Towards Sustainability – from a By-product of the Biodiesel industry to a Valuable Chemical

Sustainable biodiesel and hydrogen energy cycles

One of the main waste by-products of the biodiesel industry, glycerol, can be used as a raw material for the generation of valuable dihydroxyacetone and hydrogen, the latter of which can be used as 100% clean fuel.

Scientists develop a cheap and efficient copper-based catalyst that can be used to convert glycerol, one of the main by-products of the biodiesel industry, into a valuable compound called dihydroxyacetone. In addition, this same process produces hydrogen molecules from water, and these could be used as a clean type of fuel, further highlighting the impact of this research in terms of energy sustainability.

Hydrogen (H2) is a very attractive candidate as a replacement of fossil fuels because it can be produced from water (H...
