Integrated Human Practices
![](https://static.igem.org/mediawiki/2017/9/90/Dalimprove.jpg)
Despite the unequivocal evidence for climate change, a recent poll commissioned by the Ontario Science Center (Canada, 2017) found that 47% of the public (up from 40% last year) agreed that “the science behind global warming is still unclear.” A quote by the chief executive officer of the Ontario Science Center summarizes the problem that arises from this statistic: "If you think that climate change is one of the main issues that we face as a society, and almost half of us think that the science is still unclear when there's a pretty broad scientific consensus about it, this affects the chances that we have to act in a unified way about it." While our team was taken aback by the statistic, we were not entirely surprised considering there are many prominent public figures such as politicians and celebrities who deny climate changing is occurring. How, as a society, we move forward to address complex scientific issues is going to become increasingly more important in the future. On a more positive note, despite 31% of respondents agreeing that “because scientific ideas are fluid and subject to change they can’t be trusted,” 79% agreed that they are comfortable “knowing that scientific answers may not be definitive”, and 82% said they “would like to know more about science and how it affects our world”. Our project by no means is the only answer to stopping or slowing climate change, but it will help reduce the environmental impact and waste of the paper and pulp industries, once we engineer E. coli to degrade cellulose into glucose. With the knowledge that the public wants to learn about science and with the understanding that in order to address climate change everyone needs to be on board, we developed our integrated human practices strategy. There are four ways in which we integrated human practices into our experimental design: talking with experts, discussing safety, researching other Canadian biofuel companies, and presenting our project to various audiences. In addition, we developed an extensive outreach program to establish an open communication platform between the public and scientists (click here to few our engagement activities). We hope to foster curiosity, answer questions and concerns, and get more people talking about science!

Safety
After speaking with Scott Doncaster from the fermentation company, BioVectra, it was clear that there were a few safety aspects to consider if our project were to make it to the bioreactor stage. In this section, we hope to address two questions:- is our design safe?
- What are the major concerns for companies?
How We Fit In: Researching Companies
There are five major biofuel companies in Canada each doing something slightly different. Here are summaries of those five major companies. Iogen Corporation is one of the longest withstanding biofuel companies in Canada. They were founded in 1975, in East Ottawa, and have been producing cellulosic ethanol since 2004. They focus on plant fiber and enzymatic hydrolysis in order to produce a dilute ethanol stream, which is further concentrated to commercial-grade fuel. The St. Clair ethanol plant from Suncor Company, has been producing 400 million tons of biofuel per year. This facility in the Sarnia-Lambton region has been running since 2006, and it has been named the largest ethanol plant in Canada. Suncor uses corn fiber to produce their strain of ethanol. They have partnered with Petro-Canada to blend their ethanol with Petro- Canada’s gasoline. Although this does not diminish greenhouse gases completely, the use of blended ethanol-gasoline fuel has been reported to reduce CO 2 emissions by up to 300,000 tons per year. Evoleum Biofuel is located in Saint-Jean- sur-Richelieu, Quebec. It is a major producer for biofuels from second generation raw material. At Evoleum, the second generation materials used are exclusively vegetable oil. They have created 95% biodegradable biodiesel, that produces no greenhouse gas emission. Since 2010, the use of the recycled materials for biofuel in Montreal, from Evoleum, showed a decrease of 4.8 cents a liter on biodiesel. In Nova Scotia, the CelluFuel Company uses low-value wood fiber to convert into renewable diesel. They receive their wood fiber from Freeman’s Lumber in Greenfield, Nova Scotia. The wood fiber undergoes a series of catalytic induced depolymerisation’s to produce the renewable diesel. Today, CelluFuel is currently in its demonstration phase, and once they have successfully completed this project they will begin producing commercial-grade fuel. Another upcoming company for biofuel production in Canada, is Woodland Biofuel, Incorporation. They are currently in their demonstrative phase with their start up plant located in Sarnia, Ontario. Woodland is interested in cellulosic ethanol production, using agriculture and forestry waste. The President, Greg Nuttal, states that it will be one of the lowest fuel productive costs, not just for ethanol but other fuel industries, including gasoline. He suggests the company will produce 200 million gallons per year. As of now, this company is looking into another plant location in Merritt, British Columbia. Clearly biofuel production is a popular industry sector with each of the aforementioned companies carving out a particular niche for themselves. We believe that in this competitive field, our project could have potential to hold its own. Firstly, our project would utilize cellulose-containing waste from various industries and therefore our feedstock substrate would not be limited to one particular area. This could be important in the future when certain resources become scarce. As long as our substrate contained cellulose we could convert it! Secondly, these companies still seem dependent on chemicals, water, or heat to aid in the production process. Our project would utilize the enzymatic capabilities of microorganisms to convert cellulose into glucose. Furthermore, we could modify this process to enhance for production, for example, by modifying our organism. While we are a while away from making a name for ourselves in the Canadian biofuel game, we have found our own niche within the market.Practising Science Communication
We did not want our research to only reach the eyes and ears of those partaking in iGEM, therefore we practised tailoring our project description for different members of the community. When writing these “elevator pitches” we were surprised to discover how difficult it can be to modify language to fit the audience. Children in particular were a difficult group to target as they could have varying degrees of understanding and varying interest levels. Writing pitches for discussions with companies and financial supporters was easier because the objective of the talk was clear: how can we demonstrate to companies that we are worth investing in? We ended up using many of these “elevator pitches” in our outreach events as well as when talking to potential financial supporters. Here are a few examples of those pitches. Media: Story Oriented The International Genetically Engineered Machine (iGEM) is a global initiative that aims to get students tackling real world problems using synthetic biology. Competitors get to choose which problem to address. We wanted to focus our project on something that was close to home, yet could also have a big impact. One of our first ideas was to develop an easier way to make biofuel. While this idea is not particularly novel, we managed to put our own spin on it. We’re creating biofuel from forestry waste. Why? The forestry industry is a major source of cellulose waste. Cellulose can actually be converted into ethanol -- which is a potent biofuel. There are already ways to convert cellulose into ethanol but they are not exactly efficient. After a lot of research, we think we have found a way to make the conversion process more efficient. Lots of animals eat wood and they have to digest it somehow, right? Most animals can’t do this themselves and instead rely on bacterial enzymes found in their gut to help them. One of these animals is the porcupine. We decided to take the cellulose-degrading enzymes from one of the porcupine gut bacteria to see if we could make it work for us. In the future we are going to try to streamline the process so that we can make large amounts of ethanol in an efficient, waste-free way. We’ve been working throughout the whole summer to make this happen, and are now getting ready to present our research at the global iGEM conference in Boston. In front of a global audience we will be the only team representing Atlantic Canada! The message: Team of undergraduate students participating in an international competition in which they are developing a novel biofuel production system. Technical difficulty: Limited scientific jargon, accessible to a general audience. Corporations: Economically Oriented iGEM is a global initiative encouraging students to use synthetic biology to solve real world problems. Our project tackles two major problems facing Atlantic Canada: sustainable fuel and forestry waste. We’re using synthetic biology to convert cellulose waste from the forestry industry into ethanol, a potent biofuel. Our team is comprised of eager and passionate undergraduate students and graduate mentors from all disciplines. iGEM is currently the only opportunity in Atlantic Canada for students to obtain hands on synthetic biology research experience. We’ll be traveling to Boston in November to represent Atlantic Canada at the 2017 iGEM jamboree where we will be presenting our findings to researchers, corporations, and students from around the world. The message: Our project tackles two issues for Atlantic Canada and could offer an economically viable solution. Furthermore, students part of iGEM have training that is not found elsewhere in the province. Technical difficulty: Limited scientific jargon. Very short and concise. A 6-Year Old: Fun Oriented Within your stomach are millions of very tiny bugs called bacteria that help you out in all sorts of ways such as breaking down the food you eat. It is not just people who have these helpful bacteria, lots of other animals do as well. For example, the spiky animal called the porcupine has bacteria in its stomach which help it break down the wood it likes to eat. We wanted to see if we could get the parts of the bacteria responsible for breaking down the wood to function outside of the porcupine stomach. That way we could break down left over wood into helpful things such as fuel. The message: We are attempting to harness the different abilities of the bacteria found on and in the body. Technical difficulty: No scientific jargon. Not focused too much on our project. As communication is the major theme to our outreach efforts (click here to visit the outreach page), it was imperative that we practiced and attempted to better our own communication habits. Writing these elevator pitches served as an important exercise in learning how best to convey our project.
