| Résumé : |
Despite all the efforts to develop an organic tanning process able to meet the same standards as the chrome tanning and wet-blue production (WB), no universal system has still been developed with the same performance and wide spectrum of applications as chrome tanned leathers.
Assuming that chrome tanning and wet-blue production will still be in use over the next few years, and bearing in mind that chrome shavings and other solid chrome containing wastes represent one of the major problems for disposal or recycling, Trumpler have been develop ng an innovative process designed to reprocess and reuse shavings (from wet-blue or wet-white) in the production of a novel range of green chemicals with a low carbon footprint for the retanning of leather.
Currently chrome shavings are disposed of in landfill or recycled in the production of leather board. Current methods of using chrome shavings include an economic cost to the tanner. The total quantity of chrome shavings produced will be strongly dependent on the kind of article and the process used in each tannery. |
