Few materials have characteristics of recycling so close to the original as those of the leather. The manufacturing process of the leather is highly polluting because it uses chemicals. The tanning with substances based on minerals (alum) is then left with the use of salts of chromium, iron or zirconium.
Recently mixed systems for tanning also have grown: the leather already tanned with chrome is again processed with vegetable to improve its appearance and physical properties. To implement, however, more environmentally sustainable behave should move towards the regenerated leather, obtained from cuttings of the vegetable and worked leather with oil and natural latex as a binder.
After obtaining an homogeneous mix of material through the addition of water, the process continues in a similar manner as the production of paper. It follows a process of treatment with water mixed with other substance, especially fats and coloring agents, completely natural.
The compost is spread over large counters for drying and it is pressed and then treated so that they get soft. The result is produced in large and continuous sheet with different quality, softness and thicknesses, for the most varied products. The strengths of recycled leather are the guarantee of its long duration (10 years after the material deteriorates only by 10%), the color fastness to the light and to the friction and the smoothness of the surface.
For example, the line C-Re-ate designed by R’dF Design Factory has a number of items for the office in recycled leather from the German company Salamander.
The regenerated leather is made from 65% of discarded leather tanned with vegetable matter, for 18% of natural latex (rubber extracted from plants) for the 10% water, 5% from natural fats and the 2% natural coloring agents and salts.
