“…This indicates that fatliquoring increases tear strength, elongation at break and distension of leather. This trend resonates with results reported by [46] and [31]. The results for elongation of fatliquored leather agree with those previously published by [20,48,50].…”

“…Fatliquored samples recorded lower tensile strength and shrinkage temperature as compared to dyed samples. The same pattern was observed by [46] and [31]. The range of our results for fatliquored samples is comparable to other studies [47][48][49].…”

“…Results from this study show that leathers at both tanned and retanned stages of processing are appropriate for most of the leather applications. The margins of the results and patterns reported in this study are comparable to other related publications [28][29][30][31][32]. An increase in flexural endurance after retanning has also been observed by [33].…”

“…It should be noted that the gender differences in children's foot anthropometry is observed after puberty and may be a contributing factor for no anthropometric variations between the boys and the girls in this study. The result of this present study also supports race difference in anthropometry data [9], in which the Indonesian foot anthropometry data is smaller than Caucasian ones (for example Spanish children foot anthropometry data [31]).…”

Characteristics of the Footwear and Clothing Industry in terms of Waste ManagementThe leather industry covers a wide range of sectors ranging from the leather markets that provide the tanning industry with raw materials from meat abattoirs to the leather goods manufacturers. Some of those sectors are highly industrialised, others are based mainly on arts and crafts, and still others focus on trade and ancillary services. 1 Leather manufacture is one of the world's oldest handicrafts. Thanks to appropriate processing, we achieve an extremely durable raw material that is used for manufacturing common goods. The leather tanning process consists of a series of mechanical processes and chemical reactions. As a result, unstable raw leather is

Circular economy systems keep the added value in products for as long as possible and eliminate waste. Resources are kept within the economy when a product has reached the end of its life, so that they can be productively used again and again and hence create further value. In this context, the specialists from leather and footwear sector look for innovative solutions for utilization of leather wastes for obtaining of new bio-composites with application in construction industry. This paper presents utilization of leather wastes for obtaining construction materials for pedestrian walkways (paving blocks) containing leather fibers obtained from leather waste and their physicalmechanical and structural characterization. KEY WORDS: leather waste, leather fibers, concrete, bio-composite BIO-COMPOZITE CU FIBRE DE PIELE ŞI CIMENT -CARACTERIZARE FIZICO-MECANICĂ ŞI STRUCTURALĂREZUMAT. În economia circulară, sistemele menţin valoarea adăugată a produselor cât mai mult timp posibil şi elimină deşeurile. Resursele se păstrează în cadrul economiei atunci când un produs a ajuns la sfârşitul vieţii sale, astfel încât să poată fi folosit din nou şi din nou şi, prin urmare, să creeze o valoare suplimentară. În acest context, specialiştii din sectorul pielăriei şi încălţămintei caută soluţii inovatoare pentru utilizarea deşeurilor de piele pentru obţinerea unor noi bio-compozite cu aplicaţii în industria construcţiilor. Această lucrare prezintă utilizarea deşeurilor de piele pentru obţinerea materialelor de construcţie pentru pavele pietonale care conţin fibre de piele obţinute din deşeurile de piele şi caracterizarea fizico-mecanică şi structurală a acestora. CUVINTE CHEIE: deşeuri de piele, fibre de piele, beton, bio-compozite BIO-COMPOSITES AVEC DES FIBRES DE CUIR ET DE CIMENT -CARACTÉRISATION PHYSICO-MÉCANIQUE ET STRUCTURELLERÉSUMÉ. Les systèmes d'économie circulaire conservent la valeur ajoutée des produits le plus longtemps possible et éliminent les déchets. Les ressources sont conservés dans l'économie lorsqu'un produit est en fin de vie, de sorte qu'il peut être utilisé encore et encore, créant ainsi une valeur ajoutée. Dans ce contexte, le spécialiste du secteur du cuir et de la chaussure recherche des solutions innovantes pour l'utilisation des déchets de cuir afin d'obtenir de nouveaux bio-composites destinés au secteur de la construction. Cet article présente l'utilisation des déchets de cuir pour obtenir des matériaux de construction pour les chaussées piétonnes contenant des fibres de cuir dérivées de déchets de cuir et leur caractérisation physico-mécanique et structurelle. MOTS CLÉS : déchets de cuir, fibres de cuir, béton, bio-composites
