Abstract:
The livestock industry must find a low cost way to
determine odor and gas emissions from production sites
to respond to increasing public pressure and new
regulations. Producers seeking technologies to reduce
emissions need accurate methods of quantifying those
reductions. Field emission measurement techniques are
time-consuming and expensive. And, because field
measurements are site-specific, the emission data cannot
readily be transferred to other sites with different
manure management systems, genetics, diets, animal
management programs, etc. Modeling to predict odor and
gas emissions is a fast, economical approach to
determining these emissions. However, current equations
used to determine the rate of gas transfer from aqueous
solutions of manure must first be validated.
This research effort will include controlled laboratory
experiments to validate the use of mass transfer models
and coefficients for manure gas emission predictions.
Specific objectives are to: (1) develop an accurate,
quick, inexpensive laboratory technique to determine
emission rates; (2) test applicability of existing
mass-transfer models for predicting emission rates; and
(3) identify and prioritize key odorous organic
compounds emitted from manure.
The long-term goals are to: (1) produce an economical
method for quantifying actual emissions from individual
area sources for regulatory purposes; (2) increase the
accuracy and availability of technologies that can be
used to compare and quantify emission reductions
generated by odor control technologies; and (3) improve
the ability of producers to manage odors and improve air
quality in their communities.
