They used coffee grounds to grow microalgae and make fuel.
Researchers at Aston University have created low-emission biodiesel from leftover coffee grounds. It was written by The Fish Site.
Here, scientists grow algae, which is then processed into fuel. As a result, they have developed an advanced biodiesel fuel that delivers low emissions and excellent engine performance, while also meeting US and European regulations.
Until now, algae have grown on materials such as polyurethane foam and nylon, which lack any nutrients. However, researchers have discovered that microalgae cells can grow in coffee residue without the need for other external nutrients.
In addition, keeping the algae in the light for 20 hours a day and in the dark for only four hours a day, you can get the highest quality biodiesel.
“This is a breakthrough in the microalgae culture system. Biodiesel from microalgae attached to spent coffee grounds could be an ideal choice for the commercialization of new feedstock, avoiding competition from food crops. The use of coffee as a new feedstock can reduce the need to cut down palm trees for oil for biofuel production. In addition, the use of this new feedstock can reduce the deforestation of palm trees for biofuel oil, which has resulted in continued deforestation and increased greenhouse gas emissions in Southeast Asia.
Recall that early Australian scientists discovered that coffee drinkers have a reduced risk of age-related cognitive impairment, which is associated with a slower accumulation of amyloid proteins in the brain.
