Project Objective:
KER_COL_CE project is in line with the latest European strategies related to circular economy through proposed objective for prevention (PRODUCT DESIGN), reduction and recovery (WASTE MANAGEMENT) of leather industry waste in the frame of an eco-design for protein waste reintegration in economical circuit.
The project objective is to release at least two materials based on renewable resources for leather processing in the frame of circular concept of economy. The new products will allow to replace or reduce petroleum based chemicals (synthans, aldehydes, dyestuffs) or pollutant chemicals (chromium, ammonium salts).
Scheduled results:
- Transfer of laboratory scale technology for new composites based on collagen and keratin additives to pilot level
- Elaboration of new technologies for leather processing by using biobased products as alternatives to petroleum based chemicals in deliming, pe- tanning, tanning or retanning stages
- Test lots of different extracts with low and high molecular weights will be formulated in stable composites with reactivity for untanned or tanned collagen
- Development of new biobased material prototypes and ecological leather prototypes in the frame of a new circular technology for leather industry
- Evaluation of new biobased materials and leather prototypes
- Evaluation of a new circular process for leather industry in terms of economical and ecological impact
- Common patent applications and dissemination papers will be released by the consortium of three partners from Turkey (KAZLIÇEŞME) and Romania (SC TARO Comimpex SRL, Leather and Footwear Research Institute-ICPI).
After the completion of the project new biobased materials will be produced by the project coordinator, KAZLIÇEŞME (Turkey) and new circular technology for ecological leather processing will be integrated in the production of SC TARO Comimpex SRL (Romania).

The project aim is the revalue of an olive mill waste, the Wet Olive Pomace (WOP), for its reuse in the tanning sector. The project outcomes will generate an ecoefficiency improvement by reducing the environmental impact in two ways: Reusing problematic waste (WOP) and avoiding the use of chemicals in tanning formulations.
Specific Objectives of the project will follow different target actions as it is described as follows:
1. Development of new tanning processes, reducing petroleumbased re-tanning agents (aldehydes, naphthalenesulfonic, phenolic syntans and chromium salts) and commercial extracts (mimosa, quebracho or chesnut) used in the production of wetwhite, chrome and vegetabletanned leather obtained from nonrenewable resources, by using the new sustainable tannin.
- Application of the extract of olive residues (WOP) as a retanning agent of chrome leather (wet-blue) leather.
2. Validate new advanced WOP extract which will transfer value added features to the leather, due to its antioxidant capability provided by their phenolic compounds composition (avoiding Cr(VI) generation in chrome tanned leather) and its antibacterial properties. Antibacterial function of the WOP extract will be validated as an inherent property to highlight.
3. Setting up new production lines of OLIPO ecoleather, fulfilling the expected technical parameters, strict environmental requirements and quality certifications of high quality leather manufacturers. A production of 5.000 m2 of ecoleather for trade exhibitions will be made in cooperation with project partners, after the project completion, being the companies capable to cover the needs of its customers and creating prototypes to show in the most relevant leather fairs.
4. Obtain a sustainable and cost effective solution for the revalorization of byproducts from olive mills and olive oil extraction industry, aiming to recover highadded value tannins from twophase oil pomace waste (WOP).
