permaculture

["Paul Osmond" <p_osmond@hotmail.com>]

Depends on the particular composting technology being used as well as the 
degree of process control employed. 55-65 degrees C is common for mid- and 
large-scale aerobic composting, but some in-vessel systems can generate 
temperatures in excess of 80 degrees.

Maintenance of temperatures >55 degrees for at least 3 days is necessary to 
enable pasteurisation - this is achieved through ensuring appropriate levels 
of moisture and aeration and correct carbon:nitrogen ratio.

Check out www.recycledorganics.com (University of New South Wales Recycled 
Organics Unit web site) for extensive online information on the technical 
and other aspects of composting, including links to range of other 
specialist sites.
