The AGRISED project aims at demonstrate the suitability of dredged sediments to be used with no intervention or co-composted with green waste to produce innovative technosols usable in the reclamation of degraded land and brownfields and as innovative growing media for plant nursery.
The performance of the innovative sediment-based growing media and of reconstituted soil will be compared with the traditional land reclamation approaches and traditional growing media used for producing ornamental plants with high added value. The sediment/green waste co-composting process will produce growing media with better fertility, structure, water holding capacity, aeration, and biological activity than peat and coir pith.
Demonstration trials will be conducted growing plants with high added value for the European market: Fraser photinia and laurustinus.
The LCA and an economic analysis about the reuse of dredged sediments for the two production processes will be assessed, in order to asees the marketability and replicability of the proposed growing media for professional plant nursery and recontituted soil for soils restoration.
