Effluents from industrial pig farms cause an environmental challenge. While being good fertilizers, they pollute rivers and groundwater when overused on arable land. The ecological piggery of the Guernévez experimental station in Brittany, developed by researchers from the CNRS, the INRA and the chambers of agriculture of Brittany, has two particularities: it is equipped with a flushing system and it recycles the mixture of water and slurry which is daily evacuated from the building. This…

Breton pig production represents 56% of French national production. One of the consequences of this intensive livestock farming on a restricted territory is the excessive production of fertilizer products which causes environmental pollution, unbalances ecosystems and pollutes groundwater. The ecological pig farm located in Guernevez has set up, thanks to the work of researchers from the CNRS, INRA and the Chamber of Agriculture of Brittany, a system for recycling pig droppings by reproducing…
