The aim of the COMBIVET project is to establish an ERA Chair of Comparative Medicine under the Institute of Veterinary Medicine and Animal Sciences (IVMAS) at the Estonian University of Life Sciences. Comparative medicine has great untapped research potential as many of the health challenges faced by humans and animals are the same. This includes age-related diseases, cancer, neurodegenerative diseases, cardiovascular diseases, bone and joint diseases (e.g. osteoarthritis and osteoporosis) and metabolic diseases (e.g. diabetes and insulin resistance). Thanks to these similarities, knowledge gained from studying and treating animal patients can be applied in humans while developing new diagnostic tools, vaccines and therapies for both humans and animals. As such, IVMAS seeks to establish the ERA Chair of Comparative Medicine in order to develop its competences and capacities in the research field and ultimately become one of the leading European research organizations in comparative medicine. As the first step, the COMBIVET project will focus on e.g. creating the new ERA Chair as a physical unit at IVMAS, recruiting an outstanding Chair holder and research team with complementary skillsets, improving the ERA team’s comparative medicine skills and knowledge, developing databases and animal models based on collected samples and carrying out various activities designed to increase the sustainability of the ERA Chair beyond the project lifetime (including making presentations, preparing publications, organizing seminars, industry and public sector meetings, submitting research proposals and popularizing comparative medicine in society).

Advanced food processing technologies, minimum waste and maximum utilisation of raw material used as well as valorisation of by-products constitute a highly relevant range of topics in the EU and worldwide. These are matters that the University of Life Sciences (Eesti Maaülikool, EMU) has been dealing with for long from various angles and perspectives. However, to realise the full potential of EMU in this domain, structural changes are needed to bring various related competences under a unified umbrella as well as to cover several gaps hindering further development. Therefore, the main objective of the current project is to establish a new ERA Chair for Food (By-) Products Valorisation Technologies (VALORTECH), and recruit a top level researcher/research manager (ERA Chair holder) to lead this interdisciplinary, inter-unit entity, formed based on a joint effort by the Institute of Agricultural and Environmental Sciences and the Institute of Veterinary Medicine and Animal Sciences of EMU. The new Chair is expected to considerably improve the research and innovation performance of EMU and conduct forefront research that would create significant benefits for both Estonia, Europe and beyond. Efficient dissemination and exploitation of research results is an issue of key importance in the context of the ERA Chair´s action plan. In addition to targeting the international research community and providing input to policy development, facilitating knowledge transfer to industry is at particular focus. The R&D to be carried out in the VALORTECH Chair is strongly connected with both the national and regional Smart Specialisation strategy, in the context of which efficient use of resources and related development of health-promoting (functional) food are among key priorities. The demand for advanced R&D services in the VALORTECH fields from the side of the industry currently exceeds the capacity of EMU to provide such services.

Pulp and paper industries (PPI) are known for producing large quantities of organic residues. Considering the economic and environmental aspects, the resource recovery from PPI wastes is necessary in order to increase the resource efficiency. In that regard, developing novel biorefinery processes to produce multiple products from PPI wastes is interesting under bio and circular economy. On the other hand, the interest on torrefied biomass is rising over the globe as it can replace the coal. However, the economics of torrefied pellets is not competitive compared to the coal. As the majority of the torrefied pellets production costs are coming from raw materials, sourcing them from low cost resources could be helpful to improve the economic competitiveness of the torrefied pellets over coal. To address the above said two issues, this project will study the feasibility of the torrefaction of pulp and paper industry sludge (PPIS) and integrating it with microbial conversion to produce bioenergy carriers i.e. bio-coal and bio-methane and volatile fatty acids. To achieve this, the expertise of the experienced researcher on biomass torrefaction, process modeling and feasibility analysis will be combined with the expertise of the supervisor on microbial conversion processes and biomass pretreatment. Initially, torrefaction of dewatered PPIS will be carried out in order to establish the biofuel characteristics of torrefied PPIS. Later, anaerobic digestion of torrefaction condensate produced through the torrefaction of PPIS will be studied at varied operating conditions in order to establish the production potential of bio-methane and volatile fatty acids. Finally, the proposed process integration will be simulated to a commercial scale from laboratory experimental results in order to evaluate the techno-economic and environmental feasibility. The proposed study can help the European society to shift toward low carbon economy and achieve sustainable development goals.
