Bio-based Water Filtration, Electrodes Expected Output of EU Project on Smart Use of Biomass Residue

13 November, 2024/in News/by Anna Strom

Bio4Energy researchers and partners are laying the groundwork for making water filtration devices and electrodes for energy storage devices, from residual biomass materials that are currently in excess.

The main product used in this project is activated carbon and the technology used for the transformation of biomass into biochar is pyrolysis. Biochar is a brittle and porous carbon-rich product with coal-like qualities, which is being studied and used in water purification and soil remediation.

The main product used in this project is activated carbon and the technology used for the transformation of biomass into biochar is pyrolysis.

Pyrolysis is a thermochemical technology, in which a biomass starting material is exposed to very high temperatures inside a closed reactor void of oxygen or almost. The idea is to arrive at a dry and porous product through thermal and chemical alteration; but without burning the biomass to ashes.

Drawing on funding from the European Union, via its Interreg Aurora programme—allowing EU and associate nations to come together in regional constellations to tackle issues jointly in areas such as environment, health, research and education or energy—Alejandro Grimm and Francesco Gentili are heading up a multi-stakeholder project.

Wider aim of reusing residual biomass materials that are in excess

While the aim is to make product prototypes for bio-based water filtration devices and electrodes, the project has a wider scope of investigating and finding environmentally sound uses for residual streams of biomass from the forestry industry, agriculture, biogas making and aquaculture. The latter part targets aquatic biomass such as macroalgae from the Baltic sea and microalgae used in the treatment of municipal sewage water.

“The idea is to use residues from forestry, the pulp and paper industry or aquaculture to use pyrolysis to purify water and to produce supercapacitors to create various applications”, according Gentili, researcher at the Swedish University of Agricultural Sciences (SLU). A capacitor is an electronic component that stores electric charge. The term supercapacitor signifies a capacitor that has superior power density.

“The idea is to use residues from forestry, the pulp and paper industry or aquaculture to use pyrolysis to purify water and to produce supercapacitors to create various applications”.

In certain cases, the recycling and reuse of biomass materials are performed in multiple stages. In one work package, the researchers have teamed up with regional utilities and a business operator; first to make biochar from biomass residues and manure and then adding the biochar in the retting mixture underpinning biogas production, thereby adding a needed source of carbon.

Bio-based graphite is a target product

In others, the aim is to identify suitable biomass residues for making alternatives to petrochemically-based product applications. One such example would be graphite, which is high in demand not least because of its use in smartphone batteries. Graphite is a soft, dark grey form of carbon; also used in pencils, machines and nuclear reactors.

“We are designing bio-based graphite that resembles the fossil [kind] but the synthesis process is environmentally friendly and the final product functions in just the same way as fossil one”, said Grimm, SLU researcher who leads a Nature Refines project within the larger Interreg Aurora scheme.

While there are various timelines for the latter, the Nature Refines project runs until autumn 2026. By then, the pair expects to have a prototype of a water filtration device to show that can wean wastewater of heavy metals using microalgae from Gentili’s algae development site at regional energy utility Umeå Energi.

“We can offer a filter of higher quality than those imported from China”, Grimm said, referring to water filtration products currently available in do-it-yourself hardware stores in Sweden.

“The idea is to make sure that we use residues that are qualitative and fit for purpose”, Gentili added.

Activated carbon (AC), also known as activated charcoal, is a rough, imperfectly structured kind of graphite. It has a wide spectrum of pores of varying sizes, from obvious fractures and fissures to molecular dimensions. Because of its significant surface area, AC is frequently used for a variety of purposes, including removing impurities from air and water. Small, low-volume pores that are present in AC enhance the surface area that is accessible for chemical reactions such as adsorption (which is different from absorption).

Giant Park for Development of Bio-based Products, Materials, Opens in Northern Sweden

14 October, 2024/in News/by Anna Strom

Development park Bioeconomy Arena opened today, at Örnsköldsvik in northern Sweden.

It is a 2,400 square metre park for development of products and materials from bio-based input material, such as residue from forestry operations or bio-based waste from pulp and paper making.

Processum Biorefinery Cluster, Bio4Energy’s strategic collaboration partner, stands host to the Arena. It is part of an industrial development called Domsjoe Development Area. Its centre player Domsjö Fabriker is a full-scale biorefinery, owned by Aditya Birla Group of India.

“Sweden’s most interesting environment for development of bio-based products and materials is taking a large step forward. Together, we represent the entire value chain from research to industrial production”, said Emil Källström, CEO at SEKAB, a company in the Bio4Energy Industrial Network, based at the development area.

In September 2022 the mother company RISE Research Institutes of Sweden inaugurated the first leg of a large investment in biorefinery test beds nationally, with Piteå and Örnsköldsvik as hubs for biorefinery pilot and demonstration facilities.

“Here large companies will meet tech companies in expansion and create new possibilities”, said RISE CEO Malin Frenning, referring to Bioeconomy Arena.

“The pilot hall… also has the potential to attract international firms that want to place new research units in the creative environment here”, Frenning said.

Large Project Granted for Making Affordable Bio-based Plastics, Using Algae as Feed

1 October, 2024/in News/by Anna Strom

A consortium of Bio4Energy researchers has scored a grant for developing bio-based plastic to deliver prototypes of consumer products by project end, three years from now.

It involves a number of industrial and business partners who will provide either facilities and input material for experimental trials or develop consumer products, such as lampshade prototypes and a foam to go into packaging materials, respectively. The resulting products will be tested for their biodegradability.

It involves a number of industrial and business partners who will provide either facilities and input material for experimental trials or develop consumer products, such as lampshade prototypes and a foam to go into packaging materials, respectively. The resulting products will be tested for their biodegradability.

Global plastics production has exploded since the early 20th century and virtually all of it derives from fossil-based petrochemicals. In 2018, it stood at 359 million metric tons per annum.

At the end of life, over three fourths of plastics go into landfill. The breakdown of plastic made from petrochemicals generally takes hundreds of years and comes with leakage into the environment, especially for the kinds that degrade to microplastics during the composting process.

Plastic pollution has become an urgent global problem.

Innovation-to-consumer product value chain

In northern Sweden, Bio4Energy experts on the development and use of algae biomass for products and applications are proposing to tackle the issue head on by linking up actors in a research innovation-to-consumer product value chain.

The Swedish Energy Agency—which is not only a government agency, but also a research funder—has agreed to part sponsor the development of more affordable polyhydroxyalkanoate (PHA), which is a type of bio polyester that has the moldability of traditional plastics.

So far, PHA as a plastic alternative has had limited uptake, mainly because of the high cost of the feed for bacteria that make it. Here is where the Bio4Energy research comes in.

The scientists will identify strains of microalgae which, using sunlight and carbon dioxide, make biomass that the bacteria like to eat. The algae themselves will feed off industrial flue gases and wastewater produced at premises of regional energy utility Umeå Energi, which the green algae help clean during the while.

The scientists will identify strains of microalgae which, using sunlight and carbon dioxide (CO₂), make biomass that the bacteria like to eat. The algae themselves will feed off industrial flue gases and wastewater produced at premises of regional energy utility Umeå Energi, which the green algae help clean during the while. The project also involves a utility that delivers drinking water, as well as handles sewage water treatment and waste recycling in the greater Umeå area; Vakin.

Algae research expert Christiane Funk will lead the project from Umeå University (UMU) and collaborate with Francesco Gentili, Swedish University of Agricultural Sciences (SLU), whose team operates development facilities at the Umeå Energi Dåva site. His colleague Carmen Cristescu will perform a life cycle assessment of the process. Bio4Energy programme manager Leif Jönsson’s group at UMU is also part of the project.

“We are going to use algae as feed for bacteria producing PHA, a type of bio polyester. The bacterial cultivation will be scaled up to litres by RISE Processum”, professor Funk said.

Membership company Processum at RISE Research Institutes of Sweden is one Bio4Energy’s strategic partners. Bio4Energy alumnus Pooja Dixit will lead this part of the work.

High cost of PHA limits market uptake

PHA as an alternative to petrochemical polymers for plastic production has had limited market uptake because of its high cost.

“It would be perfect to use PHA instead of plastic. We try to make it cheaper so that PHA can compete with fossil-based plastic and we also try to make the process more sustainable by using microalgae. We have to test which bacteria like which type of sugars [or carbohydrates] to produce PHA”, professor Funk said.

Downstream, two companies stand ready to turn the PHA into products.

In Stockholm, Interested Times Gang will take PHA from the project, to attempt 3D printing lampshades.

SME Cass Materials at Örnsköldsvik aim to mix the PHA with starch to improve an existing form of packing material in terms of its environmental footprint. The company describes the material as a “next generation bio-based foam that is lightweight with good mechanical strength and insulation properties for the packaging industry”.

Finally, Biocompost of Skellefteå is going to test the materials produced, particularly the ones that have a starch component, to see how long they take to biodegrade.

“We are going to work on the microalgae and the bacteria… and feed the carbohydrate to the bacteria in a two-step process”, Funk explained;

“We are going to test different algal strains [to ascertain] which produce the best feed for the bacteria”.

Globally, nine per cent of plastic waste is recycled and 12 per cent is incinerated. In countries that have ocean shorelines, each year between 4.8 million and 12.7 million metric tons of plastic waste are discarded into the sea. Source: Encylopaedia Britannica.

Project title: Waste2Plastic – Circular economy, recycling of CO2, nitrogen, phosphorus and water for bioplastics in a sustainable society

Funders: Swedish Energy Agency’s strategic innovation program RE:Source, which focuses on developing circular and resource-efficient material flows that are within planetary “boundaries”. The joint contribution of industrial partners is expected to match the SEA grant.

May We Tell You About Bio4Energy Advisory Board?

3 September, 2024/in News/by Anna Strom

The Bio4Energy Advisory Board, made up of ten distinguished representatives of the bioenergy and biorefinery sector in Sweden, was designed as a sounding board to the Bio4Energy Board and programme managers whose joint task is to administer and monitor the agenda of the research environment and its funding.

It met at Örnsköldsvik, Sweden this week to learn about the giant pilot hall being set afoot at the Domsjoe Development Cluster. On the cards for the new Bioeconomy Arena are 130 – 150 test beds for trial running and evaluating bio-based processes in increasingly large steps up to near industrial level.

Bio4Energy Advisory Board and guests met at Örnsköldsvik, Sweden this week to learn about the giant pilot hall being set afoot at the Domsjoe Development Cluster. On the cards for the new Bioeconomy Arena are 130 – 150 test beds for trial running and evaluating new bio-based processes in increasingly large steps up to near industrial level.

Pulping, chemicals, carbon capture and storage, carbon capture and use, as well as industrial biotechnology; will be the focal areas of this site for testing and scale up of bio-based innovations.

The fact that the Advisory Board is an internal and a consultative body, has come to mean that input to its discussions are not shared publicly. However, its mission is.

“I like the idea of the Advisory Board, if it is used as intended from the start: As an advisory body to the researchers’ agenda”, said Peter Axegård, who has been a member from the start five years ago.

“I take part to learn about what you are doing and enjoy [following] the development of young researchers. New knowledge and motivated researchers [are] what matters most to me”, he added.

Axegård has held a string of leadership positions in the sector, including at partner institutes to the current RISE Research Institutes of Sweden. Today he serves as CEO of a startup in the sector, FineCell; where they develop a process for the production of nano cellulose called CellOx.

Bio4Energy Industrial Network

At the start of Bio4Energy, the academic leadership fostered close links with an industrial network of companies and regional level organisations that either promote or contribute directly to developing a bioeconomy for Sweden. Most of these organisations are still cherished collaboration partners to the approximately 225 Bio4Energy researchers.

However, because the research environment and its agenda have been steadily growing, it was thought necessary to bring a different structure to the links with and input from industry and the sector.

The Bio4Energy Advisory Board was drawn together with the aim of forming a consultative body to the Board of the research environment, with deep knowledge of the corresponding industrial sector.

New Stride in Wound Healing Expected, as Researchers Add New Material for Medical Dressings

29 August, 2024/in News/by Anna Strom

On the back of successfully introducing sea kelp as a base material for hydrogels used in wound healing—and selling the rights to Norwegian firm Alginor ASA—Bio4Energy researchers are back with a deep-dive into making medical dressings for complex or chronic wounds. This time, the base material will be made from woody residues from trees.

Linn Berglund of Luleå University of Technology received a grant from national trade union Swedish Forest Industries, official voice of the sector, to place woody residues as the base material of choice in the treatment of wounds that require a certain level moisture to heal, but need to be rid of excess liquid formed at various stages of the healing process.

Based on a series of pre-studies, she will be using nanotechnology to make networks of wood fibres that hold just the right amount of moisture at the base of the dressing, which will have a transparent overlay.

“We are moving one step closer to the perfect wound dressing. We already have promising results with dressings that take up a lot of excess liquid in moist environments”.

“We are moving one step closer [to the perfect wound dressing]. We already have promising results with dressings that take up a lot of excess liquid in moist environments”, according to Berglund, researcher and long-standing member of Bio4Energy’s team of experts at nanotechnology.

“When it comes to burns for example, the liquid should be transported away, not closed in”, she added.

The efficacy of the nanofibre network, together with the transparent top part, should allow for the healing to be monitored without the need for frequent changes of the dressing.

“The transparency of the material creates unique possibilities”, Berglund told Bio4Energy Communications.

The project will run at least until the end of next year. By that time, the researchers expect to know more about the way in which the dressing materials react at various degrees of swelling due to liquid retention. We are talking about characterisation down to nano scale.

“We are going to use atomic force microscopy [coupled with] trials enabled by new equipment for rheology measurements”.

Atomic Force Microscopy is a very-high-resolution type of scanning probe technique, with resolutions in the order of fractions of a nanometre, according to Wikipedia.

Other legs of the set up include life cycle assessment studies to check the environmental impacts; not only of the wound dressing at the end of life, but also of the production. Moreover expensive chemicals are used in the production. The researchers are going to look for ways to reduce the chemical input while obtaining similar results.

The grant is part of a Young Researchers Award, awarded in spring of this year, with funding from a Gunnar Sundblad Foundation.

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

5 July, 2024/in News/by Anna Strom

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

17 June, 2024/in News/by Anna Strom

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 operating 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 of 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

10 June, 2024/in News/by Anna Strom

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.

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

25 April, 2024/in News/by Anna Strom

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”.

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

1 February, 2024/in News/by Anna Strom

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.

“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.
