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 project is aimed at changing the current paradigm of using oil shale by direct transformation of its valuable structural components into high-value chemicals, with the goal of developing an environmentally friendly chemical industry. The focus is set on expanding advanced methods for obtaining base chemicals through the chemical transformation of kerogens from various sources, as well as developing environmentally friendly holistic solutions. These efforts aim to enhance the efficiency of using other geological resources and allow for the utilization of already generated waste. The objective is to develop innovative uses for raw materials that create added value, find applications for residual oil shale in waste rock piles, and align with green transition strategies. The focus is on Estonian mineral resources, but the project also envisions the utilization of other difficult-to-transform organic materials for obtaining chemicals.

The project deals with the development of sustainable methods of asymmetric catalysis and their application in the synthesis of biologically relevant compounds. Various methods of catalysis (organo-, metal- and enzymatic catalysis) will be used separately or in cooperative manner. Special attention will be turned to the increase of efficiency of reactions by using selective catalysts, cascade or one-pot reactions. As a new method, a halogen bond donor catalyzed asymmetric reactions will be studied. New reactions will be applied on the synthesis of biologically active compounds and their derivatives. As a result, new asymmetric catalytic sustainable methods for the creating molecular complexity will be developed. Principles of green chemistry will take root in science, in the mode of thinking of PhD students and by PhD graduates in Estonian chemistry enterprises.
