The ETH spin-off FenX has developed a process to produce insulation material from industrial waste. "This is not only easy, but is also produced sustainably and is not flammable," says the article from ETH Zurich.
The industrial waste is mixed with water and some additives. The result is a porous foam, which later solidifies to the insulating "meringue".
The production is energy-saving, because unlike artificial alternatives, no great heat is necessary for the foam to solidify. "On the other hand, the whole process is based on recycling - the insulating panels installed in walls or roofs are reusable," say the inventors of the new material.
You are still in the test phase. ETH Zurich reports: "The four materials scientists are still investigating which industrial waste can be processed as an insulating foam. For first tests they used fly ash. But other waste, such as from the construction, metal or paper industry, should be processed. "
