Download or read book Energy Analysis of Sweet Sorghum Ethanol Using a Bottom up Energy Return Ratio Matrix Approach written by John A. Veracruz and published by . This book was released on 2015 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between 2012 and 2013 the world increased biofuel consumption by 6.1% and if forecasts hold, according to the International Energy Agency, by 2050 27% of the world’s transport energy will come from biofuels. Rather than succumb to a shortage of corn, alternative feedstocks must gain the same traction corn has gained within the ethanol production industry. When considering an alternative feedstock what must also be considered it is that energy output from ethanol production exceeds the energy needed to produce one liter of alcohol. With origins traced back to Africa, sweet sorghum, or Sorghum bicolor(L) Moench, has gained traction as a viable ethanol feedstock due to the plant’s ability to reach a harvest maturity in as little as four months. With similarities to that of sugarcane, sweet sorghum’s stalk contains a relatively balanced amount of both insoluble and soluble carbohydrates. Although sweet sorghum will flourish with the appropriate amount of water, its drought resistance provides versatility other ethanol feedstocks do not possess. However, lower inputs, drought resistance, and the ability to grow on fallow land are all meaningless if growers miss a relatively short harvesting window, or even worse, allow fermentable sugars to decay by not expediting fermentation. If sweet sorghum ethanol is to displace any amount of corn and prove its feedstock viability, its energy balance must show more energy is output than is input. By using a bottom-up matrix based approach using energy return rations (ERRs), a product’s system may be evaluated to determine its usefulness to society. The Brandt et al. framework requires the creation of two matrices; a technology matrix, A, and an intervention matrix, B. Devising information from these matrices requires the use of three main vectors which serve as the foundation for calculating the desired ERR. Using this method in conjunction with four ERRs allows the study of energy processes used to create inputs for sweet sorghum pathways and possibly allude to how this energy is used to eliminate waste or improve efficiency through cleaner energy sources.
Download or read book Lignocellulose Conversion written by Vincenza Faraco and published by Springer Science & Business Media. This book was released on 2013-06-12 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.

Download or read book Evaluation of Sweet Sorghum Cultivars as a Potential Ethanol Crop in Mississippi written by David Scott Horton (II) and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum prices have made alternative fuel crops a viable option for ethanol production. Sweet sorghum [Sorghum bicolor] is a non-food crop that may produce large quantities of ethanol with minimal inputs. Eleven cultivars were planted in 2008 and 2009 as a half-season crop. Four-row plots 6.9 m by 0.5 m, were monitored bimonthly for °Brix, height, and sugar accumulation. Yield and extractable sap were taken at the end of season. Stalk yield was greatest for the cultivar Sugar Top (4945 kg ha -1) and lowest for Simon (1054 kg ha−1). Dale ranked highest ethanol output (807 L ha−1) while Simon (123 L ha−1) is the lowest. All cultivars peak Brix accumulation occurs in early October. Individual sugar concentrations indicated sucrose is the predominant sugar with glucose and fructose levels dependent on cultivar. Supplemental ethanol in fermented wort was the best preservative tested to halt degradation of sorghum wort.

Download or read book Advances of Basic Science for Second Generation Bioethanol from Sugarcane written by Marcos S. Buckeridge and published by Springer. This book was released on 2017-03-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the basic science recently produced in Brazil for the improvement of sugarcane as a bioenergy crop and as a raw material for 2nd generation bioethanol production. It reports achievements that have been advancing the science of cell walls, enzymes, genetics, and sustainability related to sugarcane technologies and give continuity to the research reported in the “Routes to Cellulosic Ethanol”, from Springer. The Introduction (Chapter I) explains how the National Institute of Science and Technology of Bioethanol, founded in 2008 in Brazil, became part of the main international initiatives that started to search for forms to use biomass for bioethanol production in Brazil, US and Europe. Part I reports the advances in plant cell wall composition, structure and architecture, and physical characteristics of sugarcane biomass. These discoveries are opening the way to increased efficiency of pretreatments and hydrolysis, being therefore important information for 2nd generation processes as well as for biorefinery initiatives. Part II focuses on the discovery and characterization of hydrolases from microorganisms that could be used in industrial processes. Recent advances in the search for hydrolases using metagenomics is reported. A great number of genes and enzymes from microorganisms have been discovered, affording improvement of enzyme cocktails better adapted to sugarcane biomass. Part III reports two key issues in the process of 2G ethanol, pentose fermentation and sugarcane genetics. These are the discoveries of new yeast species capable of producing ethanol more efficiently from xylose and the advances made on the sugarcane genetics, a key issue to design varieties adapted to 2G ethanol production. Part IV approaches sustainability through two chapters, one discussing the sustainability of the sugarcane agricultural and environmental system and another discussing how national and mainly international policies of Brazil regarding 2G ethanol production affected the country’s strategies to establish itself as an international player in renewable energy area.

This book was released on 2020-03-23 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production and utilization of sustainable energy toward maintaining a clean environment is a major challenge. At the same time, the continued depletion of fossil fuels and the global dependency on non-renewable fuels is a chief concern. Moreover, the long-term economic and environmental issues associated with the high utilization of fossil fuel, such as global warming, are also important, particularly in the context of the predicted increase in the global population to around 5 billion by 2050. In recent years, researchers have been investigating alternative, renewable fuels to replace fossil fuels. Of the various options, biofuels are especially attractive due to their low production costs and the fact that they are pollution free. Also known as transportation fuels, their energy is derived from biological resources or through the biological processes. Biofuels such as biohydrogen, biomethane, biogas, ethanol and butanol offer a number of advantages and can be economically produced from cellulosic biomass. As such, they can play a vital role in sustainably meeting future energy demands. Biofuels have the potential to become a global primary energy source, offering significant reductions in greenhouse gas emissions as well as opportunities to increase economic and social development in rural communities and reduce the problems associated with waste disposal. However, low yields and lack of process technology are some of the aspects that need to be addressed. This book offers an overview of existing biofuels and the technologies to solve the problems associated with their practical implementation. Evaluating the biofuel options and discussing the opportunities and risks in relation to resources, technologies, practices, markets and policy, it provides insights into the development of economically viable bioenergy industries.
