Circular economy and low-impact materials production are the desired targets of the future. In the field of
building materials, Portland cement based mortars are being questioned because of their high CO2 footprint.
Geopolymers matrix may offer an alternative to the traditional binders, particularly when deriving from industrial
wastes. In the present study, the possibility to formulate alkali activated blends made of metakaolin and up to a 50
% wt, bottom ashes deriving from urban waste incinerations is investigated. Moreover, to increase the mechanical
properties in particular to reduce brittleness and increase flexural strength and increase the dimensional stability of
mortars scraps deriving from the production of epoxy-carbon fiber have been recycled in the same materials without
any chemical or high temperature treatments. Positive results have been obtained thus supporting this recycling

Andrea Saccani is Associate professor at the University of Bologna. His main interests are composite materials formulated either with organic or inorganic polymers. He has studied the possibility to recycle different types of urban and industrial wastes, investigating the effects on mechanical properties and durability. He has published 70 papers on international peer-reviewed journals (Scopus).
