Cow power could generate electricity for millions
Converting livestock manure into a domestic renewable fuel source could generate enough electricity to meet up to three per cent of North America's entire consumption needs and lead to a significant reduction in greenhouse gas emissions (GHGs), according to US research published today. view more (2008-07-24)
Energy efficient sewage plants
High-rate digestion with microfiltration is state-of-the-art in large sewage plants. It effectively removes accumulated sludge and produces biogas to generate energy. A study now reveals that even small plants can benefit from this process. view more (2009-08-14)
Virtually engineering power plants
Photovoltaic and wind energy plants, hydroelectric power stations and biogas plants supply energy without polluting the environment. However, they are complex to design and maintain. Virtual reality (VR) makes planning and operation easier. view more (2009-07-14)
Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. view more (2007-12-11)
BSE Residues: anaerobic digestion saves 45 million euros a year
The treatment of BSE residues through anaerobic digestion is, according to Quercus, the most efficient and fruitful way of resolving this environmental question. This is a biological process successfully put into practice in a national company, ITS Marques, and consists of the degradation of organic matter by microorganisms in the absence of... view more...

More biogas, less sludge
Germany has more than 10,000 sewage plants, using costly processes to treat household, industrial and restaurant waste water. The treated water is discharged back into river and lake systems. What remains is an organic / inorganic mixture of sludge. The issue is how to dispose of this residue. Up to now, sewage sludge has been used as an... view more... (2002-11-14)
Key issues for the future of wind energy

Microscopic manufacturers produce eco-friendly plastics
Last year's energy crisis highlighted an unforseen by-product of the looming fuel shortages of the 21st century. Petroleum-based products such as plastics that society takes for granted but now requires to function will run out with the oil. view more (2009-05-19)
Biogas production is all in the mixing
Engineers at Washington University in St. Louis, using an impressive array of imaging and tracking technologies, have determined the importance of mixing in anaerobic digesters for bioenergy production and animal and farm waste treatment. view more (2008-04-17)
