UK: Renewable gas from human sewage

A sewage works in Oxfordshire, England is providing natural gas from human waste to the power grid.
As much as 15% of natural gas in the UK could come from biogas or biomethane by the year 2020, according to the National Grid.
Since biomethane is both a renewable power source and a way to use waste, it is seen by many as a win-win innovation in energy solutions.
The average person produces the equivalent of 30kg of dried-out sewage sludge a year that could be used for producing gas. In theory that means the UK’s 62.5 million people could generate enough renewable gas to meet the annual demand of 200,000 homes, up to 1% of the population.
–Herald Scotland
That may not sound like so much, but gas can also come from brewery waste, food waste and agricultural slurry.

Greener Cities and the Drivers Who Call Them Home
Urban Forestry is a growing trend in cities looking to actively clean their air and water while making streets aesthetically pleasing for pedestrians, bike riders, and drivers as well. While I could list any number of benefits trees in urban areas have been shown to produce, there was one advantage that I didn’t expect to see: safer, more eco friendly carsdriving through cities. Now, you might be wondering how trees help to slow drivers down and create an atmosphere where greener...
Denmark’s Eco-Architecture Now Going to the Arts
The Danes are going through a green building frenzy as of late and it doesn’t look like they’ll be slowing down or stopping any time soon. Yet another eco-architecture project is being planned for Denmark’s second largest city, Aarhus. Designed by 3xn and Nord Architects, a new cultural center shall make way for those interested in visual arts, literature and scenography—the practice of making things like theatre sets and costumes. In particular, the Northern Goods Railway center will serve to inspire...
Q: Are circuses cruel to animals?
I don’t get animal rights activists’ crusade against circuses. The animals are fed well and their lives are in less danger in comparison to their natural environments. They look happy while performig. An hour spent in a circus is also a rare occasion to look at wild animals. Why do some people want to ban them? A: For several reasons. Wild animals are wild, which means they should be born, live and die in the wild. Those that are used for entertainment...
Stockholm heats office building with excess warmth from busy train station
The central station in Stockholm, Sweden is Scandinavia's busiest travel hub, serving 250,000 travelers every day. These hurried commuters generate a lot of body heat – and Swedish engineers have come up with a way to transfer this heat to a neighboring office building. It's a cheap, renewable and innovative solution for the building's energy needs. An article in Time magazine's Going Green section explains: Using excess body heat to warm a building is not a new concept — the Mall of...
TCM quackery fuels brutal rhino poaching
So far this year poachers have killed 265 rhinos in South Africa, quickly approaching last year’s record 333 killings. To put this number in perspective, only 13 rhinos were poached in 2007. The cause for this carnage is the skyrocketing trade in rhino horn, due to the false belief that it cures cancer, headaches and fever. This unscientific notion is widespread in China, as well as in some communities in South East Asia, where increased affluence is fueling the illegal rhino...
Have you ever seen flying rhinos?
Flying Rhinos: WWF's Black Rhino Range Expansion Project Last week, Green Renaissance filmed the translocation of the seventh black rhino population established by the WWF Black Rhino Range Expansion Project, after an epic 1500 kilometre trip across the country. In this translocation, 19 of the critically endangered animals were moved from the Eastern Cape to a new location in the Limpopo province. “This was possible because of the far-sightedness of the Eastern Cape Provincial government who were prepared to become partners in...
Chimpanzees Show No Fear When Dealing With Wildfires
Chimpanzees are recognized as close primate cousins of humans. Recent findings—published in the American Journal of Physical Anthropology—show that these loveable primates may have developed another human-like trait: the ability to predict wildfire movement and how to react accordingly. Jill Pruetz, a primatologist of Iowa State University, believes this development may help scientists gain better understanding of our primitive ancestors and how or when they first learned to control fire. Puertz was spending time in Senegal in 2006, observing savanna chimpanzees...
European protests are also Green (and good)
A couple of days ago I posted about why the Occupy Wall Street action is Green, quoting various articles by luminaries of both the environmentalist and anti-globalization movements. Besides specific environmental issues being addressed at OWS and other similar protests around the world, the logic is plain: economic and political models based on unrestrained growth, consumerism and unregulated finance and industry are not only unfair and undemocratic, but clearly ecologically disastrous. From dirty tar sands in the North, to dams and deforestation...
Green Eggs and… Childcare Development
Have you ever heard the phrase “get them while they’re young”? Well, apparently that also applies to the green lifestyle. German designers GPAC have designed the Discovery Childcare Center: a preschool in the shape of 13 eggs. These egg structures can be moved and positioned in a number of ways. They are also connected by a common area, dubbed the “Discovery Zone”. In this zone will be a number of activities—such as arts & crafts, exercise, and theater performances—that will aid...
Debate continues to rage in Spain after Catalonia’s bullfighting ban
The Catalan parliament recently voted to ban bullfighting, a decision scheduled to go into effect in 2012. At the first bullfighting event in Barcelona since the ban, the industry and its supporters were out in full force to protest the ban and assert their ‘right’ to tease, abuse and stab young bulls to death for the amusement of the crowd. A manifesto by the group La Mesa del Toro was to be read out at all bullfighting events in Spain, France...
