Summary
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 recycling system, inspired by nature, is an example of the solutions ecological engineering can offer to correct a problem caused by intensive farming practices.
