“…Based on moderate and high scenarios, Islas et al [16] presents a technical potential for 2004 of 71 PJ/year from sawmill residues and harvesting residues, 997-1791 PJ/year from natural forest and 450-1246 PJ/year from plantations. Moreover, García et al [17] calculates an energy potential of 64 PJ/year from wood pellets burned for heat and 108 PJ/year from traditional wood-fuel for efficient cook stoves.…”

While considering constraints in regard to sustainability, this paper reviews the development of a methodology to assess the introduction of bioenergy supply chains in Mexico based on forest woody biomass. Three research modules include analyses of forest biomass utilization residues that originated from: (1) harvesting activities, (2) non-extracted stands and (3) sawmills. A regional case study focusing on tree species of commercial importance (pine, oak and fir) in the 10 provinces with the highest timber production located in the north and central-south part of the country, is analyzed. After applying the methodology, the theoretical potential of available woody biomass for energetic use amounts to 6,357,482 m 3 . When applying the sustainability constraints, the technically feasible supply of forest woody biomass for energetic use sums up to 5,798,722 m 3 , which relate to a technical energy potential of 45.96 PJ for 2013. Moreover, a biomass energy flow chart showing energy values for each analyzed source and species is presented. Monte Carlo simulations were carried out for each cost involved in utilizing the resulting available woody biomass for energetic use. In the absence of national studies which include forest operations and bioenergy transformation to calculate the sustainable energy potential, the developed methodology adds innovation for assessing woody biomass availability.

“…The former can be minimized by using excess ethanol, and the latter is neglected in this process analysis because it occurs only in the presence of water. The use of ethanol of vegetable origin in its manufacture process, increases the interest of ETBE or bio-ETBE as an oxygenated additive [3,4]. Accurate knowledge of the thermodynamic properties of ETBE and hydrocarbon mixtures is important to improve the thermodynamic models used in the design, simulation and production processes.…”

ResumenLa lignina y la celulosa no siempre pueden emplearse en su forma natural, por ello deben hidrolizarse, y esto puede llevarse a cabo con enzimas, con ácidos o con bases; las dos últimas presentan la ventaja de mejorar la hidrólisis de la celulosa. La alternativa de emplear residuos lignocelulósicos en la producción de bioetanol y de proteína unicelular constituye hoy día una posibilidad altamente prometedora por su amplia disponibilidad en el mundo. En el presente trabajo se evaluaron los diferentes métodos de hidrólisis del residuo lignocelulósico de la planta de Zea mays (Poaceae) "maíz amarillo duro" con la finalidad de determinar el método más adecuado para la máxima obtención de azúcares reductores totales ART y poder así utilizarlos como sustrato en procesos fermentativos para la producción de proteínas unicelulares y bioetanol. La materia prima empleada fue planta seca y fraccionada de un tamaño de partícula <1,0 mm y se evaluó mediante métodos de hidrólisis químicos, físicos y la combinación de ambos, utilizando como soluciones extractantes agua destilada estéril, ácido sulfúrico e hidróxido de sodio al 1,25 %. La relación plantasolvente utilizada en todos los tratamientos fue de 1:10. La determinación de los azúcares reductores totales se realizó en los filtrados obtenidos de cada uno de los tratamientos empleando el método de Folin-Wu. Los resultados indican que la máxima concentración de azúcares reductores totales obtenidos corresponde a 82,94 y 84,18 g/L, y se obtienen después de realizar la hidrólisis mixta como resultado de la combinación del método físico y físico-químico.
