The future doesn’t just belong to ecomaterial. Glass is the shining example.
Initially, i.e. many centuries ago, glass was not very transparent or resistant. Scientific progress allowed glass to gain in transparency and strength. That is why the manufacturing of glass requires a great deal of energy because the transformation temperature is high. It emits CO2, heavy metals and polluting gases in industrial quantities.
Glass is far behind wood, stone, earth or straw in terms of ecological materials. However, it is far ahead of the pet peeves of ecologists: PVC, aluminium and even steel.[……]
