They are extremely cheap and widely available to exploit with the technology and infrastructures that have been put in place. Krozer, Yoram. Print. Thanks so much for the introduction. Their purpose is to further convince you and examine divergent points of view. The whole ideology of using switchgrass as source for biofuels is become an actuality! Cellulosic ethanol from switchgrass, poplar, forest residue: USA: 70–80: 10–102 [27] Cellulosic ethanol: USA: 93: 86 [28] Cellulosic ethanol from wheat straw: UK: 78–102: 88–98 [45] Cellulosic ethanol from poplar and Fischer–Tropsch diesel from residual wood: Europe: N.A. If we take into consideration the number of PROs and the number of CONs, the difference is amazing. Adewumi, Michael A. The repeated cultivation of biofuel-producing-crops leads to soil erosion. Switchgrass is a good option when it comes to biofuels because it is one of the most dominant types of grass found in North America, especially in Canada and parts of the United States of America. No harmful sulfur or mercury emmisions . 600,000 tonnes per year). We are constantly reminded of various predicaments in the world caused by humans. That would be a factor of price hikes in the food sector. Switchgrass itself is a lot more productive if a large quantity of it is yielded. I hope you like this blog. This would ensure that we would cultivate large quantities of the grass without it taking away from food production, as it is unable to grow in soils unsuitable for food crops. The reason switchgrass is more productive after it is established is simple. There are few definitive comparisons on whether a seedbed prepared using clean tillage or some form of minimum tillage is the better method for establishing switchgrass. The second sector, manufacturing the ethanol would profit from selling the fuel to the government and car manufacturers. This would also attract various employments from different people who would be interested working with a newer technology. So, fertilizers are used for production. Auburn University. 28 Oct. 2012. Another reason is monoculture; this is when the same crop is produced year after year. We use fossil fuels to heat our houses in the winter and to cool them down in the summer. This entails adding water and special enzymes to the cellulose. One of the biggest advantages of biomass production from algae is its high energy content. CBC/Radio Canada, 09 June 2008. Switchgrass also promotes biodiversity as there are various species that live within the plant such as fungal endophyte. Eucalyptus trees and tropical … I have dedicated this blog to the research and development of BIOFUELS. Advantages & Disadvantages. Examining the advantages and disadvantages of switchgrass as a biofuel, November 30, 2012 11:40 am / Leave a comment. This type of equipment is available very widely across farms. This is resulting in many problems, as fossil fuels are a non-renewable source and are predicted to run out sooner, rather than later. The first being the escape of Formaldehyde and Acetaldehyde into the atmosphere through exhaust tubes in cars. Don’t worry, I’m just kidding. In Canada, fossil fuels represent approximately 75% of our energy. CRUICKSHANK, W. H., J. E. ROBERT, and C. R. SILVERSIDES. – Technology & Science – CBC News.” CBCnews. 28 Oct. 2012. 3.6. Comparison of … “Biomass Energy.” The Canadian Encyclopedia. A very descriptive animation about the fabrication of ethanol. Over all, I am most definitely for the developement and advancement of the use of switchgrass and biofuels. We use fossil fuels when we drive our cars. 27 Oct. 2012. They have the ability to retain nutrients in the soil and remain prosperous for many years to come. Web. 28 Oct. 2012. Currently in Canada,  our infrastructures are focused primarily on biodiesel. Plus, since Canada already has abundance supplies of switchgrass, we could export this, which would improve our economy further. The reason switchgrass should be considered as a biofuel in Canada is due to its geographic situation. They are less expensive. Advantages and Disadvantages of Biomass. The reason switchgrass should be considered as a biofuel in Canada is due to its geographic situation. In addition, there  is also the problem of fossil fuels being finite sources, as there is a limited supply. This factor makes sure that switchgrass can be grown in a very sustainable way. After all, you have to remember that “the greener today, the cleaner tomorrow!” ;). “Commodities: Field Crops: Switchgrass.” Switchgrass Description. Biofuel advocates frequently point out the advantages of these plant- and animal-based fuels. It is easily harvested, does not take away from food production, contributes to fuel security and soil fertility. As previously stated in “Why SWITCHGRASS?”, the carbon dioxide emissions would be much lower that of any other source of energy. The first sector, farming and agriculture would profit from growing the switchgrass. Switchgrass itself is a warm-seasoned perennial plant native to North America. Wang also found that switchgrass ethanol may require 70 percent less fossil fuel to produce than gasoline and E85 ethanol -- a mixture of 85 percent ethanol and 15 percent gasoline -- emits 86 percent fewer GHGs than gasoline does. This is an important point as this means that in order to grow switchgrass, we do not have to give up any food crop land. Switchgrass behaves like Miscanthus early in the growing season, drying out the soil. Finally, the tertiary sector would benefit from distributing the fuel to consumers. 23 Oct. 2012. So, in conclusion, everyone would greatly profit from the production and transformation of switchgrass into a biofuel. Ethanol fuel pros and cons show that this biofuel has great promise and potential, and when it is switchgrass ethanol the pros are increased while there are fewer disadvantages. Switchgrass itself is a warm-seasoned perennial plant native to North America. Until that day comes, a job loss in the fossil fuel sector is unlikely. Using switchgrass pellets for heating purposes is an also extremely beneficial options. This would protect biodiversity in the water as water pollution is one of the main factors in loss of species in the water. In fact, since switchgrass has such deep and dense roots, it absorbs nutrients into the ground and can slowly start transforming bad soil into good quality soil. Biodiesel and bioethanol are two widely used forms of biofuels. Leftover residue from farmers could be collected and, if used correctly, be contained and used for millions of tons of energy. London: Springer, 2012. Switchgrass adds organic matter to the soil, this is due to the glomalin in its roots, a glycoprotein that helps store carbon. Carbon neutral . This is extremely efficient as opposed to other biofuels, as we truly would be getting use out of the whole blade. Effects on Economy. The use of fertilizers to enhance production leads to the emission of Nitrous Oxide into the atmosphere. Tree plantations reduce biodiversity. We definitely have the infrastructures available, but the cost and research aspects of implanting this program would be extremely expensive. Thanks Gunther, next up we have Ernest Mack who will talking to us about from the standpoint of a fuel manufacturer. Nothing would go to waste when refining the blades into ethanol. biomass to biofuel. “Given the levels of soil carbon sequestration we found, coupled with the high net energy balance and low emissions of greenhouse gases, switchgrass is a … Due to industrialization and human development, there is a dangerous increase in pollutants in the atmosphere. I bet the suspense is killing you… What is this magical thing I speak of? Advantages. During the bioconversion process, the lignin fraction of switchgrass can be burned to provide sufficient steam and electricity to operate the biorefinery. The University of Tennessee implanted a research program  with the government wear approximately seventy million dollars of taxpayers money were used towards the plan to produce ethanol from switchgrass. CBC/Radio Canada, 09 June 2008. In addition, various species live with switchgrass such as fungal endophyte, therefore the grass promotes biodiversity and an excellent wildlife habitat as more species will be able to have a habitat. However, we also need to be focusing on the industries in Canada. As the seasons become colder, switchgrass rests dormant and it will not grow. Monti, Andrea. The researchers harvested switchgrass from five CRP fields in southern Wisconsin in August, 1996. Switchgrass itself is a warm-seasoned perennial plant native to North America. They come from biomass, which means anything derived from biological matters. Energy crops – switchgrass, Miscanthus, willow, algae, etc.
