This study summarizes research on farm-, local-, regional-, and macro-level economic effects of ethanol production. Given current production levels, the ethanol production industry annually employees approximately 3,500 workers, pays out nearly $132 million in worker salaries, generates over $110 million in local taxes, and takes in some $2 billion in government incentive payments. Projections for a 60 million gallon per year ethanol plant indicate an annual increase in corn usage of 21 million bushels, a one-time capitalization of $75 million, an increase in local corn prices of between $0.06/bushel and $0.12/bushel, a 54 direct and a 210 indirect jobs created, an increase in local tax revenues of $1.2 million, a decrease in federal commodity program outlays of $30 million, and an increase in ethanol production incentives (federal only) of around $30.5 million.

Improve Mass Transfer

Previous studies have shown that pretreatment of corn slurries using ultrasound improves starch release and ethanol yield during biofuel production. However, studies on its effects on the mass transfer of substrates and products during fermentation have shown that it can have both beneficial and inhibitory effects. In this study, the effects of ultrasound on mass transfer limitations during fermentation were examined. Calculation of the external and intraparticle observable moduli under a range of conditions indicate that no external or intraparticle mass transfer limitations should exist for the mass transfer of glucose, ethanol, or carbon dioxide. Fermentations of glucose to ethanol using Saccharomyces cerevisiae were conducted at different ultrasound intensities to examine its effects on glucose uptake, ethanol production, and yeast population and viability. Four treatments were compared: direct ultrasound at intensities of 23 and 32 W/L, indirect ultrasound (1.4 W/L), and no-ultrasound. Direct and indirect ultrasound had negative effects on yeast performance and viability, and reduced the rates of glucose uptake and ethanol production. These results indicate that ultrasound during fermentation, at the levels applied, is inhibitory and not expected to improve mass transfer limitations.

Production Industry

Regardless of the fact that we have long been warned of the negative impact of industrial farming, rural communities are being wiped out as local producers, like Riverbend Gardens, are put at risk in favour of urban expansion. The industrial food production industry is unsustainable, leading to increased energy consumption and food costs because of the gross use of energy to transport food hundreds kilometres from where it is produced. Toxic chemicals used to combat swarms of pests that are nurtured by acres of single crop farming have lead to the increase of these substances in our environment. The growing disconnection between ourselves and how our food is produced, fostered by diminishing farm communities, allows us to continue as we always have, until our current system collapses. This will have a deleterious effect on our health and our environment. Many of the answers to the problems we face in our food production industry lies in support for our small, local food producers. Located within Edmonton city limits, sustainable, family run, Riverbend Gardens, is at risk of being wiped out if government and consumers do not recognize the importance of small producers and their part in solving the food industry’s failures.

The large application potential of micro-algae in the clean energy, biopharmaceutical and nutraceutical industries have recently drawn a substantial world interest. Biofuels, bioactive pharmaceutical drugs and food additives are organic, natural and economical sources. As biofuels, they have a good cost, renewability or environmental replacement for liquid fossil fuels. Microalges provide productive biomass feedstock for biofuel as demand for biofuels rises worldwide. These resources may be processed into biodiesel with ample supplies of biomass in rural communities. The cultivation of genetically modified algae in recent years has been pursued to promote the marketing of algae. In particular, this would benefit society if linked with a successful policy on algal biofuels and other by-products in the government. In terms of survival of the world's current problems, Algal technologies are a transformative but complementary tool. Algal fuel marketing remains a bottleneck and a threat. It is technically possible to have a big output but it is not economic. This study therefore focuses principally on problems in commercial development of biological microalgae and potential strategies for overcoming this challenge.

Simultaneous Saccharification

Utilization of biomass for production of second generation bioethanol was considered as a way to reduce burdens of fossil fuel in Pakistan. The materials wheat straw, rice straw, cotton stalk, corn stover, and peel wastes were used in this experiment. Various parameters, such as acidic and alkali pretreatment, enzymatic hydrolysis by cellulases, and effect of proteases inhibitors on ethanol production, were examined. Fermentation was completed by the yeasts Saccharomyces cerevisiae and Clostridium thermocellum separately, and their ethanol production were compared and maximum ethanol yield was obtained with wheat straw i.e.,11.3 g/L by S. cerevisiae and 8.5 g/L by C. thermocellum. Results indicated that a higher quantity of sugar was obtained from wheat straw (19.6 ± 1.6 g/L) followed by rice straw (17.6 ± 0.6 g/L) and corn stover (16.1 ± 0.9 g/L) compared to the other evaluated biomass samples. A higher yield of ethanol (11.3 g/L) was observed when a glucose concentration of 21.7 g/L was used, for which yeast fermentation efficiency was 92%. Results also revealed the increased in ethanol production (93%) by using celluases in combination with recombinant Serine protease inhibitors from C. thermocellum. It is expected that the use of recombinant serpins with cellulases will play a major role in the biofuel production by using agricultural biomass. This will also help in the economics of the biofuel.

Abstract A growing interest in cellulosic biofuels, coupled with the economic challenges faced by nonindustrial private forestland (NIPF) owners of the Southern United States, presents a unique opportunity to useforest biomass as a feedstock for developing bioenergy markets. This study uses a cost-benefit analysis framework to calculate the profitability for three simulated NIPF slash pine (Pinus elliottii) plantations under multiple feedstock production levels. Also, the unit cost of cellulosic ethanol production considering both the two-stage dilute sulfuric acid (2SDSA) and proposed synthesis gas ethanol catalytic conversion (SGECC) processes is calculated through a discounted cash flow methodology. The results show that the bioenergy market opportunity increases land values by $28.56–37.50/ac. The calculated unit cost of production is found to be $2.39/gallon under the 2SDSA process and $1.16/gallon for the SGECC process. The overall analysis indicates that ethanol production from Southern slash pine plantations offers a promising option for biofuel production, but that further advancements are necessary in the ethanol conversion phase.

This study analyzes the potential impacts of expanded ethanol production on southern agriculture. Results of regression analysis suggest that acreage planted for field crops (corn, cotton, soybeans, and wheat) is inelastic with respect to relative prices. The results provide statistical evidence of potential significant acreage shifts favoring corn over cotton, soybeans, and wheat. Simulations indicate that higher corn prices will increase corn acreage, but the South continues to be a deficit corn region. U.S. corn production is capable of supplying domestic demand for ethanol, feed for livestock and poultry, and other uses, while maintaining exports at more than 2 billion bushels annually.
