Dear Frank,

Pasteurization of Milk is carried out around 70 deg C ( hope I remember 
correctly ), when most of the bacteria are destroyed ( some bacteria must be 
surviving ).

My question is : Can composting happen naturally at 70 deg C ( ie. without 
any external heating to assist ) ?

If external heat is applied, what could be the maximum arrived temperature 
range for the compost pile ?

Best Regards,


Rajan
