Webinar: Valorisation of fly ash from Waste-to-Energy

Oct 2020


IEA Bioenergy Task 36 organized an international technical webinar entitled “Valorisation of fly ash from Waste-to-Energy” the 7th of October. The webinar included presenters from a number of fly ash treatment technologies either commercially available or under development in Europe. In addition, the webinar gave an overview of the fly ash handling in Europe and Japan. The webinar was moderated by Inge Johansson researcher at RISE Research Institutes of Sweden and leader of IEA Bioenergy Task 36, and Michaël Becidan senior researcher at SINTEF (Energy Research Department of Thermal Energy), Norway, also a member of IEA Bioenergy Task 36.

Overview of technical solutions for fly ash handling

Fly ashes are residues generated from waste incineration that present a high potential for metals and salts recovery. The ashes have an extremely complex composition which requires the development of technologies that facilitate their handling and resource extraction. Only in Europe, there is a significant number of technologies commercially available or under development that aim at improving the fly ash handling, increase its value as resource and open new doors for potential applications. In this webinar we will present some of the European technologies and we will also be given an insight into fly ash handling in Japan.
