A growing number of environmentally-minded poultry farmers in the United States, Canada and Australia are looking to peck away at their greenhouse gas emissions by transforming chicken dung into biochar fertilizer, as well as biogas and a form of bio-oil that can be used to run farm operations.
The resulting biochar – a charcoal like by-product — does double duty because it sequesters carbon and functions like a natural phosphorous/nitrogen/potassium fertilizer, says Mr. Fransham. The biofuels generated in the process can power heating and ventilation systems used in poultry operations, thus replacing the consumption of natural gas and electricity.
