Clean Tech Block from Denmark

logo_smallClean Tech Block is a project from  Gråsten Teglværk, the University of Aalborg and the University of Ljubljana. A few posts were already written about Aalborg and in fact, they collaborate with Ljubljana. I had the occasion to met very interesting people: Y. Yue and Martin B. Østergaard in Aalborg and Jakob König in Ljubljana.

This team did what I believed for a long time was impossible. They managed to foam directly waste glass (without melting) with closed cells, filled with CO2 with a minor content of H2. In my opinion, this is the best progress in cellular glass land in the last five years. In this way, cellular glass with 0.040 W/mK and 600 kPa compressive strength based on waste glass without remelting becomes possible at prices of about 150€/m³. They want to use this cellular glass between bricks to able to build houses like explained here under. It is a Google translation from Danish to English.
