 The benefits of coffee grounds: scientists have found a new method for extracting biofuels < /p>

Researchers at Aston University have created low-emission biodiesel using leftover coffee grounds.

Reported by The Fish Site.

In experiments, scientists used coffee grounds to grow algae, which were then used to produce biofuels.

So far, algae have been grown on materials such as polyurethane foam and nylon, which do not contain any nutrients .However, researchers have found that microalgae cells can grow on coffee residue without needing other external nutrients.

“Biodiesel made from microalgae attached to spent coffee grounds could be an ideal choice for commercializing new feedstocks while avoiding competition from food crops,” the researchers said in a statement.
