Breaking Down Benefits of Using Brilliant X-ray Light to Know Bio-based Materials: Workshop

20 November, 2024/in News/by Anna Strom

Bio4Energy scientists and partners are offering an opportunity for researchers to learn more about the benefits of applying for time to make experiments aided by brilliant X-ray light, at so-called synchrotron facilities, to study the inside of materials.

The partners are hosting a workshop 27 November at Umeå, Sweden; both for on-site and online participation. Sweden, where the scientists are based, is host to the world’s first fourth-generations synchrotron, the MAX IV Laboratory at Lund.

Synchrotrons are machines—giant particle accelerators—imagined as a tool for advancing science beyond what the forefathers of science deemed possible. With the aid of specialised staff, guest researchers can have a material that they want to know X-rayed with powerful light beams to the point of literally knowing it inside out.

With the aid of specialised staff, guest researchers at synchrotrons can have a material that they want to know X-rayed with powerful light beams to the point of literally knowing it inside out.

“Synchrotrons are very much like Swiss army knives, but the various tools attached utilise the brilliant X-rays for almost all kinds of X-ray-based measurement techniques”, according to Nils Skoglund, associate professor at Umeå University.

“Each experimental station has [its] own set-up and is called a beamline, where there is great expertise in the specific analysis performed within the beamline staff”, he added.

The research environment Bio4Energy has two experienced synchrotron research coordinators in its ranks. Skoglund leads the research platform Environment and Nutrient Recycling, while Mikael Thyrel heads up Feedstock Pre-processing. Thyrel is also head of his university department at the Swedish University of Agricultural Sciences.

Endless possibilities for study and observation

From Skoglund’s platform, researchers have used beamline time thoroughly to investigate oxidation states of certain elements inside nutrient-carrying materials. They drew on the Balder beamline at MAX IV, for this undertaking. At DanMAX beamline they looked at the distribution of crystalline phosphates in 3D, for biomass ash and biochars. Biochar is charcoal, sometimes modified, that is intended for organic use, as in soil, says Wikipedia.

“These are just some examples of how Bio4Energy researchers utilise our large-scale research infrastructure where we are awarded beamtime in international competition”, Skoglund said.

As the name of his research platform suggests, Skoglund scientific focus is nutrient and resource recovery from the energy sector. The team at his laboratory design renewable fuels and, by doing so, aim to alter the quality of ash remaining from combustion or gasification of biomass.

Whereas the scientific community has spent decades debating whether biomass ash should be ‘brought back’ to forest soils as a fertilizer, Skoglund has remained steadfast in his replies to Communications that it depends what is in the ash.

“Even though the goal is common, the desired fuel blend compositions are likely different for the forestry sector, agricultural sector, and waste streams from society”, he cautions on his university researcher’s profile.

As far as synchrotron research goes, Skoglund recommends a book by Swedish professor Jan-Erik Rubensson with the title of, Synchrotron Radiation – An everyday application of special relativity;

“So, it is not really correct to identify a specific type of research that could be conducted at a synchrotron—it is more about what phenomenon you want to observe with the brilliant X-ray light available”.

Water Filtration, Electrodes Expected from 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 filters and electrodes for energy storage devices, from residual biomass materials that are 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).

Researchers to Map Composition of Green Algae, Pave Way for Biotechnology Breakthroughs

4 November, 2024/in News/by Anna Strom

Bio4Energy’s research team dedicated to creating applications from green algae have won funds to investigate the composition of cell walls in microalgae. These are microscopic algae that are not visible to the unaided eye, used to produce algal biomass for use in biotechnology applications.

Christiane Funk and students at Umeå University, Sweden hope to develop much needed information on the mechanisms that govern buildup and breakdown of the cell wall in these Chlorophyta algae, with the aim of allowing researchers worldwide more easily to design biotechnology applications that are cost and energy efficient.

Last week, national funder Swedish Research Council – VR announced its decision to support a four-year project.

The researchers aim to find out which enzymes are involved in making the cell wall mouldable and the way in which this plasticity enables – or could enable – the green algae to cope with environmental stressors. They also aim to map the transport of carbon, which is known to fluctuate, inside the cell.

With this knowledge in hand, they want to look into ways to manipulate the cell wall for better outcomes in the design of biotechnology applications.

“This proposal aims to address a critical gap in research, by investigating the biosynthesis and modification of the cell wall of Chlorophyta microalgae. We will gain insights into the molecular mechanisms underlying the microalgal cell wall, its plasticity and perception of the environment”.

“Despite their promise as a sustainable feedstock for biotechnological applications, the use of microalgae has been hindered by high monetary and energy costs associated with the processing steps that follow cultivation, particularly the harvesting of algal biomass and extraction of valuable compounds”, Funk and colleagues wrote in their project application;

Over the last decade, Bio4Energy’s research teams studying microalgae have worked diligently to lay a foundation for production, scale up and demonstration of algal biomass for use in consumer products and as an agent in water purification in industrial facilities.

The two teams focus on green and blue-green microalgae, respectively. Francesco Gentili and colleagues, Swedish University of Agricultural Sciences, run development facilities in collaboration with regional energy utility Umeå Energi, at Dåva just off Umeå, in northern Sweden.

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.

PhD Student Wins Prize for ‘Outstanding’ Work to Capture Micropollutants

5 June, 2023/in News, Uncategorized/by Anna Strom

A Bio4Energy PhD student at Umeå University (UmU) has won a prize for his work on waste management, bio-based materials and recycling, by a Sweden-based institute that represents his home country, France.

In his research, Pierre Oesterle investigates ways to re-use by products from forestry industry; and the ways in which these can made to remove micropollutants from wastewater.

In doing so, Oesterle is one of the forbearers in the field of bio-based chemicals and materials, who aim to tackle the rapidly expanding problem of micropollutants that leak into the environment as a result of pharmaceutical drug use.

For the most part, this kind of pollution is not being picked up and filtered out by current wastewater treatment plants.

Using sorbents for treating wastewater is not new in itself, but the ones on the market are based on activated charcoal. In a context of aiming to contain climate change, such materials are not deemed environmentally friendly.

A sorbent–whether based on petrochemicals or biomass–is a material that acts as a molecular sieve, which attracts micropollutants and holds them to it, in a layer of thin film.

“My research tries to design bio-based activated biochars from waste of mining and forestry industry to replace those activated carbons in wastewater treatment plants”, Oesterle writes in an e-mail to Bio4Energy Communications and; “to regenerate or recycle these spent sorbents using hydrothermal deconstruction.

“The idea behind this technology is to use a low temperature, but a high pressure; to degrade the contaminants adsorbed on the surface of the activated biochar and to check the regeneration efficiencies of the material afterwards”.

Circular economy

The French Institutes of Denmark, Estonia, Finland, Norway and Sweden in their Nordic Award 2023 are targeting “outstanding achievements” to pave the way for a circular economy, by young French nationals.

“This award aims to promote cultural and scientific cooperation between France and the Nordic countries and to reward the outstanding achievements of young researchers”, according to the call for applications.

Oesterle will receive his prize from the hand of the French Ambassador to Sweden, 20 June. It comes with a paid-for trip to meet likeminded colleagues in the French region of Auvergne-Rhône-Alpes, so that more cross-border and circularity friendly research may be spawned.

This edition of the FINA prize aims to help achieve three of the United Nation’s Sustainable Development Goals (SDGs): Sustainable consumption and production, climate change abatement and zero hunger.

“Few removal [or] degradation processes are currently used, such as ozonation or activated carbon. The drawback of using activated carbon is the unsustainability of the technique; as when the adsorbent is spent, most of the activated carbons end up incinerated or in landfill; inducing potential secondary pollution. Moreover, most activated carbons are based on non-renewable resources (coal), which do not meet the SDGs”, Oesterle wrote.

Event: Webinar via Zoom, in which the FINA finalists present their research, hosted by the French Institute of Sweden. Thursday June 8, from 1:30 p.m. All welcome to attend.

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

12 April, 2023/in News/by Anna Strom

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”.

Bio4Enery Going Strong: New Scientists, Collaborations

20 June, 2022/in News/by Anna Strom

Bio4Energy scientists and advanced students met at Umeå, Sweden, ready to form new research collaborations.

Bio4Energy’s most recent platform leader, Nils Skoglund, opened up for collaboration with Environment and Nutrient Recycling; and with his team presenting new lines of research.

New Bio4Energy researchers, bringing the membership count to 225, took the stage; pitching and matching.

The research environment is stronger than ever, taking its collaborations, as well as own education and training to new levels.

Moreover, expect news in terms of Bio4Energy’s outreach and online presence to follow in the third or fourth quarter of this year.

Change of Leader at Bio4Energy Environment, Nutrient Recycling

16 March, 2022/in News/by Anna Strom

The research and development platform Bio4Energy Environment and Nutrient Recycling has a new leader as of March 2022.

Nils Skoglund, associate professor at Bio4Energy host Umeå University, is taking over the platform leadership from Stina Jansson, who has the same title and affiliation, as she takes on more responsibilities for her home department.

The appointment has the blessing of the Bio4Energy Steering Group and Board.

“I am happy to take on this role and look forward to shouldering the responsibility”, Skoglund said.

As all seven Bio4Energy R&D platform leaders, he has a substantial science background; including in Chemistry, Biology and Earth Sciences; and holds a PhD in Energy Technology with specialisation in Thermal Process Chemistry. One of his focal areas is the recovery of phosphorus from biomass ash or organic waste.

He welcomed the confirmation of the continued funding by the Swedish government of the Bio4Energy research environment, which will continue at least until 2024. This would allow the platform to focus its work on medium-term goals, he said.

“I want to prioritise allowing our PhD students to attend at least one international conference each, to let them see the bigger picture of their research and allow them to meet colleagues who are interested in the same thing as themselves”, according to Skoglund.

“For a young researcher, this is important to promote the feeling that he or she is making a contribution”, he explained.

When it came to the research, Skoglund said he was keen for the platform to work focusedly to provide such scientific information that politicians could use to make decisions.

“I want us not only to develop facts and figures, but also to put them together in such a way that they can serve as a basis for decision-making”, Skoglund said.

In the last decade, the research collaboration on the platform has gone down three main avenues. They are the recovery of phosphorus, elimination of organic pollutants and nitrogen use; across the main biomass-based starting materials and their use. In the case of Bio4Energy, these latter are wood and forestry residue, industrial waste and microalgae.

For her part, the outgoing platform leader Jansson has been well-liked by her colleagues and credited with upholding a fruitful climate for discussion during her mandate.

“Changing platform leaders is a sign of health, as it changes the dynamic on the platform and things get looked at with fresh eyes”, said Jansson as she handed over the platforms reins—which took the form at the photo shoot of a relay baton axed from a tree branch—after four-and-a-half years in office.
