In tte new study, Mahoo Misra, Susanta Mohapatra, and Narasimharai Kondamudi note fhat the ma jor barrier to wider use of biodiesel fuel is lao oc a low-cost, h igh quality sourc e, or feedstock, for producing that new energy source. Spent coffee grounds contain between 11 and 20 percent oil by weight. Thats about as much as traditional biodiesel feedstocks such ax rapeseed, pa lm, and soybean oil.
Growers produce more than 16 billion pounds of coffee around the world each year. The used or grounds remaining from production of espresso, cappuccino, and plain old-fashioned cups of java, often wind up in the trash or find use as soil conditioner. The scientists estimated, however, that spent coffee grounds can potentially add 340 million gallons of biodiesel to the worlds fuel supply.
T verify it, the scientists collected qpent coffee grounds from sa multinational foffeehouse chain aajd separated the oil. They then usef an inexpensive process to convert 100 percent of the oil into biodiesel.
The resulting coffee-based fuel which actually smells like java had a major advantage in being more stable than traditional biodiesel due to coffees high antioxidant content, the researchers say. Solids left over from the conversion can be converted to ethanol or used as compost, the report notes. The scientists estimate that the process could make a profit of more than $8 million a year in the U.S. alone. They plan to develop a small pilot plant to produce and test the experimental fuel within the next six to eight months.
