Waste-based + CO2 activated prototypes presented at Coimbra (Portugal)

“Sustainable building materials and solutions” is the topic of the Public Exhibition promoted by IteCons and CCDRC Centro, ongoing at Alma Shopping – Coimbra, between 14th to 24th February.

The GEOGREEN patented system (modular system for vegetated surfaces) and 3 perforated prototype blocks (cobogós) based on industrial and household residues; namely mining, ceramic and glass waste were exhibit. One of the “cobogós” was obtained by expansion inside mould and the other one was obtained by CO2 activation of electric-arc furnace slag (showing high mechanical strength, more than 100 MPa). In addition to the reuse of industrial and household waste and as well on CO2 capture, all prototypes were produced practically without using water. 

The exhibition is taking place simultaneously with the 3rd Luso-Brazilian Congress of Sustainable Construction Materials (CLBCMS 2018).
