Energy Recovery from Sugarcane-Trash in the Light of 2nd Generation Biofuels. Part 1: Current Situation and Environmental Aspects

摘要

The importance of Sugarcane-Trash energy use, also called Sugarcane Agricultural Residues (SCAR) or Barbojo was analyzed in the light of 2nd generation Biofuels. The current challenges and opportunities of SCAR energy use were treated. An analysis focused on current Brazilian situation and experiences around the world, was carried out. The most probable routes for 2nd generation Bioethanol production suitability: Biomass to Liquid and Bio-enzymatic were compared in Brazil. The Brazilian Sugarcane Agro-Industry particularities and its influence on SCAR energy use were analyzed. The most probable use of SCAR, in a short and mid term, is as boiler feedstock. The key environmental aspects related to SCAR use were analyzed. The SCAR decomposition process and its influence into the CO_2 emission reduction were explained. The weed control effect of SCAR left in the field was examined.
