Abstract null null Bioenergy is seen as a key option to meet future energy demands and mitigate climate impacts. However, large-scale deployment of bioenergy can cause an additional pressure over land resources and correspondent sustainability impacts. Enhanced land management practices are fundamental to intensify land-based outputs under different climate mitigation scenarios. Bioenergy-livestock integration (BLI) is a win-win strategy to climate mitigation while ensuring food and fibers deman...
Abstract null null Bioenergy is expected to play an essential role in greenhouse gas (GHG) mitigation in the future energy sector. In Brazil, sugarcane electricity appears as a reliable option with low GHG emissions when compared to fossil alternatives. The sugarcane sector mostly produces electricity from bagasse, while straw (sugarcane tops and leaves) presents a vast potential for additional electricity production and mitigation of climate change. The suitability and potential of straw recove...

Technoeconomic and life-cycle analyses are presented for catalytic conversion of ethanol to fungible hydrocarbon fuel blendstocks, informed by advances in catalyst and process development. Whereas prior work toward this end focused on 3-step processes featuring dehydration, oligomerization, and hydrogenation, the consolidated alcohol dehydration and oligomerization (CADO) approach described here results in 1-step conversion of wet ethanol vapor (40 wt% in water) to hydrocarbons and water over a ...

Abstract Techno-economic analysis of first- and second-generation (1G2G) integrated sugarcane biorefinery producing ethanol and electricity was performed, exploring the virtues and limitations of dilute acid pretreatment. Process variables such as solid content in the pretreatment reactor, enzymatic hydrolysis time, and the possibility of pentose fermentation were pondered using computational tools and simulation platforms to assess the impacts of the variables overall production chain. Previous...

Abstract Approximately 7% of Brazilian electricity is generated from sugarcane biomass. Although this scenario is relatively optimistic when compared to the fossil-based energy matrix of other nations, there is a clear opportunity of expanding bioelectricity production in the country even more. Recent changes in the environmental legislation are progressively prohibiting burning before sugarcane harvesting in Brazilian Center-South region. Consequently, straw (i.e., sugarcane tops, dry and green...

Sugarcane straw has become available in large quantities in the field due to transition from manual to mechanical harvesting. Straw can be used as fuel for cogeneration systems of sugarcane mills to increase surplus electricity for commercialization. However, the exploitation of straw potential is still limited due to some challenges related to its agricultural recovery and industrial processing. The retrofit (additional installation) of existing sugarcane mills to process straw is an alternativ...

Abstract The aim of this study was to conduct an economic assessment of the entire polyhydroxybutyrate (PHB) production process by Cupriavidus necator , using citric molasses as carbon source and employing propylene carbonate as solvent coupled with different extraction pretreatment methods. Four extraction alternatives were assayed. The alternatives that uses high pressure and heat to pretreat the biomass showed equally lower production costs (US$ 4.28 per kg) and better economic indicators amo...

Abstract New models for renewable energy production are needed to simultaneously decrease greenhouse gases (GHG) emissions, use land more efficiently and replace large amounts of fossil fuel. Ethanol production and livestock feed integration as practiced in the United States (USA) is one model for ethanol production combined with animal feed production. Brazil, the second largest ethanol and beef cattle producer in the world, can adapt the USA model of corn ethanol and cattle integration conside...

Abstract Sugarcane hybrids have been developed through genetic engineering and plant breeding to produce lignocellulosic crops that are more susceptible for second generation biofuels production. Adequate evaluation of these plants requires process development combined with proper economic assessment. In this study, alkaline sulfite pretreatment of sugarcane biomass derived from four selected sugarcane hybrids was assessed for second generation ethanol production integrated with a first generati...
