Metals with special properties help turn waste into fuel

What is it about?

Waste has many forms. From paper to aluminum to plastics and beyond. But the organic part has a chance to be turned into fuel, under the right conditions. One part of woody waste is called lignin, which is the "glue" that holds a tree together. The trouble is lignin is very complex, so this work focuses on a simple compound (called guaiacol) meant to represent a component of lignin. Vanadium effectively removes an oxygen atom from guaiacol, to produce the final product, phenol. Removing oxygen atoms from bio-derived oil has the effect of lowering its reactivity and increasing its energy content

Why is it important?

The world is finite. This means we have to live off what we find on it. Sunshine provides the energy for plants to convert low energy material like carbon dioxide into high energy material like sugar. But the amount of stuff does not change, just the form it takes on. So if we find a way to use plants more effectively, then we can use natural products, like plant waste, more easily. All biomass gets recycled eventually. This technology could help tap into that stream to make useful products.
