Description
Within a context of development of methanization, this guide concerns good practices of digestate spreading. A first set of sheets addresses the main principles and stakes: methanization digestates and their agronomic interests (digestate formation and characteristics, agronomic properties), regulatory context, and environmental and technical-economic stakes related to digestate spreading (nitrogen emissions towards air and water, nitrogen cycle, input management and loss limitation, spreading cost, soil compaction). A second set of sheets addresses good practices: management of digestate input (calculations and good practices regarding nitrogen, phosphorus and organic matter), and use of the adequate material (for a better spreading uniformity, to avoid losses by volatilization, to avoid soil compaction)
Abstract (French)
La valorisation du digestat represente l'un des principaux facteurs cles de reussite d'un projet de methanisation. Mais dans le cycle de fonctionnement d'une unite, l'epandage du digestat cree encore des interrogations aupres des porteurs de projets, agriculteurs, conseillers, etc. Comment et quand l'epandre? Comment eviter la volatilisation de l'azote? Vaut-il mieux faire une separation de phase ou un autre post-traitement? Comment mettre en place le meilleur pilotage au champs? Face au constat de problematiques recurrentes au sein de la filiere agricole a ce sujet, le GT methanisation du Comite strategique de filiere 'Nouveaux Systemes energetiques' a pilote la redaction d'un guide pour fournir des bonnes pratiques a mettre en oeuvre pour l'utilisation des digestats en agriculture. Cet ouvrage fait un focus sur la methanisation agricole. A travers 5 fiches de synthese, vous pourrez en apprendre plus sur: les caracteristiques et les proprietes des digestats de methanisation agricole, la reglementation en vigueur, les enjeux environnementaux et technico-economiques lies a l'epandage du digestat, les bonnes pratiques pour piloter les apports de digestat, des conseils sur les types de materiel adequats
