The research done in the group focuses on sustainable innovation, specializing in the valorization of diverse biomass sources, including forestry, agri-food, algae, and microbial origins. Our research emphasizes the use of green extraction techniques and fungal biotechnology to convert biomass into high-value molecules. These biomolecules find applications across various industries such as food, feed, cosmetics, biomedical, and materials, driving advancements in eco-friendly and efficient bioprocessing methods.

Biomass valorization

Green techniques are used to transform renewable materials into advanced products while preserving their inherent structure. Sustainable methods like enzymatic hydrolysis and supercritical fluid extraction maintain the biomass's complex architecture, enabling the development of innovative materials with tailored properties for applications such as biocomposites and bio-based polymers. This approach aligns with circular economy principles, enhancing both environmental sustainability and material functionality. We also implement analytical chemistry methods for the analysis of different biomass resources (plant, algae, fungi and bacterial cell wall).

Fungal Biotechnology

Lab work

We implement the use of cutting-edge integrated fungal biotechnology to ensure the sustainable use of side-streams and recalcitrant residues from biorefinery of lignocellulosic biomass, as an example paper industry. Liquid side-streams from biomass treatments could be used as liquid media to support fungal growth influencing the composition and structure of fungal cell wall. This will provide a future alternative for mycelia cultivation in food, biomedical or material applications. Moreover, a hybrid fungal:lignocellulose network generated by solid-state fermentation, can create composites as renewable and biodegradable materials as alternative to synthetic polyester, for example. Through our engagement in the WWSC we are providing novel alternative for forestry based materials.

Biobased products

Our research group focuses on converting industrial side-streams into bio-based alternatives for diverse applications. We develop sustainable products like algae-based food and cosmetic ingredients, marine collagen for biomedical uses, and biobased foams and films for packaging. By valorizing by-products from various industries, we create high-value materials that promote resource efficiency and sustainability, aligning with circular economy principles. This approach reduces waste and replaces conventional materials with innovative, eco-friendly solutions across food, cosmetics, biomedical, and packaging sectors.

CIRCALGAE project logo


CIRCular valorisation of industrial ALGAE waste streams into high-value products to foster future sustainable blue biorefineries in Europe.

Algae biomass is a treasure in the water, while capturing CO2 vast amounts of biomass are generated. However, this treasure is not being used to the fullest. The EU-funded CIRCALGAE project aims to develop a ground-breaking exploitation system where the algae industrial waste streams will be further valorised, in a more sustainable and circular approach. Through a set of simple, water-based technologies, the project focuses on introducing an integrated biorefinery concept and delivering novel macro- and microalgae ingredients to the food, feed and cosmetic sector. Bringing together a team of key algae cross-sectoral actors, CIRCALGAE aspires to revolutionise the blue bioeconomy and scale up the sustainable use of living aquatic resources.

The project started on October 2022, it will last 4 years and gathers 22 partners from 11 different European countries. Dr. Amparo Jiménez Quero (CHALMERS) is the project coordinator. To know more visit the project website.

SISTERS project logo


CHALMERS is taking part in the EU funded Horizon 2020 project SISTERS. SISTERS aims to reduce food loss and food waste in the main different stages of the Food Value Chain in Europe through innovations targeted to each link of the value chain: new tools to primary producers for promoting direct and Short Chain sales (farmers); new technological innovations in packaging for processors and retailers; and awareness campaigns for retailers and consumers on food loss and food waste.

With the support of the European Commission, SISTERS will be a key EU project addressing the problem in a holistic way, reducing FLW by 27.4% and CO2 emissions by around 20% in the case studies. Our role within the project will be to extract valuable compounds from food lost (with antioxidant, antimicrobial and/or material properties) to be add in the food packaging improving sustainabilty and circularity in the food value chain

The project started on November 2021, it will last 4.5 years and gathers 18 partners from 8 different European countries. To know more visit our SISTERS website.
