The de-chroming technology of leather chromium waste was proposed in our previous work.1 In this work, condensation adhesives based on urea-formaldehyde and phenol-formaldehyde were modified with protein hydrolysates. It is known that collagen hydrolysate of chrome-tanned leather waste added to dimethylol urea clearly limits formation of relatively unstable oxy-methylene bridges which may be regarded as potential source of formaldehyde emissions. The aim of this study was to verify the change of glue joint properties in following ways: influence of collagen hydrolysate on shear strength properties of glued joints under action of water and high humid conditions; increasing the water-resistance of glued materials, development of adhesive mixtures suitable for gluing of wood at higher moisture content, influence of collagen hydrolysate on lowering the formaldehyde emissions from wood based panels. The intended sources of protein hydrolysates were solid waste from leather production (e.g. chromium shavings and chippings, hypodermic and adipose ligament, leather chippings, gelatin production and food packing). These various analytical investigations of this study confirmed significant reduction of formaldehyde emission from wood based panels, increased water-resistance of glued materials, and conforming shear strength properties of glued joints. Application of collagen from de-chromed waste allows improvement of ecologic and economic parameters of bonding processes in the woodworking industry (e.g. eliminating of harmful effects on the environment and lowering of costs at keeping required quality).

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.

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.
