The project, that will have a duration of 24 months, aim to the industrialization of a new technology, demonstrated trough another Life project closed positively in 2008 by the same company SICA S.p.A., leader in Italy in the sector, for the controlled micro-dressing of the leather that allow water, raw material and energy savings and that use natural dyes.

The project results very interesting because involves a high environmental impact sector and because it contributes sensibly to the technological advancement of the whole tanning sector in the environmental way. The new process enable the laying of the pigment only on the surface to be treated, using only the necessary quantity of colour and water, through optical and electronic controls of the whole system.

On the contrary, at the state of art leathers are treated in closed cabins in which the atmosphere, full of coloured micro-droplet, transfers the pigment on the surface, with high waste of solvents, water and raw material of over 80%.
Important reduction of 95% of polluting substances, as finishing chemicals and V.O.C., and of 98% of sludge from wastewater treatments

Use of natural dyes instead of the solvent based ones;
Reduction of energy and water consumption (-75% and -95%);
Obtaining a product equal to the traditional one but preferred by the market for its environmental characteristics.
Use of natural dyes instead of the traditional polluting ones, reduction the use of V.O.C., minimise energy and water consumption and waste production. Type of solution:new product (water based dyes), new process (in-line spray guns)

We are sorry. There is currently no information available in this section.
