BioSupPack: production and enzymatic recycling of environmentally safe packaging solutions


BioSupPack aims to deliver novel, cost-competitive and versatile bio-based packaging solutions based on PHAs (polyhydroxyalkanoates). These innovative materials are very good for packaging food, cosmetics, homecare and beverage products and do not harm the environment during or after use.

They achieve this by:

  1. Optimising PHA-based formulations, up to 85% of which comprise renewable resources
  2. Upscaling the different conversion processes as well as post-consumer waste sorting and recycling in line with the Industry 4.0 approach
  3. Broadening the range of rigid packaging applications: the formulations are combined with plasma technology or grafted coatings
  4. Integrating plasma technology into three points of the value chain (biomass pre-treatment, packaging production and packaging waste pre-treatment). This increases:
    • PHB (polyhydroxybutyrate) production yield,
    • PHB purity,
    • packaging performance (effective oxygen and water barrier), and
    • effectiveness and yield of enzymatic recycling.
  5. Demonstrating and increasing recyclability by:
    • setting up a real-time monitoring system for the selective separation of developed packaging after use
    • mechanical recycling of industrial scraps and selective enzymatic recycling of packaging waste, with final recovery of carbon sources for feedstock fermentation. The new packaging is environmentally safe and contributes to the circular economy
  6. Establishing a new value chain, including the development of logistics and management of both brewery and packaging waste.
Main results


  • increases the use of renewable resources (spent grain) for PHA formulations to up to 85%
  • crafts highly-performing PHA-based rigid packaging with properties similar to those of conventional petrochemical plastics
  • upscales the production of new PHA-based products to demonstration level
  • integrates plasma technology throughout the packaging treatment value chain
  • develops a system able to identify and sort BioSupPack waste (identifying up to 90% of BioSupPack materials)
  • ensures BioSupPack recyclability. Mechanical and enzymatic recycling processes will reintroduce materials into production and/or recover carbon sources for fermentation
  • creates a new value chain by managing both brewery and packaging waste flows.
