Canadian food inspection agency (CFIA) manitoba composting exercise case study
Nordevco was invited to participate in a Canadian Food Inspection Agency (CFIA) composting exercise by the CFIA Manitoba Team. The purpose of Nordevco’s participation was to evaluate the impact of BactiDomus Technology on the composting process specifically related to achieving and maintaining temperatures appropriate for the inactivation of the pathogen responsible for avian influenza. The exercise took place at a layer barn in southwestern Manitoba on August 27, 2007.
The compost was created by mixing spent layers, poultry manure and straw in a total of nine batches (eight untreated and one treated with BactiDomus Technology). A Supreme Environment Processor 700T was used to mix the layers, manure, and straw before spreading the resultant compost mix on the concrete floor of the manure storage shed located behind the layer barn.
The resultant untreated compost pile was 64 feet long by 14 feet wide and approximately six feet high while the pile treated with BactiDomus Technology was 12 feet by 7 feet All data regarding the composition of the piles is based on data collected and provided by the CFIA Manitoba Team.
Once the compost piles were created probes were inserted into the piles to monitor temperatures. A total of 16 probes with two temperature readings per probe (32 temperatures) were inserted into the untreated compost pile. The probes were placed three feet from the end of the compost pile and then every 20 feet along one side of the pile. The probes were placed parallel to the floor at heights of one and a half and three feet up from the floor. Duplicate probes were placed one foot away horizontally from the other side of the pile.
