It works for milk, so why not manure? Pasteurisation may be the next big
thing in the world of muck. Manure often contains pathogens such as
Cryptosporidium, which can leach into streams when the manure is spread
onto fields. So the US Department of Agriculture’s Soil Microbial Systems
Laboratory in Beltsville, Maryland, is testing a pasteurisation process that
mixes recycled materials such as cement, lime kiln dust, coal ash and gypsum
with the manure. This sparks off a chemical reaction that produces heat, ammonia
and a high-pH environment that kills the bugs.
