Impact on other gases undetermined |
Urine and feces, combined can form ammonia which
is a PM 2.5 particulate. Efforts to separate urine and feces immediately
upon excretion have reduced ammonia emissions successfully. Manure
handling systems designed to prevent urease from coming into contact
with urea are under investigation. Most systems employ a separator
or a belt conveyor whereby feces, containing urease, are captured
on the belt and urine is stored below. A much as 80 percent reduction
in ammonia emissions is expected from using this system but the
practice has not yet been commercially implemented. However, several
urine/feces segregation systems are in the developmental phase
at this time.
