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.
Applicants must have a Masters degree or equivalent qualification when the contract is signed.
