This Centre of Excellence (CoE) focuses on fostering innovation in resource efficiency, promoting circular economy practices, utilizing local resources, ensuring safe material circulation, and educating researchers to reduce environmental impacts. It centers around four key areas: Strategic Mineral Resources (SMR), Carbon-Based Resources (CBR), Circular Technologies Upscaling (CTU), and Circular Business Eco-System and Modeling (CBEM). The SMR group maps critical materials in waste streams, including renewables, for extraction and reuse while minimizing hazardous waste. The CBR group develops eco-friendly pathways for essential chemicals and plastics, also assessing their environmental impact. The CTU group pioneers waste reduction and recycling methods for aqueous, and solid waste, incl. water purification. The CBEM group analyzes sustainable business ecosystems and value chains. This CoE's interdisciplinary approach will benefit both Estonia and Europe by advancing circular economy.
The efficient utilisation of bio-based resources is essential for achieving a sustainable, carbon-neutral society. AGRI-WASTE2H2 will focus on straw-derived cellulose – an abundant but underexploited agricultural side-product – as feedstock in an advanced electrochemical process, tailored for enhanced efficiency in the production of green hydrogen with significantly reduced energy consumption compared to standard water electrolysis. At the same time, the process will concurrently produce valuable platform chemicals and materials.
AGRI-WASTE2H2 relies on the combined expertise of researchers in three Nordic-Baltic countries – Finland, Sweden and Estonia. The Synthetic Flow Chemistry group at Tallinn University of Technology, Estonia, will focus on transferring the electrochemical oxidation of cellulose into the flow regime, aiming to achieve high efficiency and productivity of the developed transformation. The scaling-up process in flow is a key step for a successful industrial application.
AGRI-WASTE2H2 capitalises on the abundance of renewable electricity and agricultural side-streams in the Nordic-Baltic area to produce fuel and chemicals, thereby alleviating the region’s dependence on import of fossil feedstocks. As such, the project will result in tools for reduced CO2 emissions and increased regional resilience, while spurring the growth of new green industries of particular benefit for rural areas. The collaboration between researchers three Nordic-Baltic countries will enable results beyond what the individual partner can achieve alone and promote regional mobility and new collaborations. By leveraging our specialised know-how, we aim to drive innovation tailored to our regional needs and strengths.
Asymmetric catalysis plays one of the most important roles in the modern organic chemistry providing methods for the synthesis biologically active compounds and pharmaceuticals. Merging well-developed organocatalysis with electrochemistry opens new horizons for asymmetric transformation beyond the classical thermochemical activation. This approach is sustainable, since it employs harmless organocatalysts to induce chirality and electrons as traceless and green reagents to generate highly reactive radical species under mild reaction conditions avoiding the utilization of highly toxic and expensive RedOx chemicals. The efficiency and reliability of such transformations can be enhanced by performing the reaction in continuous-flow mode. The project is an example of cutting-edge science combining different research areas of organic synthesis and chemical engineering that can be potentially applied for discovery of new and potent life-saving drugs.
