Last 3 December the Italian Leather Research Institute (SSIP) organised a webinar to disseminate the intermediate results of the “Ri-Leather project: new development of products and technologies for the reduction of hazardous and polluting substances, the reuse and recycling of leather processing waste”.
Launched in autumn 2019, the project bears the signature of SSIP as a scientific partner and involves the chemical products company Real Color as leader, the Montebello tannery, the Corradi tannery and the Biodermol company specialising in enzymes. During the webinar the protagonists of the project reported the results achieved so far in the various areas of expertise. In particular, there has been talk of green technologies for sustainable hair removal and the enhancement of by-products of the tanning industry.
In fact, the work carried out by SSIP aims at introducing innovative chemical products and tanning processing processes – from the depilation/liming phase, to tanning and retanning – in order to reduce the environmental impact and introduce new eco-sustainable products on the market, aimed at improving creative productions.
Specifically, the objectives of the project are: the reduction of purification sludge and wastewater COD, through the introduction of a new enzymatic/oxidative hair removal system with hair “recovery”; the consistent reduction of polluting and dangerous substances such as sulphides in the hair removal treatment; the reuse of the intact hair and free of dangerous substances for the production of padding and insulating panels and technical fabrics; the reuse and recycling of tanned leather residues and their characterisation and enhancement in terms of biodegradability of crust leather; COD reduction in the retanning waste process.
During the webinar have spoken: Edoardo Imperiale (General Director of SSIP), Alessandro Rama (Responsible for coordination of investigations and FESR-AVEPA control activities), Marco Nogarole (Technical Manager of the Arzignano District of SSIP), Davide Frascaro (Responsible for R&D of Real Color), Francesco Corradi (Head of Research and Development of Conceria Corradi), Mauro Baruchelli (CEO of Biodermol) and Viola Dalle Mese (Marketing Manager of Conceria Montebello).
