Israeli start-up Melodea and its nanocrystalline cellulose (NCC) projects

Three European nanocrystalline cellulose-oriented(NCC) research project grants have been awarded to Israeli start-up company, Melodea according to an Oct. 31, 2013 news item on Azonano,

Israeli startup Melodea Ltd., a leading provider of bio based Nano technology to produce foams from renewable resources, was granted 3 European research grants for 3 groundbreaking projects. Melodea’s technology is based on Nano Crystalline Cellulose (NCC), a primary building block of all living plants that was discovered years ago and was shown to be a most promising raw material for the development of high quality, economically attractive bio-based alternatives to fossil oil polymers.

The Oct. 2013 (?) Melodea news release, which originated the news item, provides more details about the company and the projects,

Melodea Ltd. is developing an economic ally viable industrial process for the extraction of NCC from the sludge of the paper industry, a waste stream produced at millions of tons around the world. The core of the novel technology was developed by the lab of Professor Oded Shoseyov from the Hebrew University of Jerusalem and was licensed exclusively to Melodea.

Moreover, the company develops unique technologies to self-assemble the NCC into ecologically friendly foams for industrial applications.

Melodea Ltd. announced today that it has been awarded above 1,000,000 Euro in 3 projects of the European Union Seventh Framework Program (FP7).

The first project BRIMEE aims to develop insulating boards to attach to the exterior and interior of old buildings walls to improve insulation and reduce energy consumption.

Melodea’s ground breaking NCC foams will be the major constituent of such insulating boards.

The second project NCC-Foam aims to develop commercially-viable, lightweight, rigid foam core materials for sandwich structures for the composite industry.

Today, the common foams for composites are mostly manufactured from a variety of synthetic fossil-oil based polymers that have negative environmental effects compared to NCC based foam which is fully renewable produced from waste stream of the pulp and paper industry.

The third project FLHEA objective is to develop renewable and recyclable food packaging materials based on natural fibers such as flax and hemp. In FLHEA Melodea will produce flax based NCC that will be used as strengthening agent for the novel bio-based packaging materials.”

It is an outstanding achievement for Melodea to be awarded 3 European research grants with exciting European partners. These grants prove the EU commitment to support the development of Nano cellulose applications” said Melodea’s CEO Mr. Yoram Shkedi, “It will also allow Melodea to develop and to commercialize NanoCrystalline Cellulose (NCC) based applications for huge industries such as the construction, composites and food packaging industries”.

I notice they’re calling it nanocrystalline cellulose (NCC) not cellulose nanocrystals (CNC). I wish somebody would pick a name and stick with it as this extra keyboarding gets tiresome. Apparently, Canadians coined the term, NCC while the CNC term originated elsewhere (I don’t know where). Until now, it seemed CNC was becoming the preferred terminology.

If I’m interpreting this part of the news release correctly “… developing an economic ally viable industrial process for the extraction of NCC from the sludge of the paper industry”,, Melodea will either develop a production facility or be instrumental in its creation while working on projects that utilize NCC in industrial applications. All of which leads me to the Canadian stockpile of NCC. As of Aug. 2013, CelluForce, a Canadian NCC production facility, had ceased production due to its stockpile as noted in my Oct. 3, 2013 posting. Hopefully there will be news of some commercialization project(s) that require serious amounts of  NCC from CelluForce.

For those who like to dig deeper, I found websites for the three projects, BRIMEE, NCC Foam, and FLHEA, mentioned in the Melodea news release.

A couple of comments. I notice that Member of Parliament (NDP) Kennedy Stewart,, the Official Opposition Critic for Science and Technology, and member of the Standing Committee on Industry, Science and Technology, is included as a feature speaker this year. Last year (2012), he held an impromptu, after official conference presentation hours sessions on science policy. Good to see that he’s been included in the official programme for 2013. Perhaps next year (2014) will see the Liberal critic for Science and Technology. Ted Hsu as a speaker.

Pierre Lapointe is another speaker whose name caught my attention as he is the President and Chief Executive Officer of FPInnovations, one of the partners behind CelluForce (the other partner is Domtar), the Canadian nanocrystalline cellulose (NCC, aka, cellulose nanocrystals, CNC) initiative. In my Oct. 3, 2013 posting,  I noted that CelluForce had stopped producing NCC as they had a stockpile of the product. Unfortunately, it doesn’t look like there’ll be any mention of the stockpile since Lapointe is on a panel organized by Genome Canada and titled: The complexity of driving the bio-economy: Genomics, Canada’s natural resources and private-public collaborations.

Designing nanocellulose (?) products in Finland; update on Canada’s CelluForce

A VTT Technical Research Centre of Finland Oct. 2, 2013 news release (also on EurekAlert) has announced an initiative which combines design with technical expertise in the production of cellulose- (nanocellulose?) based textile and other products derived from wood waste,

The combination of strong design competence and cutting-edge cellulose-based technologies can result in new commercially successful brands. The aim is for fibre from wood-based biomass to replace both cotton production, which burdens the environment, and polyester production, which consumes oil. A research project launched by VTT Technical Research Centre of Finland, Aalto University and Tampere University of Technology aims to create new business models and ecosystems in Finland through design-driven cellulose products.

The joint research project is called Design Driven Value Chains in the World of Cellulose (DWoC). The objective is to develop cellulose-based products suitable for technical textiles and consumer products. The technology could also find use in the pharmaceutical, food and automotive industries. Another objective is to build a new business ecosystem and promote spin-offs.

Researchers seek to combine Finnish design competence with cutting-edge technological developments to utilise the special characteristics of cellulose to create products that feature the best qualities of materials such as cotton and polyester. Product characteristics achieved by using new manufacturing technologies and nanocellulose as a structural fibre element include recyclability and individual production.

The first tests performed by professor Olli Ilkkala’s team at the Aalto University showed that the self-assembly of cellulose fibrils in wood permits the fibrils to be spun into strong yarn. VTT has developed an industrial process that produces yarn from cellulose fibres without the spinning process. VTT has also developed efficient applications of the foam forming method for manufacturing materials that resemble fabric.

“In the future, combining different methods will enable production of individual fibre structures and textile products, even by using 3D printing technology,” says Professor Ali Harlin from VTT.

Usually the price of a textile product is the key criterion even though produced sustainably. New methods help significantly to shorten the manufacturing chain of existing textile products and bring it closer to consumers to respond to their rapidly changing needs. Projects are currently under way where the objective is to replace wet spinning with extrusion technology. The purpose is to develop fabric manufacturing methods where several stages of weaving and knitting are replaced without losing the key characteristics of the textile, such as the way it hangs.

The VTT news release also provides statistics supporting the notion that cellulose textile products derived from wood waste are more sustainable than those derived from cotton,

Finland’s logging residue to replace environmentally detrimental cotton Cotton textiles account for about 40% of the world’s textile markets, and oil-based polyester for practically the remainder. Cellulose-based fibres make up 6% of the market. Although cotton is durable and comfortable to wear, cotton production is highly water-intensive, and artificial fertilisers and chemical pesticides are often needed to ensure a good crop. The surface area of cotton-growing regions globally equates to the size of Finland.

Approximately 5 million tons of fibre could be manufactured from Finland’s current logging residue (25 million cubic metres/year). This could replace more than 20% of globally produced cotton, at the same time reducing carbon dioxide emissions by 120 million tons, and releasing enough farming land to grow food for 18 million people. Desertification would also decrease by approximately 10 per cent.

I am guessing this initiative is focused on nanocellulose since the news release makes no mention of it but it is highly suggestive that one of the project leads, Olli Ilkkala mentions nanocellulose as part of the research for which he received a major funding award as recently as 2012,. From a Feb. 7, 2012 Aalto University news release announcing the grant for Ikkala’s research,

The European Research Council granted Aalto University’s Academy Professor Olli Ikkala funding in the amount of €2.3 million for research on biomimetic nanomaterials. Ikkala’s group specialises in the self-assembly of macromolecules and how to make use of this process when producing functional materials.

The interests of Ikkala’s group focus on the self-assembled strong and light nanocomposite structures found in nature, such as the nacreous matter underneath seashells and biological fibres resembling silk and nanocellulose. [emphasis mine] Several strong natural materials are built from both strong parallel elements and softening and viscosifying macromolecules. All sizes of structures form to combine opposite properties: strength and viscosity.

The research of the properties of biomimetic nanocomposites is based on finding out the initial materials of self-assembly. Initial material may include, for example, nano platelets, polymers, new forms of carbon, surfactants and nanocellulose.[emphasis mine]

– Cellulose is especially interesting, as it is the most common polymer in the world and it is produced in our renewable forests. In terms of strength, nano-sized cellulose fibres are comparable to metals, which was the very offset of interest in using nanocellulose in the design of strong self-assembled biomimetic materials, Ikkala says. [emphases mine]

Celluforce update

After reading about the Finnish initiative, I stumbled across an interesting little article on the Celluforce website about the current state of NCC (nanocrystalline cellulose aka CNC [cellulose nanocrystals]) production, Canada’s claim to fame in the nanocellulose world. From an August 2013 Natural Resources Canada, Canadian Forest Service, Spotlight series article,

The pilot plant, located at the Domtar pulp and paper mill in Windsor, Quebec, is a joint venture between Domtar and FPInnnovations called CelluForce. The plant, which began operations in January 2012, has since successfully demonstrated its capacity to produce NCC on a continuous basis, thus enabling a sufficient inventory of NCC to be collected for product development and testing. Operations at the pilot plant are temporarily on hold while CelluForce evaluates the potential markets for various NCC applications with its stockpiled material. [emphasis mine]

When the Celluforce Windsor, Québec plant was officially launched in January 2012 the production target was for 1,000 kg (1 metric ton) per day (there’s more in my Jan. 31 2012 posting about the plant’s launch). I’ve never seen anything which confirms they reached their production target, in any event, that seems irrelevant in light of the ‘stockpile’.

I am somewhat puzzled by the Celluforce ‘stockpile’ issue. On the one hand, it seems the planning process didn’t take into account demand for the material and, on the other hand, I’ve had a couple back channel requests from entrepreneurs about gaining access to the material after they were unsuccessful with Celluforce.  Is there not enough demand and/or is Celluforce choosing who or which agencies are going to have access to the material?

ETA Oct. 14, 2013: It took me a while to remember but there was a very interesting comment by Tim Harper (UK-based, emerging technologies consultant [Cientifica]) in Bertrand Marotte’s May 6, 2012 Globe & Mail article (about NCC (from my May 8, 2012 posting offering some commentary about Marotte’s article),

Tim Harper, the CEO of London-based Cientifica, a consultant on advanced technologies, describes the market for NCC as “very much a push, without signs of any pull.”

It would seem the current stockpile confirms Harper’s take on NCC’s market situation. For anyone not familiar with marketing terminology, ‘pull’ means market demand. No one is asking to buy NCC as there are no applications requiring the product, so there is ‘no pull/no market demand’.

Nanocellulose and forest residues at Luleå University of Technology (Sweden)

Swedish scientists have developed a new production technique which scales up the manufacture of cellulose nanfibres and cellulose nanocrystals (CNC, aka nanocrystalline cellulose [NCC]) from waste materials. From the Aug. 30,2013 news item on Nanowerk (Note: A link has been removed),

Luleå University of Technology is the first in Sweden with a new technology that scales up the production of nano-cellulose from forest residues. It may eventually give the forest industry profitable new products, e.g. nano-filters that can clean both the gases, industrial water and even drinking water. Better health and cleaner environment, both nationally and internationally, are some possible outcome

“There is large interest in this from industries, especially because our bionanofilters are expected to be of great importance for the purification of water all around the globe,” says Aji Mathew, Associate Professor at Luleå University of Technology, who leads the EU-funded project, NanoSelect.

The Luleå University of Technology Aug. 28, 2013 news release, which originated the news item, briefly describe the process and the magnitude of the increased production,

On Tuesday [Aug. 27, 2013], researchers at Luleå University of Technology demonstrated before representatives from the Industry and from research institutes how they have managed to scale up the process of manufacture of nano-cellulose of two different residues from the pulp industry. One is from Domsjö in Örnsköldsvik in the form of a fiber product that is grinded down to tiny nano fibers in a special machine. Through this process, the researchers have managed to increase the amount of the previous two kilograms per day to 15 kg per day. Another byproduct is nanocrystals that have been successfully scaled up from 50 to 640 grams / day. The process is possible to scale up and therefore highly interesting for the forest industry.

As noted in the news item, this development is an outcome of the EU- (European Union) funded NanoSelect project, from the Project Details webpage,

NanoSelect aims to design, develop and optimize novel bio-based foams/filters/membranes/adsorbent materials with high and specific selectivity using nanocellulose/nanochitin and combinations thereof for decentralized industrial and domestic water treatment. NanoSelect proposes a novel water purification approach combining the physical filtration process and
the adsorption process exploring the capability of the nanocellulose and/or nanochitin (with or without functionalization) to selectively adsorb, store and desorb contaminants from industrial water and drinking water while passing through a highly porous or permeable membrane.

As the news release notes,

Nano Filter for purification of process water and drinking water is not the only possible product made of nano-cellulose since cellulose has much greater potential.

– Large-scale production of nano-cellulose is necessary to meet a growing interest to use bio-based nanoparticles in a variety of products, says Kristiina Oksman professor at Luleå University of Technology.

Nano filters is today developed at Imperial College, London, in close collaboration with the researchers at Luleå University of Technology.

– We have optimized the process to produce nano filters, we can control the pore size and thus the filter porosity. It’s actually just a piece of paper and the beauty of this piece of paper is that it is stable in water, not like toilet paper that dissolves easily in water, but stable, says Professor Alexander Bismarck at Imperial College.

Nice to hear more about CNC developments.

Crystalline cellulose nanofibers and biomass fuel

Perhaps one day the researchers who work with cellulose at the nanoscale will agree to some kind of terminology. Unfortunately, that day does not seem to be scheduled for the near future as per the latest research from Los Alamos National Laboratory and the Great Lakes Bioenergy Research Center (GLBRC) in the June 19, 2013 news item on ScienceDaily,

Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research from Los Alamos National Laboratory (LANL) and the Great Lakes Bioenergy Research Center (GLBRC). Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic — or non-food — plant derived biomass.

“Cellulose is laid out in plant cell walls as crystalline nanofibers, like steel reinforcements embedded in concrete columns,” says GLBRC’s Shishir Chundawat. “The key to cheaper biofuel production is to unravel these tightly packed nanofibers more efficiently into soluble sugars using fewer enzymes.”

The June 19, 2013 Los Alamos National Laboratory news release, which originated the news item, explains the new technique in more detail,

An article published this week in the Proceedings of the National Academy of Sciences suggests—counter-intuitively—that increased binding of enzymes to cellulose polymers doesn’t always lead to faster breakdown into simple sugars. In fact, Chundawat’s research team found that using novel biomass pretreatments to convert cellulose to a unique crystalline structure called cellulose III reduced native enzyme binding while increasing sugar yields by as much as five times.

The researchers had previously demonstrated that altering the crystal structure of native cellulose to cellulose III accelerates enzymatic deconstruction; however, the recent observation that cellulose III increased sugar yields with reduced levels of bound enzyme was unexpected. To explain this finding, Chundawat and a team of LANL researchers led by Gnana Gnanakaran and Anurag Sethi developed a mechanistic kinetic model indicating that the relationship between enzyme affinity for cellulose and catalytic efficiency is more complex than previously thought.

Cellulose III was found to have a less sticky surface that makes it harder for native enzymes to get stuck non-productively on it, unlike untreated cellulose surfaces. The model further predicts that the enhanced enzyme activity, despite reduced binding, is due to the relative ease with which enzymes are able to pull out individual cellulose III chains from the pretreated nanofiber surface and then break them apart into simple sugars.

“These findings are exciting because they may catalyze future development of novel engineered enzymes that are further tailored for conversion of cellulose III rich pretreated biomass to cheaper fuels and other useful compounds that are currently derived from non-renewable fossil fuels,” says Gnanakaran.

Here’s a link to and a citation for the published paper,

Increased enzyme binding to substrate is not necessary for more efficient cellulose hydrolysis by Dahai Gaoa, Shishir P. S. Chundawat, Anurag Sethic, Venkatesh Balana, S. Gnanakaranc, and Bruce E. Dalea. Published online before print June 19, 2013, doi: 10.1073/pnas.1213426110
PNAS June 19, 2013

There is open access to the article (I’m not sure if this is permanent or temporary).

As I hinted at the beginning of this piece, there are a number of terms used to describe cellulose at the nanoscale. For example, there’s nanocrystalline cellulose (NCC) which is also known as cellulose nanocrystals (CNC); this second term now seems to be preferred. My latest writing on nanocellulose, which seems to be a generic term covering all of the versions cellulose at the nanoscale is in a May 21, 2013 posting about some nanotoxicology studies and in a May 7, 2013 posting about a Saskatchewan-based (Canada) biorefinery (Blue Goose Biorefinery) and its production of CNC.

There are many more here on the topic and, if you’re interested, you may want to try CelluForce, FPInnovations, CNC, and/or NCC, as well as, nanocellulose or cellulose, as blog search terms.

Brazil, Canada, and an innovation, science, and technology forum in Vancouver (Canada)

The Brazil-Canada Chamber of Commerce (BCCC) is presenting, in partnership with Simon Fraser University’s (SFU) Beedie School of Business, an all-morning forum on June 17, 2013. From the SFU Vancouver Events: June 14 – 21, 2013 announcement (Note: Links have been removed),

Brazil-Canada Business, Innovation, Science, and Technology Forum

Time: 8-11:30am

Place: Segal Graduate Business School, 500 Granville St.

Cost: $35-70, register online

Join us for a morning focused on Business Innovation and Science & Tecnology opportunities in the Brazilian economy. The opening speakers, Ambassador Sergio Florencio, Consul General and Dr. Jeremy Hall will provide an overview of the landscape in Brazil. The panel discussion includes industry leaders who have piloted extensive business in Brazil specifically in the agriculture, mining and infrastructure fields: Marcelo Sarkis, Heenan Blaikie; Ray Castelli, Weatherhaven and Rogerio Tippe, Javelin Partners. If you are interested in conducting business in Brazil and would like to understand more about the dynamics of the Brazilian economy and how businesses operate, please register now.

If the event is about business, innovation, science, and technology, it seems curious the only mentions of science and/or technology in the event description are confined to a few of the panelists’ interests in agriculture, mining, and whatever they mean by infrastructure.

Brazil is one of the BRICS (Brazil, Russia,India, China, and South Africa) countries and, from what I understand, this very loose coalition is eager to take a leadership position vis à vis science, technology, and innovation supplanting the dominance of the US, Japan, and the European Union.

In the early 1990s, I wrote a paper about science and technology transfer and noted that Brazil was entering a new period of development after years of the country’s science and technology efforts (scientists) being isolated from the rest of the world in a failed  attempt to create a powerhouse international enterprise.

Some 20 years later, the decision to join the rest of the science and technology world seems to have been successful. Brazil is set to host the 2014 World Cup for soccer (or, as most of the world calls it, football) and the summer Olympics in 2016. (Sports are often correlated with science and technology advances.) I don’t believe any other country has ever attempted to host two such large international sports events within two years of each other. That’s a pretty confident attitude.

There are two areas of science and technology research in Brazil that are of particular interest to me, brain research and the work on cellulose nanocrystals (CNC), also known as, nanocrystalline cellulose (NCC).

While the focus was on Miguel Nicolelis and Duke University (US), the recent announcement of brain-to-brain communication via the Internet featured a research facility in Brazil (from my Mar. 4, 2013 posting),

Miguel Nicolelis, a professor at Duke University, has been making international headlines lately with two brain projects. The first one about implanting a brain chip that allows rats to perceive infrared light was mentioned in my Feb. 15, 2013 posting. The latest project is a brain-to-brain (rats) communication project as per a Feb. 28, 2013 news release on *EurekAlert,

Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart—one in Durham, N.C., and one in Natal, Brazil.

The results of these projects suggest the future potential for linking multiple brains to form what the research team is calling an “organic computer,” which could allow sharing of motor and sensory information among groups of animals. The study was published Feb. 28, 2013, in the journal Scientific Reports.

“Our previous studies with brain-machine interfaces had convinced us that the rat brain was much more plastic than we had previously thought,” said Miguel Nicolelis, M.D., PhD, lead author of the publication and professor of neurobiology at Duke University School of Medicine. “In those experiments, the rat brain was able to adapt easily to accept input from devices outside the body and even learn how to process invisible infrared light generated by an artificial sensor. So, the question we asked was, ‘if the brain could assimilate signals from artificial sensors, could it also assimilate information input from sensors from a different body?’”

One of Nicolelis’s other goals is to have someone with quadriplegia kick the opening ball for the Brazil-hosted 2014 World Cup (Walk Again Project). From my Mar. 16, 2012 posting,

It is the exoskeleton described on the Walk Again Project home page that Nicolelis is hoping will enable a young Brazilian quadriplegic to deliver the opening kick for the 2014 World Cup (soccer/football) in Brazil.

Moving on to the other area of interest, CNC research , which in Canada is discussed in terms of the forestry industry (I’ve blogged about this extensively, the search term NCC should fetch most if not all of my postings on the topic), is taking a different tack in Brazil where the focus is on pineapple and banana fibres. My Mar. 28, 20111 posting (Nanocellulose fibres, pineapples, bananas, and cars) focuses on cellulose and plastic,

Brazilian researchers are working on ways to use nanocellulose fibres from various plants to reinforce plastics in the automotive industry. From the March 28, 2011 news item on Nanowerk,

Study leader Alcides Leão, Ph.D., said the fibers used to reinforce the new plastics may come from delicate fruits like bananas and pineapples, but they are super strong. Some of these so-called nano-cellulose fibers are almost as stiff as Kevlar, the renowned super-strong material used in armor and bulletproof vests. Unlike Kevlar and other traditional plastics, which are made from petroleum or natural gas, nano-cellulose fibers are completely renewable.

My second and, to date, only other posting (June 16, 2011) about the work in Brazil features a transcript of an interview with CNC researcher, Alcides Leão.

Finally, I have a few factoids which I will tie together, loosely, and try to show how they relate to this forum. First, São Paulo, Brazil hosts the world’s second oldest and one of its most important biennial visual arts events. (BTW, the next one, Bienal de São Paulo,  is in 2014.) Second, the recent Council of Canadian Academies assessment, State of Science and Technology in Canada, 2012, stated that Canada rates very highly in six areas, one of those areas being the Visual and Performing Arts. Admittedly Canada’s prominence in the visual and performing is fueled largely by efforts in Québec (as per the assessment), still, one would think there might be some value in trying to include that sector in this  forum and encourage the local visual and performing arts technology industry to make connections with the Brazilian industry.

Finally for those of you who have persisted, here’s the link to buy tickets for the June 17, 2012 forum.

ETA June 21, 2013: The protests in Brazil have attracted worldwide attention and according to a June 21,2013 posting by Dillon Rand on Salon.com there are: 5 signs Brazil’s’ not ready to host the World Cup.

Blue Goose Biorefineries scales up production of cellulose nanocrystals (CNC) and more

I last mentioned Saskatchewan’s (Canada) Blue Goose Biorefineries in a Jan. 22, 2013 posting about its activities with regard to cellulose nanocrystals. I’m a little late to the party but there’s an Apr. 11, 2013 news release on the Advanced Foods and Materials website which notes that Blue Goose Biorefineries’ production of cellulose nanocrystals (CNC also sometimes known as nanocrystalline cellulose, NCC) has been scaled up,

Advanced Foods and Materials (AFM) Canada and Blue Goose Biorefineries Inc. (BGB), are pleased to announce the successful scale up of biorefining technology for the production of high value microcrystalline cellulose (MCC), cellulose nanocrystals (CNC), lignin, and green platform chemicals from flax and hemp straw.

In collaboration with the University of Saskatchewan’s College of Agriculture and Bioresources Bioprocessing Pilot Plant, and POS Bio-Sciences, BGB’s proprietary Renewable Residuals RefiningTM (R3TM) biorefining technology was successfully scaled up to process 100 kg of pulp in a reaction volume of 2500L to produce microcrystalline cellulose and cellulose nanocrystals of high purity, along with lignin and green platform chemicals as by-products. Throughout this process, the technology has shown promising advantages over existing biorefining methods including cost, yield, environmental impact, and flexibility. Necessary process steps demonstrated include biomass preparation, dewatering and washing, reaction mixing and crystalline cellulose washing. The project also successfully demonstrated the spray drying of the cellulose crystals at POS Bio-Sciences.

It’s exciting to hear that there might be more production of CNC in Canada, as well as, microcrystalline cellulose, lignin, and other by-products,. It seems where CNC is concerned that demand exceeds supply (I get the occasional query from someone trying to find a supplier).

I have more information about Advanced Foods and Materials Canada in my Jan. 22, 2013 posting. As well, here are links to the POS Bio-Sciences website and more information about the University of Saskatchewan’s Bioprocessing Pilot Plant.

ETA May 7, 2013 4:30 pm PDT: Dr. Bernard Laarveld of Blue Goose Biorefineries (BGB) very kindly noted this in an email to me today,

… we are now planning to develop a pilot plant for the production of NCC (aka CNC) and MCC and are raising the funding. This development through BGB is more driven from the private sector in partnership with Advanced Food Materials Canada.  We intend to process about 500 kg  of flax or hemp straw per day, and this would generate about 250 kg per day of crystalline cellulose. BGB has an advantage through low cost of production.

Very exciting news and I wish the Dr. Laarveld and the folks at BGB all the best.

Solar cells made even more leaflike with inclusion of nanocellulose fibers

Researchers at the US Georgia  Institute of Technology (Georgia Tech)  and Purdue University (Indiana) have used cellulose nanocrystals (CNC), which is also known as nanocrystalline cellulose (NCC), to create solar cells that have greater efficiency and can be recycled. From the Mar. 26, 2013 news item on Nanowerk,

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle.

The Georgia Tech Mar. 25, 2013 news release, which originated the news item,

The researchers report that the organic solar cells reach a power conversion efficiency of 2.7 percent, an unprecedented figure for cells on substrates derived from renewable raw materials. The CNC substrates on which the solar cells are fabricated are optically transparent, enabling light to pass through them before being absorbed by a very thin layer of an organic semiconductor. During the recycling process, the solar cells are simply immersed in water at room temperature. Within only minutes, the CNC substrate dissolves and the solar cell can be separated easily into its major components.

Georgia Tech College of Engineering Professor Bernard Kippelen led the study and says his team’s project opens the door for a truly recyclable, sustainable and renewable solar cell technology.

“The development and performance of organic substrates in solar technology continues to improve, providing engineers with a good indication of future applications,” said Kippelen, who is also the director of Georgia Tech’s Center for Organic Photonics and Electronics (COPE). “But organic solar cells must be recyclable. Otherwise we are simply solving one problem, less dependence on fossil fuels, while creating another, a technology that produces energy from renewable sources but is not disposable at the end of its lifecycle.”

To date, organic solar cells have been typically fabricated on glass or plastic. Neither is easily recyclable, and petroleum-based substrates are not very eco-friendly. For instance, if cells fabricated on glass were to break during manufacturing or installation, the useless materials would be difficult to dispose of. Paper substrates are better for the environment, but have shown limited performance because of high surface roughness or porosity. However, cellulose nanomaterials made from wood are green, renewable and sustainable. The substrates have a low surface roughness of only about two nanometers.

“Our next steps will be to work toward improving the power conversion efficiency over 10 percent, levels similar to solar cells fabricated on glass or petroleum-based substrates,” said Kippelen. The group plans to achieve this by optimizing the optical properties of the solar cell’s electrode.

The news release also notes the impact that using cellulose nanomaterials could have economically,

There’s also another positive impact of using natural products to create cellulose nanomaterials. The nation’s forest product industry projects that tens of millions of tons of them could be produced once large-scale production begins, potentially in the next five years.

One might almost  suspect that the forest products industry is experiencing financial difficulty.

The researchers’ paper was published by Scientific Reports, an open access journal from the Nature Publishing Group,

In closing, the news release notes that a provisional patent has been filed at the US Patent Office.And one final note, I have previously commented on how confusing the reported power conversion rates are. You’ll find a recent comment in my Mar. 8, 2013 posting about Ted Sargent’s work with colloidal quantum dots and solar cells.

Waterloo Institute of Nanotechnology/EcoSynthetix industrial partnership and an interlaced relationship

The EcoSynthetix and Waterloo Institute for Nanotechnology partnership announced today (Mar. 13, 2013) is an example of how tightly interlaced the relationships between academic institutions and their graduates’ start-up companies can be. A Mar. 13, 2013 news item on Nanowerk describes the partnership,

EcoSynthetix Inc. and the Waterloo Institute for Nanotechnology at the University of Waterloo have joined forces through an industrial partnership to collaborate on new applications for EcoSynthetix’ EcoSphere® technology. The five-year agreement will be jointly funded through an EcoSynthetix and NSERC (National Sciences and Engineering Research Council) Collaborative Research and Development Grant. The project matches the scientific expertise from the University of Waterloo in macromolecular science with the sustainability benefits of EcoSphere® bio-based nanoparticles which are based on green chemistry. The goal of the project is to broaden the scientific knowledge base of the EcoSphere® technology to support its introduction into new application areas.

The Mar. 13, 2013 EcoSynthetix news release, which originated the news item, mentions the relationship in passing while extolling the virtues of the partnership,

“As a global centre of excellence for nanotechnology research, this project represents a great opportunity for our institute, faculty and students at the University, to collaborate with a local innovator to further our understanding of the technology and its potential applications,” said Dr. Arthur J. Carty, Executive Director of the Waterloo Institute for Nanotechnology (“WIN”) and an independent director of the board of EcoSynthetix. [emphasis mine] “Nanotechnology is a leading-edge, enabling technology that holds the promise of a lasting economic benefit for jobs and investment in the materials, energy and healthcare sectors. EcoSynthetix’s innovative nanotechnology has the potential to impact a wide-array of markets that would benefit from a sustainable alternative to petroleum-based products.”

“This ECO-WIN collaboration involves four professors and eight graduate students at the Waterloo Institute for Nanotechnology and is a great example of how industry and universities can work together to advance an exciting new area of science to benefit the community,” said Dr. Steven Bloembergen, Executive Vice President, Technology of EcoSynthetix. “Our EcoSphere® technology is already commercial and providing sustainable benefits in three separate markets today. Our team’s primary focus at this stage is near-term product development and product enhancements of carbohydrate-based biopolymers. By working with the Institute of Nanotechnology to deepen our understanding of the basic science, we can identify new future applications that could benefit from our sustainable biobased materials.”

The EcoSphere® technology is being commercially utilized as biobased latex products providing alternatives to petroleum-based binders in the coated paper and paperboard market. [emphasis mine] The goal of this project is to generate a greater understanding of the properties of EcoSphere® biolatex® binders by establishing a knowledge base that could enable tailor-made novel particles with the desired properties for a given application. The project team will be chemically modifying the nanoparticles and then characterizing how the properties of the novel particles are affected by these changes.

I don’t understand what “independent director” means in this context. Is the term meant to suggest that it’s a coincidence Carty is WIN’s executive director and a member of the EcoSynthetix board? Or, does it mean that he’s not employed by the company? If any readers care to clarify the matter, please do leave a comment. In any event, the EcoSynthetix timeline suggests the company has a close relationship with the University of Waterloo as it was founded in 1996 by graduates  (from the company’s About Us History Timeline webpage),

EcosynthetixTimeline

As for the product line which birthed this partnership, there’s a disappointing lack of technical detail about Ecosphere biolatex binders. Here’s the best I can find on the company website (from the Ecosphere Biolatex Binders Performance page),

The smaller particle size characteristic of biolatex binders results in increased binder strength and performance. In coated paper, it provides improved aesthetics; a rich, bright finish; enhanced open structure and excellent printability across all grades.

I wonder if some of this new work will be focused on ways to use CNC (cellulose nanocrytals or NCC, nanocrystalline cellulose) in addition to the company’s previously developed “bio-based nanoparticles”  to enhance the product which, as I highlighted earlier, sells to the “coated paper and paperboard market.” From the CelluForce (the CNC/NCC production plant in Quebec) Applications page,

NCC’s properties and many potential forms enable many uses, including:

  • Biocomposites for bone replacement and tooth repair
  • Pharmaceuticals and drug delivery
  • Additives for foods and cosmetics
  • Improved paper and building products
  • Advanced or “intelligent” packaging
  • High-strength spun fibres and textiles
  • Additives for coatings, paints, lacquers and adhesives
  • Reinforced polymers and innovative bioplastics
  • Advanced reinforced composite materials
  • Recyclable interior and structural components for the transportation industry
  • Aerospace and transportation structures
  • Iridescent and protective films
  • Films for optical switching
  • Pigments and inks
  • Electronic paper printers
  • Innovative coatings and new fillers for papermaking

Since I’m already speculating, I will note I’ve had a couple of requests for information on how to access NCC/CNC from entrepreneurs who’ve not been successful at obtaining the material from the few existing production plants such as CelluForce and the one in the US. It seems only academics can get access.

One last comment about this ‘partnership’, I’d dearly love to know what relationships, if any exist, between the proponents and the NSERC committee which approved the funding.

Interestingly, Carty is the chair for the recently convened expert panel for the Council of Canadian Academies’ The State of Canada’s Science Culture assessment, as per my Dec. 19, 2012 post about the announcement of his appointment. This latest development casts a new light on the panel (my Feb. 22, 2013 post notes my reaction to the expert panel’s membership) and the meaning of science culture in Canada.

Sanofi BioGENEius Challenge Canada celebrates 20 years

The first time (May 11, 2012 posting) I wrote about the Sanofi BioGENEius Challenge Canada (SBCC) competition was when Janelle Tam was recognized as the 2012 national winner for her work with nanocrystalline cellulose (NCC) or, as it is sometimes known, cellulose nanocrystals (CNC).  As I noted then,

For anyone who’s curious about Sanofi, it’s a French multinational pharmaceutical company headquartered in Paris, France. I found the Wikipedia essay a little more informative than the Sanofi company website .

Justifiably proud not only of Tam and other 2012 winners, SBCC has sent out a news release enumerating the many triumphs and benefits associated with this competition. From the SBCC Feb.20, 2012 news release,

Unexpected bonus prizes from a high school bioscience competition, mentored by some of Canada’s top research experts, range from six-figure scholarships, valuable networks and commercial patents to peer-reviewed journal citations, global publicity, international conference invitations and more, former teen participants say.

But the reward cited most often by alumni of the “Sanofi BioGENEius Challenge Canada” (SBCC), this year marking its 20th annual competition, is the eye-opening experience of watching their inventive ideas succeed and being encouraged in a professional lab, creating in many a career-shaping passion for science.

“That’s a benefit shared throughout Canada’s economy, which has a growing, $86 billion biotechnology sector, as well as with people worldwide,” says Jeff Graham, Chair of the Board at the Toronto-based Bioscience Education Canada, which manages the SBCC program.

“This program has been ‘infecting’ teens with what one mentor calls the ‘research virus’ and inspiring bioscience careers since 1994. And with hundreds of dedicated partner organizations and mentors nation-wide, we are extremely proud of the success achieved so far as we mark the 20th annual SBCC.

The competition’s latest surprise bonus prize winners are 2012 national competitors Jeanny Yao, 18, and Miranda Wang, 19 of Vancouver, both now in first year at universities in Toronto and Montreal respectively.  The pair will spend Feb. 27 in Long Beach California, invited by organizers of the prestigious TED 2013 conference to tell the world’s science elite how they identified a species of bacteria from the Fraser River’s muddy banks that helps decompose plastic.

Their BC regional SBCC-winning project came to public attention last May in a front page story by the Vancouver Sun (http://bit.ly/XrsaB9)  as the duo were packing to attend SBCC’s national finals in Ottawa.  In the white marble halls of National Research Council of Canada headquarters — the country’s science temple — SBCC’s high-level final judging panel recognised Jeanny and Miranda’s project with a special prize for the “greatest commercial potential.”  (The girls have since approached firms in BC and Ontario on commercialisation ideas.)

They were invited last summer to present their project again at TED@Vancouver (http://bit.ly/X5PRAF), part of a “worldwide talent search,” and were among a handful picked from 293 entrants to reprise their presentation in California.

TED is widely considered the world’s marquee annual science show-and-tell.  And sharing a stage with fellow speakers like U2’s lead singer Bono and PayPal Founder Peter Theil is a five exclamation mark adventure for a couple of university frosh.

“We are extremely excited about this opportunity…!! We couldn’t have done this without your help!!!” Miranda wrote, announcing the news to SBCC’s Vancouver coordinators, LifeSciences BC.  (For more on Jeanny and Miranda at TED: http://bit.ly/WRAs45).

According to the news release some 4500 Canadian teenagers have participated in the competition since 1994. There was a survey of 375 participants, from the news release,

In a survey of 375 past participants by Bioscience Education Canada [BEC], which runs SBCC, 84% said their participation helped determine their field of study or career plan; 74% were pursuing biotechnology-related education or professions, with 12.5% undecided.  Some 55% were current university students, 24% planned to apply after high school, and 21% were post-secondary graduates now in the workforce.  Nearly 60% of respondents were female and 79% had or have bursaries and/or scholarships.

Typical of comments teens relayed with the survey replies, from Brooke Drover of Vernon River, PEI: “It was amazing. So unbelievably stressful, but when my team came second place I could hardly breathe. It was the best feeling in the world knowing that I didn’t just play a sport and win a trophy. I helped the scientific community.”

“Thanks to hundreds of top scientist mentors who have shared their expertise and lab space with the student competitors, we’ve discovered and nurtured incredible talent in high schools and CEGEP classrooms nation-wide,” says Rick Levick, Executive Director of BEC and head of the national competition since its inception,

“The mentors are the unsung heroes of the SBCC program. They often bring out a passion for science and talent for research in kids who didn’t know they had any.”

While I do have some questions about the survey (when was it administered? how was it administered? why 375? etc.), I’m letting them go in appreciation of the participants’ extraordinary accomplishments, from the news release,

Ottawa

Maria Merziotis, $5,000 first place winner in the national 2008 SBCC, found her prize included an academic fast track.  At 21, when those her age at university typically complete an undergrad degree, she’s finishing second year at the University of Ottawa’s medical school, with papers about her flu-related research in preparation for academic publication.

And, just seven years after he first impressed SBCC’s august panel of national judges as a Grade 11 student, Ottawa’s James MacLeod, now 23, is completing a Queen’s University master’s degree in pathology and molecular medicine and applying for early acceptance into the department’s PhD program.

Both credit SBCC with helping them reach medical career doors unusually soon.  Says Maria: “The SBCC competition is the main reason I stand where I am today.  It allowed me to explore the field of research, and through the doors it opened, gained me early acceptance into medical school.”

Saskatchewan

Says Rui Song of Saskatoon, who in Grade 9, age 14 (a veteran of Saskatchewan’s unique SBCC program for kids in Grades 7 and 8) prevailed over much older teens to win the #1 national award in 2010: “Before the SBCC, I hadn’t even considered being a researcher. I now hope to continue my research journey in university and in my career to continue creating beneficial change in the world.”

Her 2010 work to genetically fingerprint a lentil crop-killing fungus left the expert national judges “astonished.”  She also placed 2nd in last year’s national competition, accepted an offer to spend last summer doing research at Harvard, and today, in Grade 12, is weighing full-time university offers.

Southwestern Ontario

The 2012 top national winner, Janelle Tam of Waterloo, says “SBCC was a huge part of why I started laboratory research at the university in high school, which was instrumental in my decision that I want to be a professor.”

Janelle, completing Grade 12 with studies at Princeton University ahead this fall, detailed the anti-ageing potential of a nano compound found in wood pulp, capturing media attention in at least 36 countries (http://bit.ly/XduBJd), including a social media blog by then-Ontario Premier Dalton McGuinty (http://bit.ly/THiq7P).  Last summer in Québec she detailed her findings to staff and researchers of CelluForce’s, Domtar Corp. and FPInnovations — Canadian firms leading the commercial development of nanocrystalline cellulose.

Newfoundland

At 17, Sarai Hamodat of St John’s, Newfoundland, entered a prize-winning SBCC project  showing that a traditional Asian oil remedy could ease the suffering of asthma patients, a project inspired by her hope of helping her asthmatic uncle.

Says Sarai, now 23 and a medical resident in pharmacology at the Queen Elizabeth II Health Sciences Centre in Halifax: “SBCC was my first real introduction to what the world of science has to offer.”

British Columbia

Taneille Johnson entered the competition in 2009 from Fort St. John (pop. 22,000) near the Alberta border in northern BC.  At 16, she lived alone for a summer to work with a University of Calgary mentor in a quest to decipher DNA mutations that may lie behind a rare disorder which causes early onset aging and progressive bone marrow failure.

Taneille, the first student from northern BC to enter the regional event, won it in 2010 and placed third overall at the national finals in Ottawa.  Now 20, she’s a second year BSc student of immunology at McGill University, Montreal, with a goal of medical school studies at the University of British Columbia.

“Not many first year university science students can approach their professor and show them the amount of lab experience I had from the SBCC,” she says, adding “I really cannot overstate how unique the SBCC experience is for high school students.”

Greater Toronto

A year after his first place national win in the 2011 SBCC, Toronto’s Marshall Zhang faced a tough decision: offers from three of the world’s most prestigious Ivy League universities — Yale, Harvard and Princeton.

“The SBCC changed the course of my life,” says Marshall, now a Harvard freshman, who at age 16, and mentored at the Hospital for Sick Kids, used a powerful supercomputer cluster to create a potential new treatment for cystic fibrosis.

On CBC’s “The Nature of Things,” host Dr. David Suzuki cited Marshall and his ideas as an example of the marvels of uninhibited teenage thinking.  CF patients and their parents from across Canada and elsewhere wrote or called out of the blue to congratulate and thank Marshall for his efforts on their behalf.  He was in Grade 11.

“I’d never met a CF patient before then,” he says, adding that the most memorable part of the entire adventure was realizing the real impact his research could have on people.

Manitoba

At 17, Ted Paranjothy of Winnipeg, inspired by a memory from five years old of a friend who died from leukemia, invested 3,000 research hours over two years after school with a mentor at the University of Manitoba, developing innovative ideas for cancer treatment.  Ted’s framework for an anti-cancer agent able to kill human cancer cells without harming healthy ones is an innovation on which he now holds a patent.

His Grade 12 project earned a triple crown of high school biotech science: a first place sweep of the 2007 SBCC regional and national competitions, as well as the Sanofi-sponsored International BioGENEius Challenge — the only Canadian to achieve that distinction so far.  The three first prize cheques totaled $15,000.

Later awarded some $150,000 in scholarships from other sources, Ted continued work with his distinguished mentor, Dr. Marek Los, and had three papers in peer-reviewed journals by the end of first year at UofM.  Now 22, Ted is an independent researcher in cell science at UofM.  He credits SBCC with enabling his university graduate-level research while still in high school, and says it “inspired me to pursue a career in biomedical research.”

Quebec

In 2011, a trio of Montreal CEGEP students entered the national SBCC with their new sorbet for vegetarians, having discovered a substitute for animal-based gelatine normally found in the frozen dessert.  They won 2nd prize overall, a special award for that year’s project with the greatest commercial potential, and a lot of public attention, which helped create connections with several patent lawyers.

Today, all three are at universities studying science.  “The SBCC definitely pushed to me to explore research opportunities in medicine,” says one team member, Simon Leclerc, adding that feedback from top scientists who evaluated their project and the experience gained was “inestimable… The SBCC is of great help for young, otherwise non-connected students to push their projects forward.”

Brava! Bravo!

Applications for the 2013 competition have been closed since November 2012 but there is a listing of the times and dates for the regional and national 2013 competitions. Although it’s unclear to me whether or not the public is invited to attend, you can get more details here.
