Abstract
The development and use of sustainable technologies for acquiring new and innovative products enable industry to exist and be competitive in this very demanding world market. High-pressure technologies that were initially developed in Europe represent the new process tool for the 21st Century industry. High-pressure technologies and processes with the use of supercritical fluids (SCF) enable sustainable development and represent high potential of use for various purposes. The leading research team in the SCF field in Slovenia is the Laboratory for separation processes and product design at the Faculty of Chemistry and Chemical Engineering at the University of Maribor (FKKT). In this area of work the laboratory has been internationally renowned since 1985 and is currently equipped with appropriate and necessary equipment for development and application of high-pressure processes with SCF. As an applicant of the research project the laboratory in setting new goals within this scope, that is to develop: - new sustainable technologies for polymer processing, - new tailor made polymer products with high added value.   Polymers can be found everywhere in our daily life; most of the products are entirely or at least partially made of polymers. Due to their variety of mechanical characteristics (fragile, solid, elastic, rubbery, etc.) they can be used for many purposes. Within this project we will use sustainable technology with SFC to develop polymers for applications in: -       paint and varnish industry (polymer micro beads, microcapsules, composites) -       medicine (active substance carriers, porous structures and tissue engineering membranes) -       isolation material industry (polymer foam)   With an appropriate selection of foreign partners (Institute for process technology and transport processes at University of Bochum -VTP and Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT in Oberhausen), leading in the Federal Republic of Germany in the development and planning of high-pressure micronization processes, we assure the critical mass and know-how for successful development of sustainable technologies and processes for acquiring new polymer products. Foreign partners will enable transfer of the processes into the semi-industrial and industrial scale, with a local business partner Helios d.d. actively participating.   The project results will contribute to: -       planning a plant for producing new high added value products to increase the competitiveness of the local business partner (Helios d.d.) and to contribute to the realization of their vision to rank at the top ten of the leading paint and varnish producers in Europe. Potentially introduce new production program in Helios d.d. -       the acquisition of new knowledge in the field of polymer processing for medical purposes, which will bring to the active cooperation with the University Clinical Center Maribor (UKC-) and the Faculty of Medicine at the University of Maribor (MF).   The results of the performed research in the field of polymers will contribute to better connectivity and cooperation of Slovene and foreign institutions within the preferential area of research and technological development: complex systems and innovative technologies.
Significance for science
SCF show high potential as environmentally friendly solvents for various applications. They have already proved their efficiency at industrial scale for extraction of valuable components from natural materials. However in other fields, such as biomaterials processing, foam or microparticles formation, research is still necessary to obtain the data needed to optimize and design the technologies. This project will represent a step forward in understanding the interactions between SCF and various substrates and in using and managing these interactions in order to obtain products with desired properties. The main aim was achieved that is to obtain fundamental data regarding the phase behavior of different substances (polymer, composites or active compounds used for their impregnation) in the presence of SCF. These data are vital in process design, and all results will be published in the hope of contributing to the development of the field SCF applications in various scientific and industrial fields. The use of unique characteristics of SCF (transportation characteristics, melting force, etc.) could increase the industrial competitiveness of Slovenia and at the same time create environmental and economic benefits for Slovenia and also for the EU. The technologies developed with the help of SFC have globally proven as one of the most important sustainable technologies with almost zero impact to the environment. Various operating fields that were joined in the project and collaboration of partners from the fields of science and economy enabled/and will enable: - development of new high added value products with the help SCF, which are impossible to produce with conventional processes, - development of new technologies in the field of SCF for sustainable economic development of Slovenia, - production of products in forms and with specific tailor made properties, - tests in the pilot scale, transfer of technologies into the industry, etc. The research results contributed/ and will contribute to fundamental knowledge in the following fields: - binary and ternary phase equilibria in imperfect systems with SCF, - mass transfer in systems with supercritical fluids, - high pressure micronization processes – PGSS.
Significance for the country
The project aims were to design and optimize of products which can find a large number of applications, with significant economical and social advantages. In the field of coatings, now higher qualities of films may be obtained due to a better control of particle size and particle size distribution. Although the production costs involve specific equipment, some of the processing steps, such as solvent removal and product drying, will not be any longer necessary, therefore no significant increase in product price is expected. Thus better quality at similar price is one of the desired results. The project results partially contributed to planning a plant for producing new high added value products to increase the competitiveness of the local business partner and cofinancer Helios d.d. In the field of medical applications, modern medicine proves more concern for the patient’s comfort and compliance. Therefore extensive research is employed for improving effectiveness of drug carriers and of tissue engineering scaffolds. SCF may offer the possibility of optimizing such devices, leading to a better response of the organism to implants, a smaller risk of immune rejection or inflammation, in other words to faster healing without undesirable side effects. Development of new, cleaner procedures for production of special chemical products is one of the basic challenges of chemists and chemical engineers not only in Slovenia but globally, for without cleaner procedures our lives and development would not be sustainable. It is of great importance that EU and Slovenia play a leading role in such development if we want the chemical industry to benefit from those results. The research within this project offered new technologies with small impact to the environment and local knowledge for high added value products, marketed in Slovenia and worldwide. The use of unique characteristics of SCF (transportation characteristics, melting force, etc.) that could increase the industrial competitiveness of Slovenia and at the same time create environmental and economic benefits for Slovenia and also for the EU. With new high quality and competitive products and technologies we will increase the production program and extent, and create a possibility also to open new job positions.
