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

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.

Pioneering Work to Study ‘Forever’ Chemicals PFAS Targets Wastewater Treatment in Incineration Plants

Backgrounder. Over the last decade, environmental chemists aiming to map and close the loop on toxic chemicals in the handling and incineration of household waste, or in combustion facilities in the bio-based sector, have increasingly turned their attention to per- and polyfluoroalkyls, PFAS.

Since the 1950s, this very large group of manmade chemicals has been used in consumer products to repel water and oil. Experts are increasingly referring to them as “forever” chemicals, because of their extreme persistence in environment, and which may also spread over wide areas through contact with water.

Even though PFAS are used worldwide in detergents, cosmetics, non-stick coatings and dirt or water-repellent textiles, their fate and impact at the end of life are largely unknown.

Academia and industry in long-standing collaboration

Environmental chemists, led by Bio4Energy’s first programme manager Stellan Marklund, were leaders in the field of isolating and assessing dioxins formed as a result of operations of waste-to-energy plants.

Dioxins and dioxin-like substances, including PCBs, are persistent organic pollutants (POPs) regulated globally by the Stockholm Convention of the United Nations. POPs can travel long distances from the source of emission and bioaccumulate in food chains.

This long-standing collaboration with industry in northern Sweden, and notably with regional energy utility Umeå Energi continues with associate professor Stina Jansson of Umeå University. It draws on the knowledge obtained and infrastructure put in place to tackle the more recently seen risk of PFAS leaking to soils, air and water as a result of waste storage and incineration.

This long-standing collaboration with industry in northern Sweden, and notably with regional energy utility Umeå Energi continues with Marklund’s former student, associate professor Stina Jansson of Umeå University. It draws on the knowledge obtained and infrastructure put in place to tackle the more recently seen threat of PFAS leaking to soils, air and water as a result of waste storage and incineration.

“We do not know the fate of PFAS in waste incineration. It is a black box”, Jansson said.

Her team, however, has started tackling the problem from the ground up.

Samples taken throughout the regional combined heat and power plant at Dåva, collected by Sofie Björklund, Eva Weidemann and Alana Lansky, point to the presence of PFAS in all intra-plant waste or residual streams. In a recent scientific article, the team also shows that the common practice of supplementing household waste with digested sludge from industrial operations significantly increases the level PFAS in flue gases, ash or process water from waste incineration.

The secret may be in the water

“We know that there are considerable amounts of PFAS in waste water sludge… and have located accumulations at the water purification stage. We see froth and even foaming in the process water”, according to Jansson.

People who go out in nature may recall seeing this type of froth or foam in shallow lake waters or, in certain countries, at the exit of waste water pipes, which could be a sign of PFAS pollution.

Thanks to the encompassing work to identify, charaterise and capture dioxins in similar contexts, the scientific researchers are able to draw parallels and make educated guesses about which types of technology can be used to rein in the lion’s share of PFAS compounds that remain onsite at the end of the incineration process.

“We are working together with other researchers to understand [how and what triggers] the breakdown of these compounds”, Jansson said.

At the Umeå cluster, the researchers are focusing on hydrothermal carbonisation. Scientists at the National Aeronautics and Space Administration of the United States of America, are targeting a method that involves using plasma for the breakdown.

“We may go into collaboration with them”, Jansson added.

Other techniques being tested elsewhere include membrane technology and ozone treatment.

“Our method of testing the process water is unique… This process water can be leachate of landfills, for example. Perhaps this will be where we can stop the pollution”, Jansson said.

Sweden’s Bioeconomy Arena to Open by Early 2025: Bio4Energy Researchers Stopped by

Bio4Energy took its business to Örnsköldsvik, northeastern Sweden, last week for a glance at the large biorefinery development ventures underway.

About 50 researchers visited the Bioeconomy Arena—a large development park under construction—in the wake of the Swedish government’s pledge to invest in test beds. These are a means to realise the bioeconomy and meet goals to contain climate change.

“The start up of pilots [will take place] this autumn or early 2025”, said Karin Johnson, shepherding the Bio4Energy group at a study visit.

Johnson is CEO at Bio4Energy strategic partner Processum Biorefinery Cluster, institute partner to the companies at the Domsjoe Development Area. They include the full-scale biorefinery Domsjö Fabriker of Aditya Birla, Örnsköldsvik Energi, SEKAB, Liquid Wind, Norion and others.

The development park for biorefinery, Bioeconomy Arena on the northeast coast of Sweden, will have 130 – 150 test beds designed to test and evaluate bio-based processes in increasingly large steps up to pre-industrial level.

The Arena will have 130 – 150 test beds designed to test and evaluate bio-based processes in increasingly large steps up to pre-industrial level, according to David Blomberg Saitton, Processum.

Pulping, chemicals, carbon capture and storage, carbon capture and use, plus industrial biotechnology are the overarching focal areas, he said.

The facilities covering hundreds of square metre of purpose-made grounds, complete with access to media such as electricity, steam and water; will include a “customer” area designed for companies keen to test their process on the grounds, but without having to share patenting information with Processum staff technicians, Johnson revealed.

Companies will have access to rental space to test a container-based process, she explained.

In connection with the study visit, Bio4Energy hosted its biannual Researchers’ Meeting. Impressions of the event, below, are courtesy of our scientific and institute researchers, as well as their students. Without them, there would be no research environment Bio4Energy.

In his PhD thesis, researcher Martin Plöhn lays out a scheme for wastewater treatment using microalgae. Photos by Anna Strom and Umea University photographers.

Microalgae that Thrive in Cold Climate Clean Wastewater, Give Biomass for Renewable Plastics

A research report—covering five years of investigations—shows that microalgae grown in cold and dark conditions may not only be made to thrive on their own, but also remove the heavy metal content of industrial wastewater that conventional treatment plants do not filter out.

The high performing algal strain selected also turned out to produce ample carbohydrate biomass suitable for making bio-based plastics.

The academic research team behind the findings is based in northern Sweden; where winters are long, cold and dark. However, the cluster—including the research environment Bio4Energy and the MicroBioRefine project—have some of Scandinavia’s leading scientists in the field of developing biomass from blue-green algae as a renewable input material for making products.

The research report, by recent PhD graduate Martin Plöhn, will be released by Bio4Energy’s lead partner Umeå University as soon as details of its major findings have been cleared for publication in the chief biotechnology journal of a well-known publisher.

The researchers have identified a common and locally available strain, Chlorella vulgaris, as a top performer among microalgae when it comes to cleaning wastewater of cadmium, copper and lead. There was no additional source of energy or lighting added.

In a nutshell, the researchers have identified a common and locally available strain, Chlorella vulgaris, as a top performer among microalgae when it comes to cleaning wastewater of cadmium, copper and lead. The process has been tested in a research laboratory. There was no additional source of energy or lighting added to indoor room temperatures, daytime indoor (fluorescent) lighting and natural daylight.

Cleaning with microalgae after conventional wastewater treatment, to meet legal standards

Turned into a fully-fledged technology, the scheme would allow industries whose activities leave substantial amounts of wastewater in their wake, to shave the last one-to-two micrograms of heavy metals off wastewater already treated in a conventional treatment plant. The scheme comes with optional provisions for reuse in industry of the heavy metals thus recycled.

“Our microalgae can be used to treat wastewater to remove pollutants and produce freshwater…. We do not want to replace the conventional treatment system, but come in at the end and take away the heavy metal content that is still higher than the law”, doctor Plöhn told Bio4Energy Communications.

“Our microalgae can be used to remove pollutants and treat wastewater to produce freshwater… We do not want to replace the conventional treatment system, but come in at the end and take away the heavy metal content that is still higher than the law”.

In the second part of the microalgae project, Chlorella vulgaris again outperformed other strains tested when it came to producing polyhydroxybutyrate (PHB), a type of plastic, via bacterial breakdown of the biomass. The process has been tested in up to 25 litres of wastewater at a time, in a research laboratory.

Checking for unwanted emissions and scaling up

After successful proof of concept trials, the researchers have received expressions of interest for testing the concept on a larger scale from Bio4Energy partners at the RISE Research Institutes of Sweden. Plöhn and colleagues now are looking for industrial partners.

“We are looking for people who could be interested in the forest industry, with the message that we can add value… to existing processes”, he said.

The researchers collaborate with colleagues at the Swedish University of Agricultural Sciences to perform life-cycle assessment studies; to double check that their concept is sustainable in terms of minimising greenhouse gas emissions. Technically, the algae consume carbon dioxide down to net zero, but the researchers want to make sure that the system is water tight.

Dissertation in hand, Plöhn is not about to finish working on the project anytime soon. The microalgae also produce lipids and protein. Moreover there is the bio fertilizer route that remains to be explored.

“I see opportunities to explore this concept beyond carbohydrates. There will always be wastewater that needs to be treated. We need to use what we have right now”, he said.

Since late March Plöhn is a staff scientist at Umeå University and industry representatives are invited to contact him and the research team there for at least another nine months.

Seeing Possibilities: Meet Bio4Energy’s Coordinator for Swedish funder BioInnovation

Bio4Energy’s new coordinator for BioInnovation, Swedish funder of bio-based innovations, is Ulrika Rova, professor at Luleå University of Technology.

Rova sees herself not only as the research environment’s representative with an overview of possibilities for applying for funds, but also as a facilitator and a bearer of information to potential collaboration partners representing other organisations in the bio-based sector.

“I need first to study the offer and future calls for projects, but then I can be a channel for information going both ways”, Rova told Bio4Energy Communications.

Structured as a member organisation, BioInnovation evaluates and funds a range of projects on behalf of the Swedish national funding agencies Vinnova, Formas and the Swedish Energy Agency. Bio4Energy is a founding member, or a “party”, and involved in its divisions on Materials, as well as Chemicals and Energy.

Structured as a member organisation, BioInnovation evaluates and funds a range of projects on behalf of the Swedish national funding agencies Vinnova, Formas and the Swedish Energy Agency. Bio4Energy is a founding member, or a “party”, and involved in its divisions on Materials, as well as Chemicals and Energy.

“Our vision is that Sweden will have transitioned to a circular economy by 2050. We are going to create optimal conditions for developing the Swedish bio-based sector and create sustainable solutions for a global market”, the Swedish version of BioInnovation’s website said (ed’s translation).

Two projects headed up by Bio4Energy research leaders stand out: Joint production of edible mushroom and advanced biofuel, as well as production of food-grade prebiotics from forest resources and sea squirts, a colonial tunicate.

The latter is a small sea-living invertebrate that has an outer protective cover; a tunic consisting of a cellulose-like substance; which is the target for developing prebiotics for human and animal consumption.

Rova led the prebiotics project. Given that Bio4Energy is a member since 2015, I want to know what might promote a more high-profile participation in BioInnovation-funded projects.

“The requirement of 50 per cent co-funding by proprietary users, that is an industrial partner, could be perceived as a challenge. As an [academic] researcher, you need to have a good contact network in industry”, Rova said.

“I will be participating the annual and biannual meetings and provide an overview of possibilities going both ways”, she said.

Professor Ulrika Rova is a veteran member of Bio4Energy. She served as deputy director of the research environment during its second five-year mandate, ending in 2019. Instrumental in developing education and training, she was the first head of the Bio4Energy Graduate School. She is a senior member of one of Bio4Energy’s research platforms, Biopolymers and Biochemical Conversion. Her home organisation is Luleå University of Technology where she is part of a Paul Christakopoulos' research group specialising in biochemical process technology. In later years, the group has been focusing on carbon dioxide capture and reuse, as well as bioprocesses for upcycling of plastics and managing EU projects.

Spin-off Wins Prize for ‘Great Potential’ of Plant Nutrition Products with Minimal Footprint

A university spin-off headed up by Bio4Energy researchers and partners have won a prize for the “great potential” of their innovative technology that helps new tree or agricultural plants take root, while drastically reducing negative impacts such as nutrient runoff to ground water, acidification and greenhouse gas emissions, compared with conventional fertilizers.

Arevo of Sweden markets products based on the amino acid arginine, which either is used for cultivating plants in pots or cassettes (liquid product) or stimulate growth of new roots to enhance establishment when planted in the field (granular product).

This new way of doing plant nutrition is different from the established route of planting and adding fertilizer based on ammonia and nitrate, which has well-known environmental and ecological impacts.

“This innovation tackles global challenges… and provides a solution that is revolutionary but simple”, according the jury of Umeågalan, an annual celebration of “collaboration across borders” in northern Sweden, hosted by the Municipality of Umeå.

“By combining strong research and substantial competence with a great vision for the future, the winner has great potential to continue to develop current and new markets”, the prize motivation said.

The company and its product range are built on research findings by professor Torgny Näsholm of the Swedish University of Agricultural Sciences and colleagues, who set in motion a paradigm shift in plant science in the late 1990s.

In an article in the prestigious scientific journal Nature, they showed that seeds and seedlings take up amino acids directly, which produces a growth spurt including the establishment of solid roots and diminishes the amount of stress on plants and their ecosystem.

In the years after the initial discovery, Näsholm and colleagues showed that arginine is a preferred nitrogen source for plants such as conifer seedlings. In fact, together with partners they went on to file patents on their innovation, targeting arginine for their technology. The rest is history.

“The great advantage is efficiency and better use of resources”, Näsholm said of the new technology.

“When in plant cultivation, you always need a good start. This is a way to render effective the way in which plants use their resources for growth”, he added.

Large forestry companies, forest owners and their regional trade union are using Arevo’s products. Holmen was first out.

Näsholm sees expansion as being on the cards; with possible new markets to conquer in Finland and the Baltics, as well as new segments in Sweden such as greenhouse owners and individuals interested in growing their own produce.

Whatever the case, he welcomes the prize.

“It is nice to be noticed”.

New leader for Feedstock Pre-processing Eyes Critical Raw Materials as New Direction for Research

Bio4Energy’s smallest research platform has a new leader with a grand vision.

Mikael Thyrel of the Swedish University of Agricultural Sciences (SLU) has been a member of the research environment since the outset in 2010.

In fact, he first joined the laboratory of Bio4Energy’s first programme manager, professor emeritus Stellan Marklund of Umeå University. There, Thyrel rose to increasing responsibility and, in 2009, shifted to SLU to become a PhD student with associate professor Torbjörn Lestander.

Today he is not only a university lecturer, but also head of department at SLU Forest Biomaterials and Technology. His colleagues may know him as a coordinator for the Sweden-based synchrotron Max IV Laboratory for very high-tech X-ray laser research.

Although his specialty is biomass spectroscopy, Thyrel’s vision for the work on the Feedstock Pre-processing platform is much greater.

“Our platform serves the rest of Bio4Energy by designing different types of fractionated biomass. It is mostly about applied research in the area of pre-treatment”, he told Bio4Energy Communications in an online interview.

“However, we may shift our focus. We could [turn our attention to] critical raw materials, such as graphite, to make the technique sustainable and available locally.

“We have been building an electrochemical lab… where we develop biocarbon materials for use in batteries or adsorbents. We are looking at functionality and surface chemistry”, Thyrel said.

The platform would continue to rely on the Biomass Technology Centre, the university’s off-campus development facility that is always teeming with life, as technicians and scientists work hand in hand to deliver dried, fractionated or pelletised materials to customers in industry. New coordinator there is Magnus Rudolfsson, researcher.

Greatly appreciated by his colleagues, Thyrel clearly is one of those die-hard Bio4Energy members whose enthusiasm never seems to fade neither for the small wins of research progress, nor the big ones of making Sweden a leading light when it comes to designing and developing bio-based technologies that can help phase out the fossil economy.

Now he has become a platform leader in the Bio4Energy research environment.

“It feels great. Our efforts are so timely, given what is going here [in northern Sweden]. It is an industrial revolution!”, according to Thyrel.
