First pilot-scale tests completed for ViSS PHBV biopolymer production
Propagroup SpA and Helian Polymers BV collaborate on initial trials to validate processes for ViSS PHBV
As part of the ViSS project’s work on the demonstration plant for PHBV production, Propagroup SpA and Helian Polymers BV have successfully carried out the first pilot-scale tests aimed at developing and validating processes for the biopolymer transformation. The trials represent a crucial step in preparing the production of PHBV-based biopolymer prototypes in ViSS.
Conducted at Propagroup’s facilities in Turin, the testing phase involved the production of thin films and semi-flexible sheets using commercial PHA granule blends. The objective was to assess equipment setup and process parameters ahead of incorporating ViSS-produced PHBV granules into the final formulation. Thin films were manufactured through blown film extrusion using a three-layer extruder, while sheets for thermoforming applications were obtained via cast extrusion. Both processes serve as key benchmarks in validating the technical feasibility of the PHBV range.
These preliminary trials allowed for initial adjustments and structural optimisation of the production lines and laid the foundation for continued process refinement leading up to full-scale demonstration activities.
This milestone was made possible through the close collaboration between the teams at Propagroup and Helian Polymers. The work was carried out with the valuable contribution of Davide Crapanzano, Renato Mortera, Nydia Badillo Sampedro, Jon Donkers, Ron Kerkhoffs and Sofiya Vynnytska.
