Leather Research Department


The Leather Research Department is anchored in maintaining the European tradition of the leather and footwear industry, recognized as a world leader in ecology and sustainability and having a key role in the global market.
The thematic areas of research addressed in 2019 are aligned with the European objectives regarding the role of interface between the leather industry, agriculture and society, by:
   i) making smart materials to reduce environmental impact and increase competitiveness of the leather industry,
   ii) superior use of protein by-products in a circular economy, with neutral environmental impact, and
   iii) creating new methods of investigation and conservation of leather and parchment heritage objects, as a vector for the transmission of representative cultural messages over time.
Research results meet the demands of the industry, agriculture and cultural heritage regarding the development of ecological alternatives with neutral environmental impact, obtaining sustainable, smart materials that contribute to the protection of the environment, consumers and cultural values.
Regulations affecting the leather industry refer to pollution (REACH Regulation (1907/2006), Directive 96/61/EC on Integrated Pollution Prevention and Control), voluntary eco-labeling on carbon footprint and harmlessness of leather goods (OEKO-TEX®, LEATHER STANDARD) or certification of chemicals free of harmful compounds (øZHMC), which lead to increased competitiveness, involve continuous innovation of chemical materials, processes and high performance in the evaluation of potentially hazardous substances.

The areas of expertise of the Leather Research Department are structured within three research topics:
► Advanced materials, nanomaterials and smart technologies for the leather industry, with results in the application of new materials (organic and organo-metallic tanning agents from renewable resources, leather and fur free of chromium salts), nanomaterials (nanocomposites based on nano titanium dioxide, silicon dioxide, nano Ag, nano Cu, graphene oxide, with photocatalytic activity in the UV and visible domain and with antimicrobial and photocatalytic properties) and smart technologies (including unconventional technologies using gamma radiation, plasma, electrospraying) to obtain leather with biocidal, self-cleaning properties, with ecological impact on the environment and consumers.
► Biomaterials based on proteins and plant extracts for applications in industry, agriculture and other fields, with achievements on advanced technologies and additives for leather processing and for other applications: foliar fertilizers, growth stimulating agents, nutrition and treatment of plants and seeds, protein nanostructures with bioactive properties, vegetable tannins from alternative resources, protein and herbal auxiliaries for leather and fur processing.
► Study, characterization and diagnosis of heritage objects made of leather, parchment and wood, with results regarding the elaboration of the protocols to assess degradation stage, deterioration mechanisms, methods of prevention and conservation, development of software dedicated to environmental monitoring or the acquisition of data regarding behavior in hydrodynamic tests, approach of innovative cleaning and preservation techniques, development of new leather and parchment materials, and emulsifiers and preservation agents for heritage objects or for creative industries.

The department's expertise was leveraged through consulting services, technological transfer, technical assistance, dissemination and education activities for:
● evaluating new plant-based materials regarding tanning capacity, which underlies the design of new ecological materials;
● development of parchment for ecclesiastic use and for the creative industries;
● making leather for heritage bookbinding;
● development of products for maintenance of natural heritage leather;
● technological transfer for leather and footwear manufacturing;
● mentoring in European Project Semester (UPB).

Fig. 1. Graphic representation of the dynamics of institutional development and mobility projects for young researchers

Figure 1 shows that in 2019 the values of projects dedicated to institutional development (Nucleu, Complex Projects) and to training of young specialists (scholarships for mobility) were on the rise, as a result of participating in the project dedicated to institutional excellence. Also, there is a substantial increase in projects for awarding research results (233% more than in 2018), as a result of the completion of a large number of national and international projects. Although the number of projects increased in 2019, their value decreased by 22.5% due to the lack of national competitions, especially technology transfer projects, and to the lower value for international projects, which are in the final implementation stage.

The scientific activity carried out in 2019: The results of scientific activity carried out in 2019 materialized in: 20 articles published in ISI indexed journals with a cumulated impact factor of 54.148 (IF=2.7/article) 4 articles in international database indexed journals, 3 books, 142 citations in Web of Science, 34 scientific communications presented in international conferences, 10 patents and patent applications (9 national and 1 EPO) and 4 awards. The year 2019 was marked by an intense activity of training young researchers, including by participating in international training scholarships in renown research groups: Institut de Recherches sur la Catalyse et l'Environnement de Lyon, Paris, University of Zagreb, Institute for Biological Systems (ISB), CNR Research Area of Rome, Istituto Nazionale di Fisica Nucleare (INFN) - Laboratori Nazionali del Sud (LNS), Catania, University of Turin - Department of Chemistry, University of Pisa.
