The term 'bioplastics' covers a broad range of polymers that
each have different attributes with regard to their impact on the
environment. At Corbion Purac, we believe that bioplastics should
be made from renewable, sustainable resources, which can then be
recycled in a closed loop system.
The following categories demonstrate our view on the different
types of bioplastics available today:
Biobased: both compostable/biodegradable and non-
These plastics are made from biobased, renewable resources and
can be either biodegradable/compostable or non-compostable and
They can be used for almost any application, such as molded parts,
foam & film. Plastics in this category: PLA, PHA, Bio PA
& high heat PLA.
Made from fossil fuels: compostable
Contrary to popular belief, some plastics labelled as
'bioplastics' are actually made from fossil fuels. They are,
however, compostable, which grants them their 'bio' status.
Plastics in this category include PBAT.
Made from fossil fuels: oxo-degradable
These plastics are not only made from fossil fuels, but they
fragment into micro-plastic pieces which cannot further degrade.
These plastics are said to be worse for the environment than
traditional plastics and even do
'more ecological harm than good'1.
