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.

Comparison of the sustainability of the vegetable, wet-white and chromium tanning processes through the life cycle analysis / Anna Bacardit in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CXV, N° 3 (03/2020)

Tannage Résumé : Public concerns about the quality of life of human beings as well as the quality of natural environments and ecosystems have led to the increasing importance of sustainability for governments and for all industries, including the leather industry. In this context, more "ecological" leather goods are being demanded. It should be noted that this concept is often used without a scientific study to support it. This concept of sustainable or ecological product in the field of leather goods, are mainly associated with chrome-free tanneries (that is vegetable and wet-white), but this association should be backed up or dismissed by scientific evidence. A complete scientific study is required, which takes into account the different stages of leather production, including also the treatment of water and by-products, analyzing in a scientific and systematic way the environmental impact of each of these tanning processes. This study focuses on the life cycle analysis of the three basic tanning processes: chrome, vegetable and wet-white leather production. It will focus on European manufacturing to have reliable data and reduce uncertainty. In the tanning stage, the process with the greatest impact is the vegetable one, to highlight its high impact on global warming at 100 years (GWP100). This result is due to the energy necessary for the production of mimosa and quebracho in addition to the energy for the processing of the leather in the drums. Wet white tanning with glutaraldehyde has lowest environmental results than vegetable tanning. The chrome tanning process (wet blue) also stands out for its reduced environmental impact. Subsequently, to have a global view of the entire production, the LCA of the post-tanning stages must be performed to evaluate the impact of each of the systems studied.

Industrial ecology as a planning approach for a sustainable tanning industrial estate / Rita Puig in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 92, N° 6 (11-12/2008)

Tannage Résumé : This paper analyses the relocation, following Industrial Ecology principles, of tanneries from Igualada, Spain to a new sustainable industrial estate. The tanning industry in Igualada has been located in the same river basin for more than 100 years. During the last decade, the city has been growing very fast and it is now beginning to force the industry to move to the outskirts. Environmental, social and economic aspects were analysed to assess the feasibility of the proposed move. Results clearly show that relocating the tanneries to a new industrial estate is absolutely necessary for these companies to achieve sustainability. This move is economically feasible, it will have important environmental benefits (compared to the present situation) and is agreed upon by all involved. However, a very important challenge was detected: there is no agreement on where to locate the new industrial estate. The current proposal made by Catalan authorities lacks the unanimous agreement of all involved. To solve this problem meetings among interested parties will soon take place. Otherwise, the future of this important cluster in Igualada is uncertain. This work helped the tanneries of the industrial cluster in Igualada, and could also help other similar clusters, e.g. to analyse the sustainability of a proposed move and to plan new sustainable industrial areas.
