TannageTags : 'Déchets de tannerie' 'Production biogaz' 'Pile à combustible' Index. décimale : 665.77 Production de gaz industriels à partir du charbon, du pétrole, des déchets Résumé : Wastes from tanneries present a good opportunity to produce biogas anduse it in high temperature fuel cells for combined heat and power systems. Biogas is considered a renewable fuel, domestically produced and free of carbon emissions, while molten carbonate fuel cells are ultra-clean and highly efficient power generators. In this paper, we study the economic viability of a fuel celle (considering capacities from 300kW to 1200kW) operating on biogas. The results are based on Spanish legislation, which establishes a special feed-in tariff bor biogas and cogeneration. Paybacks range from 5.7 to 8.5 years depending on the fuel cell capacity. Due to the high investment and operating and maintenance cost, the Spanish feed-in tariff for cogeneration using biogas is not enough to make the project economically viable in a short-term. Further fuel celle price reduction and longer lifetime as well as new government subsidies are required.

Hydrolyse enzymatiqueTags : 'Copeaux tannerie' 'Protéase 1398' 2709' Alcalase Papaïne Pepsine 537' Trypsine 'Titration formaldehyde' Electrophorèse 'Ges dodécyl sulfate-polyacrylamide sodium' 'Ultrafiltration centrifuge' Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Collagen hydrolysates were extracted from tannery skin shavings through enzymatic hydrolysis by using protease 1398, protease 2709, alcalase, papain, pepsin, protease 537 and trypsin, respectively. The hydrolytic degree and molecular weight distribution (MWD) of the hydrolysages were evaluated by the formaldehyde titration method, sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), tricine-SDS-PAGE and centrifugal ultrafiltration. It was found that the MWD of the as prepared collagen hydrolysates has a close correlation with the hydrolytic degree, and greatly depends on the enzyme employed. The low molecular weight (MW) collagen hydrolysates, with relatively high hydrolytic degree, were obtained by enzymatic hydrolysis using protease 1398, protease 2709, papain and alcalase. More than 60% (mass ratio) of the fractions in these four hydrolysates were in the molecular weight range of <10kDa. The use of protease 537 produced medium-MW collagen hydrolysages where 40% of the fractionswere of 10-30kDa. The high-MW collagen hydrolysages that include about 66% fractions with molecular weights higher than 20kDa were obtained by using pepsin, accompanied by the lowest hydrolytic degree. This research provides a potential approache for molecular weight and molecular weight distribution control collagen hydrolysates by enzymatic hydrolysis ot tannery skin wastes.

Cuirs et peaux -- Déchets -- RecyclageTags : 'Déchets solides de cuir' cheveux tannerie' non tannés' cuir contenant du chrome' 'Boues fini' Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather making is the process of converting raw hides into leather. Amounts of solid waste containing hazardous and high value components are generated during this process. Therefore, the elimination of the potential pollution and resource utilization of leather solid waste are the primary research hotspots. Herein, we comprehensively review the recent advances in the resource utilization of leather solid waste generated from chrome tanning including the utilization of tannery hair waste, untanned solid waste, chrome-containing leather solid waste, tannery sludge and finished leather waste, emphasizing on the general and novel utilization approaches. Finally, the remaining challenges and perspectives were summarized, in order to accelerate the development of resource utilization of leather solid waste.
