming. Beside the deliming effect of acids, the N content of the resulting discharge water was determined and the effect of these methods on the quality of the leather was studied. The data obtained from the study were compared with the traditional deliming methods and standards.
