Centexbel built up expertise in solvolysis using Hansen solubility parameters to select the most suitable (environmentally friendly and sustainable) solvent. Knowledge has been built up on separating multilayer materials and extracting additives from polymer matrices (eg, flame retardants, stabilizers, plasticizers) to recover the purified polymer matrices for reuse in plastics processing.

Centexbel is still working on the (design4) recycling and separation of multi-layer materials and therefore uses different technologies such as specially developed adhesives, solvolysis, etc.
