“…However, the main source of this energy, so far, is sugar cane [20], with Brazil as the main biofuel producer in the region [21], followed by Colombia [22]. Other renewable energy resources are also considered important, such as palm oil [23] and biogas [24,25].…”

“…Biomass resources or feedstock can be: (I) agriculture, generally including agricultural residues such as cane bagasse, oil palm and corn, among others [31]; (II) forest residues consisting of non-usable products resulting from harvesting or sawing processes, products from agroforestry systems, and short-rotation woody crops . Sugar cane is the most important feedstock in Brazil for transport, which continues to grow in production [22] but other important crops produced in the Latin America region include soya, oil palm, castor oil, peanut and sunflower oil, parsed, and jatropha [22,23].…”

Studies related to biomass production, with a focus on energy uses for short-rotation woody crops (SRWCs), are limited in Latin America. The research that is available relates to a variety of tested SRWC species (50 species), however, the most important species are Populus, Salix, Eucalyptus, Acacia, and Gmelina arborea. In the existing studies, stocking densities varied from 1111 to 20,000 trees per hectare, with square or rectangular spacing. One important advantage of SRWC systems in this region, compared to most regions worldwide, is the predictability of biomass yields due to the tropical climate conditions of the majority of the Latin American countries. Rotations of three and four years can be projected to produce total biomass yields of 30–50 tons/ha, with increments of 10–20 tons/ha/yr. Fertilization is performed in SRWC with the aim of preventing soil degradation and maintaining further production. In regards to possible uses of biofuel generated from SRWC in Latin America, an inconvenience is that there are neither well-established harvesting systems nor conventional pre-treatments to process the biomass. Processes that are available in the region that use biomass from SRWC for energy production are gasification and pellet production. Other potential biofuel processes, such as torrefaction and biochemical conversion, are limited in this area.

Simulation of macauba palm cultivation: an energy-balance and greenhouse gas emissions analysis The expansion of the production and use of bioenergy is deemed as one of the most efficient mechanisms to reduce greenhouse gas (GHG) emissions. Nevertheless, the environmental impact of the production processes for many raw materials remains unexplored. Several studies have pointed to macauba palm (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) as a promising species for biofuel production in the tropics, but investigations on the environmental benefits of the cultivation of this palm as a source of raw material for biofuel production have not been reported so far. The aim of this work has been to conduct an analysis of macauba production system in terms of GHG emissions and CO 2 uptake for a productive cycle, considering a 30-year horizon. The energy conversion efficiency (energy outputs/inputs ratio) per unit area of land has been put in relationship with crop productivity and related to the dilution effect of production inputs. Results of the simulation estimate that GHG emissions from macauba crop would be around 180 Mg CO 2 eq•ha-1 , whereas CO 2 fixation during cultivation would range from 796 to 1137 Mg CO 2 eq•ha-1. The energy assessment shows that the net energy balance for macauba crop would reach 512.3 GJ•ha-1 and that the energy efficiency would be ca. 24.2 GJ•GJ-1. These results, compared with those of traditional energy crops such as sugarcane, oil palm, sunflower, corn or jatropha, suggest that macauba crop may have the potential to outperform them in terms of efficiency. The domestication and exploitation in extensive farming of this species as an agroforestry crop, although still at an early stage, has a bright future.
