Sunn hemp shows promise as biofuel source

Work by scientists at the U.S. Department of Agriculture (USDA) suggests that farmers in the Southeast could use the tropical legume sunn hemp (Crotalaria juncea) in their crop rotations by harvesting the fast-growing annual ...

Solving the bottleneck in biogas production

Agro-biogas plants produce renewable energy, extracting gas produced in the anaerobic fermentation of animal manures mixed with organic wastes from the food sector. One by-product of this fermentation process is a thick liquid ...

Compact and flexible thermal storage

Biogas plants, combined heat and power plants don't just generate electricity, they also produce heat. However, unlike the electricity they yield, the heat generally dissipates unused. A new technology is set to change this: ...

More energy from a liter of biofuel

Oil produced from biomass - such as wood chips or plant residues - seldom has the same quality and energy content as 'classical' crude oil. A new, simple catalyst, developed at the University of Twente, improves the quality ...

Citizen science: knowing your food's carbon footprint

Sustainable food consumption is considered critical for combatting climate change. Sustainable food choices are thought to be key to reducing the environmental impact of human food consumption, with the food lifecycle contributing ...

Asian black bears' smart strategy for seasonal energy balance

A collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT), Japan, has discovered that daily energy balance of Asian black bears (Ursus thibetanus) exhibited seasonal change with a twin-peak ...
