Laminated glass interlayer separation: Saint GobainRecent Research Landscape

Contamination from bonded non-glass components prevents high-purity flat glass recovery, which is mitigated through engineered separation of the interlayer film. This enables the recovery of high-value cullet from complex glazing assemblies.

What technical problems is Saint Gobain addressing in Laminated glass interlayer separation?

Interlayer material adhesion persistence

(3)evidences

Strong bonding between glass and polymer interlayers prevents efficient material recovery and sorting. Overcoming this adhesion allows for the reclamation of high-purity glass fragments and polymer films.

Irreversible component bonding

(1)evidences

Loss of structural integrity at the polymer-glass boundary leads to delamination and safety hazards. Maintaining a permanent bond prevents moisture ingress and glass shard dispersal during impact.
