The finishes that characterize the product vary from the simpler and more traditional ones such as glossy, semi-gloss and matt to those related to seasonal development or to the individual customer that involve more complex and various types of finishes, such as paintings and shades handmade, embroidery, inserts and other particularities that can exploit atypical and therefore innovative technologies and skills for the tanning world and which represent the result of constant research beyond the company perimeter.
Zuma Pelli Pregiate deals exclusively with CITES certified fine leathers such as alligator, nyloticus and porosus crocodile, reticulatus and molurus python, lizard and ostrich. The Casadacqua brand instead follows exotic and reptile leathers of species that typically do not require CITES certification such as: ayers, karung, elaphe, vipers and mangrove monitor lizards.

protocol z.0

The z.0 protocol represents an innovative process for the tanning sector and was conceived and developed internally by Zuma Pelli Pregiate.
The research has produced a result that can be substantially defined as “eco-sustainable” guaranteeing, at the same time, all the characteristics of traditional processing.

The idea was born to create a product that responds to the sensitivity of our sector on environmental issues. This challenge is the result of the conviction that, as a company operating in the tanning sector, Zuma Pelli Pregiate must make a strong innovative contribution in terms of environmental protection. After investing time and resources in the search for a product that meets these expectations, the company has come to the definition of the process protocol z.0 with characteristics of stability, reliability, duration and applicable to all types of fine and non-precious fur.
The path required a great effort to overcome the difficulties faced in the various internal industrial processes to obtain a performing product like the one developed with traditional tanning.


Historically, the mineral tanning system has come a long way by improving in terms of health of workers and purification techniques, respecting increasingly stringent and safe regulations. The evolution in this sense is represented by metal-free conce but the real leap in quality in terms of real eco-sustainability at 360 ° is represented precisely by the z.0 protocol whose application, while requiring constant research, greater times of processing and costs, has as direct consequences the absence of: Biocides / Orthophenols / Formaldehyde / Potassium permanganate / Allergens and harmful / toxic substances for the environment and human beings; and the reduction of at least 50% of synthetic retanning chlorides and tannins.
Considering the substantial reduction in the presence of metals in the finished leather (presence much lower than the “standard” definition for “metal-free” leathers – uni en 15987: 2012 – therefore the concentration of tanning metals – cr, al, ti , zr, fe – must be less than or equal to 0.1%, i.e. less than 1000 mg / kg or ppm with respect to the total dry weight), the laboratory tests performed in the development phase of the protocol on the finished product produced results very encouraging. Furthermore, the absence of further metals was verified (in a concentration lower than the characteristic detection thresholds of the tests which are generally <0.5 ppm) in the list: Antimony / arsenic / barium / cadmium / cobalt / mercury / nickel / lead / selenium.
