Book excerpt: capable of subsisting on inorganic and organic carbons thus unaffected by limited light, and microalgae biofilm's low harvesting cost. Our results, as one of the first studies of this type, proved that microalgae biofilms under mixotrophic condition exhibited significantly higher productivity and quality of biofuel feedstock: 2-3 times higher of biomass yield, 2-10 times higher of lipid accumulation, and 40 - 60 % lower of ash content when compared to microalgae biofilms under autotrophic condition. Finally, for the third goal, we have evaluated the potential of using life cycle optimization (LCO) and Machine Learning in the sustainability analysis. Availability of CO2 emission from coal and natural gas power plants has been evaluated to be used in HRAP in an LCO model. We considered a hypothetical model of providing CO2 gases to the nearby HRAP system. Environmental effects have been optimized based on the following minimizing function 1) energy needed for pumping wastewater and CO2 function 2) water needed to produce pipes, and finally, function 3) eutrophication potential. The primary results indicate that an HRAP close to the WWTP is the optimized condition in a distributed system on the CO2 pipe. The second challenge that we have evaluated in our research is the application of machine learning. We collected some of those independent parameters that affect the normalized CO2 generation. The results indicate that for different accuracy scenarios the model can predict very well. For example, considering the 75% accuracy (the absolute error between prediction and actual data is less than 25%), our machine learning model can accurately predict in 1,822 out of 2491 WWTPs. Besides that, our work resulted in some additional applications and award in the area of Internet of Things, community engagement, and data mining.
Book Synopsis Sustainable Development of Algal Biofuels in the United States by : National Research Council
Download or read book Sustainable Development of Algal Biofuels in the United States written by National Research Council and published by National Academies Press. This book was released on 2013-01-18 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofuels made from algae are gaining attention as a domestic source of renewable fuel. However, with current technologies, scaling up production of algal biofuels to meet even 5 percent of U.S. transportation fuel needs could create unsustainable demands for energy, water, and nutrient resources. Continued research and development could yield innovations to address these challenges, but determining if algal biofuel is a viable fuel alternative will involve comparing the environmental, economic and social impacts of algal biofuel production and use to those associated with petroleum-based fuels and other fuel sources. Sustainable Development of Algal Biofuels was produced at the request of the U.S. Department of Energy.
Book Synopsis Algae and Environmental Sustainability by : Bhaskar Singh
Download or read book Algae and Environmental Sustainability written by Bhaskar Singh and published by Springer. This book was released on 2015-12-22 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the dynamic role of algae in a sustainable environment. Two major aspects, namely bioenergy and bioremediation, have been elaborated in various chapter contributed by scientists and teachers from different geographical areas throughout the world. Algal biofuels is an emerging area of equal interest to researchers, industries, and policy makers working or focusing on alternative (i.e. renewable) fuels. Algae have been an area of interest due to their wide range of applications. Over the last 5 decades, eukaryotic algae have been used in the aquaculture industry as feed for invertebrates, providing a rich source of antioxidants, dietary fiber, minerals and protein. More recently, there has been a focus on the use of algal biomass in the development of alternative fuels. The extraction of oil from algae has been widely explored as a much more viable feedstock than plant-based oils in large-scale fuel production. using algae as feedstock has the advantages that it doesn’t require arable land and that wastewater can be used as a source of nutrients in their culture. The multifunctional approach of algae includes pollution remediation, carbon sequestration, biofuels production, and delivery of value-added products. However, there are still some obstacles that need to be overcome to make their use as potential feedstock for biofuels techno-economically feasible. In order to maintain the sustainability aspect of algal biofuels, various aspects have to be studied and critically analyzed to assess the long-term sustainability of algal derived biofuels. This book discusses the role of algae as a promising future feedstock for biofuels. They are known to sequester carbon in much larger amounts than plants and as such the book also describes their phycoremediation potential for conventional as well as emerging contaminants. It describes the role of anaerobic digestion in algal biorefineries; bioreactions and process parameters; biogas recovery and reuse. The role of algal biofilm based technology in wastewater treatment and transforming waste into bio-products is discussed, and remediation of sewage water through algae is assessed. The book also describes the production of biohydrogen, bio-oil, biodiesel; and the major bottlenecks in their usage. The emerging characterization techniques of these biofuels (bio-oil and biodiesel) are described, as are the decolorizing potential of algae and the genetic engineering techniques that could enhance the production of lipids in algae. Other aspects of the book include the role of remote sensing technology in the monitoring of algae and a life cycle assessment of algal biofuels.

Book Synopsis Algae to Energy and Sustainable Development. Technologies, Resources, Economics and System Analyses. New Design of Global Environmental Policy and Live Conserve Industry by : Armen Avagyan
Download or read book Algae to Energy and Sustainable Development. Technologies, Resources, Economics and System Analyses. New Design of Global Environmental Policy and Live Conserve Industry written by Armen Avagyan and published by Createspace Independent Publishing Platform. This book was released on 2018-05-03 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to the current problem of global sustainable development; conflicts with the effective system working that allow making some conclusion for further compatibility improvements. At foremost, analyses look at recent international and own researchers dealing with algae technology and conversation to energy. The total global production of macroalgae is superior about 100 times compared to microalgae or 19 - 23 million tons by dry weight and market at $5 - 6 billion. Macroalgal biomass has a potential for the production of biofuels and can be used also for decentralized wastewater cleaning. The analyses showed that development microalgae producing have all necessary unlimited resources such as land and water (wastewater and groundwater). Food waste use for microalgae cultivation can lead to GHG mitigation up to 3.3 GTCO2e/yr or 8 % of global emissions. The UNEP ignored high carbon capture and storage (CCS) potential of algae. Simultaneously, international organization and researchers as main constraints for microalgae biofuels have described the cost of their production based on comparing with prices of oil fuels and crop biofuels. Comparison of the cost of microalgal biofuel production with a subsided prices of oil and crops biofuel is a methodical mistake as the governments have paid part of their fuel price from public funds as well as it is necessary to take into account also large scale production competitive benefits. It is stressed that many projects and Life Cycle Assessments (LCAs) are based on using fertilizers for nutrition microalgae. According to the ISO/TS 14067, we estimated day input of including fertilizers with nitrogen content in the total emissions of the product full life cycle by expanding of LCA boundary. Calculation emission by the use of last U.S. NPEL design of microalgae to biofuel showed that only used fertilizers with nitrogen content for the day microalgae biomass production release CO2 emission 63.56 kgCO2e per kg of the produced microalgae biomass. This is more that impact of CCS by algae cultivation - 1.83 kgCO2e per kg of algal biomass, gasoline and diesel emissions by combustion in motor vehicles (gasoline is realized 2.29 kgCO2/L (E10 - 2.21 and E85 - 1.61 kgCO2/L ) and diesel - 2.66 kgCO2/L (B5 - 2.65 and B20 - 2.62 kgCO2/L)) as well as sum of crude oils extraction-to-refining (4 to 50 gCO2e/megajoule (MJ) (about half of the total EU plants has extraction-to-refining emission from 4 to 9 gCO2/MJ) and combustion in motor vehicle emissions of 73 gCO2e/MJ). This proves that phototrophic growth of microalgae has no perspective for commercial production. The additional stressed issue is that in 2016, biofuel crops boost fertilizer industry and nitrogen fertilizer consumption intended to biofuels production. Therefore, it offered that first generation biofuel producers should seriously think about the use of feedstock yields originated by the use of organic agriculture approach. As a result of system analyses, it made the conclusion that sole main barrier for realizing of algae biofuel potential is ineffective international and governmental policies which create difficulties in the coupling of the goals between economic development and environmental activity. Therefore, we offered the new design of environmental police and relevant innovative financial mechanisms in a framework of Public/Private Partnership for archiving of effective investment flow to mitigation pollution. This policy based on recognizing of Life Conserve industry as the separate branch of production and each company which activity direct or indirect decrease pollution must receive payment for the impact of their products. Simultaneously, the analysis provides that near-term microalgae come to big feed additives market as feed additives for animals and for the fishmeal replacement in aquaculture due to competitive cost archived by technological advancement and benefits of their content.

Download or read book Algal Technologies for Wastewater Treatment and Resource Recovery written by Raul Muñoz and published by IWA Publishing. This book was released on 2019-07-26 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 80% of globally produced wastewater receives little or no treatment before it is disposed into the environment. Therefore, it is urgent to develop new wastewater treatment technologies that are sustainable in the broad sense of the word, i.e. not only produce high quality effluents, but also minimise energy expenses, recover energy and nutrients, and apply technology that is appropriate in relation to the availability of skilled personnel. This book compiles the main outcomes of recent efforts to improve the design of waste stabilisation ponds, and confirms the superior performance of high rate algal ponds as a result of process intensification. Anaerobic digestion devoted to biogas production continues to be the preferred strategy for the energy valorisation of the algal biomass, co-digestion with multiple high C/N ratio substrates gathering significant attention over the past years. The potential of algal biomass as a biosorbent for heavy metal removal (Cu, Ni, F) maintains its share in the research field of water bioremediation, while research on nutrient removal has focused on providing new insights on the mechanism of nitrogen and phosphorus removal from wastewater in algal–bacterial systems. Finally, it is worth noticing that breakthroughs in complementary fields of research such as nanotechnology or lighting technology are gradually being implemented in algal biotechnology, with new products such as nanoparticles for water disinfection or photobioreactors illuminated by low intensity LED panels. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field.
