Project for recovery and reuse of industrial waters and trivalent chromium generated by tannery waste processing (RIWAC)
Start date: Oct 1, 2005, End date: Sep 30, 2008,
Background
In Europe, wastewater from tanneries is currently discharged directly to wastewater treatment plants. However, some components in the waste could be recovered for destruction or recycling, in particular ammonia, calcium sulphate and chrome. In Italy, most of the chrome-containing waste is used in agriculture as organic fertiliser, but no chrome ...

Saving of forest exploitation for obtaining of tanning extracts through valorisation of wine waste (GRAPE TANNINS)
Start date: Sep 1, 2004, End date: Dec 31, 2007,
Background
Deforestation is a major problem that should be restricted wherever possible. The use of renewable sources of tannin can make a contribution to reducing deforestation. Tree species such as quebracho and chestnut are currently felled to provide tannin for the leather industry.
Alternative sources of tannin exist, chiefly from a by-product (grap ...

Aqueous degreasing of fatty sheepskins through the replacement of ethoxylated nonylphenol by biodegradable ethoxylated alcohols and further recycling (DEGREASING)
Start date: Sep 30, 2002, End date: Mar 31, 2005,
Background
Degreasing is one of several steps in the hide tanning process. The amount of natural fat contained in sheepskins is significant and can have an effect on the process. Therefore, the fat has to be removed to avoid stains and dyeing irregularities. However, sheepskin degreasing results in a high degree of pollution in the tannery wastewater and, ...
