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.

Renewable energy to power tanneries / Luisa F. Cabeza in LEATHER INTERNATIONAL, Vol. 212, N° 4805 (11-12/2010)

Thermal energy is usually supplied with fossil fuels. In previous papers, the authors have shown a real possibility in the use of renewable energies such a solar thermal energy in tanneries around the world. However, the amount of electricity needed in the tannery process is much higher and this electricity usually is taken from the grid. Lately, the price of this resource has been increasing rapidly. Up to now renewable energies for electricity production have not been considered and only a few tanneries, mainly in Europe, use cogeneration as electricity supply despite the economic benefits of this technology. In this paper, the authors will present a viability study for the use of renewable energies for electricity supply in tanneries. The renewable energies considered are solar photovoltaic energy and wind energy.

Use of Cangilones drums to give water and energy savings in the beamhouse / Josep Maria Morera in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 91, N° 1 (01-02/2007)

Tannage Résumé : The tannery industry uses huge amounts of water and increasingly more energy. Any attempt to reduce this use would result in economic savings in the processing of hides. It can be seen in this paper that the use of new types of drums for processing leather, called Cangilones drums [cangilones = scoops/buckets], can result in important technical advantages for the tanneries as well as water and energy savings. The technical advantages are derived from the design of the drums. This design determines the physical movement of the load inside the drums. In the Cangilones drum, the movement of the hides is caused by gravitational forces and the float moves with the hides. Consequently, the penetration of chemicals is greater and the wastewater is more highly exhausted. Less float is needed for processing the hides and water savings are thus obtained.
