Leather manufacturing is classified as water, energy and waste intensive by the Industrial Emissions Directive (2010/75/EU). Tannery effluents, if not properly treated, cause significant damage to soil and
water bodies. Over 85% of world leather production involves the traditional chrome tanning process (TCTP). The use of chrome (Cr) in the industrial processing of animal hides poses serious environmental
and health problems due to the use of hazardous chemicals, the production of solid/liquid waste and air emissions.
LIFE GOAST aims at demonstrating the benefits of a new tanning technology on a semi-industrial scale; the project started on July 2017 and is an ongoing investigation, and involves the competences of three direct actors in the leather industry such as GSC Group spa as chemical supplier, Conceria Pasubio as tannery and Mediochiampo as waste-water treatment agency, in conjunction with the expertise of Università di Venezia, thus forming together a model of leather industry. The technical feasibility of LIFE GOAST implementation, as well as its social and economic impact, have been monitored and compared with the TCTP in order to demonstrate the reduced environmental impacts of the new process, while producing comparable or better quality leather.
The LIFE GOAST team demonstrated that it was possible to treat collagen with the GOAST technology to give stabilised collagen to be used in the leather industry. A series of leather swatches were realised in accordance with the new protocol in order to obtain preliminary information on chemical oxygen demand COD of the effluents and technical feasibility of the process. The results were remarkable: COD values were lower than TCTP and it was possible to obtain soft and firm grain leather despite a shrinkage temperature lower than chromium process. However, these preliminary results allowed to process bigger pieces of leather (quarter, half and entire) to demonstrate that the technology was reproducible and in line with the small trials. The investigation is still ongoing and the team is fully committed to focus on the objectives of the project.
