Late October, leading researchers on the quality of biomass-based fuels met as an Impacts of Fuel Quality on Power Production conference—given this year at Snowbird, Utah, U.S.A.—with one in five talks being delivered by a scientist from Bio4Energy.

While the conference is one of the most respected recurrent events on biomass combustion and gasification research, this year was special a special one for Bio4Energy—and indeed for its offshoot research and development programme Bio4Gasification.

"This is not just any conference but The Conference in fuel quality and with a large international following. This year we have 15 presentations related to Bio4Energy, mostly from the [Bio4Energy] Thermochemical Platform. This happens to be 20 percent of all presentations", Umeå University professor Rainer Backman said just ahead of travelling to the conference from northern Sweden.

"What is so nice about this is the fact that all our presentations are based on scientific articles which will be published in well-respected journals next year", said Backman, who took over the leadership of the Bio4Energy Thermochemical Platform earlier this year.

So what puts Bio4Energy apart when it comes to having a handle on the quality of biomass-based fuels?

For starters, its researchers have long-standing expertise on wood as a raw material in biofuel production. A string of reports have shown that woody feedstock is among the most efficient in terms of energy use and environmental impact, if the conversion method used is entrained-flow gasification.

January 2015 will see the startup of a high-efficiency, 65 million-Swedish-kroner demonstration unit for the torrefaction of woody biomass at Holmsund, Sweden. This technology for roasting biomass invented by Bio4Energy researchers has already been tested at pilot facilities at Umeå, a 20-minute drive from the demonstration unit in progress. While not fully operational until April 2015, the demonstration unit would be "cold started" at the beginning of 2015, according Anders Nordin of Umeå University, and for the first two years turn woody sawdust into tightly packed, high-energy density and hydrophobic heating pellets.

Nordin is a co-owner of BioEndev which small firm built the demonstration unit together with Swedish industrial partners such as BRUKS and SCA. This week, he and the BioEndev chief technical officer Ingemar Olofsson for the first time gave regional industry representatives and academia a tour of the facilities, consisting of several industrial buildings tucked away behind a barbed-wire fence in a forested area just off the main road to Holmsund from Umeå.

Projects on Woody Biomass to Benefit Industry Within a Few Years Print E-mail

Photo by Anna Strom©.Making the stuff of bio-based plastics, identifying new value chains in "forest" biorefinery, finding the perfect method for quick drying sludge or pinning down the best kind of pine for making bio-based products. These are the topics of four research projects whose instigators, all Bio4Energy researchers based in northern Sweden, were awarded grants in the latest round of funding by the Swedish Research Council Formas.

"Swedish forestry industry needs to transition from traditional production of wood and pulp to a more varied and sustainable production of bio-based products", said Formas first secretary Gia Destouni in a press release announcing the grants, in lieu of justification for the need of the research projects thus enabled.

This is taken to mean that the industry could benefit from a move from pulp and paper making only, to full-scale biorefinery operations in which products as diverse as biofuels, "green" chemicals and specialty acids or the like could be made in one production unit.

Each of the four Bio4Energy research proposals, applied projects expected to result in methods or processes for industry to incorporate in their production within a few years, aim to add one small piece of the puzzle of such a transition:

  • Efficient conversion of forest biomass insoluble polyesters with potential use in lignocellulosic feedstock biorefineries;

  • Rapid drying of sludge from forestry industrial operations using vacuum technology;

  • Large-scale expansion of biorefinery: New value chains, products and the efficient use of woody biomass and;

  • Selection of elite populations of pine for the sustainable production of new bioenergy and carbohydrate products.

Ligin 2014: Bio4Energy Presenters Acknowledged Print E-mail

Bio4Energy would like to acknowledge its researchers who contributed a presentation to the Lignin 2014 conference, held 24-28 August at Umeå, Sweden.

Lignin-2014 Sandra-Winestrand Photo Anna-Strom 265x177Bio4Energy researcher Sandra Winestrand of Umeå University and the Billerud-Korsnäs group.'Smart' packaging designed to prolong the shelf-life of food

Sandra Winestrand and colleagues at Umeå and Karlstad Universities

Edited abstract: Extending the shelf-life of packaged food is a potential way of reducing food waste. One possible way to do this is by using a system that scavenges the oxygen inside a package equipped with an oxygen barrier. A common way to scavenge oxygen inside a package is to insert a small sachet containing iron powder. An alternative to this is to use oxygen-scavenging enzymes that can be incorporated directly in the coating layer of the package.

The phenol-oxidising enzyme laccase uses molecular oxygen as its oxidising substrate, and could therefore be used for the latter type of application. Laccase can use derivatives of lignin as its reducing substrate, which would be interesting from a biorefinery perspective since lignin derivatives are underused co-products in biorefinery based on lignocellulosic feedstock. The aims of the investigation were to understand how the properties of lignin derivatives affected the enzymatic reaction and the quality of the coating layer.

The study involved the use of lignin derivatives and preparations of size-fractionated lignin derivatives from industrial processing of lignocellulose. The molecular properties of the lignin derivatives before and after oxidation by laccase were investigated, as well as the capability of films and coatings to scavenge oxygen. The results indicate that laccase-catalysed cross-linking decreases oxygen levels and improves the water stability of the packaging material.

Lignin-2014 Art-Ragauskas Photo Anna-Strom 185x265Art Ragauskas of the University of Tennessee-Knoxville, U.S.A., develops polyurethane applications from lignin, together with industrial partners. Photo by Anna Strom.Usually burnt to heat the facilities at pulp and paper-making operations after valuable carbohydrate components such as cellulose have been separated from the woody feedstock—and sometimes cursed for its tendency to stick like glue to the other components of the wood—the polymer lignin, making up almost a third of the wood in trees, has become hot property in research and development (R&D) geared at making bio-based products.

So what’s new, you might wonder. Biorefinery operators such as Borregaard of Norway and Domsjö Fabriker of Sweden have been using lignin for other products than energy for some time, mainly as a component of cement. Carbon fibres have been developed for various applications, for instance by the Swedish research institute Innventia; and there is Borregaard occupying a niche with the way in which it makes vanilla flavouring from the lignin polymer. Still, as biomass researcher John Ralph of the U.S.-based University of Wisconsin-Madison said in a recent interview with Swedish science journalists, "Nothing has come to the top yet as being a winner application" made from lignin.

Part of the reason for that is likely the complexity of lignin—making it hard to break away from the rest of the wood and perhaps even to understand—and its tendency to cling to the carbohydrates cellulose and hemicellulose inside the wood, like a cement holding them together. After all, lignin is what gives plants their sturdiness and allow them to reach their stems towards the sky despite gravity's pulling the other way.

'Zip' ligninLignin-2014 John-Ralph Photo Anna-Strom 265x177University of Wisconsin-Madison professor John Ralph, who is also a researcher at the Great Lakes Bioenergy Center, is the man whose research group has invented a method designed more easily to zip lignin apart. Photo by Anna Strom.

Either way, Ralph should know. On 27 August he presented a Lignin 2014 conference with groundbreaking fundamental research on how to alter trees from within, by introducing a modification designed to make its lignin content more malleable (watch a video excerpt of his presentation on http://bio4energy.se). The result would be a tree, say a poplar tree, with additional readily cleavable bonds in a part of its lignin content (in the so-called lignin backbone). The new lignin present in a tree thus modified should be easier to cleave into smaller pieces and to break away from the rest of the wood. Lignin researchers refer to this method, or rather its result, as "zip" lignin.

The Lignin 2014 conference started Sunday 24 August with a 'Get Together' at Umeå, Sweden, at the Umeå University Arts' Campus. Monday 25 August saw several distinguished researchers present including Japanese Noritsugu Terashima of Nagoya University, Niko Geldner of the University of Lausanne in Switzerland and—last but not least—Norman Lewis of Washington State University in the U.S.A..

From Bio4Energy Henrik Serk spoke on 'Cooperative lignification of Arabidopsis xylem vessels', while Bo Zhang revealed that 'PERSIFONE2 regulates Histone H3K4 Methylation of caffeic and O-methyltransferase in Arabidopsis'. Both are affiliated with Umeå University. Moreover the head of the Bio4Energy Feedstock Platform, Björn Sundberg of the Stora Enso group, chaired a session on 'Lignin monomer biosynthesis and transcriptional regulation'.

Tuesday 26 August was a day for lignin analysis. Among a number of high-caliber speakers, analytical chemist Wout Boerjan of the University of Gent in Belgium explained how systems biology might be used to understand phenolic metabolism in trees. Others, such as Gerald Tuskan of the Oak Ridge National Laboratory, U.S.A., said that rich genomic resources facilitated progress in understanding the way in which wood is formed.

Wednesday 27 August saw the start of the industry part of Lignin 2014. A scientist in the absolute forefront of fundamental lignin research, John Ralph of the University of Wisconsin-Madison, U.S.A., told the conference about how to "design plant cell walls for deconstruction". Ralph is the man who invented the concept of "zip" lignin, a type of lignin that would be easier to separate from the rest of the wood in trees than lignin which has not been modified. In the afternoon, a cavalcade of distinguished folks on the side of applied lignin research, and on the side of product development, took the stage. University of Stellenbosch researcher Emile van Zyl (South Africa), Claus Felby of the University of Copenhagen (Denmark) and Guro Elise Fredheim of the Norwegian biorefinery group Borregaard were among them. Session chair was Bio4Energy researcher Torbjörn Lestander, professor at the Swedish University of Agricultural Sciences (SLU). Also from Bio4Energy and the SLU, Amir Mahboubi presented on 'Carbon-13 tracking of wood biosynthesis in hybrid aspen'.

Finally, Thursday 28 August Art Ragauskas of Georgia Tech in the U.S., probably the world's leading researcher on the applied side of lignin science, told the conference about 'Lignin: From cell wall to material'. From the Bio4Energy Industrial Network, Hans Grundberg of the Sweden-based Domsjö Fabriker biorefinery talked about "lignin business development" and "new opportunities". Just ahead of closing Lignin 2014, Peter Axegård of Innventia described the work of that Bio4Energy member research institute to develop cost-efficient carbon fibres from lignin. And Bio4Energy researcher Sandra Winestrand of the pulp and paper maker Billerud-Korsnäs talked on 'Lignin derivatives and laccase in oxygen-scavenging films and coatings'. Such films and coatings may be used, for instance, in bio-based food packaging.

Photo by Anna Strom, Bio4Energy.With just over two weeks to go to the start of the Lignin 2014 international conference, its organisers express satisfaction at the wide range of speakers and attendees having signed up to hear of the latest scientific progress and future applications of lignin, one of the most abundant polymers in plants and so the wood of trees. The discussions are set to cover both the biological and chemical side of lignin research—in fact, a chief objective is to bring the two sides together in one conference—and with an entire session devoted to industrial development of lignin applications. Beginning of August, 144 people had signed up to attend the conference, together with 21 presenters who represent the absolute top-runners in the science or industrial application of lignin.

"We are quite pleased with the abstracts [or scientific summaries of presentation topics] we have received. There is a good spread between biologists and chemists, and [representatives of] a few companies are coming”, according to Bio4Energy plant biologist This e-mail address is being protected from spambots. You need JavaScript enabled to view it who is an associate professor at Umeå University and the Umeå Plant Science Centre (UPSC).

Notably, confirmed speakers include John Ralph and Norman Lewis, both active at American universities; and Wout Boerjan in Belgium. All three are at the forefront of developing the basic science of lignin and notably its biosynthesis and analysis. On the side of industrial application, Martin Lersch of the multinational Borregaard biorefinery group, as well as Hans Grundberg from the Bio4Energy industrial partner Domsjö Fabriker biorefinery at Örnsköldsvik, will give talks. So will the man who summarised knowledge of the development of industrial lignin applications in a string of scientific review articles: Art Ragauskas.
