CARDONA, Eliana M; RIOS, Luis A  and  PENA, Juan D. Availability of Grasses and Forages as Potential Lignocellulosic Materials for Bioethanol Production in Colombia. Inf. tecnol. [online]. 2012, vol.23, n.6, pp.87-96. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642012000600010.

A review on the most common species of grasses and forages in Colombia to determine their potential use as lignocellulosic materials for the production of fuels like bioethanol and biobutanol is presented. For this, location, production yield per hectare and per year, lignocellulosic composition and ethanol yield are considered as main characteristics for determining their potential use. As result, elephant grass and king grass, are presented as the most appropriate ones for their exploration in biofuel production processes with green forages yields per acre per year between 360 and 400 ton and between 240 and 360 ton, respectively. Furthermore based in its cellulose and hemicellulose concentration, theoretical ethanol yields of 466,9 L/dry ton of elephant grass and 449,7 L/dry ton of king grass are obtained.

Keywords : grasses and forages; lignocellulosic composition; ethanol yield; bioethanol.
