Evaluation et réduction des risques de contamination par des polluants organiques dans le contexte de l’usage de Produits Résiduaires Organiques sur sols agricoles (Sabine Houot)

Descriptif :

L’objectif est de contribuer à la maitrise des risques environnementaux et sanitaires liés à la  contamination des sols et des eaux circulant dans les sols (transfert eaux souterraines) par des polluants organiques (PO) introduits dans le sol par des produits résiduaires organiques (PRO) utilisés en agriculture.

Après l’évaluation des risques associés aux pratiques actuelles d’épandage, l’efficacité de traitements biologiques et physico-chimiques de plus en plus poussés de produits résiduaires organiques, représentatifs des principales familles épandues et reconnues comme potentiellement vecteurs de PO (par exemple boues d’épuration urbaine, lisiers, biodéchets des ménages,…), sur la nature et l’intensité de ces risques de contamination sera évaluée.

Le projet pourrait être centré sur 4 filières de traitement et l’épandage direct comme traitement témoin: épandage direct, digestion anaérobie (premier mode de traitement biologique testé), compostage (second mode de traitement biologique), couplage digestion-compostage (couplage des 2 modes de traitement biologique), séchage thermique ou solaire (efficacité d’un traitement non biologique).
