Biomass Feedstock, PhD Education, Synchrotron Research in Focus at Bio4Energy Event

The recent Bio4Energy Researchers’ Meeting, drawing together sixty of its researchers to meet at Umea in northern Sweden, is real-life example of the deliveries that Bio4Energy took on making as a Strategic Research Environment, appointed by the Swedish government.

Biomass input materials for making renewable fuels, chemicals and materials

The members of the Bio4Energy Forest-based Feedstocks platform are designing trees that are better suited to resist challenging climatic conditions and to grow faster. Tree genes are studied in depth for the purpose of knowing how to enable an easy separation of the polymers in the wood matrix, for the production of advanced biofuels, “green” chemicals and bio-based materials. Four group leaders presented their latest research on wood engineering and characterisation, as well as resilience in times of climate change.

Education and training for advanced students: Tomorrow’s knowledge workers of the bioeconomy

Bio4Enegy’s core curriculum is contained in the courses of its Graduate School. Biorefinery Pilot Research gives students access to the unique park of pilot and demonstration facilities that line the coast of northeastern Sweden. Students construct and conduct their own projects to experience the innovation process hands on. First-hand access to professionals in industry and their peers allow for networking.

The new History of Biorefining in Nordic Countries‘ training paints the background of biorefinery development, as well as current trends and progress. Study visits and sessions on sustainability challenges alert students to the fact that we need to do better tomorrow to achieve circularity; efficient and effective production systems with low or no pollution escaping out into the environment.

Course coordinator Francesco Gentili flagged that Biorefinery Pilot Research will be given in connection with the Nordic Wood Biorefinery Conference at Örnsköldsvik in autumn 2024, while Carmen Cristescu outlined the outcomes of the first ever edition of History of Biorefining, which just concluded in November this year.

Shining bright like a Bio4Energy student

Eleven of them painted the gist of their bio-based projects in minutes-long talks and fleshed them out later on research project posters, which were the focus of discussion during mingling time. Three winners of Best Poster Presentation were selected by a jury composed of more senior Bio4Energy colleagues.

Role of Forests in Reining in Climate Change, Producing Energy

When it comes to the role of the forest in a perspective of climate change mitigation and energy production, a full picture including all aspects impacting their use and benefits is required to start to making sense of the “undeniably complex” discussion taking place in the media and politics.

All aspects of the forest as an economic resource, a provider of recreational value and its capacity for carbon sequestration should be considered, according to an academic expert on the matter.

Professor in Economics Robert Lundmark, Luleå University of Technology, tries to do just that, in a new report from independent nonprofit organisation Centre for Business and Policy Studies (SNS), headquartered in Stockholm, Sweden but with a 30-country-strong membership, according to its website.

Centering on the case of Sweden, with its history of forestry and timber exports, Lundmark starts by discussing the economically profit-bearing aspects of forestry. Timber and renewable energy production both bring revenue to an important business sector and prop up the Swedish economy.

He goes onto billing production of bio-based (or “green”) chemicals as having a beneficial social impact; along with forests or forested areas set aside for recreation or tourism activities.

Biodiversity and its protection and the forest’s capacity to act as a carbon sink, are among environmental considerations, he holds.

All these aspects should be included in a total analysis, according to Lundmark; for any estimates of appropriate trade-offs between the different areas to make sense.

“This is existing knowledge put in a different perspective… It is a balancing act to arrive at an optimal utilisation of forests. We need to consider all societal values or we can easily go wrong”.

Role of science, politics, markets

He stresses, however, that the role of science is to provide assessments and that of politics to correct missteps due to market “failure”.

“A functioning market guarantees an efficient allocation of forest resources. That is how it works in the trading of goods and services. The role of politicians is to correct market failures, for instance in cases where forest owners are not paid for preserving all benefits of the forest. That is why we highlight the discussion about internalising the cost of goods and services”.

A quick check of the Oxford Languages gives that to internalise in an economic sense, means to incorporate costs as part of a pricing structure, especially social costs resulting from the manufacture and use of a product.

Forests as a carbon sink

The assessments that scientists do are still important, because any attempts at cutting greenhouse gases must be cost efficient, according to Lundmark.

“We see that compensation would be required for change to be made on a large scale. Today forest owners are not compensated for leaving the trees in the forest” to promote longer rotation periods.

He says that the starting point is to recognise that forests and their trees are a finite resource and one that becomes more and more in demand along with economic growth.

“It is undeniably a complex debate with many dimensions to account for: Forest management, ecology, social and economic aspects and technical aspects. All of them must come into consideration when we estimate benefits and trade-offs”, Lundmark said.

Expert Report

The Role of Forests in the Energy and Climate Transition, Summary in English

Bio4Energy is Delivering Methods, Tools to Industry as Promised

Regional collaboration and research in the areas of thermochemical conversion of biomass and feedstock pre-processing, respectively, were on the menu as Bio4Energy scientists and advanced students met at Skellefteå, Sweden this month.

The event showed, most notably, that a good decade after its start, the Bio4Energy research environment is indeed doing what it set out to in 2010: Delivering methods and tools in the areas of bio-based materials, “green” chemicals and advanced biofuels.

Thermochemical Conversion, one of two process platforms in Bio4Energy, is cooperating with leading actors in industry; to provide the foundations for replacing fossil fuels with biocarbon in steel-making operations.

Another branch of the platform is developing “green” carbon black from forest industrial residue; the early news of which spurred interest from European and Russian industry, eager to follow developments.

As we reported in March, the Feedstock Pre-processing platform not only keeps delivering dried or fractionated biomass to customers in industry, but also eyes a shift in focus to examine the ways in which critical raw materials can be supplied to the region in a safe and sustainable manner.

Finally, the meeting received a run down on current European Union policy developments affecting the forest industrial sector.

As a service to our followers, we will link below as many of the research presentations given as we are allowed to. Please check back with this page, if they have not yet been posted. Press or click a title, to access its link.

Inventions by Bio4Energy Researchers Highlighted by Royal Academy for Future Potential

Zeolite membranes for gas separation, vertical gardens and reuse of textiles to make composites. These are subjects of collaboration projects by Bio4Energy researchers who have made this year’s 100 List hosted by the Royal Swedish Academy of Engineering Sciences (IVA).

To make the List, it takes a research project deemed to have “great potential to be useful”. This usefulness is thought of as potential for commercialisation of the product or concept studied, for development of either business or methods, or for providing thought leadership.

Another key criterion is for the project leader or researchers on the project to have expressed interest in collaborating with industry or related entities to further develop their invention.

Membrane technology for gas separation in use, tends to be bulky, energy intensive and cost a lot. Bio4Energy researchers Jonas Hedlund and Liang Yu are perfecting and developing ultra-thin zeolite membranes that take up less space and use less energy to perform the separation. These membranes would provide a large cost reduction if rolled out on a large scale, according to the scientists.

With Vertisà Ltd, Rosario García-Gil and team propose a module vertical garden that can be added onto the exterior of a house and mimics a natural ecosystem. Complete with a built-in watering system, which has been patented, it is not only designed to help with greenhouse gas capture in cities, but also serves to insulate and beautify the wall it is attached to. The module is both low-technology and low cost, according to the project leader.

A new process has been invented, which allows for reuse of scrapped textiles as a component in a new, strong type of composite material based on a mixture of discarded textiles and plastics. Kristiina Oksman and co-workers used a piece of process equipment called extruder, to mix the cut fabrics with plastics. The resulting composite is two fifths textiles and costs less than the standalone plastic polymer.

Three-year Project Could Set Steelmaker Well on Way to Hydrogen-based Operations

Industry and academia are teaming up to enable a phase out of fossil fuels in Sweden-based steelmaking industry. Steelmaker SSAB will be collaborating with Luleå University of Technology (LTU) and the metal industry’s research institute Swerim.

After many years of preparatory work, and a multitude of projects, nearly SEK50 million (€4.1 million) will be invested over three years by the European Union and the Swedish Agency for Economic and Regional Growth, according to a press release from LTU. The feasibility of using biogenic carbon sources in hydrogen production is already being demonstrated in studies by Bio4Energy scientists and others.

However, the present project could give the industry a decisive push in laying bare an efficient and economically viable path ahead for transitioning from fossil coal to “green” hydrogen, using biocarbon.

“We [want to arrive at] the best way possible to implement biomass into the flow of steelmaking… We have to make an optimal overall process: An optimised value chain as a whole”, said Kentaro Umeki, professor at LTU Energy Technology.

Four Bio4Energy research leaders are involved. Umeki and Fredrik Granberg are experts at thermochemical conversion of biomass, while Joakim Lundgren and Andrea Toffolo will be collaborating with others to assess biomass availability and possibly also where best to localise facilities geographically for its pre-treatment.

“The industry wants to scale up. This is a push from them. They have several years to build a full-scale plant. They are discussing with engineers” about the way in which to go about it, Umeki said.

The overall project is called FINAST, which is the Swedish acronym for Research and Innovation in Norrbotten for Advanced Green Steel Production and Manufacture. It is headed up by professor Jens Hardell at LTU Machine Elements.

“I think that the FINAST project is a fantastic example of Bio4Energy and CH2ESS joining forces”, said professor Lundgren; with reference to LTU’s Centre for Hydrogen Energy Systems Sweden. It has the aim to integrate production, storage and transport of hydrogen in an optimal way and includes process integration in relation to the electrical power system.

Breakthrough Innovation: Hydrogels from Norwegian Kelp to Be Commercialised

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 Hyperborea.

“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.
