G'day All,

The message below is sent on behalf of Jurg Keller - I will fix his address so he can post directly.

If you change your e-mail address you can remove your old address (if you will not be using it - if you want two addresses and only one copy you can set one address to "nomail") and resubscribe (I will still have to approve it).

Happy Digesting,
HOOROO

This is an interesting discussion on the power generation capacity at AUS wastewater treatment plants. I am constantly watching what is being achieved in different parts of the country but so far I'm only aware of one (secondary treatment) plant that is actually achieving complete energy self-sustainability, which is Melbourne's WTP (Werribee). This case is somewhat different from most plants though in that they have up-front large anaerobic ponds with covers to capture the methane, then followed by an activated sludge plant.

Do any others (maybe the new Bolivar?) actually get to generate enough energy to power the whole plant? I know some in Europe achieve this (without the anaerobic ponds), but not sure any in AUS are close or there yet except Melbourne (and some primary tmt plants in Sydney). Any suggestions welcome.

G'day All,

Bolivar Sewerage Plant in Adelaide is already biogas powered (when the generator runs).

All the best,

NASA's Morpheus test lander crashes and burns

�It features a new propulsion system with oxygen and methane, both considered green fuels that are better for the environment than the rocket fuels NASA usually uses. They could be manufactured on other planets as well, according to the space agency.

electro-microbiology,

Sewage-munching microbes to power plants

Microbes used to treat human waste might also generate enough electricity to power whole sewage plants, scientists hope.

The technology is based on the relatively new science of electro-microbiology, which is finding uses for the discovery that certain microbes can generate an electrical current outside their own cells

The same technique could see microbes used to generate biofuels, hydrogen gas, methane and other valuable chemicals from the cheap and abundant product of our trips to the bathroom, say Logan and fellow researcher Korneel Rabaey from the�University of Queensland.
