Résumé : |
Advances in environmental protection legislation, along with the awareness of societies, leads industrialists, environmentalists and scientists, to search for production methods or industrial processes with lower environmental impacts. Within this philosophy, the maximum utilization of raw materials, wastes and by-products should be considered as a target for the leather industry. The anaerobic digestion of solid leather wastes may represent a possibility for energy recovery through biogas production. This gaseous fuel (biogas) is considered a renewable and carbon-free since the basic raw material is classified as biomass. This paper presents the potential for energy recovery through anaerobic digestion of different tannery wastes, tanned and untanned, based on the potential for biogas generation available in scientific literature using recent publications. The results show that collagenous materials can be efficiently degraded biologically to obtain a gas with high calorific value in sufficient quantities to supplement the energy demand of tanneries as a complementary source. The average heating values (Higher Heating Value, HHV) of biogas obtained under controlled conditions was found to be between 13.1 and 29.4 MJ.Nm-3 allowing an estimated energy potential of around 123 to 485 kWh per metric ton of rawhide processed. Considering the tannery energy consumption, the biogas may represent from 0.9 to 15% of the total energy demand or from 6 to 31% of the electrical demand. This initiative aims to increase the energy efficiency and improve the environmental quality of the tanning industry. |
