Does cellulosic ethanol from sawdust wood is possible?

Gas, ethanol, petrol, Diesel, are all different kind of fuel that can be put into our cars, but what is the difference between them? One major difference that ethanol has, is that it is based on corn and other material that sugar can be taken out of. Its particularity is that scientist can almost find cellulosic ethanol in every material. The mainly ingredients to create ethanol is the fermentation of sugar. Basically, the creation of ethanol can be based on wood or even “chips of wood” (Kevin, Bullis, p1). The only problem scientist are facing, is that the amount of ethanol produced (39.9 mg L-1) against the amount of wood (10 kg) is too small for now to be considered as a good investment (J. N. Nwakaire, S. L. Ezeoha, B. O. Ugwuishiwu, p5 ).
In the article, Production of cellulosic ethanol from wood sawdust, it shows an analysis of the experience of producing sawdust wood and converting wood into ethanol. Their conclusion to this experience is that extracting ethanol still needs improvement, but this method could be a good investment. There is tons of lost wood from paper industries, wood industries and even from our recycle bins. The experience was done to see how much of pure ethanol could be extract from sawdust wood, because it would be a better way to create ethanol than corn. Sawdust of wood also reduces the percent of carbon dioxide into the air more than corn ethanol.
The article from Kevin Bullis, Making Ethanol from Wood Chips, talks about the possible investment of ethanol into the market. Many companies would be interested of having a “cheaper” ethanol than from corn. It is also exposing the problem face with corn ethanol, since we also use corn in our alimentation ,the amount of corn for ethanol is reduce but not sawdust .It is only garbage and waste from companies. An announcement at the beginning of the article was telling that a company of “chips” wood ethanol got an investment of $30 million dollar to explore more in this domain.
The last article mentions experiences done, but the author does not speak into specific terms. That is why the article, by Kevin Bullis, is more generic than the other. It is more open to a general public comprehension than the other, which clearly compares values and explains all the steps of the creation of cellulosic ethanol. These two articles are talking about the same subject, but one is explaining and getting more into details than the other. If we consider the year of post from both articles; 2013, and 2006 for the article by Kevin Bullis, the article by the University of Nigeria may be more accurate.

This article is relevant with my topic because it is part of the environment issues (global warming is causes by carbon dioxide and other facts but this articles gets into deep and we can clearly understand the challenge it has to be greener. This article is a reliable source since it is a peer-reviewed article, so this means it has been modify or approved by a specialist in the subject.
Bullis, Kevin. “Making Ethanol from Wood Chips.”M.I.T technology Review. N.p. 16 Nov. 2006. Web. 6 November 2013.
I decided to compare these two articles, because I wanted to see the differences between what they are saying on an article that is not peer-reviewed, and on a peer-reviewed one. This article is also using more general terms and talks about the general project, not on a specific case. This article is sort of reliable because the author is only writing for the pleasure of entertaining, and to inform people of new energy on market but he have written more than thousands of articles on energetic subject and he has dedicated his life to inform people with new technologies. He is not a specialist or has been in contact with specialist, he is only relying on facts. However, his information’s on cellulosic ethanol, if we compare them to the other article that is a reliable one, are reliable and accurate.
