Bioplastic Made from...Cow Poo?
by Collin Dunn, Corvallis, OR, USA on 07.21.06
TreeHugger has seen it's share of bioplastics, used in everything from cutlery to packaging tape to baggies, and it's usually made from agricultural byproducts like corn or potato starch. A researcher in the Centre for Environmental Technology and Engineering in New Zealand has discovered another potential source for producing bioplastic: dairy-farm effluent, better known to most of us as cow poo in water. Dr. Steven Pratt is working on a way to turn carbon-based wastewater into a biodegradable, renewable form of plastic. The murky mixture he holds in the picture above is a mix of acids is produced by fermenting bacteria taken from wastewater ponds and fed with a glucose solution. Says the good doctor, "By using cheap and renewable sources there is a tremendous opportunity for biopolymer production to be made economic. At the same time, the problems of wastewater treatment and natural resource depletion are addressed.” ::Physorg.com via ::Hugg
Hey there....meet Hooman, who as has been part of the #1 radio morning show, "Sarah and No Name" on Alice @ 97.3, in the San Francisco Bay Area since August 1999.

And with his newly launched project, Hooman.TV he heads outs head out to the streets, to Fiji, to Hollywood and beyond to bring you the funniest, most entertaining videos of who's who, and what they have to say.
Hooman may have some late nights and early mornings partying until cows come home...BUT HERE, Hooman ventures out to the open pasture to examine a VERY important alternative energy source...first hand, so to speak!!! And it while its not pretty, its about powering up with cows, so we thought we would share...

For ages, cow's "excreta" traditionally have been used as manure in the fields, but it is also a source of viable energy- bio gas, which can reduce greenhouse emissions, significantly....read on..By capturing and storing CO2 from biogas into the ground, the biogas becomes carbon negative and scrubs our past CO2 emissions out of the atmosphere. NOW....IF you can't stand poo, you may NOT want to view, but if you are curious how cows currently power thousands of homes, check this out!
