The main environmental regulations concerning Europe’s tanning industry are the EU Integrated Pollution Prevention and Control (IPPC) Directive (96/61/EC), the Water Framework Directive (2000/60/EC) and the REACH Regulation. In order to maintain competitiveness in the global market place, European leather producers must exploit raw materials more efficiently and eliminate from industrial processes the negative impacts of waste materials (hides and skins).

The raw materials required for tannery processes generate waste that currently has a significant negative environmental and economic impact. However, tannery by-products could be reused/recycled or converted into higher value secondary raw materials for other industries and the agricultural sector.

Accordingly, EU tanners are adjusting and modernising their production methods, with investments in environmental protection, waste reduction, recycling and the recuperation of secondary raw materials. The impact of environmental regulation on the leather tanning industry is considerable. The industry estimates that environmental protection costs amount to 5% of all operational costs. Moreover, in accordance with the river basin management plans of the Water Framework Directive, tanning companies must take into account measures to reduce water pollution and adopt concrete actions to maintain the good ecological status of watercourses.

PROJECT GOALS:

The PODEBA project aims at demonstrating the use of an innovative material, a recycled waste (poultry dejection) for the bating phase in the leather tanning process, for the production of new leather products with a significantly higher eco-sustainability profile.

The environmental impact of the project is evidenced through the following means:
• Recycling and use in an innovative application of a waste, poultry dejection, characterized by high environmental problems of management and disposal.
• Application of an innovative treatment able to deodorize the poultry dejection.
• Use of recycled waste instead of industrial products with high saving of economical costs and energy and water consumption.
• Drastic reduction of the high environmental impact of tannery wastewater by using a natural product instead of traditional industrial products in the bating phase.
• Production of leather products with biological, eco-friendly properties for well.-being, health, product customization, clothing and smart furnishing.
The PODEBA project will demonstrate the eco-sustainability of using poultry manure for the ‘bating phase’ of leather tanning – a process whereby the hides for high quality leathers are treated with enzymes to soften them.The expected environmental benefits are as follows:

1. Recycling and reuse – an innovative application of a waste (poultry manure) normally associated with high environmental problems in management and disposal;
2. Significant reductions in the negative environmental impacts from tannery wastewater by using a natural product instead of traditional chemical products in the ‘bating’ process;
3. The application of an innovative treatment able to deodorise the poultry manure;
4. Use of recycled natural waste instead of industrial chemical products, with savings in costs and energy and water consumption;
5. The application of innovative formulations of polyfunctional substrates for regulation purposes with active principles that enable controlled release; and
6. Production of high-end (fashion) leather products with anti-microbial, self-cleaning, biological, eco-friendly properties.
Expected results:

1. The application of an innovative deodorisation technique for the poultry manure with the production of 2.4 Mg of laying hen manure and the reduction of ammonia emissions (50%) in final product compared with those from initial wet laying hen manure;
2. A reduction in the costs of the bating phase by re-using a waste product instead of industrial chemical products;
3. A reduction in the negative environmental impact of the tanning process by using a natural product (e.g. reduction of sulphur compound emissions of c. 50% at laboratory level);
4. Lower water and energy costs;
5. Fewer negative environmental impacts from the management of the poultry manure;
6. A reduction of pollutants in wastewater; and
7. The production of footwear and furniture using the innovative bating technique (i.e. 100 pairs of shoes and 10-15 upholstery products such as sofas or chairs).
