    Asphalt for pavement and shingles is amaong the most recycled materials on the planet.

    Not how you think. The asphalt is ground up for the mineral content then mixed with new bitumen.

    Soap and shampoo can be made from animal fat or vegetable oil.

    Most of it is. Cheapest way to do it.

    Hydrogen can be made from water. You get oxygen too.

    By wasting a lot of electricity.

      Just curious, how is the majority of hydrogen produced/mined/farmed now?

      I kinda always assumed it was electrolysis just because the process is so simple.

        Most hydrogen is currently produced from methane, meaning natural gas. It’s a huge source of carbon dioxide.
