Turning old coffee waste into cleaner biofuels – Science Daily News


Future Americano, cappuccino and latte drinkers could help produce the raw material for a greener biofuel that would reduce our reliance on diesel from fossil fuels.

Purpose-grown feedstocks (used to extract oils) for biodiesels are controversial because of their cost and the demand they place on land and water. However, spent coffee grounds, which have a high calorific value, offer a good low-cost alternative feedstock. However, most used coffee grounds are currently just dumped. In 2014 more than nine million tonnes of spent coffee grounds were sent to landfill.

Although a small number of businesses are using spent coffee grounds to make biofuels, researchers at Lancaster University have found a way to significantly improve the efficiency of the process- vastly increasing biofuel from coffee’s commercial competitiveness.

The chemical engineers have consolidated the existing multi-stage process into one step (known as in-situ transesterification), please read on —>
