d2w® - Biodegradable plastic technology


d2w® technology turns ordinary plastic at the end of its useful life, in the presence of oxygen, into a material with a different molecular structure. At the end of the process, it is no longer a plastic, and has changed into a material which is biodegradable (by bacteria and fungi) in the open environment. In the same way as nature's wastes and much, much faster than ordinary plastic.


Stages of oxo-biodegration with d2w® technology:

  1. d2w® masterbatch is added at the manufacturing stage.
  2. Film containing d2w® is extruded and then converted into bags or packaging (or other single use products)
  3. The product behaves like conventional plastic during its intended service life.
  4. After its service life, the bag or packaging may end up in the open environment.
  5. The d2w® then takes effect and the product begins to degrade (in the presence of oxygen).
  6. The product will degrade and biodegrade in a continuous and irreversible process, leaving nothing but carbon dioxide, water and biomass.

Key benefits:

  • Biodegradable (according to ASTM D6954)
  • Looks and feels like ordinary plastic
  • d2w can be recycled with conventional polymer and can be made with recyclate
  • Suitable for food contact according to FDA & EU food contact regulations
  • No toxic residues or persistent microplastics
