Phosphorous shortage could drive biofuel composition developments

A global shortage of phosphorous could lead to more rapid development of next-generation biofuel composition with heightened yields from less biomass.

Researchers at the University of Wisconsin-Madison warn that a critical point is being reached, as phosphorous reserves around the planet are beginning to approach exhaustion.

Meanwhile, the run-off of fertiliser phosphorous is degrading water quality, promoting unwanted algae growth and damaging freshwater ecosystems, as well as killing fish.

Stephen Carpenter, professor of limnology at the university, says: "Phosphorous stimulates the growth of algae and weeds near shore and some of the algae can contain cyanobacteria, which are toxic."

Next-generation biofuel composition advances could be one way to help reduce the world's reliance on phosphorous as a fertiliser.

Developments in next-generation biofuels are dedicated to removing potentially harmful chemicals from the production process, as well as growing crops which are easier to break down and produce higher yields of energy.
