Bio4Energy 2023: Full Steam Ahead in Education, Research, Forming Collaborations

/in /by

With the effects of the pandemic largely behind in northern Europe and Scandinavia, 2023 was a year of full steam ahead for the research environment Bio4Energy. This applied to the production of scientific research results, as well as education and training. It was also a year in which new collaborations and partnerships were formed.

This is the message of the 2023 Bio4Energy Annual Report, issued this month. It also says that the seven research platforms, which deliver scientific methods and tools for developing advanced biofuels, “green” chemicals and bio-based materials; had more collaboration amongst themselves than before.

Nine so-called Strategic Projects were granted on this basis of cross platform and cross-organisation cooperation. Four of them have just been listed on the Bio4Energy website.

With the effects of the pandemic largely behind in Bio4Energy’s northern European region, 2023 was a year of full steam ahead for the research environment. This applied to the production of scientific research results, as well as education and training.

Both scientific researchers and communications actively developed external collaborations. Once again, Bio4Energy helped promote the annual Advanced Biofuels Conference, which had a focus on renewable transport fuel for the maritime and airline industries.

As part of the core curriculum of the Bio4Energy Graduate School on the Innovative Use of Biomass, the team behind it launched a new course on the history of biorefining in Nordic countries, which received good reviews by students and professors in its first round.

It has a focus on the Nordic countries; Sweden, Finland and Norway. This is not only because the Bio4Energy research environment is based here, but also because of their historic importance as a hub for forestry adapted to the geological and climatic conditions of the boreal belt. Examples from Canada are an important part, because of the development of its biorefinery sector that has unfolded in parallel and partly on the same latitudes.

News in the form of popular sciences attracted attention, notably in the areas of industry – academy collaboration to lay the foundation for “green” steel making, which is expected to contribute to reducing greenhouse gas emissions from iron and steel making industries.

So did news articles on the commercialisation of bio-based hydrogels, which are slated for use in wound healing and advances in improving bio-based input materials for biorefinery production, notably wood or woody residues from trees.

A comprehensive round-up of the chemistry involved in biorefinery processes had many views, as did news on Bio4Energy’s new representative in Bio-based Industries Consortium (BIC), which latter props up the industrial Circular Bio-based Joint Undertaking (CBE JU). It is a partnership between BIC and the European Union.

September Start for Bio4Energy’s Training to Scale up Bio-based Innovations

/in /by

Bio4Energy’s training on the scale up of bio-based innovations is starting again in September. The application is open as of today.

The backdrop is substantial new investments in test beds and development facilities in the region of northern Sweden where the research environment is based.

“We will go onsite visiting not only pilot [installations] of different types, but whole factories in our network of actors based along the coast at Örnsköldsvik, Piteå and Umeå.

“We will see this great variation and speak to the developers themselves”, said course coordinator Francesco Gentili.

“We will go onsite visiting not only pilot installations of different types, but whole factories in our network of actors based along the coast at Örnsköldsvik, Piteå and Umeå. We will see this great variation and speak to the developers themselves”.

He is not only an associate professor at the Swedish University of Agricultural Sciences, but also the man behind facilities for microalgae research and development run in collaboration with regional energy utility Umeå Energi.

Biorefinery Pilot Research, as the course is called, is the flagship of the Bio4Energy Graduate School on the Innovative Use of Biomass.

Bio4Energy draws together the regions foremost universities and institutes dealing with the development of methods and tools for conducting biorefinery based on woody residues and industrial organic waste. As such, it is on a mission to provide education and training to help provide the sector with knowledge workers of tomorrow’s bioeconomy and advanced students with top-of-the-line education.

The course is offered as a mixture of intensive days of onsite visits—starting 2-4 September at Piteå—with time in between where students work to develop their own projects. They do this either by implementing an aspect of upscaling in their own PhD project or; if they are postdoctoral fellows established as researchers; they may create something new.

“We speak to and learn from capable fundamental researchers, all the way up to industrialists”.

“We speak to [and learn from] capable fundamental researchers, all the way up to industrialists”, Gentili told Bio4Energy Communications.

The group goes on study visits to well-known companies in the sector such as SunPine and the large pilot LTU Green Fuels at Piteå, as well as their institute partner in Bio4Energy, RISE Energy Technology Center.

Further south, at Örnsköldsvik, key contacts in the Bio4Energy Industrial Network will show them the new RISE Bioeconomy Arena, Domsjö Fabriker, SEKAB and RISE Processum. At Umeå, finally, Gentili will showcase the algae pilot and include a tour of Arevo, which has gone from being a Bio4Energy researcher upstart to a full-grown company offering a new kind of plant nutrition product that does not create toxic leakage, while being highly efficient.

“We stay, eat and study together and it creates the opportunity for networking”, Gentili said, adding a reflection on the bigger picture;

“It creates job opportunities. We train people to know the infrastructure and strengthen the collaboration in our region”.

Bio4Energy Partner LTU Part of ‘Largest Investment in Material Science in Sweden’

/in /by

A Swedish funder of research in the bio-based sector has announced the largest investment ever in the northern European country in terms of sustainable material science, and notably in infrastructure to advance it.

Bio4Energy partner Luleå University of Technology (LTU) is one of seven research universities to benefit, having won a hefty SEK52 million (€4.6 million) grant to fund instrumentation that will allow researchers quickly to measure various material reactions to flow, pressure or load and to variations in climate.

“The equipment will be unique in Sweden. We are right here in northern Sweden where the large industrial investments towards the green transition are located”, said Fredrik Forsberg, Bio4Energy expert at fluid and experimental mechanics at LTU.

“We are going to build a strong node for material science research; focusing on minerals, metals and hydrogen; all of which are essential raw materials in this transition”, Forsberg added.

“We are going to build a strong node for material science research; focusing on minerals, metals and hydrogen; all of which are essential raw materials in this transition”.

The vision of the Wallenberg Initiative Materials Science for Sustainability (WISE), where the seven universities are members, is to “enable sustainable technologies with positive impact on our society by understanding, creating and controlling complex materials”, according to its homepage.

It is the single largest investment in material research in Sweden—the share going to LTU is one tenth of the total—and the Knut and Alice Wallenberg Foundation is behind it.

In the case of LTU, the grant monies will be invested both in infrastructure at the university and at the southern Sweden-based synchrotron Max IV Laboratory; where beamlines for very advanced X-ray-based research is available for scientists from all over the world.

“We expect to start using the new equipment a year from now. It will be available to all WISE researchers and for all in joint projects regarding sustainability issues”, Forsberg said.

From the presentation late 2019 of its Green Deal, the European Union started referring to the “green transition” as being a bridge in time to meeting goals in terms of cutting greenhouse gas emissions and arresting environmental degradation.

Advanced Characterisation Techniques at the Luleå Material Imaging and Analysis Facility (WISE ACT @LUMIA) at Luleå University of Technology include high-resolution 3D X-ray imaging (dynamic/high-energy/spectral XCT) and precision milling (laser ablation FIB) coupled with scanning electron microscopy (SEM). The platform offers excellent capabilities for analysis related to the new technologies emerging in northern Sweden, the hotspot for the green transition. Key research areas, in close collaboration with leading industry, include fossil-free steel, carbon dioxide and hydrogen storage, sustainable batteries, extraction of critical raw materials, and additive manufacturing.

‘Getting Prepared to Have Right Material Base’: Chemistry in Biorefinery in New Report

/in /by

As economies are moving closer to a substantial fossil fuel phase-out, the need increases for a total overview of what the bio-based sector can bring to the table to replace it.

Bio4Energy researcher Carlos Martín Medina, Biopolymers and Biochemical Conversion, has spearheaded one such initiative giving an overview of how far we have come in terms of knowing the chemistry of the processes in factories where biofuels, “green” chemicals or bio-based materials are made: Biorefineries.

Together with colleagues from Spain and Italy, he has drawn together the latest advice from a range of international scientists on the Chemistry in Biorefineries and what substantial issues remain, in a new report.

“We are all concerned about [the consequences of using] fossil fuels. We need a clear idea of the post-petroleum era. We are getting prepared to have the right material base”, Martín told Bio4Energy Communications in an interview.

“What we are contributing with here is a representative overview of recent updates of known issues in biorefineries. These are novel contributions by first line scientists”, Martín said.

The Cuban native is one of Bio4Energy’s truly international PIs, bridging a position between Umeå University, Sweden and the Inland Norway University of Applied Sciences, Norway.

“What we are contributing with here is a representative overview of recent updates of known issues in biorefineries. These are novel contributions by first line scientists”.

As always when it comes to making commodities—even such that people will want to consume in the future—ventures have to be economically viable, as well as socially and environmentally sustainable.

“It is important to know the chemistry of [every] single process to be able to optimise and achieve higher yields and purity, and to avoid side reactions. In a biorefinery the first goal is to separate the three main components of biomass in the best way possible, so that each can be directed to different end products”, Martín explained.

Such products could be ethanol made from cellulose or resins made from lignin, he said. Although different input biomass materials are in focus in different parts of the world, the lesson contained in the themed collection of articles just out, in many cases are the same.

Is there enough biomass?

Martin’s answer to the question as to whether there is enough biomass for biorefinery production to make a substantial contribution in the post-petroleum era is a resounding “Yes.

“There are many different sources of residual plant biomass: Crop residues, forest residues, wood processing residues.

“Wood should mainly go into building materials and furniture manufacturing. We don’t want to clear out forests, [but instead] take advantage of materials that are not exploited today”.

The research environment Bio4Energy makes methods and tools for conducting biorefinery—a refinery based on biomass residues from various sectors to produce renewable fuel, materials and chemicals.

2022 Bio4Energy Annual Report Is Out

/in /by

The 2022 Bio4Energy Annual Report is out, breathing optimism and comeback after the years with the Coronavirus disease (COVID-19).

It tells the tale of launching a new website for the research environment and of rising numbers of PhD defenses passed. PhDs in this context are advanced students in Bio4Energy’s sector of biorefinery and bioenergy based on wood or organic waste. Their work is at the heart of Bio4Energy’s contribution to advancing science.

As is custom, each of Bio4Energy’s seven research platforms has its own page. Here its members’ progress is detailed over the year and the platform’s reason for being described. Two new platforms leaders stepped into their roles in 2022 and are pictured.

Important news developments are described in the media and outreach section, followed by awards and special commissions.

All 11 members of the Bio4Energy Advisory Board are pictured. They serve as a link to industry and give advice to the Bio4Energy Board and programme managers.

Breakthrough Innovation: Hydrogels from Norwegian Kelp to Be Commercialised

/in /by

Bio4Energy researchers are behind a breakthrough innovation that can be used to make bio-based and biodegradable hydrogels.

Hydrogels are key components in materials used to restore or maintain human health such as wound healing, tissue engineering, artificial organs or everyday contact lenses.

The ingenuity of hydrogels lies in a dichotomy: While they are able to absorb and hold water, they do not decompose as a result.

However, as much as hydrogels are an indispensable part of modern medicine, today only synthetic hydrogels of the kind desired are available on the market and they are resource-intensive to produce, according to an article at the website of Luleå University of Technology, where the Bio4Energy researchers work.

Applying nanotechnology to brown algae grown in Norwegian waters, scientists Kristiina Oksman and Linn Berglund were able to skip steps that are paramount to making hydrogels of the synthetic kind. This means that the new bio-based technology requires less energy at production and generates less waste.

Nano-scale processing of the starting material also means that good quality hydrogel can be ascertained, as the cellulose is separated into ultra-small fibres and desirable qualities of the alginate salts are retained.

Alginor ASA, a Norwegian firm, has bought the resulting patent and are constructing a processing plant for this type of brown kelp, Laminaria Hyperboream.

“Alginor ASA wants to use the method to make full use of the harvest of Laminaria Hyperborea, or brown kelp, a species that is common in Norwegian waters”, professor Oksman said.

Field Trials Confirm: Aspen Trees May be Modified for Easier Access for Biorefinery Production

/in /by

Field trials of transgenic aspen trees have confirmed that genetic modification is indeed a possible avenue for rendering wood less resistant to breakdown into components suitable for making biofuel, “green” chemicals or bio-based materials.

Research just out shows not only how to modify tree plants for superior yield of desired sugar-based content, but also offers industry or investors proof-of-concept results from pilot-scale trials performed for the most successful combinations or “constructs” in science speak.

Most innovations require Proof of Concept to survive past the early stages of product development. It is a formalised way of providing evidence that demonstrates that a design concept or business proposal is feasible.

For the last decade, Bio4Energy has shepherded field trials of hardwood species such as aspen, under the leadership of professor Ewa Mellerowicz, Swedish University of Agricultural Sciences.

Collaboration partners include programme manager Leif Jönsson’s research team at Umeå University, as well as Bio4Energy research leaders at RISE Research Institutes of Sweden, the Wallenberg Wood Science Centre and others.

The results are expected to bring considerable benefit to the scientific community, given that no less than 32 so-called lines of genetically modified aspen trees previously evaluated only in greenhouse trials, have been grown and studied for five years in field plantations in Sweden.

“Whereas there are many examples of genetically modified trees that are improved in the greenhouse experiments, the trees with improved properties in the field are exceptional”, Mellerowicz told Bio4Energy Communications.

The fact that the field trials used material pre-selected from extensive greenhouse experiments, testing very large numbers of constructs, let the scientists bring about optimal results in the field. This way, the trees grew faster (produced more wood) and were more ready to release sugar-rich polymers, which are desired input materials for making biorefinery products.

“By [implementing a] systematic long-term and multi-level testing strategy, we were able to identify certain unknown function genes that improve field productivity and saccharification yield”, according to Mellerowicz.

Moreover the best transgenic lines were processed in a pilot-scale reactor, mimicking industrial conditions, to provide proof of concept for the strategy.

“The identified genes will be of particular interest to modify, using non-transgenic approaches to produce feedstocks that are GMO free, but have improved performance in the field and in the biorefinery”, she said.

This means that more research is needed before the findings can be demonstrated as a new technology, but the advantage created is that genes have been identified that could be targets for it.
