Influence of humidity and temperature on leather [premium content]
The effect of change in the dimensional stability of leather can be significant when subjected to changes in temperature and relative humidity. The results of the determination of these dimensional changes can vary from one laboratory to another for the same sample of leather. In order to limit possible errors, the causes attributable to the testing procedure were investigated within the framework of inter-laboratory trials.

Biological nitrogen elimination with simultaneous biological sulfide o... [premium content]
Cleaning tannery wastewater has never been a trivial task, especially for those leather manufacturers who directly discharge into surface waters. Because of the dramatic
savings in water consumption that have been achieved over recent decades by Bader, the wastewater is usually highly concentrated, especially with nitrogen compounds. However, a targeted denitrification process combined with simultaneous sulfide oxidation allows the company to eliminate the nitrogen compounds from the wastewater by at least 70% and at a reasonable cost.
