Pre-treatments of composites: mechanical and chemical pre-treatments must be applied on the target resins in order to increase the exposed surface to the enzymatic degradation.

Chemical modification of resins: identify the physico-chemical parameters that are influencing the enzymatic biodegradation of the resins and finely tune the resins components in order to introduce specific moieties that will favour the degradation.

Biodegradation processes will initially be studied in liquid medium using customised enzymes and low-molecular weight model compounds which contain all structural features of the target resins.

The aim is to determine how the enzymes attack corresponding bonds in the model compounds and what products are obtained.
