Objective

Development of a bio-based plastic for the production of bottles.

The bottles that are made from this bio-based plastic will have to:

  • fulfil high technical standards for a wide range of applications;
  • be suitable for the challenging storage of cleaning agents and agricultural soil additives;
  • be both biodegradable and recyclable.

Tasks

Commercially available polyhydroxyalkanoates (PHA) and other bio-based plastics are compounded with various bio-based process additives. The blends that are produced in this way must:

  • meet the rheological requirement profile for the blow moulding process;
  • be sufficiently stable and unbreakable, as well as have a high impact strength;
  • have a high water vapour barrier and low CO2 and O2 permeability;
  • be able to be sterilized with gamma rays.

The bottles that are made of these bio-based plastics should, on the one hand, be degradable in both industrial composting as well as home composting, and, on the other hand, at least be able to be recycled using chemical processes.

Status Quo

There are already a small number of bottles made of bio-based plastics. These are bottles made of either polylactic acid (PLA) or bio-polyethylene terephthalate (bio-PET).

PLA bottles:

  • + high bio-based share,
  • + both biodegradable and recyclable,
  • + high mechanical resilience,
  • – low water vapour barrier, and can therefore only be used for a short period of time.

Bio PET bottles:

+ recyclable,

+ high mechanical resilience,

+ good water vapour barrier,

– low bio-based share (max. 30%),

– not biodegradable.

Advantages

Bottles made of PHA combine the advantages of PLA and bio-PET bottles:

  • + high bio-based share,
  • + both highly biodegradable and recyclable,
  • + high mechanical resilience,
  • + high water vapour barrier.
