Ecowhite®
A natural tanning process
Beamhouse accounts for nearly 70% of wastewater in leather production. So, the benefit in terms of sustainability is guaranteed when replacing the traditional synthesized chemicals associated with petroleum with a 100% NATURAL PRODUCT.
- Totally avoid the use of salt in the pickling process, significantly reducing the environmental impact
- Total absence of metals in the tanning and retanning process (metal free leather)
- Shrinkage Temperature (Tg) between 75”C and 80”C
Ecowhite® is a new way for produce leather from nature to nature
Specific chimical analysis on Ecowhite® leather samples were performed by accredited laboratory “Nuovi Servizi Ambientali S.r.l.” of Robassomero (TO, ltaly), in order to validate the technical and scientific assessment of the process and related products.
The content of heavy metals and free formaldehyde was analysed according to accredited methods on representative samples of Wet-white leather. Referring to the attached test reports, the results of the analysis are shown in the following tables.

Test Reports on Wet-white leather (digested leather samples) show traces of metals to be unrelevant, never intentionally used during wet process in drum. According to the most important analytical parameters, the technical assessment of the ECOWHITE® process and the composition of chemical products in use during the processing phases confirms:
- the compliance with the most stringent leather standards
- the eco-environmental relevance and the achievement of the principles and objectives of:
- Process efficiency
- Maximization in the use of renewable resources
- Save to use
- Eco-sustainability and compatibility during the full materiallife-cycle
