One of Central America's oldest and largest sugar groups, Pantaleon Group of Guatemala, has chosen Praj Industries Ltd. to supply the technology and equipment for two ethanol plants. A 40 MMgy plant at Bio Etanol in Guatemala will be managed by Pantaleon; a second facility, a 27 MMgy plant at Ingenio Monte Rosa, Nicaragua, is owned by Pantaleon.

Praj's contract includes the supply of technology, engineering, main plant and equipment for fermentation, vacuum distillation using very low pressure exhaust steam, molecular sieve dehydrations and evaporation of vinasse (the still bottoms left after distillation of fermented sugarcane). The Central American plants will be the first in the region to use Praj's technology to evaporate vinasse using self-cleaning fluidized bed evaporators to concentrate the waste for use as liquid fertilizer.
