摘要

Power generation industry has tackled waste reuse and valorisation for decades. Nevertheless, new technologies, like Circulating fluidized bed (CFB) boilers operating in oxy-combustion, have an important gap of knowledge in residues characterization and valorisation. This project will tackle this. Furthermore, as a result of the high quantity of waste that these installations generate new business models can be opened. The project aims at characterizing the residues from a large scale oxy-CFB facility with carbon, capture, use and storage (CCUS) focusing on the larger and main residues produced: fly ash, bottom ash, and algae production from captured CO2. An analysis of possible uses and treatment needs, such as additives or preparation for use in agriculture or industry, will be carried out. Best re-utilization and valorisation options will be stated for fly ash, bottom ash and algae, aiming for a novel combination of CO2 capture technologies with recovery of valuable materials from different wastes, addressing different and sustainable solutions for their reuse, enhancing the feasibility of CCUS, and combining research with the creation of new business models towards a green economy more attractive to the public perception.
