The Adon21 project was born in 2016 from Vesta Corporation’s need to
start thinking about leather according to completely new standards.

Leather as we know it today, uses as tanning agents, heavy metals (such as chrome, aluminum, titanium, zirconium), glutaraldehyde, phosphonium, or in a more classic way, vegetable tannins. The global technological evolution run at a frenetic level in every sector; every single minute in the world, is born a new idea to improve the conditions of human existence and by consequence the health of the planet.

It is unimaginable that leather should not follow the same technological development, since it is a product of natural origin:

it must be the first to witness what nature is.  The project starts with the primary objective of removing heavy metals from the tanning process, excluding glutaraldehyde or phosphonium, and excluding a classic vegetable tanning. In this regard, the study starts by introducing synthetic products that exclude the above-mentioned tanning processes.

Over the years, evolution has inexorably been highlighted, allowing the use of increasingly advanced methods and paving the way towards the goal of ADON21.

Adon21 leather differs diametrically from a classic leather in the chemical baggage it carries with it.

We are dealing with a Metal Free article that therefore meets the definition expressed in the UNI EN 15987 standard.

Why metal Free?

– The phenomena of human awareness to some heavy metals in direct contact with the skin are well known.

– The waste treatment of the artifact strongly restrict the release of heavy metals in the environment.*

Excluding the above-mentioned products from the process and introducing low-risk ones, the safety of the entire process obviously gets a huge boost upwards.

Almost 50% of the chemical products used in the Adon21 process are in a concentrated liquid form, which, excluding cutting aggregates, are of high quality.
They will be handled by an automated system, so that the number of containers used is limited and in so doing will be avoided that the operational staff handle chemical products although only poorly dangerous. Our aim is to reach 85% of liquid products in order to make the process even smarter and safer.

The entire process has been developed in order to improve its environmental impact.

Process temperatures have been reduced of 25-35%, this data indicates that, in wet phase working process and in part of finishing sector, we would have a lower consumption of combustible used for water heating, and a consequently lower greenhouse emissions.
From a mechanical working process point of view it would be required a lower electrical energy quantity to bring machineries to the appropriate temperature.
As we all know tanning processes employ remarkable water quantity, in contrast , Adon 21 process, which is in constant development, boasts a water saving of 15%, compared to chrome process.

Physical performances of Adon 21 product, in terms of tensile strength, tear resistance and grain crack, can be compared to those of chrome tannage (if you compare same article with same nature).
The fiber, which has a relevant density, manage to cope the mechanical stresses due to the traditional working processes. During the prototyping phase of new articles these can be molded on the basis of our customers additional requests.

The Adon21 study, in continuous evolution, aim to implement a new fellmonger
process in a sufficiently near future.

This sees the exclusion of the classic sulfides dedicated to hair removal and the canonical and harmful anti-wrinkles; making the process even safer and noticeably improving the quality of waste water.
The introduction of probiotic agents into the process makes all this possible, as a result the processing steps are even more Green.

The project also includes, although in an experimental phase, a revolutionary dyeing process that excludes from the process the classic “anilines”, which bring with them a good level of danger for the process user, replaced with state-of-theart pigments totally harmless, also in liquid form. The Adon21 process currently boasts of:
Return a Metal Free leather in accordance with the UNI EN 15987 standard; Water savings of almost 15%; Operating temperature reduction of 25-35% with consequent reduction of greenhouse gas emissions; Use of 50% of products in liquid form for greater operator safety and improve the quality of waste water by reducing the sulphate content.
