If turning used coffee grounds into biofuel sounds like a complex process, that’s because it is. The process is energy-intensive and time-consuming, which is why its widespread use is unlikely. That could soon change, however, as scientists from Britain’s Lancaster University have simplified the coffee-grounds-to-biofuel conversion process. Whereas the original conversion process had an oil extraction step and an oil-to-biodiesel step, the new conversion process combines the two steps, reducing the time it takes from two hours to just 10 minutes. The simplified process could make used coffee grounds an economically viable source for producing biofuel, meaning less of it ends up in landfills.
