[article]
Titre : Environmental & safety issues - clean technology and environmental auditing Type de document : texte imprimé Auteurs : K. T. W. Alexander, Auteur ; D. R. Corning, Auteur ; N. J. Cory, Auteur ; V. J. Donohue, Auteur ; R. L. Sykes, Auteur Année de publication : 1992 Article en page(s) : p. 17-23 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather production yields emissions to water, land and air - all of which are increasingly subjected to legislative control. Furthermore, safety for employees within the work place has to ensured.
Compliance with this increasingly complex regulatory system precludes single objective approaches. Environmental auditing is a systematised approach to identifying the problems within a particular sector or production unit.
To ensure that the leather industry can effectively reduce its environmental impact, BLC is co-ordinating two international projects to provide reliable information on the real, as distinct from claimed, status of clean technologies applicable to this sector.
Monitoring of the work place and its emissions makes analytical demands beyond the scope of traditional tannery laboratories and recent developments will be reported.En ligne : https://drive.google.com/file/d/1YDQawlXsLkT4uOQdj7KGlpXsTmYHa83Y/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8643

PesticidesUn pesticide est une substance répandue sur une culture pour lutter contre des organismes considérés comme nuisibles. C'est un terme générique qui rassemble les insecticides, les fongicides, les herbicides, les parasiticides.Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this report insecticides, which have been shown to protect dried skins from attack by dermestes maculatus, and most of which are classed as safe for use in stored food grains FAO, have been evaluated for persistence during tannery processing.
In these trials key parameters are considered to be the quantity of insecticide remaining in the spent process liquors (including suspended solids) and the amount remaining in the pickled pelt. These results are summarised in tabular form below. The amounts of active insecticide on the skins when put into work were not constant and are not to be taken into account when comparing concentrations in the effluent.En ligne : https://drive.google.com/file/d/1bA0hP1WZKLQb1ivFp425aup4XVb94IK0/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8557

TannageIndex. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Public sewage treatment authorities are often bath to accept tannery effluents because they are apprehensive either about the effects of specific components, e.g. heavy metals and sulphides on their processes, or of the high COD to BOD ratios which have been cited as indicating non-biodegradability. Real resistance to treatability is even more relevant to onsite biological treatment by the tannery.
The work described below was undertaken to investigate both of these aspects. Laboratory trials were carried out, using various techniques, to examine the inherent treatability of a number of tanning materials, dyestuffs and other chemicals widely used in tannery processes. Later, one of the techniques was employed in a study of the treatment of a mixed effluent, the work subsequently being extended to pilot plant operation in a tannery.Note de contenu : - EXPERIMENTAL TECHNIQUES : Laboratory scale activated sludge plants (ASP) - Respirometry

Titre : The effect of soil-chromium III on the growth and chromium absorption of various plants Type de document : texte imprimé Auteurs : R. L. Sykes, Auteur ; D. R. Corning, Auteur ; N. J. Earl, Auteur Année de publication : 1981 Article en page(s) : p. 102-125 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Greenhouse trials were carried out to grow crops in soil to which chromium III in various forms had been added. The dressings included tannery sludges from both bovine and sheepskin production, a proprietary fertilizer manufactured from chrome leather scrzp, a sewage-plant sludge containing appreciable amounts of Cr III, and precipitated Cr III hydroxide. The progress of the various crops was minotored and their fruit, leaves, roots, etc., were analysed for Cr III, as applicable. Although some of the mixtures were beneficial to plant growth, these effects could not be attributed to the presence of Cr III, but the results fully confirmed the nontoxicity of Cr III, at least at a level of 500 mg/kg in the soil. The concentration of Cr III in the soil had a negligible effect on the uptake of Cr III by the edible portions of the crops.
