Novel Approaches to Manure
Summarized From Eastern Ontario Poultry Conference
October 17th, 2007
Poultry meat and egg farming is a predominantly non land-based production
enterprise. The management of waste represents a cost in a production
enterprise using animal waste as a fertilizer input. It is important
for the poultry enterprise to choose the equipment and management
style which will preserve the manure's fertilizing value. It is
important to encourage a business approach which will adapt a manure
treatment system to the practices and systems already in place.
If the manure leaves the farm, it becomes important to diminish
the volume of manure produced and also to facilitate manure handling.
Drying manure will more easily allow these two objectives to be
The SECONOV system is a technology that really dries manure. In
addition, this technology reduces odours and flies, reduces the
volume of manure to be managed and facilitates and reduces transportation
costs. Energy costs are reduced as well. The system requires a minimal
amount of maintenance all the while generating a high quality final
The SECONOV system can be adapted to existing henhouses and for
new poultry barns. Modular installation enables the size of the
farm to be adjusted. Furthermore, it makes enables pollution to
be combated at the source and makes it possible to store manure
for the medium and long-term.
Testing with models have demonstrated a 73 % reduction in odours.
The system allows for the evaporation of 70 grams of water per layer
per day from the manure minimizing ammonia los by 40 grams per layer
per year. The impact on a medium-sized farm with 22,398 hens represents
a daily evaporation of 1,540 litres of water and a reduced ammonia
loss of 880 kg per year which together impact positively on odour
Our company holds a permit from the Quebec Ministry of the Environment
to take on manure from outside our own farms. Our company also has
a North American patent allowing it to market the SECONOV drying
The challenge is to minimize and upgrade the by-product of the
annual digestion of some 300,000 tonnes of feed!
