This has become a very topical issue for the tannery cluster of Arzignano, particularly because the wastewater treatment plant has been given a deadline for the reduction of these substances in their released effluent.
For this reason, many important people at the wastewater treatment plant, such as Ing Orsetti and Ing Refosco, as well as the mayor of Arzignano, Dr Stefano Fracasso, joined the workshop. The presentations of Dr Umberto Sammarco (a local expert in this field), Antoine Lenglart and Mariano Baldisserotto provided the participants with an extensive update on the global status of research and technology.
Afterwards the latest results gained by TFL in this crucial field of research were presented: the TFL Hair Save System and the ammonia-free deliming to name two. In addition they introduced the new non-swelling pickle acid Sellatan PA, that can replace all pickle acids used in the tanning process featuring an important reduction of chloride and sulfate in the released tanning float. Furthermore, it enables an improved chrome fixation thus allowing a reduced offer.
After giving the main guidelines for the industrial application of their specialties and the illustration of the first results, an open discussion followed that went on during the final buffet.
Commencing January, all the tanneries will have to conform to these new parameters. The requirement for eco-friendly solutions attracted about 70 people who were very enthusiastic to participate to the event conducted by TFL.
