<p><strong><em>Abstract:</em></strong> <em>Renewable energy necesity have promote research on ethanol production technology. Ethanol is the potential renewable energy substituting gasoline. However, the conventional problem is high price of the ethanol. The objective of this research was to test the performance of alternative process in producing ethanol, i.e. combination of fermentation process with ethanol stripping in trickle bed bioreactor. The experimental was using Saccharomyces cerevisiae FNCC 3012 and sugarcane bagass as bed particle. It was devided into 2 process steps of biofilm development and ethanol production. Biofilm development was done by circulating medium in bioreactor aerobically. Duration of the biofilm development was 24 hours and followed by ethanol production step which was combinating anaerobic fermentation and stripping process using nitrogen. Production process was conducted for 36 hours lifetime. This method resulted biofilm developing in fermentation medium, not on baggas surfaces. Consequently, ethanol production happened in circulated fermentation medium. The productivity of this method of ethanol production process was not better than the conventional process. Neverherless, the experimental showed that the product stripping and fermentation could be done simultaneously. The stripping process increased ethanol product concentration up to 25% higher than in the broth</em>.</p><p> <strong><em>Keywords:</em></strong> <em>ethanol, Saccharomyces cerevisiae FNCC 3012, trickle bed bioreactor, stripping, biofilm</em></p>

Abstract The use of biomass for renewable energy production is one alternative to reduce the environmental impacts of energy production worldwide. Sugarcane-based ethanol is one of the most widespread biofuels in the road transport sector and its development has been encouraged by strong incentives on production and use in several countries. The growing realization on the environmental impacts of ethanol production indicates the need to increase the efficient utilization of biomass resources by optimizing the production chain sustainably. This paper evaluates enhancements in the ethanol production chain quantitatively by identifying opportunities for agricultural intensification and investments in advanced biorefineries in a least-cost optimization model. Results of our model show that significant cost and environmental benefits can be achieved by modernizing sugarcane agriculture in Bolivia. Demands for ethanol and sugar can be met cost-effectively by increasing sugarcane yields from the current country-average of 55.34 ton/ha to 85.7 ton/ha in 2030 with a moderate cropland expansion of 11.4 thousand hectares in the period 2019-2030. Our results further suggest that it is cost-optimal to invest in efficient cogeneration in biorefineries to maximize the renewable energy output and the economic benefits of sugarcane ethanol. Finally, biofuel support in the range of 8-10 US$/GJ is required for investments in second-generation ethanol in biorefineries to be cost-competitive in the medium-term..

This study presents a new simulation model developed with ASPEN Plus of waste biomass gasification integrated with syngas fermentation and product recovery units for bioethanol production from garden waste as a lignocellulosic biomass. The simulation model includes three modules: gasification, fermentation, and ethanol recovery. A parametric analysis is carried out to investigate the effect of gasification temperature (500–1500 °C) and equivalence ratio (0.2–0.6) on the gasification performance and bioethanol production yield. The results reveal that, for efficient gasification and high ethanol production, the operating temperature range should be 700–1000 °C, as well as an equivalence ratio between 0.2 and 0.4. At optimal operating conditions, the bioethanol production yield is 0.114 kg/h per 1 kg/h input garden waste with 50% moisture content. It is worth mentioning that this parameter increases to 0.217 kgbioethanol/kggarden waste under dry-based conditions.
