The aims of this work were to determine the specific biogas yields of steam-exploded sugarcane straw and bagasse as well as to estimate their energy potential under Brazilian conditions. Steam-explosion was carried out under different time and temperature conditions. The specific biogas yields were analyzed in batch-tests according to VDI 4630. Results have shown that steam-explosion pre-treatment increased the specific biogas yields of straw and bagasse significantly compared to the untreated material. The utilization of these by-products can contribute to 5% of the total energy consumption and thereby higher energy independence in Brazil. Further efforts in defining the optimum pretreatment conditions with steam-explosion as well as implementing this technology in large scale plants should be made.
本研究旨在确定蒸汽爆破后的甘蔗秸秆和蔗渣的具体沼气产量，并评估在巴西条件下的能源潜力。蒸汽爆破在不同的时间和温度条件下进行。具体沼气产量根据 VDI 4630 在分批试验中进行分析。结果表明，与未处理的材料相比，蒸汽爆破预处理显著提高了秸秆和蔗渣的特定沼气产量。这些副产品的利用可以贡献总能源消耗的 5%，从而提高巴西的能源独立性。应进一步努力确定最佳的蒸汽爆破预处理条件，并在大型工厂中实施这项技术。
