Australia has one of the highest incidences of pet ownership in the world with latest data showing that 63% of the 7.5 million households own a pet. As the dog population in Australia continues to grow, so will the issue of dog 'waste' disposal in a waste management system of increasing urbanisation, a limited amount of suitable park spaces and shrinking landfill sites. On average, a dog produces 0.34 kilograms (kg) of feces per day. Consequently, there is approximately 1,400 tonnes (t) of dog waste to be disposed of every day in Australia; 490,000 tonnes (t) per year. Therefore we want to build an anaerobic methane digester to process the dog waste (and other appropriate wastes) to create a biogas that can serve as renewable energy source to super-power your dog parks. 

"THE smelly scourge of suburban parks and footpaths could soon, literally, be seen in a whole new light. The contraption, called the Park Spark, was devised by a Massachusetts Institute of Technology graduate. Park Spark users put their dogs' waste in biodegradable bags and then into tanks, where a wheel turns to break it down and release methane, which powers a gaslight-style street lantern."

IT'S a problem that besets every urban area: dodging dog droppings on the footpath. Now one town has come up with a clever way to keep doggie doo off its streets - and remind owners of their responsibilities. It sends the offending deposits back to the owners marked "Lost Property".

The Dog Rocks Flora and Fauna Sanctuary, near Geelong, was established when the current owner George Belcher's great grandfather purchased the property in 1856. The Belcher Family has preserved the Sanctuary as valuable and beautiful natural bush land for over a century, and it has become an important area of conservation for our rapidly disappearing flora and fauna.

"For the first time ever, environmental groups have staged a mass walkout of a U.N. climate summit. Citing immense frustration with the lack of productive action in the COP19 climate talks, which have been dogged by a persistent rift between rich and poor countries on the responsibility of paying for climate damages, hundreds of people from dozens of environmental groups and movements from all corners of the Earth have voluntarily withdrawn from the talks. According to a spokesperson for Oxfam, around 800 civil society members (which is the label applied to all advocate and activist types at these meetings) have walked out. In a joint statement, group leaders offered that "the best use of their time" was to now focus "on mobilizing people to push our governments to take leadership for serious climate action.""

"Abbott's latest remarks on carbon pricing betray the fact that his views on climate change are inspired from the depths of the climate denier blogosphere"

"Researchers at Stanford University have found a way to harvest considerable amounts of electricity from an unlikely source: poop. In a paper published this month in the Proceedings of the National Academy of Sciences, Xing Xie and his team of engineers describe a "microbial battery" capable of generating electricity from naturally occurring sewage bacteria."
