Good lignin, bad lignin: Florida researchers use plant waste to create lignin nanotubes while researchers in British Columbia develop trees with less lignin

An April 4, 2014 news item on Azonano describes some nanotube research at the University of Florida that reaches past carbon to a new kind of nanotube,

Researchers with the University of Florida’s [UF] Institute of Food and Agricultural Sciences took what some would consider garbage and made a remarkable scientific tool, one that could someday help to correct genetic disorders or treat cancer without chemotherapy’s nasty side effects.

Wilfred Vermerris, an associate professor in UF’s department of microbiology and cell science, and Elena Ten, a postdoctoral research associate, created from plant waste a novel nanotube, one that is much more flexible than rigid carbon nanotubes currently used. The researchers say the lignin nanotubes – about 500 times smaller than a human eyelash – can deliver DNA directly into the nucleus of human cells in tissue culture, where this DNA could then correct genetic conditions. Experiments with DNA injection are currently being done with carbon nanotubes, as well.

“That was a surprising result,” Vermerris said. “If you can do this in actual human beings you could fix defective genes that cause disease symptoms and replace them with functional DNA delivered with these nanotubes.”

An April 3, 2014 University of Florida’s Institute of Food and Agricultural Sciences news release, which originated the news item, describes the lignin nanotubes (LNTs) and future applications in more detail,

The nanotube is made up of lignin from plant material obtained from a UF biofuel pilot facility in Perry, Fla. Lignin is an integral part of the secondary cell walls of plants and enables water movement from the roots to the leaves, but it is not used to make biofuels and would otherwise be burned to generate heat or electricity at the biofuel plant. The lignin nanotubes can be made from a variety of plant residues, including sorghum, poplar, loblolly pine and sugar cane. [emphasis mine]

The researchers first tested to see if the nanotubes were toxic to human cells and were surprised to find that they were less so than carbon nanotubes. Thus, they could deliver a higher dose of medicine to the human cell tissue.  Then they researched if the nanotubes could deliver plasmid DNA to the same cells and that was successful, too. A plasmid is a small DNA molecule that is physically separate from, and can replicate independently of, chromosomal DNA within a cell.

“It’s not a very smooth road because we had to try different experiments to confirm the results,” Ten said. “But it was very fruitful.”

In cases of genetic disorders, the nanotube would be loaded with a functioning copy of a gene, and injected into the body, where it would target the affected tissue, which then makes the missing protein and corrects the genetic disorder.

Although Vermerris cautioned that treatment in humans is many years away, among the conditions that these gene-carrying nanotubes could correct include cystic fibrosis and muscular dystrophy. But, he added, that patients would have to take the corrective DNA via nanotubes on a continuing basis.

Another application under consideration is to use the lignin nanotubes for the delivery of chemotherapy drugs in cancer patients. The nanotubes would ensure the drugs only get to the tumor without affecting healthy tissues.

Vermerris said they created different types of nanotubes, depending on the experiment. They could also adapt nanotubes to a patient’s specific needs, a process called customization.

“You can think about it as a chest of drawers and, depending on the application, you open one drawer or use materials from a different drawer to get things just right for your specific application,” he said.  “It’s not very difficult to do the customization.”

The next step in the research process is for Vermerris and Ten to begin experiments on mice. They are in the application process for those experiments, which would take several years to complete.  If those are successful, permits would need to be obtained for their medical school colleagues to conduct research on human patients, with Vermerris and Ten providing the nanotubes for that research.

“We are a long way from that point,” Vermerris said. “That’s the optimistic long-term trajectory.”

I hope they have good luck with this work. I have emphasized the plant waste the University of Florida scientists studied due to the inclusion of poplar, which is featured in the University of British Columbia research work also being mentioned in this post.

Getting back to Florida for a moment, here’s a link to and a citation for the paper,

Lignin Nanotubes As Vehicles for Gene Delivery into Human Cells by Elena Ten, Chen Ling, Yuan Wang, Arun Srivastava, Luisa Amelia Dempere, and Wilfred Vermerris. Biomacromolecules, 2014, 15 (1), pp 327–338 DOI: 10.1021/bm401555p Publication Date (Web): December 5, 2013

This is an open access paper.

Meanwhile, researchers at the University of British Columbia (UBC) are trying to limit the amount of lignin in trees (specifically poplars, which are not mentioned in this excerpt but in the next). From an April 3, 2014 UBC news release,

Researchers have genetically engineered trees that will be easier to break down to produce paper and biofuel, a breakthrough that will mean using fewer chemicals, less energy and creating fewer environmental pollutants.

“One of the largest impediments for the pulp and paper industry as well as the emerging biofuel industry is a polymer found in wood known as lignin,” says Shawn Mansfield, a professor of Wood Science at the University of British Columbia.

Lignin makes up a substantial portion of the cell wall of most plants and is a processing impediment for pulp, paper and biofuel. Currently the lignin must be removed, a process that requires significant chemicals and energy and causes undesirable waste.

Researchers used genetic engineering to modify the lignin to make it easier to break down without adversely affecting the tree’s strength.

“We’re designing trees to be processed with less energy and fewer chemicals, and ultimately recovering more wood carbohydrate than is currently possible,” says Mansfield.

Researchers had previously tried to tackle this problem by reducing the quantity of lignin in trees by suppressing genes, which often resulted in trees that are stunted in growth or were susceptible to wind, snow, pests and pathogens.

“It is truly a unique achievement to design trees for deconstruction while maintaining their growth potential and strength.”

The study, a collaboration between researchers at the University of British Columbia, the University of Wisconsin-Madison, Michigan State University, is a collaboration funded by Great Lakes Bioenergy Research Center, was published today in Science.

Here’s more about lignin and how a decrease would free up more material for biofuels in a more environmentally sustainable fashion, from the news release,

The structure of lignin naturally contains ether bonds that are difficult to degrade. Researchers used genetic engineering to introduce ester bonds into the lignin backbone that are easier to break down chemically.

The new technique means that the lignin may be recovered more effectively and used in other applications, such as adhesives, insolation, carbon fibres and paint additives.

Genetic modification

The genetic modification strategy employed in this study could also be used on other plants like grasses to be used as a new kind of fuel to replace petroleum.

Genetic modification can be a contentious issue, but there are ways to ensure that the genes do not spread to the forest. These techniques include growing crops away from native stands so cross-pollination isn’t possible; introducing genes to make both the male and female trees or plants sterile; and harvesting trees before they reach reproductive maturity.

In the future, genetically modified trees could be planted like an agricultural crop, not in our native forests. Poplar is a potential energy crop for the biofuel industry because the tree grows quickly and on marginal farmland. [emphasis mine] Lignin makes up 20 to 25 per cent of the tree.

“We’re a petroleum reliant society,” says Mansfield. “We rely on the same resource for everything from smartphones to gasoline. We need to diversify and take the pressure off of fossil fuels. Trees and plants have enormous potential to contribute carbon to our society.”

As noted earlier, the researchers in Florida mention poplars in their paper (Note: Links have been removed),

Gymnosperms such as loblolly pine (Pinus taeda L.) contain lignin that is composed almost exclusively of G-residues, whereas lignin from angiosperm dicots, including poplar (Populus spp.) contains a mixture of G- and S-residues. [emphasis mine] Due to the radical-mediated addition of monolignols to the growing lignin polymer, lignin contains a variety of interunit bonds, including aryl–aryl, aryl–alkyl, and alkyl–alkyl bonds.(3) This feature, combined with the association between lignin and cell-wall polysaccharides, which involves both physical and chemical interactions, make the isolation of lignin from plant cell walls challenging. Various isolation methods exist, each relying on breaking certain types of chemical bonds within the lignin, and derivatizations to solubilize the resulting fragments.(5) Several of these methods are used on a large scale in pulp and paper mills and biorefineries, where lignin needs to be removed from woody biomass and crop residues(6) in order to use the cellulose for the production of paper, biofuels, and biobased polymers. The lignin is present in the waste stream and has limited intrinsic economic value.(7)

Since hydroxyl and carboxyl groups in lignin facilitate functionalization, its compatibility with natural and synthetic polymers for different commercial applications have been extensively studied.(8-12) One of the promising directions toward the cost reduction associated with biofuel production is the use of lignin for low-cost carbon fibers.(13) Other recent studies reported development and characterization of lignin nanocomposites for multiple value-added applications. For example, cellulose nanocrystals/lignin nanocomposites were developed for improved optical, antireflective properties(14, 15) and thermal stability of the nanocomposites.(16) [emphasis mine] Model ultrathin bicomponent films prepared from cellulose and lignin derivatives were used to monitor enzyme binding and cellulolytic reactions for sensing platform applications.(17) Enzymes/“synthetic lignin” (dehydrogenation polymer (DHP)) interactions were also investigated to understand how lignin impairs enzymatic hydrolysis during the biomass conversion processes.(18)

The synthesis of lignin nanotubes and nanowires was based on cross-linking a lignin base layer to an alumina membrane, followed by peroxidase-mediated addition of DHP and subsequent dissolution of the membrane in phosphoric acid.(1) Depending upon monomers used for the deposition of DHP, solid nanowires, or hollow nanotubes could be manufactured and easily functionalized due to the presence of many reactive groups. Due to their autofluorescence, lignin nanotubes permit label-free detection under UV radiation.(1) These features make lignin nanotubes suitable candidates for numerous biomedical applications, such as the delivery of therapeutic agents and DNA to specific cells.

The synthesis of LNTs in a sacrificial template membrane is not limited to a single source of lignin or a single lignin isolation procedure. Dimensions of the LNTs and their cytotoxicity to HeLa cells appear to be determined primarily by the lignin isolation procedure, whereas the transfection efficiency is also influenced by the source of the lignin (plant species and genotype). This means that LNTs can be tailored to the application for which they are intended. [emphasis mine] The ability to design LNTs for specific purposes will benefit from a more thorough understanding of the relationship between the structure and the MW of the lignin used to prepare the LNTs, the nanomechanical properties, and the surface characteristics.

We have shown that DNA is physically associated with the LNTs and that the LNTs enter the cytosol, and in some case the nucleus. The LNTs made from NaOH-extracted lignin are of special interest, as they were the shortest in length, substantially reduced HeLa cell viability at levels above approximately 50 mg/mL, and, in the case of pine and poplar, were the most effective in the transfection [penetrating the cell with a bacterial plasmid to leave genetic material in this case] experiments. [emphasis mine]

As I see the issues presented with these two research efforts, there are environmental and energy issues with extracting the lignin while there seem to be some very promising medical applications possible with lignin ‘waste’. These two research efforts aren’t necessarily antithetical but they do raise some very interesting issues as to how we approach our use of resources and future policies.

ETA May 16, 2014: The beat goes on with the Georgia (US) Institute of Technology issues a roadmap for making money from lignin. From a Georgia Tech May 15, 2014 news release on EurekAlert,

When making cellulosic ethanol from plants, one problem is what to do with a woody agricultural waste product called lignin. The old adage in the pulp industry has been that one can make anything from lignin except money.

A new review article in the journal Science points the way toward a future where lignin is transformed from a waste product into valuable materials such as low-cost carbon fiber for cars or bio-based plastics. Using lignin in this way would create new markets for the forest products industry and make ethanol-to-fuel conversion more cost-effective.

“We’ve developed a roadmap for integrating genetic engineering with analytical chemistry tools to tailor the structure of lignin and its isolation so it can be used for materials, chemicals and fuels,” said Arthur Ragauskas, a professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology. Ragauskas is also part of the Institute for Paper Science and Technology at Georgia Tech.

The roadmap was published May 15 [2014] in the journal Science. …

Fundamental mechanical behaviour of cellulose nanocrystals (aka nanocrystalline cellulose)

Emil Venere at Purdue University offers an excellent explanation of why there’s so much international interest in cellulose nanocrystals (CNC aka, nanocrystalline cellulose [NCC]) in his Dec. 16, 2013 Purdue University (Indiana, US) news release (also on EurekAlert), Note: A link has been removed,

The same tiny cellulose crystals that give trees and plants their high strength, light weight and resilience, have now been shown to have the stiffness of steel.

The nanocrystals might be used to create a new class of biomaterials with wide-ranging applications, such as strengthening construction materials and automotive components.

Calculations using precise models based on the atomic structure of cellulose show the crystals have a stiffness of 206 gigapascals, which is comparable to steel, said Pablo D. Zavattieri, a Purdue University assistant professor of civil engineering.

Here’s an image of the cellulose crystals being examined,

The nanocrystals might be used to create a new class of biomaterials that would have a wide range of applications. (Purdue Life Sciences Microscopy Center)

You’ll notice this image is not enhanced and made pretty as compared to the images in my Dec. 16, 2013 posting about Bristol University’s Art of Science competition. It takes a lot of work to turn the types of images scientists use into ‘art’.

Getting back to the CNC, this news release was probably written by someone who’s not familiar with the other work being done in the field (university press officers typically write about a wide range of topics and cannot hope to have in depth knowledge on each topic) and so it’s being presented as if it is brand new information. In fact, there has been several years work done in five other national jurisdictions that I know of (Sweden, Finland, Canada, Brazil, and Israel) and there are likely more. That’s not including other US states pursuing research in this area, notably Wisconsin.

What I (taking into account  my limitations) find particularly exciting in this work is the detail they’ve been able to determine and the reference to quantum mechanics. Here’s more from the news release (Note: Links have been removed),

“It is very difficult to measure the properties of these crystals experimentally because they are really tiny,” Zavattieri said. “For the first time, we predicted their properties using quantum mechanics.”

The nanocrystals are about 3 nanometers wide by 500 nanometers long – or about 1/1,000th the width of a grain of sand – making them too small to study with light microscopes and difficult to measure with laboratory instruments.

The findings represent a milestone in understanding the fundamental mechanical behavior of the cellulose nanocrystals.

“It is also the first step towards a multiscale modeling approach to understand and predict the behavior of individual crystals, the interaction between them, and their interaction with other materials,” Zavattieri said. “This is important for the design of novel cellulose-based materials as other research groups are considering them for a huge variety of applications, ranging from electronics and medical devices to structural components for the automotive, civil and aerospace industries.”

From an applications perspective (which is what excites so much international interest),

The cellulose nanocrystals represent a potential green alternative to carbon nanotubes for reinforcing materials such as polymers and concrete. Applications for biomaterials made from the cellulose nanocrystals might include biodegradable plastic bags, textiles and wound dressings; flexible batteries made from electrically conductive paper; new drug-delivery technologies; transparent flexible displays for electronic devices; special filters for water purification; new types of sensors; and computer memory.

Cellulose could come from a variety of biological sources including trees, plants, algae, ocean-dwelling organisms called tunicates, and bacteria that create a protective web of cellulose.

“With this in mind, cellulose nanomaterials are inherently renewable, sustainable, biodegradable and carbon-neutral like the sources from which they were extracted,” Moon said. “They have the potential to be processed at industrial-scale quantities and at low cost compared to other materials.”

Biomaterials manufacturing could be a natural extension of the paper and biofuels industries, using technology that is already well-established for cellulose-based materials.

“Some of the byproducts of the paper industry now go to making biofuels, so we could just add another process to use the leftover cellulose to make a composite material,” Moon said. “The cellulose crystals are more difficult to break down into sugars to make liquid fuel. So let’s make a product out of it, building on the existing infrastructure of the pulp and paper industry.”

Their surface can be chemically modified to achieve different surface properties.

“For example, you might want to modify the surface so that it binds strongly with a reinforcing polymer to make a new type of tough composite material, or you might want to change the chemical characteristics so that it behaves differently with its environment,” Moon said.

Zavattieri plans to extend his research to study the properties of alpha-chitin, a material from the shells of organisms including lobsters, crabs, mollusks and insects. Alpha-chitin appears to have similar mechanical properties as cellulose.

“This material is also abundant, renewable and waste of the food industry,” he said.

Development of US plant to produce cellulosic nanomaterials announced again or is this a new one?

There’s a new announcement from the Secretary of the US Department of Agriculture (USDA) about building a commercial production plant in Wisconsin for producing cellulosic nanomaterials that greatly resembles an earlier announcement in 2012. Let’s start with the new announcement, from the Dec. 11, 2013 USDA press release (h/t AgriPulse Dec. 11, 2013 news item),

U.S. Department of Agriculture (USDA) Secretary Tom Vilsack today announced a public-private partnership to rapidly advance the development of the first U.S. commercial facility producing cellulosic nanomaterial, a wood fiber broken down to the nanoscale. The partnership is between the U.S. Endowment for Forestry and Communities (Endowment) and the U.S. Forest Service.

“We believe in the potential of wood- based nanotechnology to strengthen rural America by creating sustainable jobs and adding timber value while also creating conservation opportunities in working forests,” said Vilsack. “This public- private partnership will develop high-tech outputs from the forest products sector, and promote the invention of renewable products that have substantial environmental benefits.”

The three-year partnership will promote cellulosic nanomaterial as a commercially viable enterprise by building on work done by the Forest Products Laboratory in Madison, Wis. The partnership seeks to overcome technical barriers to large- scale wood-based nanotechnology processing, while filling gaps in the science and technology that are needed for commercialization. Initial funding comes from the Endowment and the Forest Service. The partnership is currently seeking additional public and private sector funding.

Together with partners, this new venture will:

  • Emphasize the potential of wood- based nanotechnology for the economy and the environment.
  • Overcome technical barriers to commercialization of wood- based nanotechnology.
  • Demonstrate commitment to creating high paying jobs in rural America through value- added manufacturing and high value products.
  • Showcase the commitment of USDA and the Forest Service to innovation.

The previous announcement which I covered in my July 27, 2012 posting has some similarities, although they were announcing the expected construction of a pilot plant for a specific forest-derived cellulosic nanomaterial,,

According to the July 25, 2012 article by Rick Barrett originally published by Milwaukee Journal Sentinel McClatchy-Tribune Information Services) on the equities.com website,

The U.S. Forest Products Laboratory, in Madison, says it’s opening a $1.7 million pilot plant that will support an emerging market for wood products derived from nanotechnology.

…The pilot plant will supply nanocrystals to companies and universities that want to make materials from them or conduct their own experiments. For now, at least, it will employ just one person.

But while the Forest Products Laboratory wants to foster the technology, it doesn’t want to compete with businesses interested in producing the materials.

“We are part of the federal government, so we cannot compete against commercial companies. So if someone comes in and starts making these materials on a commercial level, we will have to get out of it,” Rudie said. That’s why, he added, the program has bought only equipment it can use for other purposes.

At a guess I’d say plans were changed (to my knowledge there’ve been no announcements about the opening of a pilot plant) and they decided that a commercial plant in a private/public partnership would be the way to go. I notice they’re very careful to use the term cellulosic nanomaterials, which suggests they will be producing not just the crystals mentioned in the 2012 story but fibrils and more.

On the Canadian side of things,, Alberta gave its pilot cellulose nanocrystal (CNC, aka, nanocrystalline cellulose [NCC]) plant a soft launch in Sept. 2013, as per my Nov. 19, 2013 posting,  and Quebec’s CelluForce plant (a  Domtar/FPInnovations partnership [private/public]) has a stockpile of the crystals and is, to my knowledge (my Oct. 3, 2013 posting), is not producing any additional material.

 

Future biomedical applications for CNC (cellulose nanocrystals, aka NCC [nanocrystalline cellulose]) from Polytechnic Institute of New York University (NYU-Poly)

It’s good to see a project that might result in applications for CNC (aka, NCC). I commented briefly about the CNC situation earlier today in my Nov. 25, 2013 posting about Lomiko Metals (based in Surrey, BC, Canada) and its focus on developing markets for its product (graphite flakes/graphene). By contrast, Canada’s CelluForce plant (in Québec) has stopped production to avoid adding to its stockpile (as per my Oct. 3, 2013 posting), Alberta has launched a pilot CNC plant (my Nov. 19, 2013 posting), Blue Goose Biorefineries in Saskatchewan was ramping up production according to my May 7, 2013 posting and someone, in a blog posting comment, claimed that Pure Liganin in BC produces CNC (which I cannot confirm since the company mentions neither CNC nor NCC).,

Back to happier matters, a research team from Polytechnic Institute of New York University (NYU-Poly) has discovered information that could be helpful for scientists working with protein polymers (from the Nov. 22, 2013 news item on Azonano,,

A team of researchers has uncovered critical information that could help scientists understand how protein polymers interact with other self-assembling biopolymers. The research helps explain naturally occurring nano-material within cells and could one day lead to engineered bio-composites for drug delivery, artificial tissue, bio-sensing, or cancer diagnosis.

The Nov. 21, 2013 NYU-Poly press release, which originated the news item, goes on to explain the CNC connection to this work,

Bionanocomposites provide a singular area of research that incorporates biology, chemistry, materials science, engineering, and nanotechnology. Medical researchers believe they hold particular promise because—unlike the materials that build today’s medical implants, for example—they are biodegradable and biocompatible, not subject to rejection by the body’s immune defenses. As biocomposites rarely exist isolated from other substances in nature, scientists do not yet understand how they interact with other materials such as lipids, nucleic acids, or other organic materials and on a molecular level. This study, which explored the ways in which protein polymers interact with another biopolymer, cellulose, provides the key to better understanding how biocomposite materials would interact with the human body for medical applications.

The materials analyzed were composed of bioengineered protein polymers and cellulose nanocrystals and hold promise for medical applications including non-toxic, targeted drug delivery systems. [emphasis mine] Such bionanocomposites could also be used as scaffolding for tissue growth, synthetic biomaterials, or an environmentally friendly replacement for petroleum-derived polymers currently in use.

I wonder if the researchers obtained their CNC from the production plant in Wisconsin (US), assuming it has opened since my July 27, 2012 posting featuring an announcement of future plans. Getting back to this latest work, here’s a link to and a citation for the paper,

Offhand I can think of only one Canadian laboratory (although I’m certain there are others), which is working on applications for CNC and that’s Mark MacLaclan’s lab at the University of British Columbia (UBC). For example, there is this ‘in press’ paper,

Lomiko Metals and Graphene Laboratories announce 3D printing spinoff company

A Nov. 25, 2013 news item on Azonano announces a new 3D printing company, Graphene 3D Labs,

LOMIKO METALS INC. (the “Company”) announced today the formation of Graphene 3D Labs Inc. to focus on the development of high-performance graphene-enhanced materials for 3D Printing. Dr. Daniel Stolyarov of Graphene Laboratories Inc. (“Graphene Labs”) was appointed CEO and Dr. Michael Gouzman, a leading expert in 3D Printing, was appointed VP of Engineering and Technology.

On February 12, 2013 the Company had entered into a Strategic Alliance Agreement (“SAA”) with Graphene Labs. The creation of Graphene 3D Labs, a spin-out of Graphene Labs, is a result of R&D efforts during the duration of the SAA.

It’s been a busy year for Lomiko Metals (based in Surrey, BC, Canada) as per my April 17, 2013 posting about its graphite flake testing and its graphite mine (Quatre Milles) in Québec and my May 30, 2013 posting about its agreement/strategic alliance with the Research Foundation of Stony Brook University (RF) based in New York State. This latest effort according to the Nov. 22, 2013 Lomiko Metals news release, which originated the news item, describes the reasons for creating a spinout company to pursue applications,

3D Printing is a new and promising manufacturing technology that has garnered much interest, growing from uses in prototyping to everyday products. Today, it is a billion dollar industry growing at a brisk pace. New developments in 3D printing will allow products with different components such as printed electronic circuits, sensors or batteries to be manufactured.

High quality graphite is a base material for producing graphene. Lomiko will provide graphite to Graphene 3D Labs as the exclusive supplier to Graphene 3D Labs and invest $ 50,000 in the start-up for 250,000 preferred shares which are entitled to dividends. Lomiko will require a minimum of $ 300,000 financing by May 1, 2014 to participate in the venture and further financings to participate in a series of graphene-related ventures in addition to work on a graphite resource at the Quatre Milles Project. The transaction is arm’s length and subject to the approval of the TSX. [Toronto Stock Exchange]

“Our involvement in Graphene 3D Labs is a concrete first step into the world of Graphene, 3D Printing and Printed Electronics. This is a rapidly developing new market for high quality naturalgraphite.” stated A. Paul Gill, CEO from the Graphene Live! Conference in Santa Clara, California held November 19-22, 2013.

Dr. Elena Polyakova, CEO of Graphene Labs, was a speaker on Graphene Live! and stated, “We anticipate graphene-enabled materials to revolutionize 3D printing. We anticipate strong demand in airspace, automotive, semi-conductor and advanced manufacturing industries.”

Currently Lomiko and Graphene Labs are working toward the integration of graphene-based products into end-user goods as set out in the Strategic Alliance. [emphasis mine] Lomiko’s high quality graphite and the extensive customer database cultivated by the experts at Graphene Labs will prove indispensable to reaching production and commercialization goals.

This business of developing a market for your raw materials is an approach the folks at CelluForce in Quebec and the new CNC (cellulow nanocrytals, aka, nanocystalline cellulose [NCC]) plant in Alberta might consider taking, if they haven’t already. (Note: My Nov. 19, 2013 posting both announces the new CNC in Alberta and makes mention of the CNC stockpile in  Québec.)

You can find out more about Graphene Laboratories here and about Graphene 3D Laboratories here. For anyone interested in the Graphene Live! conference, (Nov. 20-21, 2013), there will be presentations and audio available soon (as of Nov. 25, 2013) according to the website.

Alberta gave its cellulose nanocrystal (or nanocrystalline cellolose) production plant a soft launch in September 2013

It’s been a little over two years since Alberta’s proposed cellulose nanocrystal (CNC), then called nanocrystalline cellulose (NCC), pilot plant was first announced (my July 5, 2011 posting). I gather that the plant was quietly opened in Sept. 2013. Finding a news release about the event has proved to be a challenge. The Alberta Innovates website does not list it in its Newsroom while the Alberta Innovates Technology Futures website does list a news release (September 12, 2013Alberta’s one-of-a-kind CNC pilot plant commissioned: Cellulose-based ‘wonder material’ now available to researchers, industry partnersf), despite numerous efforts on my part (try it yourself), I’m unable to access it. Happily, I was able to track down some information elsewhere.

First (in the order in which I found the information), there’s an Oct. 2, 2013 news item on the WorkingForest.com website submitted by Pulp and Paper Canada),

Alberta’s cellulose nanocrystals (CNC) pilot plant, which produces up to 100 kilograms of CNC per week, was commissioned in early September at Alberta Innovates-Technology Futures’ (AITF) Mill Woods facility before a crowd of researchers, industry leaders and government representatives.

The $5.5-million pilot plant, created through a collaboration of the governments of Canada and Alberta in partnership with industry under the Western Economic Partnership Agreement (WEPA), uses wood and straw pulp from plants such as flax and hemp to create CNC for testing in commercial applications that will lead to production.

“Alberta Innovates-Technology Futures is proud to host and operate Western Canada’s only CNC pilot plant,” said Stephen Lougheed, AITF’s president and CEO. “We’re able to provide researchers with more CNC than ever before, thereby accelerating the development of commercial applications.”

The grand opening of the CNC pilot plant’s is planned for 2014.

Then, there was more information about the plant and the event in Catherine Griwkowsky’s Sept. 12, 2013 article for the Edmonton Sun,

A new cellulose nanocrystals (CNCs) pilot plant will take wood and agricultural fires and turn it into a form that can make products stronger, give them sunlight-absorbing properties, add a negative electromagnetic charge and more.

The $5.5-million project in Mill Woods will churn out up to 100 kilograms of the crystals each week.

Technical Lead Frank Tosto said researchers will study various properties of the crystals, and work with an internal team as well as external industry and other researchers to transform knowledge of the properties into ideas for applications. Later, the team may experiment with unconventional sources of cellulose.

The CNCs can be used for drilling fluids, paints, industrial coatings, automotive components, building materials, plastics and packaging.

The process [of refining hemp, etc.] breaks down cellulose into smaller building blocks using a chemical process of acid hydrolysis, that separates crystal formations in cellulose from other structures. The width is between five to 10 nanometres with a length of 150 to 200 nanometers. To scale, cellulose fibre would be the size of a hockey rink and the nano crystal would be like a pen or pencil, he explained.

Ultimately, Tosto hopes they will find commercial applications for the CNCs. The pilot should last five to seven years. He said it’s hard to think outside the box when they don’t know where all the boxes are.

I’d love to know if any of the entrepreneurs who contacted me privately about accessing CNC so they could develop new applications are now able to purchase product from the Alberta plant or from the one in Quebec (CelluForce), which had a stockpile last I heard (my Oct. 3, 2013 posting). It seems odd to be building another plant when the country’s first such plant has stopped production. Meanwhile, there’s some action on the international scene. An Israeli startup company, Melodea has developed its own CNC/NCC extraction process and has received money to develop applications, from my Oct. 31, 2013 posting),

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).

You’ll note Melodea’s process extracts CNC from the paper industry’s sludge which leads me to this question: will there be any discussion of this extracting CNC from sludge technique at the 2014 TAPPI (Technical Association for the Pulp, Paper, Packaging and Converting Industries) nanotechnology conference being held in Vancouver (Canada), June 23-26, 2014 (mentioned in my Nov. 14, 2013 posting about the conference’s submission deadline, Nov. 22, 2013)?

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’.
