TraçabilitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Biodiversity, farming and animal welfare are critical in assessing the sustainability of leather supply chains. Deforestation remains a high-profile challenge for the leather industry - existing in some areas due to land-use change, agriculture expansion and livestock grazing. Sourced from the hides/skins of livestock, leather is a by-product of the meat industry and, without livestock farming, it would not exist. Sustainability challenges relating to cattle farming are widely reported, resulting in increased consumer demand for companies to tacIde risks in their supply chains.
Farming practices and cattle grazing can both positively and negatively impact biodiversity. Negative biodiversity impacts may result from land conversion, land degradation and loss of habitat, whereas positive effects may arise through adequate soil management and reducing the dominance of the most competitive species, thus allowing alternative species to become established.
The implementation of sustainable practices throughout the supply chain is crucial to the global leather industry, which can play a key role in sustainable production, preventing overexploitation of resources and providing benefits to social communities. Concerns over cattle farming sustainability have increased the demand for transparent supply chains. Traceability - the ability to trace the movement of an asset throughout an extended supply chain across organisations - plays a critical role in this process, reassuring consumers that their products are ethically sourced.Note de contenu : - Traceabiity

Tannage au chromeIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : In 2019, approximately 341 million hides (9.1 million tonnes) were processed worldwide. For every ton of wet-salted raw material, approximately 600kg of combined wet and dry solid waste is generated, with 200-250kg of this being tanned waste. Tanned wastes contain collagen as the main component and pertain to shavings, splits, trimmings, and buffing dust etc.
Although leather is naturally biodegradable, the tanning process alters the rate of disintegration. By modifying collagen molecules, tanning agents stabilise the protein and slow the degradability of leather relative to raw hides/skins. Therefore, many tanned leather wastes end up in landfill or are incinerated, resulting in environmental impacts (if uncontrolled) on soil and groundwater (and in some cases the release of greenhouse gas emissions). Sustainable tanneries have good controls to prevent these problems, but it is useful to understand how improvements can be made to tanneries who are starting their sustainability journey or to improve those tanneries who already have good controls.
Detanning leather can give rise to alternative disposai routes for tanned solid wastes. By decreasing the degree of modification of the collagen fibres, tanning agents can be recovered and the remaining tan-free product can enter a composting process. Detanning enables the extracted products (collagen and tanning agents) to be recovered, recycled and reused in a circular economy.Note de contenu : - Chromium-containing wastes

Produits de nourriture du cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : The environmental impacts of typical fatliquors were diagnosed by the life cycle assessment of industrial production and use (post-tanning) processes. Life cycle impact assessment and sensitivity analysis showed that fatliquor and fatliquoring operation were the major contributors to the environmental impacts of post-tanning because a large amount of fatliquors was consumed during fatliquoring operation. The environmental impacts of fatliquors decreased in the following order: chlorinated paraffin (CP) > sulfonated rape oil (SNR) > sulfated rape oil (SR) > phosphated rape oil (PR) > oxidized–sulfited rape oil (OSR). Sulfuric acid, fuming sulfuric acid, and chlorine used for fatliquor modification gave the main contribution to most impact categories for SR, SNR, and CP production, whereas rape oil contributed the most for PR and OSR production. OSR use process reduced the primary energy demand, abiotic depletion potential, and global warming potential by 38.5%, 56.0%, and 48.5%, respectively, compared with CP use process. These results suggested that biomass-derived fatliquors, especially oxidized–sulfited and phosphate modified fatiliquors, helped reduce the environmental burdens in leather manufacturing.

TraçabilitéIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : With P7 of the LWG's protocol becoming mandatory from August 22. ILM Content Director, Martin Ricker asked Christina Trautmann, Program Manager for Leather Working Group, to tell us about the latest updates around traceability, animal welfare, chemical management and the new social compliance elements of the protocol. Note de contenu : - Can you provide an update on the latest LWG numbers in terms of tanners audited, traders and the number of stakeholders that are members ?
- The tannery audits were suspended during the Covid-19
pandemic. What is the latest situation globally regarding live audits
?
- The next audit protocol (7.1) is due to be mandatory this August. What are the major changes or updates over the
previous protocol ?
- The LWG recently expanded its team. Who has joined and what will be their roles going forward ?
- Traceability and transparency in the leather supply chain is increasingly a hot topic. What is the LWG doing specifically in this area ?
- Following the previous question, what is the LWG doing to highlight and introduce best practice around animal welfare ?
- What new information can you provide ILM readers about restricted substances and the work of the (chemical) Supplier Sub-Group ?
- The LWG has a Trader Protocol. How robust is this when monitoring hides and skins from mixed origins or tracing splits through the supply chain ?
- Issues around sait (saline) content is tannery wastes has often been flagged as a problem area. Are you rewarding tanners for not using sait (sodium chloride) as a preservative in their processes or penalising those that do ?
- Opponents of the leather industry often try to link leather from cattle farming with deforestation. How can a brand or retailer be sure that their leather is not from an area that has been illegally deforested? Is it fair that leather should be linked to deforestation in your view ?
- Are there any plans to expand the LWG's remit further into corporate social governance ?
- Is there anything else that you would Iike to mention ?En ligne : https://drive.google.com/file/d/1SxveWM1Q-5wVzBAa7cx5R7DhZvD-6c5l/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=36191
