Reducing chemical consumption and waste water COD loadings by recycling in conjunction with membrane filtration / K. Hellinger in WORLD LEATHER, Vol. 14, N° 7 (11/2001)  

[article]  inWORLD LEATHER > Vol. 14, N° 7 (11/2001) . - p. 37-41 Titre : Reducing chemical consumption and waste water COD loadings by recycling in conjunction with membrane filtration Type de document : texte imprimé Auteurs : K.

However, for the production of very soft chrome-free leathers higher amounts of fatliquor, vegetable and synthetic tans are required. These quantities are greater than needed for leathers made from wet blue, and exceed the amounts which can be bound by the leather. These non-bound materials therefore remain in the process liquors and give rise to high COD in the effluent. A simple reduction in the offer of fats and retans to reduce this wastage does not solve the problem, as it leads to a deterioration of handle, softness and fullness. Wider introduction of leathers based on wet white therefore results in higher chemical costs, and increased effluent loadings and charges.

Total dissolved solids management (TDS) in tanneries / A. Sahasranaman in WORLD LEATHER, Vol. 14, N° 7 (11/2001)

In particular, this problem is associated with common salt used in raw material preservation and, although there are other alternative ways of cure, often these are not appropriate. There is no single way of combating the TDS problem, but a combination of actions to reduce the salt input, reuse or recycling of floats before treatment of segregated waste waters are of significant importance.

Cutting costs through reducing waste packaging and packaging waste / Stuart Ballinger in WORLD LEATHER, Vol. 14, N° 7 (11/2001)  

[article]  inWORLD LEATHER > Vol. 14, N° 7 (11/2001) . - p. 49-51 Titre : Cutting costs through reducing waste packaging and packaging waste Type de document : texte imprimé Auteurs : Stuart Ballinger, Auteur Année de publication : 2001 Article en page(s) : p. 49-51 Langues : Anglais (eng) Catégories : Coût -- Contrôle Déchets -- Elimination Déchets -- Réduction Déchets d'emballage Matériaux d'emballage -- Recyclage Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Packaging is a term used to describe any material used for the containment, protection, handling, delivery and presentation of goods (from raw materials to processed goods) from the producer to the end-user or consumer. The word 'packaging' is used to describe materials that contain or protect goods received, are used with in-house transport of part processed goods and waste, final delivery of processed products, and identification. Cost savings, increasing environmental awareness, and recent European legislation is proving key driver for many companies to address packaging use, reuse and waste. Even if a compagny is not obligated, it will both affect and be affected by others in a supply chain. Reducing the quantities of packaging and cutting associated costs are therefore issues that are applicable to all companies. In the leather industry, the problems associated with packaging are greater with goods received with packaging are greater with goods received and in-house management, than in the area of dispatch. Packaging waste is also part of dispatch. Packaging waste is also part of the larger waste generation problem, but many options are open to reduce the effects of redundant packaging and save maney. When looking for savings ; work through the stages of the waste hierarchy : elimination ; reduction ; reuse ; recycling ; and finally, disposal.

Managing health and safety matters in tanneries / Richard Bowden in WORLD LEATHER, Vol. 14, N° 7 (11/2001)  

[article]  inWORLD LEATHER > Vol. 14, N° 7 (11/2001) . - p. 52-55 Titre : Managing health and safety matters in tanneries Type de document : texte imprimé Auteurs : Richard Bowden, Auteur Année de publication : 2001 Article en page(s) : p. 52-55 Langues : Anglais (eng) Catégories : Accidents -- Prévention Cuirs et peaux -- Industrie Gestion du risque -- Mesures de sécurité Sécurité du travail Travailleurs -- Protection Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Most tanneries that I have visited over the years have one thing in common. All the safety hardware is in place such as the machine guards, separate routes for pedistrans and workplace transport, computer controls, signage, etc., but the majority fall down on the software - the managment of health and safety. Take, for example, the case of a tannery using solvents where smoking was prohibited and where the supervisor was seen lighting up a cigarette directly under a No Smocking sign. What message does this give the workforce? Health and safety doesn't matter! This type of attitude is seen all over the globe to a lesser greater extent. Also heard regulary is the statement that "We don't have accidents" or "We haven't had an accident in years". But what is an accident? An accident may be defined as : An unplanned, uncontrolled event or exposure that has led to, or has the potential for, injury, damage or some other loss. This includes not only injuries, but incidents where damage occurs and those where there is no actual harm done, but where there could be in future. This latter is called a near miss and is good indicator of a forthcoming event. Note de contenu : - FAILURES IN MANAGEMENT = ACCIDENTS - MANAGEMENT BEGINS WITH THE MANAGING DIRECTOR - SETTING THE SCENE : The policy statement - The organisation - The arrangements - IMPLEMENTING THE MANAGEMENT SYSTEM : Indentifying shortcomings and setting objectives - Targeting key objectives - MAINTAINING THE MANAGEMENT SYSTEM : Reinforcing the savety culture - Audit and review for improvement En ligne : https://drive.google.com/file/d/1nRmUjmIRNF5qHFxJ5cI8I8wyso5xsmY4/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=32188 [article]
