he structural stability of soils is one of the major components of its

fertility (resistance to erosion and crust capping formation,

circulation of water and nutrients, physical protection for carbon,

etc…). Structural stability is impacted by organic waste landspeading,

and in particular, by digestate agronomic recovery. This impact is due

to combined biotic and non-biotic effects which are driven by

characteristics of carbon into the digestates. Anaerobic digestion leads

to the production of a digestate and its characteristics strongly vary

according to the substrates and the design criteria. The operational

objectives of the proposed work are: (i) to understand the main control

factors, within the anaerobic digestion process, of the impact of

digestates on structural stability of soils, and, (ii) to provide the

knowledge to allow the design and control the anaerobic digestion units

by taking into account the services provided by the digestates regarding

to structural stability of soils. The proposed work is based on the

combination of experimental tasks and modeling at the interface of

disciplines of process engineering and agronomy. To do this, a first

task will aim to develop a statistical model to predict the impact of

substrate cocktails and hydraulic retention time on carbonated

properties of digestates. A second task will carry out the development

of a model to predict the impact of digestates on the dynamic of the

structural stability of soils following landspreading. Finally, the last

task will aim at coupling both developed models. Hence, the obtained

numerical tool will allow the identification of the control factors,

within the digestion process, of the impact of digestates on the

structural stability of the soils.
