Certain pig manure management operations (e.g., stirring the manure and opening the manure pit) can allow considerable amounts of greenhouse gases to escape. Depending on their scale, these fugitive emissions could limit the value of airtight manure pits equipped with treatment systems unless corrective measures are taken to significantly reduce them. The main goal of this project is to document emissions, determine whether these measures are necessary, and issue recommendations on what measures should be taken.
The project consists of characterizing and quantifying the following greenhouse gas emission sources over two years:
In situ methods are being used to sample and measure the emissions.

When designing tanks, the total volume of material to be stored must be calculated. This guide provides a comprehensive calculation method that takes into account volumes of bedding added as well as feed and water losses.
