Rapeseed-based animal feed cuts greenhouse gases by up to 13 per cent

The use of rapeseed cake in the production of livestock feed cuts methane and carbon dioxide emissions by up to 13%, according to the initial results of the research carried out by Neiker-Tecnalia within the framework of the Life-Seed Capital project.

Now it will become cheaper to make second-generation biofuel for our cars

Producing second-generation biofuel from dead plant tissue is environmentally friendly -- but it is also expensive because the process, as used today, needs expensive enzymes, and large companies dominate this market. Now a Danish/Iraqi collaboration presents a new technique that avoids the expensive enzymes. The production of second generation biofuels thus becomes cheaper, probably attracting many more producers and competition, and this may finally bring the price down.

Pond-dwelling powerhouse's genome points to its biofuel potential

Duckweed is a tiny floating plant that's been known to drive people daffy. It's one of the smallest and fastest-growing flowering plants that often becomes a hard-to-control weed in ponds and small lakes. But it's also been exploited to clean contaminated water and as a source to produce pharmaceuticals. Now, the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant's potential as a biofuel source a big boost.

Study on methane emissions from natural gas systems indicates new priorities

A new study says that the total impact of switching to natural gas depends heavily on leakage of methane (CH4) during the natural gas life cycle, and suggests that more can be done to reduce methane emissions and to improve measurement tools which help inform policy choices.

Solar-induced hybrid fuel cell produces electricity directly from biomass

Researchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy. The hybrid fuel cell can use a wide variety of biomass sources, including starch, cellulose, lignin - and even switchgrass, powdered wood, algae and waste from poultry processing.

Archaeologists lend long-term perspective to food security and climate shock

What role does pre-existing vulnerabilities play for people who experience a climate shock? Does it amplify the effects of the climate shock or is effect negligible? Four Arizona State University archaeologists are looking into this as part of an international team examining how people can be most resilient to climate change when it comes to food security.

Waste from age-old paper industry becomes new source of solid fuel

In today's search for renewable energy sources, researchers are turning to the hi-tech, from solar and hydrogen fuel cells, and the very low-tech. The latest example of a low-tech alternative comes from an age-old industry: paper. A new study reveals a sustainable way to turn the huge amounts of waste from paper production into solid fuel with the added bonus of diverting the sludge from overflowing landfills.

Is global warming hiding under water?

Satellite observations of global sea-surface temperature show that a 30-year upward trend has slowed down within the last 15 years. Climate scientists say this is not the end of global warming, but the result of a rearrangement in the energy flow of the climate system and, in particular, how the ocean stores heat.
