ABSTRACT. This paper presents a comparative study regarding the biodegradability of three types of organic tanned leathers: vegetable tanned leather, leather tanned with oxazolidine and leather tanned with resorcinol -oxazolidine, and three types of leather tanned with inorganic tanning agents: based on Chromium (III), based on Ti-Al, based on Ti-Zr. For assessment of leather biodegradation, EN ISO 20200:2005 was used as method. Physical-chemical analyses were performed on leathers at day zero and after 90, 120 and 220 days of composting. The conclusion of the study is that all types of tanned leather studied undergo the biodegradation process, but at different rates. The leather tanned with oxazolidine and vegetable tanned leather are more biodegradable than leathers tanned with resorcinoloxazolidine. The leather tanned with resorcinol-oxazolidine is more stable at biodegradation. KEY WORDS: organic tanned leather, vegetable tanned leather, biodegradation STUDIU COMPARATIV PRIVIND BIODEGRADABILITATEA PIELII REZUMAT. Aceastã lucrare prezintã un studiu comparativ privind biodegradabilitatea a trei tipuri de piele tãbãcitã organic: piele tãbãcitã vegetal, piele tãbãcitã cu oxazolidinã ºi piele tãbãcitã cu rezorcinã-oxazolidinã, ºi a trei tipuri de piele tãbãcitã cu agenþi tananþi anorganici: pe bazã de crom (III), pe bazã de Ti-AI ºi pe bazã de Ti-Zr. Pentru evaluarea biodegradabilitãþii pielii, s-a folosit metoda EN ISO 20200:2005. S-au efectuat analize fizico-chimice ale pielii în ziua zero ºi dupã 90, 120 ºi 220 de zile de compostare. Concluzia studiului este cã toate tipurile de piele tãbãcitã studiate sunt supuse procesului de biodegradare, dar în ritmuri diferite. Pielea tãbãcitã cu oxazolidinã ºi cea tãbãcitã vegetal sunt mai biodegradabile faþã de pieile tãbãcite cu rezorcinã-oxazolidinã. Pielea tãbãcitã cu rezorcinã-oxazolidinã este mai stabilã la biodegradare. CUVINTE CHEIE: piele tãbãcitã organic, piele tãbãcitã vegetal, biodegradare ÉTUDE COMPARATIVE SUR LA BIODÉGRADABILITÉ DU CUIR RÉSUMÉ. Cet article présente une étude comparative concernant la biodégradabilité des trois types de cuirs tannés de manière organique: cuir au tannage végétal, cuir tanné avec oxazolidine et cuir tanné avec résorcinol-oxazolidine, et trois types de cuir tanné avec des agents tannants inorganiques: à base de chrome (III), à base de Ti-Al et à base de Ti-Zr. Pour évaluer la biodégradation du cuir, on a utilisé comme méthode la norme EN ISO 20200:2005. On a effectué des analyses physicochimiques sur les cuirs au jour zéro et après 90, 120 et 220 jours de compostage. La conclusion de l'étude est que tous les types de cuir tanné étudiés subissent le processus de biodégradation, mais à des rythmes différents. Le cuir tanné avec oxazolidine et cuir au tannage végétal sont plus biodégradables que les cuirs tannés avec résorcinol-oxazolidine. Le cuir tanné avec résorcinol-oxazolidine est plus stable à la biodégradation. MOTS CLÉS: cuir au tannage organique, cuir au tannage végétal, biodégradation 73Revista de Pielarie Incaltaminte 1...
