Results

The project has the following technical goals:

  • Demonstration of use of innovative formulations free from toxic products deriving from leather tanning.
  • Substitution of chlorinated with eco-sustainable natural products in the defatting process
  • Optimization and application of new tanning formulations specific to defatting phase, containing products derived from natural raw materials such as glucosides, bio-masses, husk, vegetable oils, highly absorbed by leather.
  • Study and application of intelligent and ecological products: leather treated with formulations allowing controlled release of natural biological active principles or perfumes.

The main project ECODEFATTING results quantification consist in:

  • The substitution (100%) of raw materials of petrochemical origin with others based on renewable sources implies a substantial change in the project’s environmental sustainability.
  • The potential problems connected with bio-accumulation are ruled out by the foreseen elimination (100%) of the presence of chlorinated molecules from the process. This, as well as the elimination (100%) of the chlorinated functional group, will increase the project’s sustainability.
  • As for biodegradability, the use of raw materials derived from natural sources does not necessarily imply an increased biodegradability. Nevertheless, since bio-accumulation is by definition connected with non-biodegradability, the elimination or drastic reduction of bio-accumulation will involve an increase (100%) in the biodegradability profiles of the molecules used.
  • Increased (50%) penetration of defatting products into derma, resulting in better performances of the finished product.
  • Defatting exhaustion, i.e. less (30%) product consumption.
  • Less (20%) pollutants in bath waste-waters.
  • Reduction (20%) of water consumption during the tanning process.
  • Reduction (20%) of polluting load in tannery waste water.
  • Toxicity reduction of high chlorine in the tanning cycle (100%).
  • Reduction of tannage waste (reduction of the waste management cost by 33%).
  • Reduction of energy consumption (20%).
