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 —>
There has been a long debate about why dinosaurs were so successful. Say dinosaur, and most people think of the great flesh-eaters such as Tyrannosaurus rex, but the most successful dinosaurs were of course the plant-eaters.
A new study from the University of Bristol, led by Masters of Palaeobiology student Eddy Strickson, has presented clear evidence about how plant-eating dinosaurs evolved.
In the rich dinosaur deposits of North America, hundreds of skeletons of plant-eaters are found for every T. rex. But how did they survive and proliferate? Was it down to innovation or stimulus by plant evolution?
Eddy Strickson said: “The plant-eating ornithopods showed four evolutionary bursts; one in the middle of the Jurassic, and the other three in a cluster around 80 million years ago in the Late Cretaceous. This was down to innovation in their jaws and improved efficiency.”
Plants were evolving fast during the Mesozoic, with the rise of cycads, conifers, and Read on —>
