insulation

  • Where do old clothes go when they finally give up the ghost?

    Ripped jeans may be ‘in’ but even the most hard core follower of fashion has to give up at some point eventually. Add those jeans to the mountains of other garments Europeans throw away every year and you are looking at a lot of raw material just waiting to be recycled.

  • Fly ash, the light-weight ash produced by coal combustion in the blast furnaces of thermal plants, most often ends up as landfill. The EU produces two million tons of it every year.

    An EU-backed project, GREEN CAST, has found a way of using fly ash to make a building material that provides excellent insulation and is cheaper and more sustainable than the traditional cement-based cellular concrete.
