Green Technology Group´s mission is to contribute to a sustainable development through research in chemistry. The first main research direction is the development of environmentally sustainable extraction, biocatalysis and separation processes to upgrade biomass waste to high-value products. Target biomass samples are forestry, agricultural and fishery byproducts and wastes, and molecules of interest are for instance polyphenols, lipids and sugars. The second research direction is the production of nano/micro particles and surfaces using supercritical carbon dioxide as a solvent. Applications are found in drug, food and cosmetics, as well as in packaging, textiles and building materials. Central for Green Technology Group´s research is the use of supercritical carbon dioxide and pressurized hot water as processing media. These solvents have minor environmental impact, and they enable fast and efficient processes.
